Parabolic antenna alignment system with Real-Time Angle Position FeedbackStevenPatrick17
Introduction
Parabolic antennas are a crucial component in many communication systems, including satellite communications, radio telescopes, and television broadcasting. Ensuring these antennas are properly aligned is vital for optimal performance and signal strength. A parabolic antenna alignment system, equipped with real-time angle position feedback and fault tracking, is designed to address this need. This document delves into the components, design, and implementation of such a system, highlighting its significance and applications.
Importance of Parabolic Antenna Alignment
The alignment of a parabolic antenna directly affects its performance. Even minor misalignments can lead to significant signal loss, which can degrade the quality of the received signal or cause communication failures. Proper alignment ensures that the antenna's focal point is accurately directed toward the signal source, maximizing the antenna's gain and efficiency. This precision is especially crucial in applications like satellite communications, where the antenna must track geostationary satellites with high accuracy.
Components of a Parabolic Antenna Alignment System
A parabolic antenna alignment system typically includes the following components:
Parabolic Dish: The primary reflector that collects and focuses incoming signals.
Feedhorn and Low Noise Block (LNB): Positioned at the dish's focal point to receive signals.
Stepper or Servo Motors: Adjust the azimuth (horizontal) and elevation (vertical) angles of the antenna.
Microcontroller (e.g., Arduino, Raspberry Pi): Processes sensor data and controls the motors.
Potentiometers: Provide feedback on the antenna's current angle positions.
Fault Detection Sensors: Monitor for potential faults such as cable discontinuities or LNB failures.
Control Software: Runs on the microcontroller, handling real-time processing and decision-making.
Real-Time Angle Position Feedback
Real-time feedback on the antenna's angle position is essential for maintaining precise alignment. This feedback is typically provided by potentiometers or rotary encoders, which continuously monitor the azimuth and elevation angles. The microcontroller reads this data and adjusts the motors accordingly to keep the antenna aligned with the signal source.
Fault Tracking in Antenna Alignment Systems
Fault tracking is vital for the reliability and performance of the antenna system. Common faults include cable discontinuities, LNB malfunctions, and motor failures. Sensors integrated into the system can detect these faults and either notify the user or initiate corrective actions automatically.
Design and Implementation
1. Parabolic Dish and Feedhorn
The parabolic dish is designed to reflect incoming signals to a focal point where the feedhorn and LNB are located. The dish's size and shape depend on the specific application and frequency range.
2. Motors and Position Control
Stepper motors or servo motors are used to control the azimuth and elevation of

2. Introduction
Basic webmaster duties usually consist of
maintaining a site's web pages by checking
regularly the files on the server and the
database. When tasked to do this a webmaster
is expected to understand how a website
functions, what web host services were being
used (i.e. emailing, subdomains, etc.), and
what are the requirements for running the site
(i.e. Apache, MySQL and PHP). As a way of
introducing you to webmastering, we start
with the basics of web hosting, domain names,
programming languages and databases.
3. Definition of Terms
DNS – Domain Name System
is a hierarchical naming system
that serves as the "phone book"
for the Internet by translating
human-friendly computer
hostnames into IP addresses.
Domain Name – provides a
symbolic representation, such as
recognizable names, to mostly
numerically addressed Internet
resources. Multiple IP addresses
can be assigned to one domain
name.
FTP – a File Transfer Protocol
for exchanging and
manipulating files over a TCP
computer network. An FTP
client may connect to an FTP
server to manipulate files on that
server.
ISP – Internet Service
Provider; also called Internet
Access Provider or IAP. It is a
company that offers its
customers access to the Internet.
4. Definition of Terms
URL - Uniform Resource
Locator specifies where an
identified resource is available
and the mechanism for
retrieving it. Also known as
Web Address.
Web Server – either a software
that serves as platform on which
web applications can run or a
hardware from which web
applications or files can be
accessed by other computers in
a network.
Web Host - Web hosts are
companies that provide space on
a server they own for use by
their clients as well as providing
Internet connectivity, typically
in a data center.
Server-Side Scripting
Languages – some common
examples are ASP/ASP.NET
(*.asp/*.aspx), ColdFusion
Markup Language (*.cfm), Java
via JavaServer Pages (*.jsp),
PHP (*.php)
5. Web Servers
At the most basic level, a server is a technology solution that “serves”
files, data, print, fax resources, and more to multiple computers.
The word “server” often refers to the specialized computer (or
hardware) that the server software runs on. The server is optimized to
perform services for other computers or “clients.” Clients can be
computers as well as printers, faxes, or other devices that connect to
the server.
6. Web Hosting
At its core, a Web server serves static content to a Web browser by
loading a file from a disk and serving it across the network to a user's
Web browser. This entire exchange is mediated by the browser and
server talking to each other using HTTP.
Some companies that own computers acting as web servers often offer
web hosting services
Web hosting is a service which allocates space for customers to
showcase their websites on computer servers that are connected to the
Internet 24/7.
7. Major Types of Web Hosting
Free web hosting service: Free, (sometimes) advertisement-
supported web hosting, and is often limited when compared to paid
hosting.
Good: Low cost. It's free. Good for family, hobby or
personal sites. Free email is often an option.
Bad: No domain names. Few, limited, or no software
options. Limited security options. Limited or no database
support. Limited technical support.
8. Major Types of Web Hosting
Shared web hosting service: One's website is placed on the same
server as many other sites, ranging from a few to hundreds or
thousands. Typically, all domains may share a common pool of server
resources, such as RAM and the CPU. The features available with this
type of service can be quite extensive. A shared website may be
hosted with a reseller.
Good: Low cost. Cost is shared with others. Good for small
business and average traffic. Multiple software options.
Own domain name. Good support.
Bad: Reduced security due to many sites on one server.
Restrictions on traffic volume. Restricted database support.
Restricted software support.
9. Major Types of Web Hosting
Virtual Dedicated Server: Dividing a server into virtual servers,
where each user feels like they're on their own dedicated server, but
they're actually sharing a server with many other users. The users may
have root access to their own virtual space. This is also known as a
virtual private server or VPS. Customers are sometimes responsible
for patching and maintaining the server.
Good: Low cost. Cost is shared with others. Good for small
business and average traffic. Multiple software options.
Own domain name. Good support.
Bad: Reduced security due to many sites on one server.
Restrictions on traffic volume. Restricted database support.
Restricted software support.
10. Major Types of Web Hosting
Dedicated hosting service: the user gets his or her own Web server
and gains full control over it (root access for Linux/administrator
access for Windows); however, the user typically does not own the
server. Another type of Dedicated hosting is Self-Managed or
Unmanaged. This is usually the least expensive for Dedicated plans.
The user has full administrative access to the box, which means the
client is responsible for the security and maintenance of his own
dedicated box.
Good: Good for large business. Good for high traffic.
Multiple domain names. Powerful email solutions.
Powerful database support. Strong (unlimited) software
support.
Bad: Expensive. Requires higher skills.
11. Major Types of Web Hosting
Colocation web hosting service: Similar to the dedicated web hosting
service, but the user owns the server; the hosting company provides
physical space that the server takes up and takes care of the server.
This is the most powerful and expensive type of web hosting service.
In most cases, the colocation provider may provide little to no support
directly for their client's machine, providing only the electrical,
Internet access, and storage facilities for the server. In most cases, the
client would have his own administrator visit the data center on-site to
do any hardware upgrades or changes.
Good: High bandwidth. High up-time. High security.
Unlimited software options.
Bad: Expensive. Requires higher skills. Harder to
configure and debug.
12. Other Types of Web Hosting
Reseller web hosting: allows clients to become web hosts
themselves. Resellers could function, for individual domains, under
any combination of these listed types of hosting, depending on who
they are affiliated with as a provider. Resellers' accounts may vary
tremendously in size: they may have their own virtual dedicated server
to a colocated server. Many resellers provide a nearly identical service
to their provider's shared hosting plan and provide the technical
support themselves.
13. Other Types of Web Hosting
Managed hosting service: The user gets his or her own Web server
but is not allowed full control over it (root access for
Linux/administrator access for Windows); however, they are allowed
to manage their data via FTP or other remote management tools. The
user is disallowed full control so that the provider can guarantee
quality of service by not allowing the user to modify the server or
potentially create configuration problems. The user typically does not
own the server. The server is leased to the client.
14. Other Types of Web Hosting
Clustered hosting: having multiple servers hosting the same content
for better resource utilization. Clustered Servers are a perfect solution
for high-availability dedicated hosting, or creating a scalable web
hosting solution.
Grid hosting: this form of distributed hosting is when a server cluster
acts like a grid and is composed of multiple nodes.
Home server: usually a single machine placed in a private residence
can be used to host one or more web sites from a usually consumer-
grade broadband connection. These can be purpose-built machines or
more commonly old PCs. Some ISPs actively attempt to block home
servers by disallowing incoming requests to TCP port 80 of the user's
connection and by refusing to provide static IP addresses. A common
way to attain a reliable DNS hostname is by creating an account with a
dynamic DNS service. A dynamic DNS service will automatically
change the IP address that a URL points to when the IP address
changes.
15. Specific Types of Web Hosting
File hosting service: hosts files, not web pages e.g. RapidShare,
Megaupload
Image hosting service: hosts images e.g. Flickr, Photobucket, Picasa
Video hosting service – hosts videos e.g. YouTube, Vimeo
Blog hosting service – hosts blogs using blog CMS e.g. Blogger,
Wordpress.com, Xanga, LiveJournal
One-click hosting – allows upload of large files and sends a URL of
the file to other users for download e.g. YouSendIt, DropBox
Shopping cart software – software is hosted and application use is
rented out as a service; no installation needed, e.g. Basket2go.net
17. Domain Names
Domain names are often referred to simply as domains and domain
name registrants are frequently referred to as domain owners, although
domain name registration with a registrar does not confer any legal
ownership of the name, only an exclusive right of use.
Simply registering a domain name does not protect you if another
company files a trademark infringement claim — if they hold a legal
trademark, you can lose your domain name and even find yourself
liable for the owner's legal costs.
Domain names are restricted to the ASCII letters a through z (case-
insensitive), the digits 0 through 9, and the hyphen, with some other
restrictions in terms of name length and position of hyphens.
18. Differences Between
URL: http://www.example.net/index.html
Domain name: www.example.net
Registered domain name: example.net
The hypertext transfer protocol (HTTP) specifies that the client tells the
server which name is being used. This way, one server with one IP
address can provide different sites for different domain names (virtual
hosting). For example, the server at IP address 208.77.188.166
handles all of the following sites: example.com, www.example.com,
example.net, www.example.net, example.org, www.example.org
19. Parts of a Domain Name
A domain name usually consists of two or more parts (technically a
label), which is conventionally written separated by dots, such as
example.com.
The rightmost label conveys the top-level domain (for example, the
address www.example.com has the top-level domain com).
Each label to the left specifies a subdivision, or subdomain of the
domain above it. Note: “subdomain” expresses relative dependence,
not absolute dependence. For example: example.com is a subdomain
of the com domain, and www.example.com is a subdomain of the
domain example.com.
A hostname refers to a domain name that has one or more associated
IP addresses; ie: the 'www.example.com' and 'example.com' domains
are both hostnames, however, the 'com' domain is not.
20. Types of Domain Names
Generic Top-level domains (gTLD):
Generic:.com, .net and .org, .info, .biz, .name, .pro
Sponsored: .gov, .edu, .asia, .mobi
Country-Code Top Level Domains (ccTLD):
e.g.: .co.uk, .ph, .us
Second-Level Domain Names – to the left of TLDs
Domain Hacks – unconventional use of TLDs to
make it part of the website's title
e.g.: del.icio.us, ma.gnolia.com
21. Domain Name Registration Info
Administrative contact - has the highest level of control over a domain
Functions : management of all business information, such
as name of record, postal address, and contact information
of the official registrant of the domain and the obligation to
conform to the requirements of the domain registry in order
to retain the right to use a domain name, and installs
additional contact information for technical and billing
functions.
Technical contact - manages the name servers of a domain name.
Functions : assuring conformance of the configurations of
the domain name with the requirements of the domain
registry, maintaining the domain zone records, and
providing continuous functionality of the name servers (that
leads to the accessibility of the domain name).
22. Domain Name Registration Info
Billing contact - responsible for receiving billing invoices from the
domain name registrar and paying applicable fees.
Name servers - Domains usually need at least two authoritative
name servers that perform name resolution for the domain. If they
are not automatically provided by the registrar, the domain holder
must specify domain names and IP addresses for these servers.
What is a Subdomain?
This is what other people refer to as “third-level domain.” No need to register.
Also used to identify two different IP addresses on the same server (machine
names). It is also used to point to different computers with the same
information (load balancing).
Scalability of a domain allows for multiple subdomains to be created. It helps
in organizing information. Subdomains allow better hosting options as
compared to subdirectories.
23. How To Register A Domain Name
Select a unique easy-to-remember name. Underscores are okay
as well as dashes. It must be at least two characters long and no
more than 63 characters maximum, excluding the top level
domain. The first and last character cannot be a hyphen.
Domain names are not case-sensitive.
Check with Whois.net whether it's available or not. There are
other free whois tools online that can help you find an available
domain name. Some good domain names are often taken and
you might want to consider buying these from the owner if they
are for sale, or you can buy expired domains which the owners
didn't renew after a year.
24. How To Register A Domain Name
• If it's available, then choose your domain name extension. The most
popular top-level domains may cost higher than the less used ones.
• Go to checkout and pay for your domain name. You can use either
PayPal or a Credit Card.
• Edit your account at the domain registrar site to reflect the domain
name servers (at least 2) to point your domain to. These domain
name servers (DNS) are provided by your web host and are needed
to help translate numerical IP addresses to human-readable domain
names.
25. What are Domain Name Servers?
Name servers do two things all day long:
They accept requests from programs to convert domain names into IP addresses.
They accept requests from other name servers to convert domain names into IP
addresses.
When a request comes in, the name server can do one of four things with it:
It can answer the request with an IP address because it already knows the IP address
for the domain.
It can contact another name server and try to find the IP address for the name
requested. It may have to do this multiple times.
It can say, "I don't know the IP address for the domain you requested, but here's the
IP address for a name server that knows more than I do."
It can return an error message because the requested domain name is invalid or does
not exist.
26. What are the server requirements?
Server requirements will depend on the type of server
platform to use and the languages it can handle
The most common web server software is Apache for Unix
and Linux servers, followed by Windows IIS.
Most websites use PHP and HTML to serve web pages. For
dynamic sites, you might need to create databases using
MySQL to manage content all throughout your site.
PHP and MySQL go hand-in-hand like peanut butter and
jelly.
27. Programming Languages and Databases
The most common database for a web server is MySQL, which is a
free open-source database system. MSSQL, PostgreSQL and GNU
SQL are also popular SQL servers.
Be sure that the PHP on the server is up to date, otherwise PHP scripts
may not function properly. PHP 5.2 is the newest version.
If you want to study PHP, you can read tutorials at PHP.net
phpMyAdmin is a free software tool written in PHP intended to
handle the administration of MySQL over the Web. Available for
download at phpmyadmin.net
CSS (Cascading Style Sheets) and AJAX ( Asynchronous Javascript
And XML) are just web development techniques.
28. Information Technology Skills Needed
• The most searched for and the most blogged among web
programming languages are Java, PHP and Javascript. Java is
used often for software and applications development. PHP
and Javascript are used for web development projects.
• As of 2008, the top back end programming languages and
frameworks used are PHP, Javascript, ASP.NET, Python,
Ruby, Java, ASP and ColdFusion.
• Commonly used frameworks include Ruby on Rails (the
single most used framework), Django, Python, Zend (the
most commonly used PHP framework) and CakePHP. Other
frameworks include Java Struts, CodeIgniter for PHP, and
Java Spring.
29. Web Host Management
Web hosts provide graphical user interface (GUI) software
for easy management of one's site. Examples of these GUI
are cPanel (www.cpanel.net) and Plesk.
For easy website creation many companies have created
content management software for blogs, forums and websites.
Examples of CMS are Wordpress, Drupal, Joomla, phBB (for
forums), BoonEx Dolphin (for social networking sites) and
Blogger.
For local installations, you can use XAMPP which you can
download at apachefriends.org
XAMPP can be installed in almost all types of OS (i.e.
Windows, Linux, Solaris and Mac OS X)
