Global Positioning System (GPS) is a satellite based navigation system that can provide people who use it with their exact position on Earth, tell them how to get to another location, how fast they are moving, where they have been, how far they have gone, what time it is. GPS was originally designed to help the U.S. military with finding the accurate location of their soldiers, vehicles, planes and ships around the world. Now, GPS is used in cellular phones, navigation and map making.
Space segmentsGPS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20,200 km (12,550 miles). Each satellite circles the Earth twice a day.The satellites in the GPS constellation are arranged into six equally-spaced orbital planes surrounding the Earth. Each plane contains four "slots" occupied by baseline satellites. This 24-slot arrangement ensures users can view at least four satellites from virtually any point on the planet.
The control segment
The control segment of the GPS system consists of a worldwide network of tracking stations.
The master control station (MCS) located in the United States at Colorado Springs, Colorado.
The primary task of the operational control segment is tracking the GPS satellites in order to determine and predict satellite locations, system integrity, behavior of the satellite atomic clocks, atmospheric data, the satellite almanac, and other considerations.
The User segment
The user segment includes all military and civilian users. With a GPS receiver connected to a GPS antenna, a user can receive the GPS signals, which can be used to determine his or her position anywhere in the world. GPS is currently available to all users worldwide at no direct charge.
How it work?When a GPS receiver is first turned on, it downloads orbit information from all the satellites called an almanac.Once this information is downloaded, it is stored in the receiver’s memory for future use. The GPS receiver calculates the distance from each satellite to the receiver by using the distance formula: distance = velocity x time.The receiver determines position by using triangulation. When it receives signals from at least three satellites the receiver should be able to calculate its approximate position (a 2D position). The receiver needs at least four or more satellites to calculate a more accurate 3D position. The position can be reported in latitude/longitude.
The two GPS codes are;-
Coarse acquisition (or C/A-code)
Precision (or P-code).
The C/A-code is modulated onto the L1 carrier only, while the P-code is modulated onto both the L1 and the L2 carriers. This modulation is called biphase modulation, because the carrier phase is shifted by 180° when the code value changes from zero to one or from one to zero.
Source of GPS error
Satellite clock errors: Caused by slight discrepancies in each satellite’s four atomic clocks. Errors are monitored and corrected by the Master Control Station.
Orbit errors:Satellite orbits.

ARCHITECT: FRANK LLOYD WRIGHT
YEAR: 1937-1959
Since its first prolonged stay in Arizona during 1927, Wright had hoped to return to this region of the Sonoran desert, to escape the severe winter of Wisconsin. Finally, in 1937, with his wife traveled to Phoenix to find an area in which to build his home studio, which even today remains useful as housing, work-site installation and education.
Concept
Taliesin West was built to coexist in harmony with its desert environment, using local materials such as rocks and sand in the design of the structure and substance of the desert that surrounds the entire complex by its structural diversity are combining into a single Complete.
Wright wrote: “Our new desert camp belonged to the Arizona desert as though it had stood there during creation.”

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

7. •Since earliest time, Some of the earliest techniques that travellers used were simple rock
cairns marking the trail, either for finding their way back, repeating their path, or for
others to follow. This technique is still used today. The problems with it, however, are
obvious.
•A better method was to record this spatial information, We call these maps. The first
recorded maps date back to the Mesopotamians some 5,000 years ago, constituting a
revolution in geographic positioning that has enjoyed widespread use ever since.
•Today, we live in a world of precision. We expend great amounts of intellectual and
monetary currency on ever-smaller units of measurement. Knowledge of where we are and
where we are going has, for the past several thousand years, relied on highly trained and
skilled surveyors. The science of surveying has achieved phenomenal levels of precision.
INTRODUCTION
8. GPS means
• A space-based satellite navigation system provides location
and time information in all weather.
• Maintained by the United States government and is freely
accessible by anyone with a GPS receiver.
WHAT IS GPS?
9. Official name : “NAVIGATIONAL SATELLITE TIMING AND
RANGING GLOBAL POSITIONING SYSTEM”
(NAVSTAR GPS)
• Consists of 30+ GPS satellites in medium Earth orbit
(2000km - 35,000 km).
• Made up of two dozen satellites working in harmony are known
as a satellite constellation
• Mainly used for navigation, map-making and surveying.
24. HOW DOES IT WORKS?
GPS satellites circle the earth twice a day in a very
precise orbit and transmit signal information to earth.
GPS receivers take this information and use
triangulation to calculate the user's exact location.
GPS receiver compares the time at signal was
transmitted by a satellite with the time when it was
received user's position and display it on the unit's
electronic map.
A GPS receiver must be locked on to the signal of at
least three satellites to calculate a 2D position (latitude
and longitude) and 3D position.
25. GPS: HOW DOES IT WORK?
MORE SATELLITE EQUALS BETTER RESOLUTION
27. APPLICATIONS
GPS is considered a dual-use technology, meaning it has
significant military and civilian applications
Conflicting Interests
Military needs a secure system
Civilians need unrestricted access
GPS IN RAIN FOREST GPS ON BATTLE FIELD
29. APPLICATIONS
Tracking Devices:
One of the easiest applications to consider is the simple GPS tracking devises.
Navigation:
• Speed GPS’s calculate your ground speed as you walk, run, drive or fly.
Elevation:
In addition to providing you with your latitude and longitude, GPS provides you
with altitude information.
Intelligent Vehicle Highway Systems (IVHS):
IVHS will combine GPS technology with communications, controls, navigation
and information systems to improve highway safety, ease trace congestion, and
reduce harmful environmental effects.
Car Navigation Systems:
A car navigation system uses a specialized computer that use the signals from GPS
satellites to track the driver's progress on a digital map. It may provides services
like the shortest route, etc.
30. Geographic Information Systems (GIS) :
GPS technology is used extensively in geographic information systems. These
systems combine cellular data networks for communication.
Aviation:
GPS technology is being applied in aircraft safety systems, air traffic control
system, and zero visibility landing.
GPS technology can be used to plot aircraft altitude to a pitch of one-tenth of
one degree. In future, it is expected to reduce the number of people required in
the control tower and cockpit.
APPLICATIONS
31. ADVANTAGES OF GPS
Intervisibility between different stations not required
Not dependent on weather conditions, day or night.
Positional accuracy irrespective of network geometry acts
as a function for two or more different station distance.
Homogeneous accuracy affects geodetic network planning
and could easily establish point with the sites where
stations are not visible e.g. mountains.
Comparatively more flexible, consuming less time and also
more effective.
High accuracy with 3-dimensional geographic information
irrespective of place and time
32. DISADVANTAGES OF GPS
GPS chip is power hungry which drains battery in 8 to 12 hours.
This requires either battery replacement or recharge.
GPS signal does not pierce through the solid walls or structures. Moreover it is affected by
large buildings or structures.
Due to this, user will not be able to utilize GPS service in indoors or under water or in
dense tree regions or in underground stores or places etc.
GPS accuracy depends on sufficient received signal quality.
GPS signal gets affected due to multipath, atmosphere (i.e. ionosphere), electromagnetic
interference etc. This leads to error of about 5 to 10 meters in GPS signal.
Though currently system is managed by US DoD and users are utilizing the system free of
cost, it is in the hand of US to allow or deny the GPS service at anytime.
It is better not to rely completely on GPS system. Backup travel maps with directions will
help in the event of GPS system failure.
33. CONCLUSION
Previously this service of GPS was confined only the
military and Law enforcements agencies, but now this
is a extended for civilian. GPS provided good
substitute for route mapping in navigation. GPS has
truly helped man to advance in more ways than one. It
is also going to bring a great revolution by its
development. The future will hold a lot more
surprises. Automobiles are tested on moving on their
own without the assistance of a driver.
