Shivani Singh Chauhan presented a seminar on the Global Positioning System (GPS) to faculty at Govt. Girls Polytechnic. The presentation covered an overview of GPS, including its architecture, how it works using satellite geometry and signal triangulation, sources of errors, other global navigation systems, and applications. GPS is a satellite-based system consisting of 24 orbiting satellites used to determine location by calculating distance from satellites using radio signals. It has uses in navigation, mapping, military operations, and more.
It depicts the basic information about GPS technology and its various uses in engineering and other fields. May be useful for students of engineering and for presentation.

Global Positioning System (GPS) is the only system today able to show one’s own position on the earth any time in any weather, anywhere. This paper addresses this satellite based navigation system at length. The different segments of GPS viz. space segment, control segment, user segment are discussed. In addition, how this amazing system GPS works, is clearly described. The various errors that degrade the performance of GPS are also included. DIFFERENTIAL GPS, which is used to improve the accuracy of measurements, is also studied. The need, working and implementation of DGPS are discussed at length. Finally, the paper ends with advanced application of GPS.
GPS helps us identify exact location of a place/feature in the globe. Now-a-days we can carry out survey, enter data and process data. GPS is very helpful in soil survey

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

4. What is GPS:
It is a satellite-based navigation system.
Made up of a network of 24 satellites circulating around
earth orbit by the U.S. department of defense (USDOD).
The first satellite was developed in 1960 to allow ships in the
U.S. Navy to navigate the oceans more accurately.
GPS was originally intended for military applications, but in
the 1980, the government made the system available for
civilian use.
GPS permits land, sea, and airborne user to determine their
three-dimensional position, velocity and time.
5. Architecture of GPS:
To run all the system of GPS technology properly, highly advance architecture
of GPS has been developed that includes three major segments called the space
segment, control segment and a user segment.
6. Three Segments of GPS-
Minimum of 24 satellites
(currently 32) in orbit around
earth at altitude 20,000 km.
It transmit radio-navigation
signals, and store and
retransmit the navigation
message sent by the control
segment.
a) Space Segment
7. combination of a master
control station, four dedicated
ground antennas and six
dedicated monitor stations.
responsible for the proper
functioning of all the
operation of GPS such as
changing unhealthy satellite
with a healthy one.
b) Control Segment
8. c) User Segment
Comprises of thousand of
U.S. and military users who
uses the secure GPS precise
Positioning service, and
millions of civil, commercial
and scientific users .
9. How does GPS works:
Each satellites broadcast radio signals with their location and
time.
GPS receivers receives radio signals, and used these data to
calculate its distance from at least four satellites.
Distance=Speed * Travel time
GPS radio signals are travel at the speed of light .
Both satellites and receiver generate the same psuedocode
signals.
Difference b/w the 2 signals is the travel time.
Then the receiver uses Trilateration method to define its exact
location on Earth.
10. If we know the distance b/w the satellite and the receiver for:
1 satellite, the receiver’s location is known within a sphere.
Trilateration Process
12. 3 satellite, the receiver’s location is somewhere on at most two 3D
regions.
13. 4 satellite, the region gets smaller because of the sphere of the new
satellite.
14. GPS Satellite Geometry:
Satellite Geometry can affect the quality of GPS signals and
accuracy of receiver trilateration.
Position Dilution of Precision (PDOP) is the DOP value used
most commonly in GPS to determine the quality of a
receiver’s position.
It’s usually depend on the GPS receiver to pick satellites
which provides the best position triangulation.
15. If the satellites are well separated and equally apart from each
other it will form a well sphere and give less intersection point and
receiver can get an accurate result.
Two Types of Satellite Geometry
a) Ideal Satellite Geometry-
16. Poor satellite geometry are formed when satellites are not equally
apart to each other and provide more intersection area of receiver’s
position resulting inaccurate position.
b) Poor Satellite Geometry-
17. Sources of GPS Error:
Source Amount Of Errors
Satellite clocks: 1.5 to 3.6 meters
Orbital errors: <1 meter
Ionosphere: 5 to 7 meters
Troposphere: 0.5 to 0.7 meters
Multipath: 0.6 to 1.2 meters
Selective Availability: (depends on USDOD)
User errors: Up to a kilometer or more
18. Other Satellite Navigation System:
GLONASS- Russia’s global navigation system. Fully operational worldwide.
Galileo- Developed by the European Union and other partner countries,
planned to be operational by 2016 (and fully operated by 2020).
Beidou- People’s Republic of China’s regional system, currently limited to
Asia and west pacific.
COMPASS- People’s Republic of China’s global system, planned to be
operational by 2020.
IRNSS- India’s regional navigation system, covering India and Northern
Indian Ocean: GPS Aided GEO Augmented Navigation (GAGAN).
QZSS- Japanese regional system covering Asia and Oceania.
19. Applications:
In-vehicle Navigation (car, boat, aircraft etc.)
Weather and Traffic Alerts
Geologic Research and Mining
Military Navigation (Intelligence and target locations, Weapon Aiming)
Mapping and Surveying
Precision Agriculture
Robotics (Self navigating and Autonomous robots)
Tectonics (motion measurement of earthquakes)
Recreation (Geocaching ,Geodashing, way marking and location based
mobile games)
20. Conclusion:
The applications using GPS are constantly growing.
More reliable and accurate measurements.
The cost of the receiver is dropping.
More affordable and accessible to consumers.
