Key Structure Of GPS

GPS consists of the following three sections.

• Space segment (GPS satellites): A number of GPS satellites are provided on six orbits around the earth at the altitude of about 20,000 km (four GPS satellites per one orbit),and move around the earth at 12-hour-gaps.
• Control segment (Ground control stations): Ground control stations perform the roles of checking, managing and supporting satellite orbit to make sure that the end of the satellites from the orbit,as well as GPS timing.
• User segment (GPS receivers): End-User Segment (GPS receivers).

Five Important Processes used in GPS:

1. Location     ==  Deciding a position.
2. Navigation  == Getting from one location to another location.
3. Tracking     ==  Keeping under observation on an object or personal activity.
4. Mapping     ==  Generating maps of the world.
5. Timing        ==  Making it possible to take accurate time measurements.

Accuracy of GPS Vehicle Tracking System?

The accuracy of a GPS Device is associated with many variables; The total number of satellites available,the ionosphere,and the urban environment. For example,accuracy leads to be above in open areas with no adjoining tall buildings,known as urban canyons. When a device is surrounded by tall buildings,the satellite signal is blocked by the buildings and then bounced off the building where it’s definitely read by the device. This could show miscalculations of the satellite distance.

Factors That Will Cause an Error in a GPS Device are:

• Signal appearance time measurements: Delays affected by physical obstructions like mountains, building, trees.
•  Atmospheric effects:  Ionospheric delays,heavy storm cover,and solar storms.
• Ephemeris: The orbital model within a satellite could be invalid or out of date, even though this is becoming less of an error.
• Numerical calculations: This might be a factor when the hardware isn’t designed with proper specifications.
• Artificial interference: GPS jamming devices or spoofs.
