GPS

The Global Positioning System (GPS) is a satellite-based navigation system used to determine the exact latitude, longitude and altitude of a point. The main objectives of the GPS Payload in the Jugnu nano-satellite are as follows:

• Time Synchronization: From time to time the OBC will retrieve time data from the GPS module, and will correct it's time.
• Providing Orbital Parameters from GPS data to the ADCS system. A periodic position data obtained from the receiver will assist in correction of satellite position error accumulated in orbital model with time.
• Custom made algorithm to be programmed into the ARM7 based processor which allows for corrections and improvements to be made according to our requirements. This will also help in testing of newly developed correction algorithms.
