* Throughout the flight the GPS module in the payload box is providing information on its position, this information is passed through a microcontroller which reads the info and converts it into another protocol and in most payloads transmits the data over a radio link to the ground station. As a backup sometimes there is also a mobile phone which sends the data as a SMS as well (however this will only work near to the ground as mobile phones don't get signal at high altitudes). | * Throughout the flight the GPS module in the payload box is providing information on its position, this information is passed through a microcontroller which reads the info and converts it into another protocol and in most payloads transmits the data over a radio link to the ground station.

* While this is all good when the payload is in the air when it nears the ground the range reduces as we lose LOS and the range is similar to what is quoted. It is therefore important to either have a GSM communication system that sends you a SMS with the final location or chase the payload so that you are close by when it lands. | * While this is all good when the payload is in the air when it nears the ground the range reduces as we lose LOS and the range is similar to what is quoted.
