Abstract:	This paper describes the testing and adaptation of a commercial GPS receiver for applications on small satellites. To operate in space, a number of factors must be considered relating to the environment, including software design, interfaces, thermal, vacuum, vibration, and perhaps most significantly, radiation dosage. A commercial GPS receiver has been taken (the Sigtec MG5001) and adapted for space applications. The whole board was tested for total ionising dose radiation tolerance, and the core processor/correlator, the Zarlink GP4020 was specifically evaluated for susceptibility to Single Event Upsets.
