Project Description

We recently built an FPGA GPS receiver which has been incorporated into a satellite and is due to be launched later in the year.

This receiver sends back raw GPS signal measurements from which it should be possible to determine the position of the satellite as well as properties of the atmosphere based on the signal delays. We have a second copy of the GPS that is almost identical to the one in the satellite and can be used for experimentation.

The main aims of this project are to use the raw GPS measurements obtained from the GPS receiver module (codephase and carrier phase) to determine the position of the GPS receiver and the delay of the GPS signals through the atmosphere. Initially we will be using the measurements from the duplicate receiver on earth. But hopefully we will be able to use the data from the actual satellite early next year.
