Description:
A wireless localisation system that consists of a (possibly ad hoc or mesh) network of nodes has been build by the CSIRO ICT Centre. At present the system requires external surveying of its base stations to enable localisation of the mobile nodes. Some of our applications will use outdoor base stations, and it would be desirable to allow the base stations to determine their positions automatically using the GPS satellite signals. To obtain sufficient accuracy to replace the current surveying approach we need to use Differential GPS (DGPS).
The aim of this project is to implement a DGPS system using commercial GPS evaluation hardware, and custom programming to generate the DGPS correction signals in the RTCM 104 standard. The DGPS correction data will be distributed to the other base stations using the underlying network of wireless nodes. The final software will be in C/C++, but algorithm development may be done in MATLAB.
Possible extensions include the use of carrier based DGPS corrections for improved accuracy, and fusion of the DGPS information with the underlying localisation data.
The student undertaking this project should have:
• Basic understanding of GPS signals and operation
• Good programming skills in C/C++
• Experience using MATLAB
• Be able to work part of the time at the CSIRO site at Marsfield
