Multi-Pseudolite Experiment at SNAP

 

During the period from mid-December 2000 to 6 January 2001, two sets of IntegriNautics IN200CXL pseudolites were loaned to SNAP by Prof. Elizabeth Cannon (Dept. of Geomatics Engineering, University of Calgary, Canada) for experiments. Together with the pseudolite owned by SNAP, the three pseudolites were used for tests to study a variety of GPS+pseudolite scenarios.

 

Several experiments were conducted, e.g. the three pseudolites transmitted GPS-like signals from locations around the Cricket Ground, as well as from a balloon (see below). A total of six NovAtel receivers were operating on the ground simultaneously making GPS and pseudolite measurements. A second experiment was conducted on 3 January 2001 at the BHP Port Kembla Flat Steel Products plant.
