Project:

GNSS Attitude, Positioning, and Profiling Experiment for the Enhanced Polar Outflow Probe Platform on the Canadian CASSIOPE Satellite

Location:

Canadian Space Agency, Ottawa, Ontario, Canada (2006-2008)

Purpose:

Position, velocity, attitude and time determination in real time

Configuration:

4 GNSS antennas mounted on the zenith-facing side of the spacecraft

Communications:

Bristol Aerospace STARS controller interface card

Details:

The four antennas used for clock functions, navigation and attitude determination, which together with their associated equipment is called GAP-A. GAP-A collects and processes simultaneous observations from three of the GPS receivers. The GAP-A real-time attitude determination system was developed using the GNT’s GNSS RTK engine.
