A system and method for determining the roll rate and roll angle of a spinning platform by using the measured phase and/or amplitude differences between the GPS satellite signals received on two or more antennas. The measured signal differences and the navigation solution from a GPS receiver are processed in a roll filter to obtain the desired information. Data from non-GPS measurement sources is optionally provided to update the navigation solution. Although of wide applicability, the invention is uniquely suited to the measurement of roll rates and rol...
1. A system for determining the roll rate and roll angle of a spinning platform comprising: a plurality of antennas for receiving GPS signals from at least one satellite, each antenna outputting an antenna signal for each received signal;a GPS receiver processor for forming the navigation solution; anda roll processor, for correlating each of the antenna signals separately, measuring the amplitude differences between the correlated signals from pairs of antennas, and processing the measured amplitude differences and navigation solution in a roll filter t...
