Abstract
A system for attitude determination of a platform in global positioning systems (GPS) is disclosed herein. The system includes at least two receivers and an attitude determination circuit. The receivers each include an antenna. The antenna is capable of receiving GPS signals. Each receiver also produces a representation of the received GPS signal by estimating how fast the distance from a GPS satellite to the antenna is changing by determining a rate of change of a locally generated code sequence as it changes to approximate the GPS signal transmitted by the GPS satellite. The attitude determination circuit calculates platform attitude from the rate of change determined by the receivers.
