Abstract
A space vehicle uses a signal received from a global positioning system (GPS) satellite (51, FIG. 1) to determine the attitude of a space vehicle. The signal is received through a pair of antennas (10, 11) and converted to sum and difference outputs by a sum and difference circuit (30). These outputs are then conveyed to down converter/correlators (55), and then to envelope detectors (60). The outputs of the envelope detectors (60) are then converted to a digital format by an analog to digital converter (70). The digitally formatted sum and difference amplitudes are then used by a processor (80) to calculate the required attitude adjustment to the space vehicle.
