Abstract
An approach to global positioning system (GPS) attitude determination and the results of an experimental evaluation are presented. The most outstanding features of the method are the fundamental observable used for attitude calculation, the triple difference, and the introduction of a new parameter, the differential dilution of precision (DDOP), which relates the GPS satellite geometry to the GPS accuracy when measuring angular magnitudes. The experiment used two commercial off-the-shelf GPS C/A code receivers delivering integrated Doppler measurements. The algorithm is robust with respect to phase cycle slips and does not require solving the usual integer ambiguity of the measurements. The preliminary results show that absolute attitude determination requires a calibration of the baseline and that the relative attitude accuracy is on the order of 0.1 degrees or 2 mrads for the case of a 2-m-long baseline.Keywords
