Abstract:	This paper concerns the method of GPS attitude determination (GPS-AD) based on carrier phase measurements. Integrity and Receiver Autonomous Integrity Monitoring (RAIM) are presented. The paper remodels a new ADOP scheme based on two reasons. The relations between ADOP and the baseline length, attitude, elevation angle of satellite are analysis. Based on the analyzed, a set of health SVs can be selected to optimize the outcome of GPS-AD system. The corresponding flow chart and steps are given. By forming linear combinations (difference) of similar measurements from two receivers, satellites, epochs or frequencies, four categories single difference (SD) are expounded in this paper. Difference RAIM (DRAIM) is proposed. Two types DRAIM (Which separately from delta SD-1S2A and delta SD-2S1A) are deduced comprehensively in GPS-AD, They are used to detect and exclude the fault caused by multipath and static structural distortion in theory.
