Abstract

The invention is suitable for the technical field of positioning and orientation, and provides a satellite orientation device which comprises a satellite orientation chip and a satellite positioning chip connected with the satellite orientation chip. The satellite orientation chip is used for determining first integer ambiguity and position information of a target vector based on the first pseudo-range observed quantity, the first carrier phase observed quantity, the second pseudo-range observed quantity, the second carrier phase observed quantity, the first positioning information and the second positioning information from the satellite positioning chip as well as the determined third pseudo-range observed quantity, third carrier phase observed quantity and third positioning information of the satellite orientation chip relative to the first satellite and a preset observation equation; the accuracy of the position information is determined based on the first integer ambiguity and the preset integer ambiguity, and the direction information of the target vector is determined based on the position information when the accuracy meets the preset requirement, so that the cost and the power consumption of the satellite orientation device are reduced, and the orientation accuracy is improved.

Description

technical field [0001] The application belongs to the technical field of positioning and orientation, and in particular relates to a satellite orientation device. Background technique [0002] With the continuous development of satellite positioning and orientation technology, the application of satellite orientation devices capable of realizing satellite orientation functions is becoming more and more extensive. Existing satellite orientation devices usually include two satellite positioning chips and a processor. The two satellite positioning chips usually receive satellite signals at the same frequency point, and output positioning information and observation data after processing the received satellite signals respectively. To the processor, the processor performs orientation calculation based on the positioning information and observations output by the two satellite positioning chips respectively, that is, the existing satellite positioning chip does not have the orien...
