Abstract

The invention provides an antenna array-based satellite navigation algorithm and system. The algorithm comprises the following steps: satellite signals output via an antenna array consisting of at least three antennas are obtained, a relative relation between all antenna positions is calculated according to the satellite signals, and position and state information of an object to be measured is calculated according to a position relation between the antennas on the object to be measured. Via the satellite navigation algorithm disclosed in the invention, three attitude angles can be obtained directly via antenna array technologies, and the algorithm has good application prospects.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a satellite navigation algorithm, a navigation system and a vehicle. Background technique [0002] Existing global navigation satellite systems (GNSS) include GPS, Beidou, GLONASS, Galileo, and some regional augmentation technologies or space-based augmentation technologies. The terrestrial receivers of these systems use either a single antenna or dual antennas. Among them, the system using a single antenna can be used for positioning, and the system using a dual antenna can be used for positioning and orientation. [0003] For example, the orientation function of existing GNSS equipment can only output the heading angle, but cannot support three attitude angles. In order to obtain the three attitude angles (heading angle, pitch angle, and roll angle) of the device, it is usually necessary to add other auxiliary means, such as a gyroscope. Contents of the invention [0004] In view...
