Abstract

The invention is applicable to the technical field of satellite navigation, and particularly relates to a satellite positioning device, a satellite signal receiver and a terminal device. The satellitepositioning device comprises a first satellite signal receiving module, a second satellite signal receiving module, a first antenna and a second antenna. The first satellite signal receiving module receives a first satellite signal with a first preset frequency and a second satellite signal with a second preset frequency through the first antenna. The second satellite signal receiving module receives a third satellite signal and a fourth satellite signal through a second antenna. Satellite signals are processed and positioned through different satellite signal receiving modules. The satellite-based correction information and the RTK correction information are respectively decoded based on different decoding units. According to the satellite positioning device, the data processing and positioning functions of the universal navigation chip can be fully utilized, the design process of a satellite signal receiver can be simplified, the implementation cost can be reduced, and high-precision positioning can be realized through the satellite positioning device formed by combining a plurality of universal navigation chip sets.

Description

technical field [0001] The application belongs to the technical field of satellite navigation, and in particular relates to a satellite positioning device, a satellite signal receiver and terminal equipment. Background technique [0002] With the development and improvement of satellite navigation systems, the role of satellite navigation systems in military and civilian markets is increasing. In satellite navigation and positioning, in order to realize satellite high-precision positioning algorithms such as real-time differential positioning (Real-time kinematic, RTK), precise point positioning (precise point positioning, PPP), dual-antenna orientation technology, the satellite signal receiver is required to be in the A huge amount of data can be processed in a very short time. Therefore, most of the current satellite signal receivers rely on high-performance navigation chips. However, due to the complicated design process of high-performance navigation chips, the cost of ...
