Abstract

The embodiment of the invention provides a position tracking method and a device applied to a portable station. Through a pre-tracking model, an antenna position is judged and a satellite theoretical position is solved; a coarse tracking module carries out tracking in a dot matrix mode for searching for sampling points whose satellite beacon level values are larger than a tracking threshold; and a fine tracking module carries out tracking in a cross dot matrix mode for searching for the maximal satellite beacon level point. By adopting the method and the device provided by the embodiment of the invention, an open loop control method is adopted, in comparison with a closed loop control method, elements such as a position feedback element and an encoder can be saved, the space of the portable device can be saved, and the weight of the portable device is reduced. As the elements in the portable station are reduced, reliability of the portable station is enhanced, maintenance is easy, and stability is high.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically relates to a location tracking method and device applied to a portable station. Background technique [0002] The portable station is a set of portable equipment that communicates with the satellite. It can download data from the satellite and upload data to the satellite. Its main function is to provide two-way broadband transmission channel, and provide comprehensive services such as high-quality voice, data and real-time images. [0003] The lighter the weight of the portable device, the smaller the volume, the better. However, the portable device in the prior art is larger in size and heavier in weight. The inventor found in the process of realizing the invention that the portable station uses a tracking algorithm to track the position of the satellite signal, and Closed-loop control is used to improve the accuracy of the position of the portable station t...
