Abstract
A positioning module is disclosed. Positioning module includes a satellite selection module and a filter. The satellite selection module is configured for selecting one or more positioning satellites among a plurality of satellites of one or more satellite navigation systems and outputting satellite information of the one or more positioning satellites. Filter coupled to the satellite selection module is configured for receiving the satellite information of the one or more positioning satellites, and calculating a position information of positioning module.
Claims23
A positioning module comprising:
- a satellite selection module, configured for selecting one or more positioning satellites among a plurality of satellites of one or more satellite navigation systems and outputting satellite information of the one or more positioning satellites;
- and
- a filter coupled to the satellite selection module, configured for receiving the satellite information of the one or more positioning satellites, and calculating a position information of positioning module.
A positioning device, comprising:
- a radio frequency (RF) module, configured for mixing frequencies of a plurality of received satellite signals with a frequency of a signal generated by positioning device to generate a plurality of intermediate frequency (IF) signals, wherein the plurality of received satellite signals are transmitted by one or more satellites of one or more satellite navigation systems;
- a baseband signal processing module, configured for processing the plurality of IF signals, calculating a satellite information of the one or more satellites, and classifying the plurality of received satellite signals;
- and
- a positioning module coupled to the baseband signal processing module, configured for selecting one or more positioning satellites from the one or more satellites according to a classification of the plurality of received satellite signals, and calculating a position information of positioning device.
A positioning method for a positioning device, comprising:
- receiving a plurality of satellite signals, wherein the plurality of satellite signals are transmitted by one or more satellites of one or more satellite navigation systems;
- calculating, by capturing and tracking the satellite signals, a satellite information of the one or more satellites and classifying the plurality of satellite signals;
- selecting one or more positioning satellites from the one or more satellites according to a classification of the plurality of satellite signals;
- and
- calculating a position information of positioning device.
