Abstract

The invention discloses a navigation device comprising a capture tracking processing module, a message extraction module, an observation quantity extraction module, a positioning calculation module and an output module. Continuous tracking of satellite signals is performed through the capture tracking processing module so that navigation telegraph bit data of a satellite are obtained. Satellite navigation telegraphs and observation quantity are acquired through the message extraction module and the observation quantity extraction module, and then positioning calculation is performed through the positioning calculation module and outputting is performed through the output module according to a binary format so that the navigation telegraph bit data of the satellite can be automatically and continuously acquired for positioning, the situation that navigation is not timely can be avoided, and thus the navigation device has the technical effects of timeliness and accuracy.

Description

technical field [0001] The present application relates to the technical field of satellite communication, in particular to a navigation device. Background technique [0002] With the continuous development of science and technology, satellite communication technology has also developed rapidly, and there are more and more types of electronic products, and people have also enjoyed various conveniences brought by the development of science and technology. Now people can enjoy the comfortable life brought by the development of science and technology through various types of electronic devices.
