Embodiment Construction
[0027] As we all know, the satellite navigation data calculation unit directly determines the accuracy and calculation speed of the navigation results, and occupies a considerable part of the power consumption of the satellite navigation module. Since the navigation data calculation only needs the navigation message and clock information when the calculation is started ( A frame of navigation message is about 1000bit), and other information is no longer needed in the calculation process; and, with the development of mobile communication technology, wifi, 3G and even 4G technology mature, the power required for data transmission is getting smaller and smaller (according to It is estimated that an ordinary smart TD mobile phone equipped with a 1400mAH battery can easily transmit more than 5Gbit of data with only half the power, which is equivalent to transmitting hundreds of thousands of navigation message data). Therefore, the present invention provides a satellite navigation sy...

The invention discloses a satellite navigation system and an implementation method. The implementation method comprises the following steps that: a terminal receives navigation telegraph text data from an orbit satellite; the terminal selects a corresponding navigation data resolving platform to resolve the navigation telegraph text data to obtain a navigation result according to a plurality of performance indexes, wherein the plurality of performance indexes include network connectivity, power consumption, resolving speed and resolving accuracy, and the navigation data resolving platform is at least one of a terminal navigation data resolving platform and a cloud navigation data resolving platform; and the navigation data resolving platform sends the navigation result to the terminal. According to the invention, the terminal selects the corresponding navigation data resolving platform according to the performance indexes of the terminal and the resolving requirement indexes, and the satellite navigation data resolving part can be transferred to and implemented on the cloud navigation data resolving platform, so that the requirements on power consumption of a satellite receiving unit on the terminal are reduced and the navigation data resolving speed and accuracy are improved.
Description
technical field [0001] The invention relates to satellite navigation technology, in particular to a satellite navigation system and a realization method. Background technique [0002] With the development of information technology, satellite navigation technologies, such as GPS and Beidou, have become widely used in mobile terminals. Some experts predict that the global satellite navigation industry can reach about 500 billion U.S. dollars. By 2020, the localization rate of ground equipment in my country's navigation industry will reach 80%, and the Beidou market will rise to about 100 billion U.S. dollars. [0003] Such as figure 1 As shown, a typical Beidou satellite navigation message receiving module generally includes three parts: antenna 1, baseband signal processing unit 2, navigation data computing unit 3 and interface 4. The baseband signal processing unit 2 receives the necessary navigation message data from the orbiting satellite through the antenna 1, and then ...
