Abstract

The invention relates to the field of satellite navigation, and discloses a satellite navigation signal acquisition and playback method based on a mobile intelligent terminal. The method comprises thefollowing steps of: performing powering on, and establishing communication connection between a satellite navigation signal acquisition and playback instrument and the mobile intelligent terminal; periodically sending heartbeat by the satellite navigation signal acquisition playback instrument, and when the sent heartbeat is not responded, conducting disconnection; and receiving an operation instruction of the mobile intelligent terminal, and carrying out corresponding operation by the satellite navigation signal acquisition playback instrument. The invention further provides a satellite navigation signal acquisition and playback system based on the mobile intelligent terminal, and the satellite navigation signal acquisition and playback system comprises the mobile intelligent terminal and the satellite navigation signal acquisition and playback instrument which are in communication connection, and the satellite navigation signal acquisition and playback instrument comprises a radio frequency unit, a storage unit and a communication module which are connected with a processing unit. According to the invention, visual management, monitoring and operation of satellite navigation signal acquisition, storage and playback by a user are greatly facilitated, remote monitoring and upgrading maintenance are also facilitated, and test, research and development of the navigation terminalare facilitated.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a method and system for collecting and playing back satellite navigation signals based on a mobile intelligent terminal. Background technique [0002] Since the actual performance of the navigation terminal is closely related to the application scenario environment, relying solely on the signal simulator for laboratory testing can no longer meet the R&D and production needs of satellite navigation products. Therefore, more and more attention is paid to the acquisition and playback test based on real satellite navigation signals. The method can record the signal state under different geographical, electromagnetic, carrier and other environments, truly reflect the actual performance of the terminal under test, and facilitate the technical research and product testing of navigation R&D and production enterprises. [0003] At present, domestic satellite signal acquisition and play...
