Embodiment Construction

[0027] The embodiments of the present invention will be described below in conjunction with the drawings.

[0028] The embodiment of the present invention provides a satellite timing method, such as figure 1 As shown, including the following steps:

[0029] Step s101, receiving the first group of navigation message signals sent by the first group of satellites and the second group of navigation message signals sent by the second group of satellites;

[0030] Step s102, parse the first set of navigation message signals to obtain a first set of timing signals, and analyze the second set of navigation message signals to obtain a second set of timing signals;

[0031] Step s103, fusing the first set of timing signals and the second set of timing signals;

[0032] Step s104: Convert the fused timing signal into a differential level signal and send it to the base station.

[0033] By adopting the method provided by the embodiments of the present invention, the dual-mode satellite timing receiv...

Abstract

The embodiment of the invention discloses a method, a device and a system for satellite time service. The method includes the steps as follows: receive the first set of navigation message signals transmitted by a first group of satellites and the second set of navigation message signals transmitted by a second group of satellites; analyze the first set of navigation message signals to gain the first set of timing signals and analyze the second set of navigation message signals to gain the second set of timing signals; combine the first set of timing signals with the second set of timing signals; transform the combined timing signals into differential level signals and transmit the differential level signals to a base station. The embodiment of the invention uses a double-mode satellite time service receiver to receive the signal transmitted by the two groups of satellites and to accurately position the double-mode satellite time service receiver, combines the two set of timing signals and realizes precise and reliable time service.

Description

Technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular to a method, device and system for satellite timing. Background technique [0002] In the communications field, good network synchronization performance has a significant impact on telecommunication services. Poor synchronization often brings a series of problems. In wireless networks, synchronization problems are particularly important, such as poor voice quality, high call drop rate, low handover success rate, and inaccessibility, and many other problems are synchronized with the network to a large extent. Poor performance is related. CDMA (Code Division Multiple Access, Code Division Multiple Access) / TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) / WIMAX (Worldwide Interoperability for Microwave Access) and other wireless standards In base station equipment, accurate time synchronization between base stations is required. At present, bot...
