Problems solved by technology

[0017] see figure 1 , each time a capture operation is performed, one of the navigation systems will completely occupy the existing hardware resources; assuming that the hardware resources include 32 hardware channels (which can capture up to 32 satellites at the same time), using the above scheme, even if the current system only has 1 satellites to be captured, the remaining 31 hardware channels cannot be used for other navigation systems; in summary, the current navigation receiver cannot make full use of hardware resources when capturing, resulting in a long system start-up time

Abstract

The invention discloses a method for realizing capture processing and a receiver. The method comprises the following steps: setting a first to-be-captured satellite list according to to-be-captured satellites of all navigation systems; executing a first capture integral operation of a first preset duration on the first to-be-captured satellite list; and determining a capturing sequence for capturing the to-be-captured satellites according to a result of the first capturing integral operation. According to the embodiment of the invention, the hardware resource utilization rate of the navigation receiver is improved, and the starting time of the navigation system is reduced.

Description

technical field [0001] This article involves but is not limited to satellite navigation technology, especially a method and receiver for realizing acquisition processing. Background technique [0002] Global Navigation Satellite System (GNSS, Global Navigation Satellite System) is playing an increasingly irreplaceable role in people's daily life, especially in the fields of navigation, exploration, monitoring, measurement, communication timing, etc. . With the rapid development of civilian applications in recent years, the global satellite navigation system has gradually deepened in daily life. From mobile phones, personal computers, automobiles, civil aircraft to missiles and fighters, satellite navigation technology is inseparable. All major countries in the world are striving to develop satellite navigation technology. Currently, there are multiple satellite navigation systems. Countries compete independently to develop satellite navigation technology and mutually compat...
