Abstract

The invention belongs to the technical field of location and navigation, and discloses a mobile offshore platform location and navigation method based on a lightning location network. The mobile offshore platform location and navigation method based on the lightning location network utilizes the lightning detection information of the long baseline lightning location network, and the mobile offshore platform detects the corresponding low frequency lightning signal; and through the time difference of arrival, the time variation information of the geographic coordinates of the platform can be obtained on the premise that the spatial position of the mobile platform is continuously changed. The mobile offshore platform location and navigation method based on a lightning location network utilizes the external field observation experiment conducted by the world wide lightning location network (WWLLN) to show that the mobile platform location technology based on the long baseline lightning location network is feasible. The location and navigation technology based on the lightning location network is not only suitable for the mobile offshore platform, but also has certain effect on locationof a remote area or an area with earth covering.

Description

technical field [0001] The invention belongs to the technical field of positioning and navigation, and in particular relates to a positioning and navigation method for a mobile offshore platform based on a lightning positioning network. Background technique [0002] At present, there are multiple sets of Roland-C station chains working normally around the world. Among them, China's Changhe-2 system has a total of six launch stations and three system work area monitoring stations. Because the signal coverage area of ​​the Roland-C system can be as deep as hundreds of meters underwater, a similar system is Roland-A (currently still used in some countries and regions, but the main users have changed to Roland-A with superior performance. C system) and Roland-D (the U.S. military tactical mobile medium-range navigation and positioning system, which also provides high-precision navigation and positioning implementation services for offshore oil development), etc. The above metho...
