Abstract

The invention discloses a long and short term memory network assistance-based satellite positioning method. The method comprises a conventional algorithm engine, a neural network algorithm engine anda usable flag bit of the neural network algorithm engine. The method is characterized in that the conventional algorithm engine is adopted to give a satellite positioning result under a condition thata satellite is favorable in signal, and the satellite positioning result is utilized to train and test a neural network. When a receiver is located under a complicated condition, if the neural network algorithm engine is trained and can be used, the neural network algorithm engine is used for predicting the positioning result. The method is capable of utilizing the trained neural network to predict the coordinate of the receiver when the performance of the conventional algorithm engine is greatly reduced, so as to improve the satellite positioning success rate.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a satellite positioning method assisted by a long-short-term memory network. Background technique [0002] GNSS (global navigation satellite system) is a general term for a class of navigation systems that use in-orbit satellites to transmit radio signals for passive ranging and positioning. GNSS is a self-positioning system, that is, the positioning solution is calculated in the navigation device, and the calculated positioning position result does not need to transmit any signal. [0003] In the 1960s, the United States established the world's first satellite navigation system, the Meridian satellite navigation system, which was mainly used for ship navigation and operated until 1996. Then Russia also established a similar system - San Kada satellite navigation system. In 1978, the first operational satellite of the US Global Positioning System (GPS) was succes...
