Abstract

The embodiment of the invention discloses a course angle determination method and system, an electronic device and a storage medium. The method comprises the following steps: acquiring longitude and latitude data at the current moment through one path of signal, and determining current coordinate data based on the Mercator coordinate transformation model and the longitude and latitude data, obtaining a historical coordinate data set corresponding to the historical moment set, determining a first course angle and a second course angle according to the current coordinate data and the historicalcoordinate data set, and determining a target course angle according to the first course angle and the second course angle. Based on the embodiment, longitude and latitude data of the carrier at the current moment are obtained through one path of signal transmitted to the satellite receiver by one satellite antenna, the target course angle is determined by combining the historical coordinate dataset corresponding to the historical moment set, so that the course angle error caused by slight jitter when the carrier performs linear motion can be reduced, the real-time precision of the course angle is improved, and the problem of introducing an installation angle error can be avoided.

Description

technical field [0001] The present invention relates to the technical field of navigation and positioning, in particular to a method, system, electronic equipment and storage medium for determining a heading angle. Background technique [0002] Navigation and positioning is an important technology used in the fields of autonomous driving, drones and autonomous robots. At present, outdoor navigation and positioning are mostly based on global positioning system or Beidou satellite positioning system to receive positioning data, but positioning data cannot be received indoors and in some shielded places. Moreover, the update frequency of the satellite positioning data is generally 1-10 Hz, which cannot meet the requirement of the client that the update frequency of the positioning data is 100 Hz or above. [0003] Inertial navigation technology is a common navigation and positioning technology. The inertial measurement unit is used to measure the three-axis acceleration and th...
