Problems solved by technology

The inventors have found that satellite navigation equipment or satellite positioning equipment are usually powered by batteries, which is conducive to more convenient installation on vehicles and work independently, but the battery power often cannot meet the demand, for example, the working time of a rechargeable battery after one charge is relatively short. Short or insufficient battery life will inevitably hinder the continuous

Abstract

The invention provides a device and method for reducing the power consumption of satellite positioning equipment through an inertia measurement unit. A satellite positioning unit can be switched between a low-power-consumption standby mode and a normal power consumption operation mode by arranging a work mode control unit, the precision of satellite navigation positioning results can be easily ensured, the power consumption of the satellite positioning equipment can also be reduced, and the use effect of the battery electric quantity is improved. The device comprises a main control unit in thesatellite positioning equipment and the satellite positioning unit, and is characterized in that the inertia measurement unit is arranged in the satellite positioning equipment, the inertia measurement unit is connected with the main control unit, and the main control unit is connected with the satellite positioning unit through the work mode control unit.

Description

technical field [0001] The present invention relates to satellite navigation technology, especially a device and method for reducing the power consumption of satellite positioning equipment by using an inertial measurement unit. By setting the working mode control unit, the satellite positioning unit can operate in a low-power standby mode and a normal power consumption mode. Switching between them is beneficial to not only ensuring the accuracy of satellite navigation and positioning results, but also reducing the power consumption of satellite positioning equipment and improving the efficiency of battery power usage. Background technique [0002] With the wide application of the global satellite navigation system and the improvement of Beidou enhanced high-precision satellite navigation services, the performance of satellite navigation equipment is getting higher and higher, and navigation equipment capable of differential enhanced high-precision positioning is gradually us...
