Low-cost autonomous navigation device and navigation method for communication-assisted positioning

Abstract

The invention provides a low-cost autonomous navigation device and a navigation method for communication assisted positioning. The low-cost autonomous navigation device comprises mobile autonomous navigation equipment and ground communication base station equipment. The mobile autonomous navigation equipment comprises an autonomous navigation module, a communication auxiliary positioning module and a power supply module, and the autonomous navigation module comprises a gyroscope, an accelerometer, a magnetometer, a barometric altimeter, a microprocessor and a peripheral circuit; the communication auxiliary positioning module comprises a signal encoder, a power amplifier, a signal demodulator, a signal synchronization and timer, a radio station antenna and a communication serial port. The mobile autonomous navigation equipment is powered on before the carrier is launched, receives binding data of the ground communication base station device, and completes functions of multi-sensor dataacquisition, communication auxiliary positioning information calculation, multi-source information fusion filtering navigation and the like after the carrier is launched. The mobile autonomous navigation equipment adopts a low-cost and light design method, and can adapt to autonomous navigation and precise guidance combat tasks under the condition of satellite navigation signal loss in a modern war environment.

Description

technical field [0001] The invention belongs to the technical field of navigation, guidance and control, and relates to a low-cost autonomous navigation device and a navigation method for communication-assisted positioning. Background technique [0002] The guidance and control of mobile carriers such as UAVs, guided munitions, unmanned ships, and unmanned vehicles rely heavily on accurate positioning, orientation and navigation information. This is a realistic and complex interference problem, and it is difficult to ensure the accurate positioning of the movable carrier during the whole movement. Traditional radio navigation technology can replace satellite navigation to a certain extent and play an important role in the positioning and navigation of large aircraft and ships. Small manned or unmanned movable carrier. [0003] In view of the above problems, it is urgent to develop a low-cost autonomous navigation device and navigation method for communication-assisted posi...
