Abstract

The invention relates to a magnetic bearing navigation digital integration system comprising a solid state three dimensional digital magnetic bearing sensing device, a GPS, an environment static magnetic field eliminator which form a directional sensing device and operation desk, a communication spreading apparatus, a communication adapter and a multiple display device which form a navigation centralized control equipment. The invention can overcome the problem of unstable reading as the result of the carrier swing of the dynamic magnetic rotor.

Description

Technical field [0001] The invention relates to a digital integrated system for magnetic orientation navigation, which is a digital integrated navigation system for carrier (vehicle) pointing and positioning. Background technique [0002] Currently, most of the pointing navigation devices used by vehicles are magnetic compasses or gyro compasses. The magnetic compass is safe and reliable. Its main disadvantage is that the installation environment is restricted, and the driver needs to perform complicated orientation conversion during use. It is inconvenient to combine with other navigation equipment, which restricts the integration and automation of navigation equipment. The gyro compass has a complex structure, high cost, requires a high-power power supply, has many failures, and has a short lifespan. Once the power supply fails or loses power, it cannot work. The GPS navigation equipment of the positioning category is generally popular, but it can only give the carrier position...
