Integrated navigation installation device and method

Abstract

The invention relates to the field of navigation, and discloses an integrated navigation installation device which comprises an integrated navigation system and an integrated sensor. The integrated navigation system comprises a system base and a system shell. The top of the system base is provided with a gyroscope, an accelerometer and a navigation circuit. The system shell surrounds the gyroscope, the accelerometer and the navigation circuit, the top of the system shell is provided with an integrated sensor, and the integrated sensor is connected with the navigation circuit through an electrical interface. According to the integrated navigation installation device, the integrated navigation system and the integrated sensor can be installed at the same time without a special installation base, installation errors are obviously reduced, and the size and cost are reduced.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a combined navigation installation device and a method for installing the combined navigation installation device. Background technique [0002] Combined navigation is a navigation system that combines two or more than two navigation devices on the carrying object. Combining several different single navigation systems can use a variety of information sources to complement each other and form a multi-channel system. Dimensional and multi-directional integrated navigation system. [0003] The existing integrated navigation system usually takes the inertial navigation system as the core, and combines different sensors and navigation models to realize integrated navigation. In many integrated navigation systems, some sensors (measurement cameras, sensors, total stations, satellite navigation receiver antennas, etc.) need to be fixedly connected to the integrated navigation system. Among t...

Problems solved by technology

[0004] This scheme of the prior art has the following disadvantages: (1) the existing scheme installs the integrated navigation system and the sensor on the special mounting base respectively, and needs a larger mounting base than the special mounting base of the integrated navigation system, which increases The installation volume, weight, difficulty and cost are affected; (2) The integrated navigation system has space occlusion for the sensor, which affects the normal operation of satellite navigation and optical sensors within a certain range, and affects the accuracy of integrated navigation; (3) In order to avoid installation position errors and installation angle error, the existing technology usually adopts a suitable calibration method for calibration, and inputs the calibrated installation error in the integrated navigation solution, but due to temperature changes and changes in the force state, the installation error will change, resulting in combination The navigation error is relatively large; (4) Even if a special repeated installation structure is used to improve the repeated installation accuracy of the integrated navigation system and the sensor, the error change after repeated installation can be up to twice the error of a single device repeated installation, making repeated installation (5) Since both the integrated navigation system and the sensor require a special repeated installation structure, there are many installation links, and repeated installation is inconvenient
