Abstract

The invention discloses a mooring airship attitude measurement device and method. The mooring airship attitude measurement device comprises a laser gyroscope strapdown inertial navigation module, a navigation processing module and a GPS (global positioning system) positioning and orientating module, wherein the navigation processing module comprises an FPGA (field programmable gate array) and a DSP (digital signal processor) which are connected bidirectionally; and the FPGA is connected with the laser gyroscope strapdown inertial navigation module, the GPS positioning and orientating module and a mooring airship control system. The measurement device disclosed by the invention is simple in structure, is high in accuracy, is low in power consumption, is good in environment adaptability, and is high in reliability; through synchronously collecting the orientation and speed information of the GPS positioning and orientation module, the difference value between the orientation and speed information of a GPS and the orientation and speed information of navigation resolution acts as the input of a Kalman filter; and the error of inertial navigation is estimated in real time, and meanwhile is fed back and rectified, and the long-time accuracy maintaining of navigation information is realized.

Description

technical field

[0001] The invention relates to the fields of combined navigation and guidance, and attitude measurement and control, in particular to a tethered airship attitude measurement device and a measurement method. Background technique

[0002] The tethered boat floats in the air for a long time to work after it is launched, and it is necessary to obtain high-precision attitude information of the tethered boat in real time for attitude control of the tethered boat. Therefore, it is necessary to develop an attitude measurement device for high-precision measurement of the attitude and other information of the moored boat.

[0003] Currently, strapdown inertial navigation systems or multi-antenna GPS attitude measurement systems are usually used on moored boats. Strapdown inertial navigation does not rely on any external information, and can measure the true north heading, pitch and roll of the carrier. However, during the initial alignment period, the carrier is requ...
