Problems solved by technology

However, the cost of high-precision POS is high, even much higher than the cost of developing a stable platform itself, and the data input / output delay of a specific type of POS is fixed, which cannot simulate the data delay of the actual system
In addition, when the oscillating table is installed in a room or basement where it is inconvenient to receive satellite signals, POS will not be able to correct gyro drift (especially heading drift)

Description

technical field [0001] The invention belongs to the field of test and measurement, and relates to a simulated POS system for stable platform testing, in particular to a configurable simulated position and attitude measurement system (position and attitude measurement system) and a method for stable platform testing. Background technique [0002] With the gyro as the sensitive element, the electromechanical control system that can isolate the angular motion of the moving base carrier and make the controlled object rotate according to the command is called the gyro-stabilized platform, referred to as the stable platform. The stable platform has two basic functions: one is the stabilization function, that is, it can counteract the external angular disturbance; the other is the tracking function, that is, it can rotate at the angular speed required by the command. The stable platform and the load equipment on it, the moving base carrier (aircraft, ship, rocket, satellite, etc.) ...
