Twodimensional reference largefield transfer method by linear CCD

To realize locating and heading determination fast, a twodimensional referrence transfer system was proposed which can achieve realtime transferring of heading determination information for Beidou satellite navigation system (BDS) by linear charge coupled device (CCD).This system consists of the BDS heading determination aerials,the light source part, the optical measuring part and so on. It can realize 2D measurement rapidly and accurately by using the N shape light source and linear CCD splicing technology. A precision testing experiment was designed based on the 2D reference transfer system. The test results shows that on the condition of 8m measuring distance, the measuring range is 1.5, and the measuring accuracy is no more than 5. This system provides an effective technical solution for 2D determination heading reference widefield transferring.
