Impact on CCR's machining error on laser range finder of satellites

Abstract

The impacts of angle error distribution of satellites corner cube reflector (CCR) on laser energy distribution on ground are introduced. The error of CCR is designed for the velocity-difference according to the altitude of satellites, but the actual machining error is affected by manufacture. Statistics of lots of CCRs for Galileo indicate that: the average valve of different batches of CCR's angle errors is 0.775"-0.894" relative to the designed valve 0.8"±0.5". The σ of different batches is 0.278"-0.309". The results of computer simulation and actual measure indicate that: These batches of CCRs match the criterions and requests.
