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.
