Initially, LRE (Laser Ranging Equipment) was used to evaluate the accuracy of the
initial trajectory determination of the H-2A-202 launch vehicle. Subsequently, the satellite
was used to verify SLR station performance, as a target for wide dynamic range of
transmitting/receiving tests up to geosynchronous orbit for optical communication and SLR,
and to evaluate the air drag model using SLR data.
Retroreflector Array Characteristics:
The array consists of 126 cube corners and 24 plate mirrors. There are two kinds of cube
corners (fused silica and BK7). Approximate center of mass correction is 210 mm.
