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.
