Mission Objectives:
Initially, LRE (Laser Ranging Equipment) was used to evaluate the accuracy of the initial trajectory determination of the H2A 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.
Mission Instrumentation:
The instruments on-board LRE are:
- Retroreflector array
- Plate mirrors
