Mission Objectives:

The US Air Force Research Laboratory (AFRL) has flown a hollow retroreflector on the STPSat-2 mission. It is a commercial item that is lightweight and allows for testing at any laser wavelength. AFRL will post temperature data for the cube and provide satellite orientation. Temperature effects on the cross-section and angular (off-axis) performance will be documented and participating SLR sites will be acknowledged.

The SLR role of the mission is to gather data on changes in optical cross section over a period of 4 months. Monitor passes ( >45 degree elevation angle). The cube temperature will be recorded during the experiments as well as satellite orientation to assist in the off-axis analysis. The data will be used to determine the utility of this device to provide AFRL with an inexpensive means for carrying out tracking of small satellites.
