NASA/GSFC intends to procure satellite laser ranging (SLR) services from the University of Hawaii. This sole source contract will cover the operations, maintenance, and calibration of the NASA Transportable Laser Ranging System (TLRS-4). Additionally, the contractor will support the planning, installation, and operation of new NASA geodetic stations as part of the NASA Space Geodesy Network (NSGN).
