The results from a 13.8 km horizontal laser communication (lasercom) link between the Space Technology Research Vehicle 2 (STRV-2) ground terminals are presented. These terrestrial tests are a precursor to the STRV-2 satellite-to-ground lasercom experiment scheduled to commence shortly after launch in June of 1999. Testing ground terminal performance through long terrestrial horizontal ranges (greater than 10 km) mimics the atmospheric effects of an uplink slant path to the low earth orbit (LEO) satellite. Bit error rates averaging 10-6 to 10-7 were achieved with only one of the three transmit telescopes operating. The terrestrial path also passed very close to a ridge, which most likely added additional ground scintillation. We expect much improved link performance once all three transmit telescopes are operational. These long-range horizontal tests will assist in the development of a long-range commercial terrestrial lasercom product, which will be baselined on the ground terminal design.
