Orbit Determination of Lageos and Starlette and the Position Estimation of the European Laser Tracking Stations at Kootwijk, Wettzell, Grasse and Metsahovi

摘要

The positions of the European laser tracking stations were determined by separately processing LAGEOS and STARLETTE five-day and two-revolution data arcs. Range residual rms's and the recovered apparent range and timing biases of the five-day arc solutions are reported. Mutual differences between LAGEOS and STARLETTE solutions for station positions are given. Discrepancies between European, NASA, and Texas University baselines and solutions are discussed.
