The short-arc approach to laser ranging analysisnation of the coordinates of ground stations and their temporal variations. The method makes use of very short orbital arcs (lasting less than two hours for LAGEOS) observed almost simultaneously by at least three stations and is particularly addressed to the solution of “local” networks (of contine

The short-arc approach to laser ranging analysisnation of station positions even with a simplified dynamics, as it is shown by a test campaign involving six European stations for a duration of seven years. We propose a modification of the method which should reduce its sensitivity to large systematic errors in the observations and improve the stochastic model.
