Abstract

The French Transportable Laser Ranging Station (FTLRS) is a highly mobile laser ranging station dedicated to geodetic and oceanographic satellite tracking. Its performances were estimated during a probatory experiment in Corsica (from October 1996 to February 1997). The results showed that the 1-sigma rms was close to 2 cm for 80% of the passes. But, about 20% of the passes exhibited significant variations in the signal quality (as much as 10 cm) and a large bias. The FTLRS has been considerably improved to reach the 1 cm accuracy. That is the level necessary for JASON-1 validation and calibration for which the FTLRS is a main component. The instrument evolutions concern all the FTLRS fundamental components: laser, detection devices, timing chain, and calibration process. Thanks to laboratory measurements and to some comparisons with the Grasse laser ranging fixed station with similar characteristics, the FTLRS new performances are satisfactory: the ranging accuracy may be of about 11 mm, with 9 mm due to the station. The first results of this new collocation experiment are presented.
