SLR and GNSS co-location and delay control for the application of laser time transfer

Popis výsledku v původním jazyce

Recent progress in the optical time transfer using SLR stations is increasing the demands for the stability and accuracy of the local ties measurement of the stations. The main aim of projects like the European Laser Timing (ELT) is the time synchronization with a precision of better than 40 ps rms and an absolute error well below 100 ps. Synchronization in time requires a good control over all system delays involved in the measurement process. We have put a lot of effort in improving the Wettzell LaserRanging System (WLRS) to cover these requirements. Furthermore we have developed a two-way measurement technique allowing the collocation of the GNSS receivers at Geodetic Observatory Wettzell with respect to time . We are continuously working on improving the additional external target calibration techniques with the goal of including the external target measurements daily and automatically. Our next activity is focused in development of the new GNSS station, which is connected to the
