Simulation of the Global Geodetic Observing System

The overall objectives of GGOS-SIM is to create a tool to simulate the complete current ground network of the most important space geodetic techniques: GNSS, VLBI, SLR, and DORIS, the effects of the various ongoing and planned technical developments of these observing techniques on the International Terrestrial Reference Frame (ITRF), the impact of local ties, their required accuracy and monitoring intervals, and the impact of new collocation sites on the existing observing system. As a main result GGOS-SIM will offer the ultimate tool for testing and improving the current and future realizations of the International Terrestrial Reference System (ITRS). Consequently, the simulations to be carried out within GGOS-SIM will help planning and coordinating an efficient development of the international geodetic infrastructure as backbone of the Global Geodetic Observing System (GGOS).

Information on the project can be found on the project homepage at TU Berlin.
