GPS Measurements (2003-2006) in the Sikhote Alin Network, the Far East

This paper considers results of geodynamic studies using the GPS method in the territory of the Far East. GPS measurements using TRIMBLE-4700 geophones were launched along the Sikhote Alin profile in 2003. The technology of the GPS measurements and the problems of selecting the measurement sites and network configuration with reference to the region's structure are discussed. The results of GPS measurements in 2003-2006 were used to study the fault system of the Far East continental margin. Different models of the Eurasia rotation (from the known NNR-NUVEL-1A to the recent ones) were analyzed. The solid-body rotation of Eurasia was predicted in the framework of the AR-IR-2006 model with a pole located at 51.045 degrees N latitude, 255.842 degrees longitude and rotating at a rate of 0.2423 degrees/Ma. The parameters of the Amur plate rotation were preliminarily estimated (57.6 +/- 0.5 N, 117.1 +/- 0.5 E, and 0.083 +/- 0.004 degrees/m.y) using results on the Sikhote Alin and Transbaikalian network.
