State and dynamic precision research using two GPS receivers with RTK

Given the research work presents the results of GPS systems for dynamic precision estimation, using the real time kinematic (RTK) phase measurements of position with two receivers. Receiver's antennas have constant distance between them. The network of base stations EUPOS-Riga and LATPOS was used to correct errors. State estimation results are presented as well. The GPRS data exchange among correctional station and receivers was used. The results of precision estimation reveal that centimetre accuracy may be achieved using the fixed solution. Precision of state estimation (course and roll angles) depends on antennas base.
