Analyzer of the GNSS simulators parameters

This article presents a navigation signals analyzer. The analyzer used to calibrate signal generators. Calibration data formed the adaptive algorithm. The algorithm is based on quasi-optimal unscented Kalman filter. The model of system contains two fixed terms. These terms describe the direct and reflected signals. The reflected signal arises because there is a mismatch of ports of the analyzer and generator. The parameters of terms are unknown. Special programmed signal imitator is also provided by the analyzer software. This imitator was used to model and investigate the designed signal analyzing algorithms. Calibration of the real global navigation satellite system (GNSS) simulators has been done.
