Navigation Single Board Receiver NavSBR鈩�
Overview
刘玥首次大战黑人implemented the receiver as an embedded single frequency 12-Channel GPS receiver ported to a single 3U cPCI card. The NavSBR is available as a standalone assembly or a single 3U cPCI card for direct chassis integration.
Generated observables are filtered using GPS-Enhanced Onboard Navigation System (GEONS) technology (under license from GSFC) providing high-quality solutions by employing an extended Kalman filter (EKF) augmented with physically representative models for gravity, atmospheric drag, solar radiation pressure, clock bias, and drift to provide accurate state estimation and a realistic state error covariance.
