From: Real-time Kinematic Positioning of INS Tightly Aided Multi-GNSS Ionospheric Constrained PPP
Position differences time series in first 30 minutes calculated by GPS, G + R, G + R + B IC-PPP mode (left) and INS aided IC-PPP mode (right) using different satellite cut-off elevation angles; Here ‘GNSS “X”°’ means use GNSS data with setting the cut-off elevation angle to X°.
