From: Real-time Kinematic Positioning of INS Tightly Aided Multi-GNSS Ionospheric Constrained PPP
Time series of attitudes calculated by GPS, G + R, G + R + B INS aided IC-PPP mode with setting satellite cut-off elevation angles from 10° to 35°; Here ‘GPS 10°’ means use GPS data and set cut-off elevation angle to 10°; for better view, −0.02°, −0.01°, 0.00°, 0.01°, 0.02°, 0.03°, 0.04° and 0.05° shift are added in the results of GPS 10°, G + R 10°, G + R + B 10°, G + R + B 15°, G + R + B 20°, G + R + B 25°, G + R + B 30°, G + R + B 35° schemes.
