1.4.3. Ellipse-D orientation and navigation performance
For each application, the accuracy parameters are defined in different positioning modes, explained below:
●
SP refers to Single Point mode and is the default L1/L2 GPS fix quality
●
RTK stands for Real Time Kinematics with a typical 1 cm accuracy position
●
Odometer Aiding is specified when an odometer provides velocity (automotive applications)
●
PPK refers to the Post-processing Kinematic solution
1.4.3.1. Land applications
All specifications are valid with DMI (odometer) aiding for typical land applications trajectories.
