The following table illustrates the interdependence between Receiver Dynamics, Receiver Mode
(see "Selecting a GNSS Receiver Mode" on page153) and receiver type:

Notes:
The u-blox M8T receiver now uses Land to indicate it will RESURVEY on reboot, and Sta-
tionary to indicate it will not resurvey after reboot.
