Caution: If you select a setting that does NOT resurvey, and subsequently relocate
your unit (antenna) by more than 100m, u-blox M8T and Trimble Res-T receivers
will NOT detect the new position, and hence provide an incorrect time.

page180.

Available GNSS Receiver Dynamics Settings
The following Receiver Dynamics settings are available:
Land (Resurvey): [default]
When used with the Mobile Receiver Mode, the receiver is adjusted for typical dynamic
land-based applications.
When used with the Standard Receiver Mode, this setting also will automatically initiate
a resurvey after SecureSync reboots, in order to account for a possible relocation.
Sea: The receiver dynamics will be optimized for mobile motion patterns typical with
marine applications, resulting in greater timing accuracy, and avoiding premature loss
of synchronization.
Air: The receiver dynamics will be optimized for acceleration forces typically exper
ienced in civil aviation applications.
Stationary (No Resurvey): In Standard Mode, the receiver is set to a non-dynamic value
for stationary applications.
There will be no automatic resurvey after a reboot. Should a unit be relocated, you
need to delete its position, thus initiating a new survey.
The following table illustrates the interdependence between Receiver Dynamics, Receiver Mode
(see "Selecting a GNSS Receiver Mode" on page172) and receiver type:
