The Receiver Mode function allows the GNSS receiver to operate in either a sta-
tionary mode (“Standard” or “Single Satellite” modes), or in a mobile mode envir-
onment e.g., in a vehicle, ship or aircraft.
Offset [ns]: to account for antenna cable delays and other latencies
Receiver dynamics: to optimize performance for land, sea or air operation
The ability to delete the stored GNSS position information (latitude, longitude and
antenna height).
The option to determine when a resurvey is to be performed (supported only by
newer GNSS receivers).
To configure the GNSS Receiver Mode for your VersaSync unit:
1.
Navigate to INTERFACES > REFERENCES: GNSS0. The GNSS0 Status panel will
open.
2.
Select Edit in the bottom-left corner. The GNSS 0 configuration window will open:
3.
Select the desired Receiver Mode, and click Submit.
GNSS Receiver Modes
The receiver modes are:
Mobile Mode: This is the default mode for VersaSync. In Mobile Mode, GNSS sur-
veys (see below) will NEVER be carried out since the position status is updated in
near real-time. VersaSync will go into synchronization shortly after beginning to
track satellites.
Standard Mode: While the Standard Mode tends to be the most accurate GNSS
Receiver Mode, it can only be used for stationary applications, i.e. the VersaSync
unit must not be moved. In Standard Mode the so-called GNSS survey will be per-
formed as soon as at least four GNSS satellites become available and no previously
carried out survey was found. Upon completion of the survey the GNSS receiver will
lock-in the calculated position and will enter Standard Mode. Once the survey is com-
pleted, less than four satellites will provide a valid Time and 1PPS signal.
Single Satellite Mode: This mode is designed for stationary applications which can-
not track at least four GNSS satellites for at least 33minutes continuously in a 12-
