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).
The option to select your constellation types
To configure the GNSS Receiver Mode for your SecureSync 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:
Standard GNSS Receiver Mode
The default GNSS receiver mode is the Standard Mode: It is the most accurate, and hence
the preferred GNSS receiver mode.
The Standard Mode can be used only for stationary applications, i.e. the SecureSync unit
will not be moved. Also, it must be able to track initially at last four satellites in order to com-
plete the survey. (Once the survey is completed, less than four satellites will provide a valid
Time and 1PPS.)
In the Standard Mode the GNSS survey will initially be performed, once at least four GNSS
satellites become available. The GNSS survey is used to determine the exact position and
time; it takes 2000 seconds (33 minutes) to complete a survey. During the survey, the
