The following table lists all available Dynamic modes:
Table 4.1 Supported Dynamic GNSS Operating Modes
If the external GNSS receiver is a timing uBlox reciever it is capable of running in a stationary mode
with Position Auto Survey called Position Hold Mode. This mode increases timing stability by
storing the position into memory, and solving the GNSS signal only for time as the position is not
expected to change. This allows operation with only one Sat vehicle, or over-determination of the
timing pulse. Two modes can be selected for Auto Survey operation (see section
description of the GPS:TMODE command):
1) Manually setting Timing Mode to ON with a hard-coded position in NVRAM
2) Enabling Auto Survey to start automatically after power-on by setting Timing Mode to
RSTSURV
If either one of the above two GPS:TMODE Auto Survey/Position Hold modes is selected, the
GPS:DYNAMIC:MODE command is disabled internally and its setting is ignored as the unit does
not expect any motion on the antenna. In this case, the dynamic state as programmed into the GNSS
receiver is set to STATIONARY independent of the user selection for GPS:DYNAMIC:MODE.
The current dynamic state being applied to the GNSS receiver can be queried with the command
GPS:DYNAMIC:STATE?
This command is only supported with an external uBlox GNSS receiver.
