GNSS management: Wake-up sessions

Background Information

GNSS management setup: Wake-up sessions allows the user to
•
Configure new wake-up sessions.
•
Edit and delete existing wake-up sessions.
•
View information about existing wake-up sessions.
Wake-up sessions define a number of intervals for which the receiver is configured to run. The receiver turns itself on at the configured
start time and starts e.g. logging and streaming as configured in GNSS management:: Logging session and GNSS management: Data
streams. After the configured duration, the receiver stops all activities and automatically shuts down. This is especially useful in field
campaigns where only a limited power supply is available.
•
Up to twenty wake-up sessions can be configured.
•
The maximum time between 2 consecutive start times is 21 days.
•
More than one wake-up session may be active at a time. If at least one session is active any programmed power down
requested by another session will be omitted.
•
If the time between wake-up session is set to zero, the receiver will not power down.
Wake-up sessions can be configured in two ways, using
•
Receiver setup: Wake-up sessions, or via the
•
Logging session wizard. See GNSS management: Logging session for further information.
The time settings will refer to the receivers defined Time zone. To set the receivers Time zone, go to GNSS
management / Site name and coordinates.
When the receiver is powered down, remote communication with the receiver will be lost. If you have no
wake-up session configured, you will not be able to remotely restart the receiver.
Note the following behaviour for a wake-up session
•
If an active wake-up session is configured, the receiver will power down at the end of the first
interval, independent of whether the receiver had been on or off before the start of the interval.
•
Once the receiver is powered down, no remote communication is possible until the next interval.
•
If a power loss occurs during a wake-up session interval (when the receiver is on) and the power

Select the polarity to use the rising or falling edge of the incoming pulse as trigger in
order to record an event.
Accepts Default or User defined calibration values for the particular receiver.
Available if Bias internal is set to User. Sets the calibration value in nanoseconds
for the receiver.
Sets a calibration value in nanoseconds according to the external event device and
cable being used.
If two or more events take place during the time defined in seconds, the first event
will be recorded. Enter 0 to accept all events. The shortest recording time is 0.05 s.
User input. Records up to 80 characters of data with the event record.
