You can define the following parameters:
System
UTC correction the collars use the UTC (Universal Time Coordinated) time
which is also used by the GPS satellite system. It differs to
your LMT (Local Mean Time). To give an example: LMT in
Germany is +2 hours to UTC, UTC correction: +2 hours. You
can set the UTC Correction in GPS Plus X and the collar will
then translate your in LMT programmed schedule internally.
Recommendation: stick to either way (UTC correction or
UTC schedules) for all collars and document it carefully. It
easily happens to get confused especially if you ask us to
do some changes.
Sensors
GPS Skip Count
The GPS skip count refers to the satellite communication
enabling you to set a number of GPS location which will be
conducted and stored but are not added to the transmission
pool. (Example: a Globalstar collar with 2 fixes a day and
skip count 1, will send only one data message with 1
location per day).
Mortality Period
Here you can set a time span using the up- and down
arrows. If the activity values remain under the set threshold
(64 within a 0-255 range, changeable by VECTRONIC) for
this time span, the animal is assumed to be dead and a
mortality event is triggered. The default value is 24h with
have been successfully used in many studies.
NOTE: Please consider which values might reflect animal
behavior at best. A short period might lead to false alarms
as the animal is only resting.
