Sequence
The sequence is a time span within the period length between you
like to take GPS positions. Here you can define:
Offset
– it defines
the time span between the start of the period and the recording of
the first GPS position;
Duration
– period in which the GPS
positions will be recorded with the Fix Rate repetition;
Fix Rate
–
GPS position recording repetition rate.
Please note that you can
only take GPS fixes within the time span of the period. This way,
the sum of offset and duration must be smaller than the value of the
defined period length. If you like to take only 1 GPS fix per
sequence, the fix rate can equal the duration value. If you have
already two position recordings in one sequence, you can delete the
other sequence in the rule editor.
Figure 3: Survey Collar GPS Schedule frame
As the Survey collar
can only take up to two positions per day
, GPS PLUS X will check if
there are not more than two fixes per day configured. If the rules are set up in a way that more
than two positions are recorded every day, you will receive an error message. You can define
max. 292 GPS schedule rules.
Note:
For safety reasons you should define at least one schedule starting on 01.01.2000. If the
collar's time is reset for any reason, the timer will start at this date and will attempt to take one
fix per week until another schedule starts or until the clock is set to the correct UTC time by a
successful GPS fix.
Note:
The collar will take on GPS fix per week when all schedules rules are in the future or
already outdated.
Note:
With each successful GPS fix, the collar time is automatically adjusted to the correct
UTC time, corrected by your UTC correction (if enabled). It is thus not possible to
synchronise the collar with another time, than the GPS satellite system’s time. Also, UTC
correction cannot be enabled by sending the local mean time to the collar.
