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.
NOTE: 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.
You can use up to 292 rules within one schedule and get as complex as you want (rules
for all biological- and physical seasons, planned field operation, different study or
monitoring questions etc.).
NOTE: Iridium: Field studies have shown that the transmittal of 8 fixes per day in Mode4
– 4 fixes per message) has the best energy consumption / transmittal probability ratio.
Transmittal of more fixes per day will work as well but might result in a higher degree of
unsuccessful transmission attempts. Data will be reach you at some point but that might
take some time.
Recommendation: 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.
After changing the default rules to the user defined rules, you can choose if you like to
send the new schedule only to the selected collar or to all collars found in the Device
Search by setting up the Destination on the left side of the frame.
If you want to create a new schedule the first time (only the default schedule exists in the
collar), a notification window will appear when selecting the GPS schedule frame.
