Before the GPS Collar can log its first GPS fix, it will need to acquire almanac data. The GPS
Collar will do this automatically when it tries to log a GPS position fix. If it determines that it
doesn't have valid almanac data, it will abandon trying to log a fix and it will get an almanac
instead.
Alternately, you have the option to force the GPS Collar to get current almanac data by clicking
the Acquire Almanac button in the ATS
Fixes software. The collar will need at least twelve
minutes while receiving satellite information to receive almanac data. Make sure the GPS
antenna is pointing towards the open sky during this process.
Interpreting the VHF Beacon Beep Patterns
The GPS Collar includes a VHF transmitter that can be used to locate the collar and/or determine
its status. The VHF transmitter can be scheduled to run continuously or only during a certain
interval of the day. It can be programmed to stay off for up to 23 hours each day in order to
extend GPS Collar life. The VHF transmitter also has some obligatory beep patterns which you
will hear regardless of whether the transmitter was scheduled to be active or not.
The different beep patterns the VHF transmitter uses are based on either a 48 pulses per minute
(ppm) rate, or a 27 ppm rate. To your ear, 48 ppm will sound like one beep per second. The 27
ppm rate will sound like one beep per every two seconds. Some beep patterns have double or
triple pulses, which are used to indicate various operating conditions to the listener.
If the VHF transmitter is scheduled to operate, the collar operating condition is indicated
by the beep patterns below:
Normal VHF = 48 ppm.
Mortality VHF = 27 ppm (double pulse and then single pulse, repeating).
Last GPS fix successful = Normal VHF (48 ppm) with a double pulse on the 6
th
pulse.
Last GPS fix failed = Normal VHF (48 ppm).
Obligatory beep patterns indicate the following operating conditions:
Reset/Startup/Not programmed Collars = Slow triple pulse and then single pulse at 48ppm.
Collar attempted break off and failed = Double pulse at 27 ppm (much slower than normal
VHF beep pattern).
