2.3e Always on Mode
Depending upon your programming, your GPS unit will attempt to acquire locations
every 5, 10 or 20 seconds. These attempts may be programmed to begin at some time and
date in the future. This feature is not available in conjunction with the activity senor
option.
2.3f Activity Sensor
The activity sensor operates independently of the GPS and will record data based on your
desired specifications. It is user programmable to meet your needs. To learn more,
please see
section 6.3
. This feature is available by itself or in conjunction with the Smart
GPS feature. It is not available in conjunction with the always on programming mode
option.
2.3g Smart GPS Sensor
The smart GPS feature influences the operation of the GPS based upon the study animals’
activity level. The purpose of the smart GPS feature is twofold. First, it may
dramatically increase the number of successful GPS location attempts output from the
unit. Second, it may dramatically increase the battery life of the unit. This is especially
important for very small GPS collars and backpacks. This feature is available as a stand
alone option or in conjunction with the standard activity sensor. It is not compatible with
the always on programming mode option.
2.3h Mortality Indicator
Your VHF transmitter is equipped with a motion detector. This will detect movement.
After a specific period of time (pre-determined by the user during the ordering process)
has elapsed without any motion detected, the VHF pulse rate will double, indicating
mortality. The mortality event is not stamped in the memory. Only available by request
for GPS units that include a VHF transmitter.
2.3i VHF Transmitter
Your unit contains a VHF transmitter that will be on from the moment you remove the
magnet from the transmitter from the white dot on the GPS unit. Consult your packing
list for the battery life of this transmitter. The VHF transmitter will help you locate the
unit and, via its motion detector, whether the animal is alive or dead.
