- Collar
- Each collar contains a GPS receiver, a radio modem for data communication,
an independent VHF tracking beacon, sensors and a computer/memory
module. Collection and storage schedules for GPS position fixes and
sensor measurements are user specified via a UHF data communication
link with the command unit. Data is stored until purposefully erased
by the user following unit interrogation.
- Modem
- A link may be established as frequently or infrequently as individual
study requirements dictate. The link is fully bi-directional and may
also be used to:
- Download Stored Data
- Modify the current GPS fix schedule
- Provide information on remaining operational (battery)
- Upload satellite almanac data for use by the animal unit's
GPS receiver.
- Command Unit
- The command unit is a battery-powered instrument which provides
for command, control and interrogation of the animal borne collar.
A portable host computer manages transport and session services for
the network and also provides a windowed, menu-driven interface for
user control of system parameters, formatting and storage of received
data and system diagnostics.
