Satellite
Transmitters
The canoes are equipped with
transmitters. The transmitter starts sending signals to the satellites.
The satellites collect the data and retransmit it to the Argos centers for
processing. The watershed center retrieves the data, builds a aerial
view image and provides these information online.
These transmitters are produced by North
Star. |
Platform
Transmitter Terminal
The
transmitters offer long operational life, high
location accuracy, programmable duty cycles with multiple seasons,
integrated sensors, and package sizes ranging from 16-120 grams.
Conventional VHF transmitters with duty cycles controlled by the PTT
can be built into the PTT. Sensors available for integration with all
North Star PTTs include temperature, activity, atmospheric pressure,
battery voltage, duty cycle season, transmission counter, and
accelerometer.
