Physical Specifications for 70g ARGOS/GPS Solar Transmitter:

Dimensions: L 3.9” (98) x W 1.5” (38) x H 0.98” (25) (mm)*
Weight: 68 to 75 grams
* Antenna and harness mounting tubes not included in these dimensions
Antenna: Hard nylon coated flexible stranded marine grade stainless steel, 7.0” (180 mm) long, protruding from the back edge of the transmitter 45 degrees to the bottom face.


The housing is constructed from an epoxy glass reinforced lightweight composite material, plated on the inside with a contiguous metal coating. The final seal is a metal to metal solder. The unit is therefore hermetically sealed and remains so during changes in temperature and humidity.


The 70g GPS solar transmitter comes complete with sensors to measure temperature, its own
battery voltage and animal activity, as well as a sixteen channel GPS receiver that calculates position,
altitude, heading and speed.
