Abstract
An improved platform transmitter terminal (PTT) is disclosed for use in an ARGOS type satellite system. The PTT has reduced size, weight and extended life due to a solar array/rechargeable battery power source operating under the supervision of a unique power supply control and protection means. The invented PTT, when used in an ARGOS type system, opens the possibility of tracking, on a global basis, wild animals weighing as little as a few kilograms.
