Abstract: An animal tracking terminal and an animal tracking receiver of an animal tracking system are provided to obtain accurate data on a movement of animals by extending a lifetime of a GPS transmitter. An animal tracking transmitter includes an RF transmitter(210), a GPS receiver(220), a memory(230), a timer unit(251), an RF transmission controller(252), and a power supply(240). The RF transmitter transmits RF signals to a tacking satellite. The GPS receiver receives position data from the GPS satellite. The memory stores tracking information and position data of the satellite. The timer unit calculates a transmission timing based on the tracking information of the satellite and outputs a first interrupt signal for transmitting the position data at the calculated timing. The RF transmission controller is changed from an RF sleep mode to an RF active mode, when the first interrupt signal is received, and transmits the position data to the tracking satellite through the RF transmitter. The power supply supplies power to an animal tracking system.
