Abstract: A device and a method for simulating output power of a solar cell array for a small satellite are provided to control current-voltage simulation data of the output power satisfactorily and easily at a low manufacturing cost by feeding back load current and voltage. A power supplier(260) supplies power to a system of a small satellite. A storage unit(250) stores simulation condition data for a solar cell array. A power controller(271) generates current-voltage simulation data of the output power by reading the simulation condition data from the storage unit and outputs the control voltage to the power supplied depending on the generated current-voltage simulation data. The power controller calculates a new voltage level and outputs the power corresponding to the new voltage level when a difference between load current/voltage fed back from the power supplier and the current-voltage simulation data of the output power is bigger than a threshold.

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.

Abstract: An impulse measuring device of a thruster and a method thereof are provided to increase the data processing speed and to precisely measure the very small size impulse by reducing the various errors. An impulse measuring device of a thruster comprises a swinging offer part(102), a sensor(105), and a data processing part(109). The thruster(101) is fixed at the swinging offer part. The thruster is reciprocated by the swinging offer part around the equilibrium point. The sensor measures the exercise hours of the thruster. The exercise hours of the thruster are the time to thruster pass through the arbitrary point-to-point interval. The amount of change of the exercise hours is the difference between the exercise hours while the thruster is running and the exercise hours while it is not.
