| The present invention relates to a variable thermistor constant current apparatus for satellite and a method thereof. The present invention comprises the following: a constant current selecting part for outputting a constant current out of a plurality of constant currents of which the intensity varies from each other inputted from the outside; a constant current distributing part for outputting the inputted constant current after receiving constant current outputted from the constant current selecting part; and a plurality of constant current providing parts connected to a plurality of outputting channels. The constant current providing part connected to the outputting channel selected by the constant current distributing part selectively outputs constant current outputted from the constant current distributing part to one of the thermistors. According to the present invention, since a constant current circuit which can satisfy various constant current values required by satellites can be provided by designing proper software, constant current providing circuits required for each channel to provide constant currents for a plurality of thermistors are unnecessary, thereby reducing an area of board and the costs. Also, costs for tests and redesigning hardware can be reduced since converted constant currents can be provided even when a constant current value required for a system is converted after designing hardware equipped with the circuit is completed.
