摘要： 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.

摘要： PURPOSE: An enhanced ground based precise posture determination method of a low-orbit imaging satellite is provided to accurately determine the posture of the satellite by dually using gyro measurement data and star tracker measurement data. CONSTITUTION: Gyro measurement data and star tracker measurement data are obtained in different intervals through a gyro sensor and a star tracker using a dual MIL-STD-1553 bus communication device (S100). The gyro measurement data and the star tracker measurement data are stored and transmitted to a ground station (S200). A posture quaternion estimated value is repeatedly predicted until the star tracker measurement data is received after calculating an angular speed by restoring the transmitted gyro measurement data again (S300). A modified value is calculated by using the posture quaternion estimated value and the star tracker measurement data, and an error posture quaternion is applied as a corrected value by using the modified value (S400).

摘要： A module for controlling a mass memory of a satellite is provided to increase processing efficiency of data stored in the mass memory and correctly download the stored data to the ground in a needed period by advancing a command of a CPU with priority set in hardware. An access arbiter(110) determines an input signal cycle applied to the mass memory(30) among the input signal cycles for multiple tasks to be processed on the basis of the control from the CPU of the satellite by the set priority. A multiplexer(120) generates a control and access signal to be applied to the mass memory according to determination of the access arbiter. An error corrector(130) calculates an ECC(Error Checking and Correction) code value for correcting an error generated in the mass memory. An initializer(140) sets up operation configuration by setting a register value of the mass memory. A task unit(150) sets up, generates, and stores a cycle signal for executing each task by the control of the access arbiter.

The first CRLH meta material transmitting line changes a phase of a signal as a first angle. The second CRLH meta material transmitting line changes a phase of a signal as a second angle. A phase change according to a frequency change of the first CRLH meta material transmitting line and the second CRLH meta material transmitting line is regularly maintained. A first output signal of the power divider is supplied to the first CRLH meta material transmitting line. A second output signal of the power divider is supplied to the second CRLH meta material transmitting line.
