Abstract:
The present invention relates to an electronic ground support equipment verification apparatus for a satellite RF test and a method thereof. The apparatus according to the present invention includes an RF hardware part which includes RF equipment for a plurality of satellites, is connected to electronic ground support equipment for the RF test with RF uplink and RF downlink, and reproduces the situation of transmitting and receiving an RF downlink signal and an RF uplink signal of an RF level; and a controller which controls the RF hardware part and checks the state of the RF hardware part. According to the present invention, the electronic ground support equipment for the RF test is verified without connecting to the satellite by providing the electronic ground support equipment verification apparatus for the satellite RF test which reproduces data information and an RF signal which the electronic ground support equipment for the RF test requires.
Abstract:
PURPOSE: A test device for enabling the valve control of a satellite and a valve control method of a satellite using the same are provided to stably deal with the propellant of a satellite by controlling the valve of the satellite. CONSTITUTION: A test device for enabling the valve control of a satellite comprises a control module (110) and an interface part (120). The interface part connects the control module and a satellite in which fuel is injected to each other. The interface part outputs a valve control signal from the control module to the satellite and receives a valve state signal from the satellite. The control module controls the opening and closing of an isolation valve in the satellite by supplying the valve control signal to the isolation valve and determines whether the isolation valve is opened or closed by receiving the valve state signal from the interface part.

Abstract:
A satellite downlink packet dynamic structure implementation method is provided to enable a manager to define a satellite downlink packet structure by desired remote measurement items, thereby smoothly managing a satellite. A plurality of mom mnemonics corresponds to packet group ID, packet ID and a remote measurement value. A packet to be used in a downlink of a satellite is generated by selecting the mom mnemonics(S310). The generated packet is stored in a packet table of an automatic satellite test device(S320). The generated packet is transmitted to the satellite through a satellite command. The transmitted packet is stored in a packet table of the satellite(S330). The satellite command comprises the packet group ID, the packet ID and argument values of the mom mnemonics.
