i-INSPIRE (initial-INtegrated SPectrograph, Imager and Radiation Explorer)is a collaborative project of School of Aerospace, Mechanical andMechatronic Engineering and the School of Physics within the University ofSydney. It aims to verify the ability of a 1 kg tube-satellite tocarry advanced space and astronomical payloads (a radiation counter,photonic sprectrograph, and a CMOS imager). As the first nanoSat to befully constructed by one Australian university and to be launched intospace, the i-INSPIRE project will be a prototype for future morecomplex nano-satellite platforms. The satellite platform distributes thepower, communication and control subsystems into three individual PCBboards, respectively. Observational data from payloads will be collectedand stored in external memory, which is connected to the microcontrollerby an SPI interface. A FM transceiver, the main part of communicationsubsystem, will work in the UHF band and initially be in receivingmode. After obtaining a confirmation signal from the groundstation, the microcontroller will transmit house-keeping and payloaddata to the ground station at the University of Sydney. The additionof a nano IMU (Inertial Measurement Unit) is being considered todetermine the current attitude of i-INSPIRE, in order to complementand confirm the pointing inferred from the imaging camera.
