Headline Details: This is a 3U CubeSat mission. The objectives are: A: Outreach - The satellite will provide beacons for which amateur satellite users and ham radio users will be able to receive. B: Technology Demonstration -1: Space qualification and performance characterisation of sensors. • High performance COTS Gyroscopes (x3), • High precision MEMS accelerometers, • 2 Aperture Star Camera, At a later point in the mission these will be used in conjunction with the ADCS to characterise the closed loop performance of the sensors. C: - Technology Demonstration 2: Performance characterisation of Nano-Control Moment Gyros (CMGs) for agility The mission is equipped with 4-Nano-CMGs in a pyramid configuration for ADCS. This part of the mission will evaluate the performance of this system on the ADCS and agility of the satellite. D: - Technology Demonstration 3: Space qualification and performance characterisation of the EPS The EPS for this mission has heritage from the Delfi-C3 and other missions and includes additional improvements to be demonstrated on this mission E: - Technology Demonstration 4: Smart Thermal Radiation Devices (STRD tiles) SME-SAT is equipped with a number of STRD tiles on the outside faces of the satellite for passive thermal management of the internal structure. F: - Technology Demonstration 5: Flux Gate Magnetometer The mission contains a scientific grade miniaturized flux gate magnetometer that sits on the end of a deployable boom to improve the performance of the sensor. This payload will be switched into the ADCS for evaluation of performance during parts of the mission but is not the primary magnetometer for ADCS. G: - Technology Demonstration 6: GPS SME-SAT also contains an experimental GPS system that will be switched into the ADCS loop at stages in the orbit to evaluate the performance of the system. Planning a 9k6 RC-BPSK UHF downlink using AX25. No launch details have been provided.
