SME-SAT Surrey Space Centre

The Surrey Space Centre in Guildford has released a Softstack Integration
time-lapse video of the SME-SAT CubeSat.

The mission objectives a

A: Outreach – The satellite will provide beacons for which amateur
satellite users and ham radio users will be able to receive.

B: 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: 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: 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: 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: 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: 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.

The IARU coordinated frequency for the satellites 9k6 RC-BPSK AX.25
downlink is 437.150 MHz.
