CUAVA-1

ARC Training Centre for CubeSats, UAVs & Their Applications


Mission Motivation and Objectives

The objectives of CUAVA’s flight programs are to train future engineers, industry  people, and scientists in space and UAV applications and in commercialisation, to increase the capabilities of CubeSats and UAVs, to solve particular research problems, to flight-test new applications and services,  and to develop the future workforce of the space and UAV industries in Australia.

The CUAVA-1 satellite will be the first satellite designed, developed and launched by the CUAVA Training Centre.  CUAVA-1 will be a stepping-stone for the Training Centre to more refined missions in the future. It will fly first-generation payloads developed by CUAVA partners and directly address the Centre’s goals.

CUAVA-1 is a 3U CubeSat that will carry significant heritage from the QB50 CubeSat INSPIRE-2. It is the second CubeSat to be developed in quick succession by the Universities of Sydney and New South Wales after the launch of the 2U INSPIRE-2 (AU03) satellite which was deployed from the ISS on the 26th of May, 2017, as part of the QB50 initiative. CUAVA-1 will build on the previous INSPIRE-2 design utilising COTS components and payloads provided from the University of Sydney, the University of New South Wales (UNSW), and CUAVA Industry Partner Air@Wave Communications.

The CUAVA-1 mission will:

(1) link with the international radio amateur union for education, outreach, and increased data downloads,

(2) observe the Earth with a novel hyperspectral imager,

(3) use a GPS instrument to explore radio occultation and the reception of GPS signals scattered off the Earth (as well as provide a backup determination of the CubeSat’s location),

(4) investigate Earth’s plasma environment and associated space weather with radiation detectors, and

(5) explore the performance of a state-of-the-art communications payload.

CUAVA-1 will be delivered in Q4-2019 to Space-BD in Japan, and is now under development at the University of Sydney, UNSW, and Air@wave Communications.  Testing will be carried out at the Advanced Instrumentation and Technology Centre at the ANU.  

Satellite bus and payload

CUAVA-1 is a 3U CubeSat with four experimental payloads:

  • Hyperspectral Imager developed by the School of Physics, University of Sydney.
  • GPS Instrument developed by Australian Centre for Space Engineering Research, University of New South Wales.
  • Radiation Detector developed by the School of Aerospace, Mechanical and Mechatronic Engineering and the School of Physics, University of Sydney.
  • High speed communications package developed by Air@Wave Communications.

The bus consists of commercial off-the-shelf (COTS) components for each sub-system listed below:

  • Electrical Power System (EPS): GOMspace P31U with two lithium-ion battery cells and 7 solar panels consisting of two Azurspace triple-junction solar cells in series in each panel, with sun sensors integrated. The solar panels are provided by Air@Wave Communications.
  • Command and Data Handling(C&DH): Innovative Solutions In Space on-board computer (OBC).
  • Communications: Innovative Solutions In Space crossed dipole pair antenna with aVHF Uplink/ UHF downlink transceiver.
  • Attitude Determination and Control System (ADCS): AdCole Maryland integrated one reaction wheel system MAI-400, also including three magnetorquers, a three-axis magnetometer and a gyroscope. Sun-sensors integrated into solar panels used as inputs to the ADCS system.
  • Structure: Innovative Solutions in Space 3U PC104 form factor structure.
