Biarri GPS Receiver Project

Project Biarri is 5-Eyes Cubesat mission in which Australia has been working with the New Zealand, Canada, the United Kingdon and the United States to explore cubesat formation flying, better understand the drag and lift forces experienced by the CubeSats and verify the performance of the ACSER developed Namuru V32R3A GPS receivers and the Electro Optic Systems (EOS) space situational awareness infrastructure.

With delivery of the four flight model Namuru GPS receivers to the Defence Science and Technology (DST) Group in late 2013 and assembly, integration and testing to taking place at the US Air Force Research Laboratories (AFRL) in 2014 and early 2015, it was fully expected that the Biarri mission spacecraft would have been deployed last year. However, as is often the case with such projects, the launch has been delayed.

The latest advice from DST Group is that the Biarri mission is to be split into two separate missions; namely a risk mitigation mission called Biarri Point in which a single spacecraft is deployed in October 2016, followed by deployment of the remaining three CubeSats in 2017 or 2018 called Biarri Squad.

In the meantime, UNSW has signed a contract with DST Group to provide on-going support for the Namuru V32R3 GPS receivers. This support will be vital once Biarri Point has been deployed and it becomes necessary to analyze the performance of the receiver and undertake the various experiments designed for the mission.

ACSER also continues to work with DST Group on additional projects.


In Summary:

The Project

  • Biarri is a collaborative cubesat program, led by BAE Systems.
  • The Australian Centre for Space Engineering Research will deliver a space-qualified GPS GPS L1-only receiver ultimately for use by the Defence Science and Technology Organisation's (DSTO) Intelligence, Surveillance and Reconnaissance Division (ISRD). The GPS receiver will be flown on a Colony-2 cubesat.
  • Australia is participating in Biarri with four international partners.
  • The satellites will be launched in 2014. 

The Biarri Project will:

  • Develop, manufacture and functionally test six Namuru V3.2 space qualified GPS receiver cards.
  • Deliver interface documentation for the interface of the Namuru GPS receiver.
  • Develop ground based software to take the output of three Namuru GPS receivers installed in formation flying satellites and improve the accuracy of the reported position.
  • Assist with the integration of the GPS receiver cards into the satellite.
  • Deliver software to exercise the Namuru GPS receiver for use during space qualification testing and integration.
