SAIEE WCC | MDASAT – A Nanosattelite Constellation to Improve the South African Maritime Domain Awareness Capability



SAIEE WCC | MDASAT – A Nanosattelite Constellation to Improve the South African Maritime Domain Awareness Capability
MDASat is a proposed nanosatellite constellation that will provide maritime domain awareness services to the African continent. The mission will be developed by Amaya Space, a spin-out company of the nanosatellite programme at the Cape Peninsula University of Technology (CPUT). The programme is funded by the South African government's department of Science and Technology in support of Operation Phakisa, an initiative with the goal of unlocking the economic potential of South Africa's maritime domain which, by estimation, could contribute up to R177 billion to the GDP and 1 million jobs by 2033.

 Title                                                    MDASAT – A NANOSATELLITE CONSTELLATION TO IMPROVE THE SOUTH AFRICAN MARITIME DOMAIN AWARENESS CAPABILITY

 SYNOPSIS:

 MDASat is a proposed nanosatellite constellation that will provide maritime domain awareness services to the African continent.  The mission will be developed by Amaya Space, a spin-out company of the nanosatellite programme at the Cape Peninsula University of Technology (CPUT).  The programme is funded by the South African government's Department of Science and Technology in support of Operation Phakisa, an initiative with the goal of unlocking the economic potential of South Africa's maritime domain which, by estimation, could contribute up to R177 billion to the GDP and 1 million jobs by 2033.

The ZACube series of satellites is being developed within the nanosatellite programme at CPUT which to date has produced two satellites: ZACube-1, also known as TshepisoSat, launched on 21 November 2013, and ZACube-2, launched on 27 December 2018.  These satellites are used as technology demonstrators that will feed technology into the MDASat programme.  The MDASat constellation will support the Automatic Identification System (AIS), a terrestrial radio system used for collision avoidance among ocean vessels, as well as the VHF Data Exchange System (VDES) which is being designed as an extension to AIS, greatly expanding its capabilities, adding additional services and including support for satellite links.  AIS was designed to use terrestrial coastal AIS stations to communicate with ships and its coverage is typically limited to several tens of nautical miles from the coast. The use of an AIS receiver on a satellite can potentially provide global AIS coverage, removing the aforementioned terrestrial coverage limitation.  ZACUBE-2, developed as a precursor satellite for the MDASat mission, is a three-unit CubeSat that carries an advanced software defined radio (SDR) payload that implements an AIS receiver.  The SDR payload is reconfigurable in-flight in anticipation of the implementation of the full VDES standard, as well as other communications applications.

 An overview of the MDASat mission objectives, technology and value proposition, as well as preliminary ZACUBE-2 mission results, will be presented.

 

CURRICULUM VITAE:

 Francois Visser is an RF and microwave engineer with more than 20 years of professional experience in the development of radio communications products for microsatellites.  He is the chief engineer for the Africa Space Innovation Centre (ASIC) at the Cape Peninsula University of Technology (CPUT) where he leads the research and development efforts of a group of engineers who develop nanosatellite missions and subsystems, with a focus on RF and microwave communications.

 He completed his MSc in Electronic Engineering in 1997 at the University of Stellenbosch where he participated in the development of SunSat, South Africa’s first satellite, which was launched in 1999.  Thereafter he continued working in South Africa’s satellite industry, participating in the development of a number of space missions, including South African satellites SumbandilaSat, Tshepisosat, ZA-Aerocube and nSight-1
