LEO satellite overview
  • Large Imaging LEO satellites

    (Multispectral)
  • Estimated cost 8 to 50 million US
  • Cubesats

Space Industry Developments
  • International LEO satellite industry structure
  • Countries with space heritage provide in their
    own needs those who require access
  • SunSpace is building upon its South African
    heritage with the objective of entering the
    developing world market with further products
  • Why small LEO?
  • Affordable access to space - existing heritage
  • Complex technical challenges without the cost of
    large programs
  • Current developments
  • Developing world is waking up to small satellite
    possibilities
  • Future expectations
  • Growing international demand for small satellites
    TACSAT as example

SunSpace our role
  • International small satellite industry
  • Many countries competing for developing world
    small satellite orders
  • SunSpace competing as part of team RSA
  • Local space industry
  • SunSpace is part of a large number small RSA
    companies that contribute to local space effort
  • SunSpace provides both small satellite hardware
    and software as well as expert training for small
    satellite design, development testing and
    operations engineers.
  • Government support
  • The international competition is won only as a
    national team effort

Sumbandilasat
  • What is it?
  • 84 kg earth observation satellite with a
    multispectral imaging of 6.25m GSD at 500km. Can
    see the same point in RSA every 3-4 days.
  • Pathfinder objective is to increase scientific
    and engineering knowledge in space systems
  • Satellite contains some heritage, some newly
    developed systems
  • What is it good for?
  • Designed and tested for operational use provide
    scientifically useful images if operating as per
    design specifications
  • Images will provide further scientific
    information for assessing ground cover,
    agricultural crop analysis, forestry composition
    analysis, water analysis and land use
    applications
  • Provide clear indication of progress in RSA
    technical design, manufacturing and operating
    capabilities to the international community
  • Signal for high level technical expatriates to
    return to our country

Satellite Control Issues
  • GEO (we do not operate there)
  • Mandatory requirement for safe removal of
    satellite from orbit.
  • Safe removal applies also to the GTO and the
    insertion rockets
  • Safe removal mechanisms built into the satellite
    design
  • Proof of operation for safe removal mechanisms
    required before launch
  • MEO (we do not operate there)
  • Removal requirements are not stringent or
    enforced
  • No parked orbital slot in relation to terra
    location
  • LEO (Yes, we operate here)
  • No mandatory control
  • Technical expertise required to launch into an
    unoccupied orbit

Other Controls in Space (1)
  • Some local controls for space
  • Missile Technology Regime NPC (DTI),
  • Prohibits and controls the transfer of
    technologies in spacecraft for use in
    intercontinental ballistic missiles
  • Wassenaar Arrangement NCACC (DOD),
  • Control and tracks specific technologies used in
    spacecraft to prohibit their re-use in
    conventional arms such as other missiles or
    targeting systems
  • Council on Space Affairs (DTI), ICASA (DOC)
  • Controls the launch of all spacecraft from South
    African soil and South African spacecraft from
    other countries.

Other Controls in Space (2)
  • International LEO Orbit Issues
  • The UN COPUOS is trying to introduce legislation
    to limit or eliminate LEO space debris, but
    accept that existing debris cannot be removed
    because
  • There is too much debris comprised of separation
    hardware and spent rocket final stages and the
    like.
  • There is no affordable existing system that could
    be used to remove the existing debris.
  • The UN COPUOS accordingly is concentrating on
    promoting the responsible use of space as the
    only practical means to limit or avoid the
    proliferation of space debris. The most important
    items of space debris to be avoided is the
    following
  • Since the titanium tanks used for hydrazine do
    not burn up upon re-entry, they have to be
    completely vented (emptied) at end of life to
    avoid contamination when they fall back to earth
    as hydrazine is extremely poisonous.
  • The use of nuclear reactors to power satellites
    in LEO orbit are now regarded as irresponsible
    space use in the extreme. Most responsible
    nations will not launch any LEO satellite with a
    nuclear reactor power source. Nuclear power
    sources are the only possibility for outer space
    exploration missions where insufficient solar
    energy is available.

Other Controls in Space (3)
  • UN COPUOS treaties
  • LEO orbit space bodies are difficult to regulate
    without international cooperation forums such as
    the UN COPUOS
  • Access to international markets for satellite
    manufacturers such as ourselves depends on our
    country being seen as a responsible space user
  • UN treaties provides internationally recognised
    platform for responsible use by guarding against
    misuse of orbits, launches and provide legal
    cover for when space debris lands on ones soil
  • Recommendation on UN treaties
  • SunSpace gives its unqualified support to the 2
    UN treaties namely the Liability Convention and
    the Registration Convention under consideration
    and urges Parliament to ratify both!
