SmallSats and international stability
  • Earth Observation satellites were originally
    developed by the military East West and
    succeeded in stabilising the Cold War
  • Earth Observation from space used to be an
    activity exclusive to super-powers or wealthy
    nations due to the extremely high cost of the
    large satellites, their launch and operation in
    orbit
  • Small satellites have made Earth observation from
    space accessible to virtually every nation
  • Images lt3 metres GSD/pixel have military/security
    utility modern small satellites now provide
    this capability at greatly reduced cost
  • Not only optical EO constellations small
    satellites providing SAR (Germany) and ELINT
    (France) now exist, although more expensive
  • Small satellite missions provide non-aggressive
    situational awareness to avoid surprise thus
    defuse tension
  • Microsatellites often quoted (by established
    space powers) as a proliferation threat but
    rather they are a disruptive technology

3
Overview
  • What are Small Satellites
  • Introduction to Space _at_ Surrey
  • Current small satellite capabilities
  • Where is it leading?
  • Implications for Security from Space

4
What are Small Satellites?
Mass Cost Time Large 1000kg 200M 10yrs
5
What do small satellites offer?
  • Lower entry cost to space
  • Quick response from concept to operation
    response space
  • More missions within the same budget
  • Constellations swarms become financially viable
  • Enable responsive space
  • Independent access to the high ground of space
  • Stimulate
  • - new commercial markets
  • - new thinking regarding military space
  • Like the PC space is now accessible to a far
    wider community
  • Like the PC the advantage is by networking in
    numbers to increase temporal resolution/response
    and resilience

6
How are they different?
Achieved through a different approach to space
leveraging the enormous investment in the
development of modern consumer products using
microelectronics MEMS and adapting them to use
in space
producing rapid-response, highly capable, yet
low-cost small satellites built using advanced
terrestrial technologies
Changing the economics of space
7
Small satellites for responsive space?
There are 3 components to the responsive small
satellite capability
  • Low cost, rapid small satellites
  • Readily available low cost launches
  • Low cost autonomous orbital operations

Conclusions Small Satellites for Security
Small satellites have reached a level of
capability that is of military/security relevance
low costs rapid production timescales are
consistent with use in military/security
operations
  • Constellation or swarm of small satellites with
    complementary sensors Electro-Optical, SAR,
    ELINT/SIGINT
  • Providing capability for co-located,
    contemporaneous, comparable collection of data
    when required
  • Performance parameters specified with
    complementary fields of regard to facilitate
    cueing fusion of data in network enabled context

47
Conclusions Small Satellites for Security
  • Space is no longer the preserve of super-powers
    it is accessible at an entry level to every
    nation in an affordable manner using COTS
    technologies
  • The ability to have widespread, rapid and
    independent surveillance from space by many
    nations helps reduce surprise and
    misunderstandings
  • Surveillance from space is non-aggressive (open
    skies policy)
  • This can be achieved by numbers of low-cost small
    satellites especially working together in
    international cooperative constellations
  • Security situational awareness for rapidly
    changing phenomena can be provided by
    microsatellites
  • Proliferation of microsatellites have a
    positive role to play in reducing international
    tension and avoiding conflict through a
    surveillance capability and enabling real
    participation in global issues and the
    exploration of the solar system

48
So, how to address Prof. Ben-Israel's road to
ruin? Gambling - microsatellites reduce the
risks of the unknown Technology - make us of
what we have (COTS) Women
- more women involved in space to add skills
(50 PhD students at SSC in space engineering are
women)
Change the economics of space

Security reducing tension
  • Pakistan India
  • In 2005, media in Pakistan reported that India
    was amassing troops on the border
  • Calls were made for Pakistan to respond
  • If detailed up-to-date EO images had been
    generally available to the media it would have
    clarified that no such troop concentration had
    occurred
  • China India
  • A landslide in the Zanskar Mountains, a range of
    the Himalayas, blocked the Pareechu River in its
    course from the Tibet AR of China to the Himachal
    Pradesh State of northern India
  • Initially, India challenged China for blocking
    its water supply
  • China used the Earth observation from satellites
    to identify the landslide and rapidly defuse the
    situation with its neighbour
