2SmallSats 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
3Overview
- What are Small Satellites
- Introduction to Space _at_ Surrey
- Current small satellite capabilities
- Where is it leading?
- Implications for Security from Space
4What are Small Satellites?
Mass Cost Time Large 1000kg 200M 10yrs
5What 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
6How 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

46Conclusions 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
47Conclusions 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
48So, 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

50Security 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
