9 SSA Flashcards
What is SSA and how is it defined in JDP 0-30 2nd Edition?
Space Situational Awareness
“Space situational awareness Underpins all other space roles and provides details of the hazards, risks and threats to the domain”
To have operationally relevant SSA we need to develop….
…an ability to characterise activity to inform UNDERSTAND of adversary action in terms of both capability and intent.
Orbital objects can be categorised in 2 categorises, these are:
Passive
Active
What is the difference between Passive and Active orbital objects
Passive
- Non-manoeuvrable
- Debris
- Dynamic situation
Active
- Manoeuvrable
- Cooperative
- Non-cooperative
- Adversarial
What does SSN stand for?
Space Surveillance Network
What 2 types of sensors are in the Space Surveillance Network (SSN)?
Radar + Optical sensors
The 3 Space Surveillance Network (SSN) sensor missions are:
Dedicated sensor
Collateral sensor
Contributing sensor
Is the RAF Fylingdales radar a ‘dedicated” sensor in the SSN network?
No - it is a ‘contributing’ sensor
How can you get a higher resolution pseudo image with Wideband SOI (Space Object Identification)?
By using a higher frequency setting
What are the 2 variables plotted on a narrowband SOI (Space Object Identification) data capture that are used to provide information on a satellite?
Radar strength vs time
What are the 3 main challenges of SSA?
Characterisation
Capacity and Tasking
Understand and Extrapolate
What is the Kessler Syndrome?
Chain reaction of collisions on orbital objects
Potentially rendering certain orbits unusable
