ASCBC DAY 3 TEST Flashcards
What is the Space Surveillance Network (SSN)?
Detect-Track-Identify/ Characterize-Catalog and monitor man-made objects in Space.
What are two types of sensors used by the SSN?
Active- Radar
Passive- Optical (telescope/ camera)
Which Organization is the primary C2 center for the SSN?
CspOC-Combined Space Operation Center - Vandenberg, CA
What does Metric Data Provide?
Falls under SSN capabilities
Describes ‘where is it’ …describes the ELSET (a satellites position in orbit now and in the future.
Also, supplies information on cataloged objects, new domestic and foreign launches
What does SOI (Space Object Identification) data provide?
“What is it”-Determines they physical and dynamic properties (shape/ size) of an object being tracked to identify payload missions and any changes to satellite configuration.
Think the example withe ‘claw’
What are some reasons why we track satellite re-entries?
- Could be mistaken for a missile attack
- Inform appropriate agency of potential threat
- Notify nations about a re-entering object
- Assess blame and collect reparations
Define 3 categories of sensors used by the SSN
- Dedicated: Primary Mission of SSN / Owned by SPACECOM
- Collateral: Not-Primary Mission of SSN (missile defense)/ Owned by STRATCOM
- Contributing: Under contract/ provide SSN support
What is the function of Telemetry Operations?
Receive information from the satellite regarding its ‘health’.
Allows the SOC (Satellite Operations Center) to receive the state of health
ex: solar array position, battery temperature, reaction wheel speed
What is the functions of Tracking Operations?
Tracking Operations gives TEARR data and allows the tracking station to lock onto a satellite for duration of mission
What is the function of Commanding Operations?
Command the satellite to perform a task. Enter a command into a computer on Satellite to make it ‘burn for 0.35 seconds, for example
What Satellites are controlled by 1 SOPS
- GSSAP
- SBSS
What Satellites are controlled by 2 SOPS
GPS
What Satellites are controlled by 4 SOPS
DSCS (Bus Only)
WGS (Bus Only)
AEHF
What Satellites are controlled by 6 SOPS
DMPS
What is the function of the 53d Signal BN?
Where is the HQs located?
Controls the DSCS and WGS payload/ sensor
Colorado Springs, CO
Explain the function of a WSOC (Wideband Satellite Operations Center)
How many WSOCs are there?
Responsible for:
- Control Terminal Access
- Maintain Operational Databases (ODB)
- Monitor the Health and Welfare of the SHF Satellites
-5 total WSOCs
(Any WSOCs has the ability to C2 any satellite-BUS Only)
What is the relevance of SATCOM to the Army?
BLOS and data relay
List 3 types of orbits used for communications satellites
What is the primary orbit for SATCOM?
GEO, LEO, HEO
Primary: GEO
Iridium: LEO
List the 3 frequency bands that are utilized for Satellite Communications
UHF: Narrowband (300MHz-3GHz)
SHF: Wideband (3GHz-30GHz)
EHF: Protected (30GHz-300GHz)
What frequency band is most susceptible to jamming?
UHF: Narrowband
Which Frequency Band is most susceptible to atmospheric absorption, such as Earth Weather?
EHF: Protected Band
What frequency band is most susceptible to ionospheric disturbances, such as scintillation/ space weather?
UHF: Narrowband
SHF MILSATCOM satellites have jamming mitigation capabilities. List the constellation and the name of the method associated with the listed jamming mitigation capability.
DSCS: Beam Nulling
WGS: Beam Shaping
What is beam shaping?
Beam shaping is WGS satellites ability to shape the coverage area of the footprint
