TermDefinition
Space Force Enhancement ISR; missile warning, environmental monitoring, satellite communications, space- based positioning, navigation and timing
Space Support space life, satellite, and reconstitution operations of space forces
Space Control Protect space capabilities and deny freedom of space for the adversary
Space Force Application Attacks against terrestrial- based targets
How does the SUN affect communications biggest effect on space environment Electromagnetic radiation, electrically charged particles
How does SOLAR WIND affect comms? travels at one million mph, carrying various particles from the sun
How does SOLAR CYCLE affects comms? solar activity cyclic in nature, 11 year cycle
How does VAN ALLEN RADIATION BELTS affect comms? belt of charged particles held in place around the Earth by the Earth's magnetic field
How does ATMOSPHERIC DRAG affect comms? low orbiting objects, below 1000 km, are slowed by the atmosphere, resulting in the space craft not being where it is expected and to reduce the spacecraft's altitude
Low Earth Orbit 150- 800 miles above the Earth's surface
Medium Earth Orbit 10,8000 miles 12 hour period
Highly Elliptical Orbit satellite slows down at apogee and speeds up at perigee
Geosynchronous Orbit 19,300 miles altitude remains over the same area of the Earth
Polar Orbit inclination of 90 degrees
Apogee farthest point of orbit from the center of the Earth
Perigee Closest point of orbit of the Earth
3 Main Space Launch Facilities in US Vandenberg Air Force Base (VAFB), California Kennedy Space Center, Florida Wallops Island, VA
Navy UHF Follow-on Links ships, mobile units, and shore sights together
Defense Satellite Communications System High capacity SHF satellite
Systems that utilize DSCS Global Command and Control System Joint Deployable Intelligence Support System Joint Worldwide Intelligence Communications System Contingency TACS Automated Planning System Secure Telephone
GBS Provides high data rate broadcast of data and video information products to military tactical terminals
WGS Wideband Global SATCOM (WGS) provides flexible, high- capacity communications for the Nation's war fighters through real world operationalization
Global Positioning System (GPS) satellites broadcast navigation information on a continuous basis SPS- unencrypted civilian positioning PPS- military positioning
Advantages of space- based ISR Primarily used to provide systematic focused coverage of an area of interest,
Disadvantages of space- based ISR predictable over- flight schedule, atmospheric disturbance
Space Situational Awareness (SSA) Characterizing the space capabilities operating within the terrestrial environment and the space domain
Astrometry natural science that deals with the study of celestial objects
Earth Orientation Parameters the Earth's rotation is not even
Role of precise time in the following: GPS, accurate time and location with the assistance of atomic clocks
Role of precise time in GEO- LOCATION greater emphasis on determining a meaningful location rather than just a set of geographic coordinates
Role of precise time in NETWORK SYNCHRONIZATION crucial to a variety of economic activities around the world
