Term | Definition |
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 |

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 |
