Flashcards in Navy Space/Geospatial Intelligence 115/205 Deck (14):
1

What are the two by-products of the sun’s fusion process that impact space systems?

Electromagnetic Radiation
Electrically Charged Particles

2

Describe Solar Wind

Electrically charged particles streaming from the sun. Can degrade radar performance and adversely affect satellites

3

Which satellite orbit is most affected by the Van Allen Radiation Belt?

Geosynchronous

4

Give an example of a common satellite in Medium Earth Orbit

GPS

5

Describe Geosynchronous Orbit and give an example of a common satellite in GSO

The satellite will have an orbital period equal to one day, Communications Satellites

6

Describe a Polar Orbit and what kind of satellites use Polar Orbit

90 Degree inclination. Has the ability to pass over the entire surface of the earth. Used extensively by imagery satellites

7

Define Apogee

The point in an orbit that is the greatest distance from the center of the earth

8

Define Perigee

The point in an orbit that is the nearest to the center of the earth

9

Describe advantages of Space-Based ISR

Provide systematic and focused coverage of an Area of Interest, sometimes without detection

10

Describe disadvantages of Space-Based ISR

Predictable overflight schedule dictated by orbit; affected by atmospheric disturbances

11

Discuss how Imagery was first recognized as an advantage in battle

During Civil War using balloons

12

What is the primary imagery system onboard CVN/LHD

Distributed Common Ground System-Navy (DCGS-N)

13

Describe the three imaging systems and type of imagery they provide

SAR: Synthetic Aperture Radar
EO: Electro-Optical, Visible Light
IR: Infrared

14

Discuss the roles and responsibilities of the following organizations:
NGA
NRO

NGA – National Geospatial Agency: Primary source of GEOINT analysis and products at the national level
NRO – National Reconnaissance Office: Designs, builds, and, with the Air Force, operates the US reconnaissance Satellites
