Q47.
How often should equator-crossings ephemeris
data be updated for the AN/SMQ-11?
Q48.
Where does ephemeris data for DMSP satellites
originate?
SUMMARY
In this chapter we have discussed the various
applications of satellite data and some basic terms used
to discuss satellite orbits and satellite imagery
acquisition. We have identified several types of
environmental satellites and explained the advantages
and disadvantages of each. We have also discussed the
use of various types of satellite imagery, and also
introduced you to some basic imagery enhancement
techniques. We described several methods used to
acquire satellite imagery, and the basic equipment used
at Navy and Marine Corps shore stations and aboard
ships to receive imagery. We also discussed some of the
bulletins that provide the orbital data required as input
for satellite receiver-processors.
