Choose all of the TRUE statements.
|
|
Grouping of satellites like our GPS system uses, are called a constellation and work together in various orbits because a single satellite is not enough to complete the mission
|
|
|
MEO stands for Medium Earth Orbit and HEO stand for High Earth Orbit
|
|
|
LEO stands for Low Earth Orbit and have a limited swath area
|
|
|
Polar orbits have an inclination of 90 degrees
|
|
|
The geostationary belt is a renewable resource since satellites are always dropping out of orbit.
|
Explanation:
Detailed explanation-1: -An inclination greater than 0° and less than 90° also describes a prograde orbit.
Detailed explanation-2: -We have the following definitions: the polar orbit has an inclination angle of exactly 90 deg and the near polar orbit constellation has an inclination angle between 80 deg and 100 deg but not equal to 90 deg.
Detailed explanation-3: -With this convention, the Earth has an orbital inclination of zero degrees, and the orbital inclinations of other Solar System bodies are measured relative to this (for example, Mars has an orbital inclination of 1.85o, Mercury: 7.00o and Pluto: 17.15o).
