Q18
Conic projections
Answer: Projection: preserves directions and areas in limited areas. Distorts distances
Q19
Conical Projection
Answer: Projection to use when broad in East-west (eg the US)
Q20
Projection to use when broad in North-south (eg Africa) Transverse-case cylindrical projection.

, Q21
GPS Satellites
Answer: There are 24 core in medium earth orbit (~12,600 miles). Orbital
Q22
GPS Constellation Satellites in the
Answer: are arranged into six equally-spaced orbital planes surrounding the Earth.
Each plane contains four "slots" occupied by baseline satellites. This 24-slot
arrangement ensures users can view at least four satellites from virtually any point on
the planet.
