Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

is a LEO system utilizing a 66 satellite constellation orbiting approximately 480 miles above Earth’s surface

A	Iridium
B	Telstar I
C	Molinya
D	None of the above

Explanation:

Detailed explanation-1: -Motorola’s satellite-based mobile-telephone system (Iridium) is a LEO system utilizing a 66-satellite constellation orbiting approximately 480 miles (around 770 Km) above Earth’s surface. simpler system design (spin around the Earth between 2 and 12 hours) ➢ MEO can cover larger populations with fewer handovers.

Detailed explanation-2: -Mega satellite constellations in the low Earth orbit belong to Starlink, OneWeb, Iridium, GlobalStar, RapidEye, and other operators.

Detailed explanation-3: -Size: The host satellite platform measures 70cm x 70cm x 70cm and both ELO 1 and ELO 2’s maximum antenna dimension is 50cm.

Detailed explanation-4: -Unlike geosynchronous satellite, satellites in LEO have a small field of view and so can observe and communicate with only a fraction of the Earth at a time. This means that a network (or “constellation") of satellites is required to provide continuous coverage.
