Introducing ACeS

3. What is a satellite ?
Satellite is any object that orbits or revolves around another object (For example : the moon is a satellite of earth, and earth is a satellite of a sun)
moon
earth
sun

4. Satellite Technology What is communications satellites?

8. What is GMPCS ?
Defined by the International Telecommunications Union (ITU) as, 'any satellite system (i.e., fixed (FSS) or mobile (MSS), global or regional, geo-stationary or non-geo-stationary, existing or planned) providing telecommunications services directly to the end-users from a constellation of satellites

9. WHY GMPCS ?
GMPCS networks will provide a unique technical solution to the limitations associated with terrestrial networks, offering messaging, voice, and data communications accessibility to anyone, anywhere, at anytime.
