al satellites to distinguish them from natural satellites such as the Moon.There are three basic categories of non-military satellite services:
1.Fixed Satellite Service

2.Mobile Satellite Systems
Mobile satellite systems help connect remote regions, vehicles, ships and aircraft to other parts of the world and/or other mobile or stationary communications units, in addition to serving as navigation systems
3.Scientific Research Satellite (commercial and noncommercial)
Scientific research satellites provide us with meteorological information, land survey data (e.g., remote sensing), and other different scientific research applications such as earth science, marine science, and atmospheric research.
There are many different types of satellites
