Q 2.16 How can we categories different types of satellites?
Satellites may be categorized according to their orbit, weight, function, or payload.
By orbit

By function
Communication, Broadcast, Navigation, Remote Sensing (Earth Observation, Weather, Meteorology, etc.), Military, Scientific, Research and Development, Inter-planetary, etc.By payload
Communication
Global beam, Spot-beam, Transparent, Processing, High throughput, L-band, X-band, Ku-band or Ka-band satellite, Mobile services, Fixed services
Direct broadcast satellites
Television, Radio, Multi-media, Distribution
Remote sensing satellites may be categorized based on the remote-sensing probe (sensor- optical, microwave, infrared, multi-spectral, etc.); by spatial resolution; by application (e.g. Earth resource).
Military satellites
communication, surveillance, early warning, nuclear detector, etc.
Navigation
Global, Regional, Satellite Based Augmentation
