What is geostationary and non-geostationary satellite?

Non-geostationary (NGSO) satellites occupy a range of orbital positions (LEO satellites are located between 700km-1,500km from the Earth, MEO satellites are located at 10,000km from the Earth), and do not maintain a stationary position, but instead move in relation to the Earth’s surface.

What is mobile satellite Service explain?

Mobile satellite services (MSS) provide two-way voice and data communications to global users who are on the go or in remote locations; terminals range in size from handheld to laptop-size units. Terminals can also be mounted in a vehicle, with communications maintained while the vehicle is moving.

What are some of the basic mobile satellite services?

Most commercial voice and some data mobile satellite services are provided by systems operating in the L-band by Iridium, Inmarsat, Globalstar and Thuraya….Some companies providing commercial access:

• Avanti,
• Globalsat Group,
• Iridium Communications,
• Inmarsat,
• Telespazio,
• Thuraya,
• Vizada.

What is mobile and satellite communication?

Mobile satellite communication is rendered from the radio station (earth station) installed in ground, maritime or air mobile entities (automobile, vessel, aircraft, etc.) to the other radio station (earth station) via the artificial satellite.

What is the difference between geostationary and geosynchronous satellite?

Geostationary orbits fall in the same category as geosynchronous orbits, but it’s parked over the equator. While the geostationary orbit lies on the same plane as the equator, the geosynchronous satellites have a different inclination. This is the key difference between the two types of orbits.

What is the function of non geostationary satellite?

A communication system comprising a set of non-geostationary satellites provides communication links between ground stations and terminals, a communication link from a particular station via a satellite terminating at associated terminals in a limited geographical area including the station and providing a …

What is satellite as a service?

Satellite as a service is a modern-day data sharing technology with dependency on satellites. The focus is on the easy availability of the data to the business customers on a subscription basis. The majority of the data is made available to people with the help of satellites.

Can my phone connect to a satellite?

When you’re in the middle of nowhere and want to place a call, get info on storm warnings, or check your email, all you have to do is open the Iridium Go app on your iOS or android tablet or smartphone, flip up the device’s integrated antenna and the connection immediately converts into a satellite transmission with a …

What are satellite networks?

Satellite networks are the key to staying connected, no matter where you go. In this configuration, satellites are placed at a higher altitude — about 22,000 miles above Earth – along the equator. They are set to orbit at the same speed of Earth’s rotation, essentially keeping them stationary above us.

How are mobile services used in satellite communication?

Typically, providers of satellite mobile communications use Geostationary Orbit (GEO), Medium Earth Orbit (MEO) satellites or Low Earth Orbit (LEO) satellites to relay signals up from a handset or terminal and back down to a ground station where the signal interfaces with the public telephone system or the internet.

What is land mobile satellite service?

The Land mobile satellite service has a mobile earth station located on different types of trains and other transportation systems. This service consists of a personal location beacon terminal that acts as an earth station. This service can be used in different applications such as military applications remote and rural environments.

What is satellite communication service?

This is a communication service provided by the satellite for supporting mobile, fixed and broadband communication systems. The satellites can be geo-stationary or non geo-stationary satellites. This service consists of two earth stations: base earth station and personal earth station.

What are the different types of mobile satellite services?

The mobile satellite services are classified into the following five types: 1 Maritime mobile satellite service (MMSS) 2 Land mobile satellite service (LMSS) 3 Aeronautical mobile satellite service (AMSS) 4 Personal mobiles satellite service (PMSS) 5 Broadcast mobile satellite service (BCMSS)

How do non-GSO satellites work?

Since non-GSO satellites move across the sky during their orbit around the Earth, non-GSO operators must deploy a fleet of satellites, generally called “constellations”, to provide continuous service from these altitudes.
