Low Earth Orbit Satellite phone

Low Earth Orbit Satellite phone


The satellite phones which uses the satellites from low earth orbit are called Low Earth Orbit Satellite Phones. The most and the important advantage is seamless coverage around the world regardless of any hindrances. Since the satellites are not stationary, so they need to fly the whole orbit. In this service at least one satellite is with line of sight in any of the region in the world. Two such companies were launched in the year 1990 but went into bankruptcy and now owned by new owner who bought this paying a fraction of money of the original cost.Now they are planning to launch replacement constellation of satellite supporting higher bandwidth. Data transfer seed is like 2200 bits/sec and 9600 bits/sec using satellite phone hand sets.
Geosynchronous Satellite Phone Service

Geosynchronous Satellite Phone Service

The satellite phones that use satellites in Geostationary orbit are called as Geosynchronous satellite phones. This satellites remain in a fixed position in the sky. In this system the communication for the network can be maintained using only three to four satellites.So,the launching cost is less in this arena. The satellites used for this service is too heavy like 5000 kg and expensive to build and launch. Because of the large distance from user there is a noticeable time delay in voice communication. The amount of Bandwidth is high in this case, so voice and data communication rate is higher than the low earth orbit system.
The disadvantage in Geosynchronous Satellite phone service is that in a place where there is a large sky, in this areas also some times because of no line of sight calls cannot be made because of the hill and forest. The user must need to go to a area to make a call where the line of sight is possible. But in the LEO satellite this does not happen. Though the signal is got stuck by an obstacle another satellite in the system will cover this and send signal to the satellite phone.
Below are some Geosynchronous satellite phone service company and their operation regions descriptions:
Aces: This provider is comparatively small. This provider provides voice and data communication sercives.The operating region is east Asia. The service is provided by a single satellite.
Inmarsat: This is the oldest satellite phone service provider. This company started their service in the year 1979.The main business was the installation for the ships. But after that they started a joint venture with AceS to the handheld services. This company is operating with total 12 satellites.Last one was launched in 2010.Coverage for this provider is almost all the regions in earth except the polar areas.
Thuraya: This system is based in UAE.Currently three satellites are providing coverage for this network.It covers most of the regions in euro Asia, Africa  and Australia.
MSAT: This is an American based company. This uses equipment similar to Inmarsat,Thuraya but planning to launch a hand held service in Americas like Thuraya.
Terrestar: This satellite phone service is based on North America.
ICO Global Communication: A company which just launched one satellite in the geostationary orbit but the service is not started yet.
