How do satellite phones work?
Unlike mobile phones which use localised phone masts to connect calls, a call made from a sat phone is sent through a satellite constellation until it reaches the nearest satellite gateway on the ground. It is then routed through traditional voice networks to reach its destination.
A call made from one satellite phone to another will be completely routed through satellite constellations to ensure that the call is not affected by any technical difficulties on the ground. This is why satellite phones are essential for communication during disasters such as earthquakes and hurricanes where traditional lines of communication can be destroyed.
Satellite phones rely on a clear view of the satellite to make a call so it is important to ensure that the phones signal is not obstructed by trees, hills, mountains, buildings or other similar structures or geographical features in close proximity.
When choosing a satellite phone you may want to consider the type of satellites that your handset will use. Iridium and Globalstar use LEO (Low Earth Orbiting) satellites whereas Inmarsat and Thuraya use geosynchronous satellites which orbit at a much higher altitude. The higher a satellite orbits the more noticeable the latency or delay in call connection and transmission.

Globalstar Completes Installation of Upgrades
Globalstar announced it has installed new hardware and software upgrades at its satellite operations and control center located in Milpitas, CA and its backup control center located in El Dorado Hills, CA. The upgrades, provided by Thales Alenia Space, are required to support the 15-year plus lifespan of the new Globalstar second-generation satellite constellation scheduled for launch beginning in September or early October of this year. The new constellation, also designed and manufactured by Thales Alenia Space, is expected to provide Globalstar customers with mobile satellite voice and data services through beyond 2025.
With less than four months to go before they begin launching the second-generation satellites they announce the completion of another major operational milestone, the installation of satellite control center upgrades. As the prime contractor of Globalstar new satellite constellation, Thales was uniquely qualified to design, develop and install the necessary hardware and software control center system enhancements. Globalstar is now testing and training control teams who will manage Globalstar's first and second-generation satellites using the newly installed in-orbit test equipment until they complete deployment of our new constellation next year.
The Globalstar Satellite Operations and Control Center (SOCC) upgrades were developed using Thales' COTS product called SCC/Open, with customizations specific to the Globalstar mission. Thales is also upgrading the Globalstar's Telemetry and Command Units (TCU) and In Orbit Test (IOT) hardware and software located at the various Globalstar gateway ground stations around the world. Combined with the SOCC improvements, these upgrades provide Globalstar with the capability to administer increased second-generation satellite constellation mission operations command, support and control with minimal expert staffing and maximum task automation.

Satellite Phones vs Cell Phones
What is the difference between a satellite phone and a cell phone? Cell phones rely on terrestrial networks to complete a call whereas satellite phones rely on orbiting satellites – the satellite is the equivalent of a cell phone mast. This means that sat phones are ideal for individuals traveling in remote locations where there is no cell phone coverage. It also means that satellite phones are essential in case of emergency such as a hurricane or earthquake – often the local cell phone infrastructure is destroyed which makes calls by cell phone impossible.
Although call costs are more expensive using a satellite phone when you are in an area with no traditional communication methods, sat phones are vital. As this map from GSM World shows, there are still vast regions of the world that aren’t covered by GSM networks. Compare this with the Iridium satellite phone network which provides global coverage and you can see how useful satellite phones are.
Another difference between satellite phones and cell phones are the handsets used. Satellite phones have a built in extendable antenna which allows the phone to pick up a satellite signal. Apart from the extendable antenna the handsets are now very similar in size and weight to cell phones making them very easy to carry when travelling.
It is possible to combine the advantages of GSM and satellite networks in one handset. Thuraya SIM cards allow you to roam on compatible GSM networks when in their coverage area. Even better, the Thuraya SG-2520 functions with both a Thuraya SIM card and GSM SIM card with no phone unlocking required. This means that when you are in a GSM coverage area you can use a local SIM card reducing call costs and meaning you only need to carry one handset.
Satellite phones and cell phones both have their advantages but for communication in remote locations a sat phone is the best option.
