Our services

Communication has never been as important as it is today. Developping it in Africa is essential in order to compensate the lack of GSM equipment in some isolated regions. Satellite communications are a real added value to allow them to communicate locally or internationnaly. With a limited investment, they will be able to communicate and also to guarantee their security.

Each satellite network has its own specificities. Let’s describe the most suitables for Africa.

Let’s begin with Iridium, the only worldwide satellite network covering each point of the Earth Surface including the poles. Iridium constellation consists of 66 satellites in low orbits operating at 780km only from the Earth. Portable and easy to use Iridium solutions are perfect for people needing mobility and fast deployment. The terrestrial, maritime or vehicle transport offer a wide range of current telecommunication satellite services.

Iridium’s coverage

Inmarsat the International Maritime Satellite, is a pioneer in the communications in maritime, terrestrial and aeronautic fields and a key player in a major part of the globe with its 11 geostationary satellites. Proven, reliable and multi-skilled Inmarsat network allows all types of services from telephony to high-speed data transmission.

Inmarsat’s coverage

In Africa, we can also suggest to use Thuraya.
It is a regional satellite network composed of 2 geostationary satellites.
It has been designed to complete the existing GSM networks and spread its use beyond areas not usually covered. Thuraya offers reliable voice services, data transmission, fax, SMS and GPS, thanks to mono or multimode portable handsets, satellite and GSM. Thuraya coverage area includes 140 countries in Asia, Africa, Australia, Middle East and Europe. The countries which are not concerned by the coverage in Africa are in the south. You can find a map of the countries on our website :

Each network developps the same typology of devices which are satellite phones, high data transmission modems and tracking products.

Thuraya’s coverage

Let’s focus on the satellite phones for the moment. The handheld devices are easy to use, light and with a reasonnable size. For Iridium, there are 9555 and Extreme 9575. The second one is the evolution of the first one. Indeed, it integrates GPS and SOS button in telephony mode.

On Inmarsat’s side, we can find the IsatPhone2. With a high quality voice, it has taken over the IsatPhone Pro. Moreover it is cheaper than Iridium devices. If you choose the IsatPhone 2 be careful of using it in an aera which is covered by Inmarsat’s satellites and to point the antenna on the right direction. Mountains can also be barriers to get the signal.

For the regional one, Thuraya, 2 range of satellite phones are recommended, the XT-Lite and XT-Pro. The first one is a low-cost handheld with simple options: calls and texts, however you can’t do data. And the evolved one « XT-Pro » offered navigation systems (GPS, BeiDou and Glonass), SOS button, phonie, fax, Internet and SMS by satellites.

I would like to bring your attention on industries’s needs, it could be interesting to equipped them with modems in order to get access to communications to numerous people. Dans les zones reculées, les téléphones satellites peuvent aider à garder le contact mais aussi sauver des vies. En effet, il faut pouvoir être joignable. In remote areas, satellite phones can help you keeping in contact with your employees, colleagues, warning emergencies services if there is any problem to solve.
