Iridium Satellite Phones

Iridium Satellites

Iridium Satellite Phone Logo

Iridium offer a totally global network using a network of 66 low orbiting satellites, this keeps the call quality high and the delay on the line low. With an Iridium satellite phone you can place calls from the middle of an ocean and the network routes the call via the Iridium satellite network to the nearest ground station (unlike Globalstar which can only be used "near" land).

Note: There is a lot of misinformation about the actual bandwidth of a normal Iridium data connection

A wide variety of Iridium phones are available including portable phones such as the Iridium 9555. Fixed satellite phones are also avaialble such as the Iridium 9522-P and some larger units such as the Eurocom / Skanti / Sailor fixed Iridium phones

Iridium Coverage

Iridium Satellite Network Coverage graphic

As you can see from the animated graphic, the orbiting nature of the Iridium satellites means there is global coverage. However, Iridium state that the system cannot be used in a number of countries including Poland, North Korea, Northern Sri Lanka. However, opinion varies as to how well this is enforced in practice.

Iridium satellites pass overhead approximately every 7 minutes and the network automatically hands off to the next nearest satellite - so line drops should be rare as long as you have a strong signal and a clear view of the sky. At any one time it should be possible for the phone to "see" a number of iridium satellites.

Iridium Accessories

Serial to USB Adaptor

Serial to USB adaptor

The Iridium datakit is supplied with a "Serial" connector. Most laptops sold these days do not have this connector and so an adaptor to convert to USB will be required.

Our adaptors are well tested and have proved very reliable and easy to configure (always a nice feature when you are 1,000 miles from the nearest computer shop). You can also easily use more than one adaptor if required (for example if you need a second for a GPS unit, or an SSB weather system, etc)
