Quick Answer
A group expedition should have at least one satellite phone per 10 people to ensure reliable communication.
Satellite Phone Requirements
When planning a group expedition, it’s essential to determine the number of satellite phones required. This calculation depends on several factors, including the size of the group, the terrain, and the level of risk. As a general rule, we recommend one satellite phone per 10 people to ensure reliable communication.
Choosing the Right Satellite Phone
Not all satellite phones are created equal, and for a group expedition, you’ll want to choose a device that’s rugged, reliable, and has a long battery life. Some popular options include the Iridium 9555, the Globalstar GSP-1700, and the Inmarsat IsatPhone 2. These devices typically have a battery life of 8-12 hours and can withstand extreme temperatures and humidity.
Operating Frequency and Coverage
When using satellite phones, it’s essential to consider the operating frequency and coverage area. Iridium satellites, for example, offer global coverage, while Inmarsat offers coverage in the Northern and Southern hemispheres. Globalstar, on the other hand, offers coverage in the Northern hemisphere. Be sure to choose a device that suits your expedition’s location and requirements.
