Understanding Satellite Communication Networks
Satellite communicators rely on different satellite networks, each with unique characteristics that affect coverage, message delivery speed, and reliability:
Iridium Network
The Iridium constellation consists of 66 low-Earth orbit satellites providing true global coverage, including polar regions. Iridium satellites offer the most reliable worldwide coverage and fastest message delivery, typically within 2-10 minutes. This network is used by Garmin inReach devices and is considered the gold standard for emergency communication.
Globalstar Network
Globalstar operates 24 satellites in low-Earth orbit with coverage spanning most populated areas of the Earth, excluding polar regions and parts of Africa and Asia. Message delivery can be slower than Iridium, sometimes taking 20+ minutes in challenging terrain. SPOT devices use the Globalstar network.
Cospas-Sarsat
This international search and rescue satellite system is designed specifically for emergency beacons (EPIRBs and PLBs). It provides global coverage and directly alerts rescue coordination centers, but offers no two-way communication capabilities.
