How Does GPS SOS Work

GPS SOS

The most common way to communicate with help when you’re out in the wild is through a two-way satellite messenger, such as an InReach or SPOT device. These devices work with a private company called GEOS to initiate and coordinate rescues worldwide.

These handheld devices use either the Iridium or Globalstar commercial satellite networks rather than the military network used by PLBs (this is why they cost a bit more). The advantage of these devices is that they can also send text messages to your contacts, update your location on a regular basis, and link to your social media accounts.

You can activate your emergency SOS via the smartphone app or physically by pressing the SOS button on the device. Both will trigger a message to GEOS which then routes it through the International Emergency Response Coordination Centre (IERCC) using the Iridium satellite network.

GEOS monitors SOS calls round the clock and works to connect you with local search and rescue teams and your friends and family.

They’ll even alert the authorities or a user-selected individual of your exact location including directions.
