How SOS Devices Work

SOS devices are designed to send emergency alerts to the right people, no matter where you are in the world. They work by sending a signal to a satellite network, which then forwards the message to a response coordination center.

The signal is picked up by a satellite and/or aircraft, and an alert message is relayed to the nearest Local User Terminal (LUT). The LUT calculates your position and sends the data to the Mission Control Centre (MCC), which then initiates a class II rescue operation.

Satellites keep moving, so even if your message doesn't send immediately, one will eventually come into sight of your location and the message will send. It's essential to have a clear view of the sky for the device to work effectively.

In some cases, you may be able to communicate in more detail with the response center via messaging on your phone or on the device directly. This depends on the specific device you have.

Here's a breakdown of the typical steps involved in an SOS alert:

  • SOS button is pressed
  • Signal is sent to a satellite network
  • Message is forwarded to a response coordination center
  • Class II rescue operation is initiated

How They Work

SOS devices are designed to send emergency signals to the right people, but have you ever wondered how they work? They use satellites to communicate.

Once activated, the signal is picked up by satellite and/or aircraft. An alert message is relayed to the nearest Local User Terminal (LUT), which calculates the beacon's position and sends the data to the Mission Control Centre (MCC).

The MCC then sends the information to the RCCNZ, which initiates a class II rescue operation. This process happens quickly, but it's essential to keep the device on and in the same location until help arrives.

If you're in an area with heavy foliage or a gorge, the device may not work as quickly due to the obscured sky view. But don't worry, satellites keep moving, and the message will send within a few minutes.

Here's a list of how SOS devices work in different scenarios:

  • Clear view of the sky: Devices work quickly and efficiently.
  • Heavy foliage or gorges: Devices may take a few minutes to send the message due to the obscured sky view.
  • No signal: Devices can still send messages via satellite.

In some cases, you may be able to communicate with the emergency response centre via messaging on your phone or directly on the device. This is dependent on the device you have and the features it offers.

Networks Used by Services and Their Availability

PLBs rely on government-backed SARSAT satellites.

Iridium and Globalstar are the private satellite networks used by satellite messengers.

Iridium has the strongest network, making it usable almost anywhere in the world.

Globalstar's signal strength can be inconsistent outside of the US and Europe.

For round-the-world travelers, Iridium is the recommended choice due to its reliability.

Device Costs and Options

Device costs can be a bit confusing, but I'll break it down for you. The one-off fee to purchase an emergency satellite device can range from £100 to £300.

Some devices may also require an activation fee, which is typically around £15 to £20. You'll also need to consider the subscription plan, which can range from £12 to £50 per month, or £14.99 to £64.99 per month, depending on the device and plan.

There are different types of subscription plans available, including yearly and monthly options. Some devices may also offer free suspension or pay-as-you-go plans.

Here's a rough idea of what you might expect to pay:

Keep in mind that the costs can vary depending on the device and plan you choose.
