How Apple Emergency Services Work?

Apple has introduced two new emergency services with iPhone 14 & Pro. Emergency SOS via satellite & crash Detection calls for help when you can’t. Here are the complete details of both the services provided by Apple.

Emergency SOS via satellite

Peace of mind when you’re off the grid. If you don’t have cell service or Wi‑Fi, iPhone lets you text emergency services over satellite.

How on earth do you communicate via satellite?

Satellites are moving targets with low bandwidth. It can take minutes for messages to get through. Since every second counts, iPhone front-loads a few questions to assess your situation — just tap to respond. Then it shows you where to point to connect to a satellite. Once connected, iPhone automatically sends your answers, location, Medical ID (if set up), and battery level to a dispatcher.

You must be outdoors with a clear view of the sky. Since satellites are moving rapidly through space, iPhone will show you where to point to maintain your connection — and avoid obstructions such as mountains and heavy foliage.

Texting via satellite takes time. In ideal conditions, you can send a message in less than 15 seconds. Under light foliage, it can take more than a minute.

Emergency SOS via satellite is included for free with iPhone 14 & Pro for two years.

An infrastructure of innovation.

Apple-designed components and software allow iPhone 14 & Pro antennas to connect to satellite frequencies. And since bandwidth is low, they also created a compression algorithm that makes text messages three times smaller, speeding up communication.

On the ground, they route your text message through a complex infrastructure to emergency service providers. Only some accept texts. For those that don’t, they’ve set up emergency relay centers with Apple-trained specialists who call for help on your behalf.

Let friends know how remote you go.

If you’re on an adventure without cell service, you can now use Find My to share your location via satellite, so friends and family know where you are.

Emergency Crash Detection

iPhone 14 & Pro can detect a severe car crash, then call 911 and notify your emergency contacts.

How iPhone feels, hears, and measures a crash.

  1. Sudden speed shifts
    • A new high g-force accelerometer senses extreme accelerations or decelerations up to 256 Gs.
  2. Abrupt changes in direction
    • A high dynamic range gyroscope monitors drastic changes in a car’s orientation.
  3. Laboratory crash tests
    • They developed advanced motion algorithms by performing head-on, rear-end, side-impact, and rollover crash tests.
  4. Cabin pressure changes
    • The barometer can detect pressure changes caused by deploying airbags.
  5. Loud sound levels of impact
    • While you’re driving, the microphone identifies the extreme sound levels of a collision. For privacy, all processing is done on your iPhone.
  6. Real-world crash data
    • They used public crash data from accidents to make Crash Detection as accurate as possible. 1 million hours of real‑world driving, and crash data helps iPhone recognize accidents
