iOS 18 Satellite Location Sharing in Find My

Apple's iOS 18 expands off-grid connectivity by allowing users outside of cellular and Wi-Fi coverage to update their location using satellite networks. This guide explains how satellite location sharing operates in the Find My app, how users establish a connection, and what friends and family see when an update is delivered.

Requirements and Availability

To use satellite location sharing in Find My, you must have an iPhone 14 or newer running iOS 18. You must also be outdoors with a clear view of the sky and horizon, away from tall buildings or dense tree cover that can obstruct satellite signals. Additionally, you must already be sharing your location with the chosen contacts before losing cellular reception.

Establishing a Satellite Connection

When your iPhone detects that you are completely out of terrestrial network range (cellular and Wi-Fi), satellite connectivity becomes available:

  1. Open the Find My app and select the Me tab.
  2. Under the "My Location via Satellite" section, select Send My Location.
  3. Follow the on-screen prompts. iOS displays an interactive directional guide instructing you to turn left or right to point your iPhone directly at the nearest orbiting satellite.
  4. Maintain that alignment until the transmission completes, which typically takes between 15 and 30 seconds depending on signal strength.

How Updates Are Transmitted

Unlike standard cellular tracking, satellite location sharing does not provide continuous, real-time tracking in the background. Because satellite connections require line-of-sight and consume significant device resources, updates are transactional:

  • Manual Transmissions: You must manually send your location whenever you wish to provide an update.
  • Frequency Limits: Apple allows you to send an updated location pin approximately once every 15 minutes.
  • Encrypted Packets: The location data is compressed into minimal data packets and sent securely to satellite ground stations, which then route the data to Apple's servers.

What Friends and Family See

When your contacts open the Find My app, your location is updated on their map with specific indicators:

  • Satellite Badge: A small satellite icon appears next to your name and avatar, indicating the coordinate was captured off-grid.
  • Timestamp: A clear label (such as "Location via Satellite • 12m ago") shows the exact time the satellite transmission was completed.
  • Static Location Pin: Because there is no persistent data stream, your contact sees the static pin from your last transmission until you manually aim at a satellite and send a new one.
