It states that "user data can not be used for any non-emergency goal and only the responding 911 center will have access to the user's location during an emergency call".
The new addition builds on Apple's HELO (Hybridized Emergency Location) system that was launched in 2015, which uses cell data, GPS data and Wi-Fi access points to estimate a caller's whereabouts.
Under the new system, iPhones will send their exact location to a RapidSOS dispatcher, which will then forward the coordinates to local emergency response centers. In iOS 12, when you make an emergency 911 call, your iPhone will automatically share the location of your device with emergency responders. According to Apple's press release, Apple's HELO technology is capable of meeting and exceeding those standards today, and with the adoption of RapidSOS's protocol this fall in iOS 12, those benefits will be enjoyed by 911 call centers too.
Apple's upcoming 911 feature relies on technology from RapidSOS, a NY startup. "When every moment counts, these tools will help first responders reach our customers when they most need assistance".
Emergency calling centers, however, don't get that detailed location information from mobile 911 calls.
iPhone users will be able to automatically share their location with 911 operators in the event of an emergency.
Apple is hoping to bring more reliable location services to the emergency call system with the latest software update.
Note: iOS 12 is now only available as a developer beta, however, a public beta will likely be released sometime soon.
And, Apple says the data can only be used for emergency purposes, and only the responding 911 center will have access.
Apps like Uber and Snapchat often keep tabs on their user's location easily, but services like 911 have a harder time detecting the same information. The service is free for call centers to implement.
