How it works

ELS delivers fast and accurate location information.

With multiple location signals for greater accuracy.

In many countries today, emergency call centers only receive cell-based location information. In other countries, emergency location is estimated using GPS—falling back to cell tower triangulation if GPS is unavailable.

Yet cell-based location radii are often kilometers wide. And GPS performance tends to be poor indoors, underground or in city centers with tall buildings.

With ELS, the device automatically sends location information when a user contacts a configured emergency number. This happens via a location request made to the Android Fused Location Provider. FLP allows us to derive a more accurate location as quickly as possible, using a variety of location signals. And the best part: it works both indoors and outdoors.

Enhance your emergency response with ELS.

Google partners with mobile network operators, public safety vendors and government agencies responsible for public safety to deploy ELS.

ELS location information is sent only when the user contacts your region’s emergency number. Location is computed locally, and sent directly from the Android device to a partner endpoint. Google does not view the location sent to the endpoint.

  1. The partner manages the endpoint.

    Each ELS partner is responsible for setting up, configuring and maintaining an ELS endpoint that can receive ELS location information whenever a user contacts an emergency number.

  2. The user initiates an emergency call.

    The user calls or texts a national emergency number using an Android device.

  3. ELS uses FLP to determine the user's location.

    The Android device automatically activates ELS. ELS uses the Fused Location Provider (FLP) to fuse location signals from cell towers, GPS, Wi-Fi and sensors on the phone to compute accurate location data, whether the caller is indoors or outdoors.

  4. Location information is sent to the partner.

    The user’s location is directly sent to emergency services through the partner’s endpoint, per partner-specified configuration (e.g., MCC/MNC). Google does not view the location sent to the endpoint.

Case study: United Kingdom

ELS can be up to 3000x more accurate than cell tower triangulation.1

In the UK, a live test found that public safety providers were only able to accurately target within a 3 kilometer radius using existing cell-based location information.

Using ELS, more than half of those same public safety providers were able to report locations within >20m accuracy.
