Emergency location - What you should know about HTML5 Geolocation

EENA Technical document for public safety professionals.

Emergency services need location information – it is a simple fact. And yet, in most cases, the information they receive is not accurate enough.

Problematic emergency location has many implications, from lives lost to high operational costs for emergency services and authorities.

One of the solutions to this issue is HTML5 Geolocation, a technique used by some emergency services to request accurate location from a caller’s smartphone.


How does it work?

When a citizen dials an emergency number, the most appropriate public safety anwering point (PSAP) receives the call. If the network location information provided to the PSAP by the Mobile Network Operator is unavailable or inaccurate, the PSAP can send an SMS to the caller with an embedded web link. The caller then opens the SMS and clicks on the link, sending the GNSS-based location to the PSAP.
