A drone spotting app

A drone spotting app used in Ukraine

As Ukraine enters the second year of the full-scale Russian invasion, we hear about A drone spotting app through which citizens can help alert defense authorities of air attacks.

This program is available NOW On Demand on the Digital Planet Page and is available now until Wednesday the 8th of March. It will also be broadcast on Sunday the 5th of March in Phuket on 91.5 FM and 102.5 FM and Online via the Internet radio portals.

To help prevent future attacks, the country’s Air Defence Forces want people to use their phones to report hostile airborne objects.

Installing A drone spotting app

Simply install an app, point your handset at the object, select the category – say a drone or a missile – and press the button.

It means observers on the ground can pick up objects flying too low for radar detection.

Gareth speaks to one of the app’s developers, Gennadiy Suldin of the tech start-up NGO Technari.
