RabetaAlerta Brings Collision Warnings to Amazonian Rivers

rabetalerta.app Observed source

Editorial interest 84/100 Selection signal · not a rating of the site

A proposed offline collision-alert system for small riverboats, using LoRa radio, Bluetooth, and a phone’s GPS.

Landing page captured for the 2026-09-08 issue.

Field notes

The described workflow combines a small motor-powered onboard device with Bluetooth to an Android phone, using the phone’s GPS rather than dedicated navigation hardware. Boats are said to exchange positions over LoRa, while AWS services handle data only when connectivity returns. The page cites a target context of more than 50,000 regional vessels and says validation is underway in Cametá, but the extract does not show a live demo or measured alert performance.
