The HOD (Hook-On-Device) is an ADS-B/FLARM tracking and connectivity device designed to provide position reporting and enhanced airspace awareness for uncrewed aircraft systems (UAS) and other aircraft platforms, including helicopters. With its lightweight, attachable design, the unit can be fitted to a wide variety of aircraft and enables the transmission of GNSS-derived position information to a connected Unmanned Traffic Management (UTM) environment. An integrated LTE modem and SIM card facilitate continuous data exchange, allowing operators to monitor aircraft location through a dedicated UTM application while supporting operational coordination within shared airspace environments.
In addition to transmitting its own position, the HOD receives nearby traffic information from both FLARM and ADS-B equipped aircraft and forwards this data through the LTE network to the UTM system. This provides operators with a consolidated view of relevant surrounding air traffic alongside the aircraft’s own position data. The device simultaneously broadcasts its position via FLARM, increasing visibility to other FLARM users operating nearby and supporting situational awareness among participating airspace users. By combining LTE-based connectivity, GNSS position reporting, FLARM transmission, and ADS-B/FLARM traffic reception in a compact package, the HOD supports safer and more informed UAS operations in increasingly complex airspace environments.
