Vigilant Aerospace Systems has launched the FlightHorizon™ ALERT service, an airspace awareness and alerting system for general aviation airports, critical infrastructure and any facility that needs better awareness of nearby aircraft and drones.
“The new service is designed to be easy to install, easy to use, and affordable for smaller facilities and general aviation airports.,” said the company in a news release. “The system uses a single receiver box to detect both aircraft and drones and display them in a 3D moving map on the web. The system also sends text messages or an email when an aircraft or drone is nearby. The alert includes a link to an instant replay of the aircraft on a 3D map. All air traffic is logged and flight visualization, reporting and analysis tools are provided in the web application. The service is designed to give smaller airports and facilities practical airspace awareness without adding a complex monitoring burden.”
Kraettli L. Epperson, CEO of Vigilant Aerospace Systems, said: “Many airports and facilities need better low-altitude airspace awareness, but they do not need another complex system that requires constant monitoring. FlightHorizon ALERT is designed to make aircraft and drone activity easier to detect, track and analyze with a managed service that can be deployed quickly.”
FlightHorizon ALERT gives airport managers or facility personnel a simple way to see what is flying nearby on a web map, receive automatic text alerts and review what happened after the alert, said the company. The system is especially suited for monitoring low-altitude airspace around runways, approach surfaces and zones, ramps, perimeters, facility or campus restricted areas, industrial sites and other locations where unexpected aircraft or drone activity may require attention, says Vigilant.
FlightHorizon ALERT is an online service for a single monthly fee that includes the hardware required to monitor aircraft and drones at any location. Leveraging software developed by Vigilant for the US Air Force and using two licensed NASA patents, the new service uses low-cost technology to provide a simple, all-in-one detection, tracking, alerting and logging system, says Vigilant. Once plugged into power and internet, the system begins displaying air traffic in real time on aweb browser and phone, logging the air traffic and sending alerts about nearby flights via text message and email.
The system works by tracking and logging aircraft transponders (ADS-B) and drone beacons (Remote ID), which are required on all drones flown in the United States weighing more than 250 grams.
