Vorpal is the developer of VigilAir, a non-transmitting RF-based drone location and mitigation solution. VigilAir provides long-range, highly accurate drone situational awareness and is integrated with advanced counter-UAS and mitigation capabilities. The solution helps protect airspace safety, enhances perimeter security, and supports the complex operation of drones within the UTM framework. VigilAir detects, geolocates, and tracks drones by passive RF geolocation of their command-and-control and data transmissions, providing aerial situational awareness with exceptional clarity. In addition, VigilAir's advanced counter-UAS capabilities include drone operator geolocation and tracking, telemetry data extraction, drone identification friend or foe (IFF), and drone neutralization (drone soft takeover).
