In scenarios such as civil aviation airfield surveillance, general aviation operations, airport ground control, and obstacle situational awareness, a large number of aircraft, airfield service vehicles, and ground obstacles lack native ADS-B capabilities. Persistent issues—including a lack of signal reporting, "invisibility" in the operational picture, and regulatory blind spots—pose significant risks to airspace safety management and the monitoring of airfield operations.
Most traditional retrofit solutions rely on modifying onboard equipment, entailing high costs, long timelines, and complex procedures; furthermore, they require specific airframe interface integration, resulting in extremely poor versatility.To address this industry pain point, the PT300A portable ADS-B transmitter (Version 1.7) has undergone a major upgrade. With a focus on optimizing GNSS receiver performance—featuring high-precision positioning, ultra-low power consumption, and a portable, standalone design—it provides a comprehensive solution for ADS-B signal transmission across diverse scenarios, effectively resolving the usability challenges associated with traditional equipment.
Portable ADS-B Transmitter
(PT300A)
The PT300A is a compact, high-efficiency portable device designed to transmit ADS-B signals; it primarily enables ADS-B signal transmission for aircraft lacking ADS-B capabilities, airport ground vehicles, and ground-based obstacles.
