The RHOTHETA RT-600 A, also known as the STANDARD version, stands as a testament to advanced radio direction finding technology crafted for airborne applications. Primarily designed for search and rescue missions, this system offers expansive coverage of emergency signals across various frequencies. From VHF to UHF, marine channel 16, and every COSPAS/SARSAT channel, the RT-600 A ensures no distress call goes unnoticed.

Distinguished by its precision and efficiency, the device capitalizes on its patented wideband antenna and revolutionary bearing analysis algorithms. This combination delivers quick, steady, and reliable information to the user. For a more in-depth perspective, consider the Direction Finder (DF) mode. Here, depending on the type of signal received, operators can view a gamut of information, ranging from basic bearings from analog sweep-tones to intricate details from digital signals such as COSPAS-SARSAT. The unit further impresses with its ability to scan the entire COSPAS-SARSAT sub-band in less than 400 milliseconds, ensuring the detection of a signal within a single COSPAS-SARSAT repetition cycle.

Durability is another hallmark of the RT-600 A. Designed explicitly for the rigors of airborne operations, it can withstand harsh conditions, making it a reliable companion for any search and rescue mission. With its compact design, it remains suitable for both manned and unmanned aircraft, ensuring adaptability across a range of aerial platforms.

The RT-600 easily decodes of incoming  COSPAS-SARSAT beacons messages. Users can track beacons in VHF by switching to 121.500 MHz while in COSPAS-SARSAT DF Mode, and if no valid signal is received, they can switch back to the last active COSPAS-SARSAT channel at 406 MHz. In COSPAS-SARSAT Scan Mode, the RT-600 scans manually selectable channels and stops at the received frequency, allowing for fast scanning of the complete sub-band and detection of receivable signals within one repetition cycle.

Seamless Integration with Mission Management System

The RT-600 radio direction finder can be integrated with augmented reality mapping systems for airborne law enforcement, search and rescue, and aerial firefighting missions. Real-time direction-finding information is exchanged for the tracking and locating of various transmitters like LoJack, ETS, medical beacons, and cash/asset recovery tags. This integration empowers flight crews with improved surveillance, intelligence gathering, and operational efficiency by visualizing and monitoring tracked signals in real time for better target identification and pursuit management.

NVG Option Available

The RT-600 offers an NVG (Night Vision Goggles) option that enhances operational capabilities for pilots in low-light or night-time conditions. With this option, pilots can effectively utilize the display control unit while wearing their night vision goggles. Pilots maintain clear visibility of the display and can easily access and interact with the system's controls and information, enabling safe and efficient operations even in dark environments. The NVG option provides an enhanced user experience and maximizes situational awareness during night flights, contributing to overall mission success and pilot safety.
