The Rhotheta RT-600 is a high-performance airborne direction finder designed specifically for search-and-rescue (SAR), law enforcement, and special mission operations. Engineered with cutting-edge digital signal processing and compact, lightweight construction, the RT-600 offers precise bearing information and real-time signal tracking across a broad range of distress frequencies. Its intuitive interface, compatibility with COSPAS-SARSAT, AIS, and emergency beacons, and seamless integration with modern avionics make it an ideal solution for fast, accurate location of distress signals in critical missions.

COSPAS-SARSAT Ready
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
Built for tactical missions, the DF-935 integrates smoothly with Personnel Locator Systems (PLS) and survival radios such as the AN/PRC-112 and URX3000, delivering both range and bearing data. It supports Search and Rescue (SAR) and Combat SAR (CSAR) modes, providing high situational flexibility. With discrete outputs for OTPI (on-top position indication) and distress alerts, the system ensures rapid and precise reporting under pressure. Designed to military environmental standards (DO-160C and DEF-STAN), it offers waterproofing, vibration/shock resistance, and EMI protection. Housed in a compact form factor, the antenna uses a modified annular slot design with a cardioid pattern, providing accurate DF readings—better than 5° RMS depending on installation conditions.
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.
