Dates Active
2013 - Current

The RT-600-L, a specialized variant of the acclaimed RT-600/SAR-DF 517 series, is an advanced radio direction finder system meticulously crafted for airborne applications with a focus on Law Enforcement. Expertly engineered by RHOTHETA, this model offers comprehensive signal detection capabilities across a plethora of frequencies, encompassing VHF, UHF, COSPAS-SARSAT, and maritime channels. The ability to broaden its frequency spectrum to an impressive 470 MHz ensures unparalleled detection and indication capacities, making it indispensable for airborne law enforcement missions.

Exclusively designed to cater to the stringent requirements of US Law Enforcement, the RT-600-L incorporates features that position it leagues ahead of standard direction finders. One of its standout functionalities is the support for the LoJack Stolen Vehicle Recovery Technology. Not only does it provide pinpoint directional guidance to targets, but it also displays LoJack reply codes, making vehicle recovery swifter and more efficient. Additionally, the RT-600-L tracks a diverse array of beacons, from Electronic Tracking System (ETS) beacons to Personal Locator Beacons (PLB), ensuring comprehensive surveillance and detection capabilities.

With a stellar track record in missions across the globe, the RT-600 series, and by extension, the RT-600-L, is a testament to RHOTHETA's commitment to reliability and performance. Be it the harsh terrains of SAR missions or the complex demands of Law Enforcement operations, the RT-600-L consistently delivers precise direction-finding, adeptly demodulating and decoding a vast range of transmissions, from AM, FM, PM, to CW signals. It's not just a tool; it's an assurance of excellence in airborne law enforcement.

From Patrol to Pursuit: LoJack Capable 

The RT-600-L showcases an advanced focus on LoJack beacon tracking, pivotal for Stolen Vehicle Recovery Systems (SVRS). Upon startup, the system immediately engages its LoJack Scan Mode, swiftly detecting valid VLU (Vehicle Location Unit) codes. To enhance precision, users have the ability to input VLU codes manually, mute specific unwanted signals, or seamlessly transition to DF Mode with new detections.

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, 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.
