Product Description

The TCI Model 720A is a high-performance radio direction finder that can be integrated into maritime vessel traffic systems (VTS) or interference detection systems for search and rescue operations and radio band protection applications. Model 720A systems can also be used individually or networked together on land or on a vessel to identify the LOB or source location of distress signals or other RF transmissions. A compact member of TCI’s 700 series of field-proven Spectrum Monitoring Systems (SMS), the 720A provides an accurate, real-time solution for unattended monitoring and instantaneous identification of the source of radio transmissions for applications such as: Vessel tracking systems (VTS), Port management, Maritime border protection, Search and rescue (SAR) for aeronautical and maritime services (121.5 MHz, 156.8 MHz, optional 243.0 MHz & 406.25 MHz), Interference detection from other radio services, Unauthorised usage, Homeland Security, Border protection, Advanced real-time spectrum monitoring. 

 

The 720A exclusively offers users a multi-channel architecture to provide fast and accurate signal measurements for critical safety-related applications. The system consists of a spectrum processor, computer/monitor, TCI’s SCORPIO client-server software and a choice of VHF/UHF direction finding (DF) antennas. The 720A achieves high-accuracy DF performance by using its spectrum processor for simultaneous DSP analysis of wideband receivers connected to an external, multi-element DF antenna array. Each processor channel is composed of a fully synthesised, high dynamic range receiver, high-speed digitiser, and custom digital signal processor. The digital processing provides a wide selection of measurement bandwidths, including 6.25 kHz, 8.33 kHz, 12.5 kHz, 25 kHz, 50 kHz and 100 kHz. This allows the system to be tailored to current and future channel-spacing requirements and to simultaneously measure and analyse more than 40 frequency band channels.
