Sensis successfully completed the Critical Design Review (CDR) for the Canadian Department of National Defence (DND) Terminal Radar and Control System (TRACS) Area Surveillance Radar (ASR-3) modernization program. The CDR entailed a detailed review of the system design and components that Sensis will employ to replace original hardware. Modernizing components of the TRACS/ASR-3 radar will extend the overall service life and reduce operating costs by improving reliability, ensuring availability and simplifying maintenance procedures. Sensis will replace the majority of the TRACS/ASR-3’s original electronics with proven commercial-off-the-shelf (COTS) hardware, including a modern Signal Processing system and a highly reliable Solid State Transmitter. Sensis’ open architecture approach allows for easy integration of future technologies and capabilities.
