Rugged, high-performance Assured-PNT and central radial clock 3U VPX module with integrated Alternative RF Navigation receiver (software for US version only) and atomic clock-backed NTP/PTP timing. The module supplies real-time external PNT sources over Ethernet and supports standard M-Code and SAASM GPS modules. Aligned to the CMOSS, VICTORY, and SOSA Technical Standards, this all-in-one approach reduces complexity to provide high assurance, accurate navigation, and timing in GPS-denied environments.
