C-Nav1PPSI Converter/Combiner
The C-Nav1PPSI converter/combiner is a multi-function interface for GNSS receiver 1PPS signals. It has two opt-isolated 1PPS inputs, which are connected directly to the receiver's 1PPS outputs.
For high-integrity systems with dual GNSS receivers, the interface will "OR" the two TTL sources for output to peripherals that require a continuous 1PPS for time stamping. This output is maintained should either GNSS input fail.
SAAB R6
The SAAB R6 is a type approved IMO-compliant navigation system featuring sensor and 7" CDU(Control and Display Unit).
The R6 NAV includes a Bridge Alarm Management system, dual LAN interface, 1PPS output, 8 output and 5 input ports, IALA and RTCMv2 input, Multi constellation GLONASS, GALILEO and BeiDou GNSS.
The R6 comes in 2 variants the 'R6 NAV DGNSS' or 'R6 NAV PRO' model, with the PRO version giving access to Atlas® differential L-Band centimeter level corrections.
Antennas
C-Nav289
The C-Nav289 is a GNSS antenna that tracks all GNSS constellations, C-Nav corrections, and SBAS satellites. It has special out of band rejection filters for INMARSAT and IRIDIUM®. It is housed in an all-polymer enclosure for marine application. The antenna is listed in the NOAA GNSS Antenna Calibration tables as C-Nav289.
C-Nav Combiner
The C-Nav Combiner enables the use of separate GNSS and L-band antennas. It is used in high-latitude operations where the low look angle of the separate L-band antenna enables reception of correction signals that is not possible with a standard integrated GNSS/L-band unit.
This combiner can be mounted on the mast or locally with the GNSS receiver.
