NAV/COM REVIEW Consilium Selesmar Updates Radar Series Consilium Selesmar has presented its new NAVBAT ARPA radar, designed with the latest technology. Its range combines either an up- mast X- Band transceiv- er or a down-mast solid state transceiver with a 20-in. color display providing full ARPA facilities, which is housed in an ergonomic desk mounting cabinet. For high speed vessels, there is also a high speed X band antenna option. Other features of the NAV- BAT ARPA radars include advanced fully digitized video pro- cessing, and flexible interface for connection to position and naviga- tion systems via NMEA 0183 stan- dards.

The receiver is designed to be internally installed into Micrologic's Millennium series 12-channel fixed-mount GPS receivers and can operate in either manual or auto- matic settings. The H-field anten- na attached to the receiver are unaffected by alternator noise and lighting and can be installed inside most boats. The ML-9200 features a maximum lock on time of 10 sec- onds and is capable of sending DGPS data to other GPS receivers.

The 12-channel, onboard system takes the best combination of visi- ble satellites to calculate the ves- sel's position to within one meter. The receiver and its PC is con- trolled by a single keyboard and .2 i i provides flexible data logging and processing capability. Using its internal microprocessor and resi- dent software, the unit logs posi- tion and sensor detail to its hard drive while providing the helms- man with full track guidance facil- ities, including line printer and plotter. Upgrades in software are w readily installed via the disc drive. The system receives its differen- tial correction data from a fixed reference station and the correc- tions are calculated by a Del Norte 2012 reference receiver and trans- mitted via a UHF data link.
