FURUNO GP 1250The GP1250 is comprised of a slim profile antenna and compact receiver. The high-sensitivity, dual-channel receiver tracks up to 5 satellites simultaneously. In addition, an 8-state Kalman filter is utilized for optimum accuracy in determination of vessel position, course and speed.Navigation information is displayed in yellow-green on a high-resolution 7-inch flat-face screen. A hood with a magnifying lens is supplied as standard.The ship's track is calculated on 2 separate pages; a touch of a single key instantly flips between the 2 pages without having to wait for the computer to replot a picture. Scale factors may be customized by the operator between 1/2,000 and 1/5,000,000, or 0.14 and 360 nm in horizontal range.On-screen alphanumeric nav data include ship's position in Lat/Lon, speed/course, cross-track error, cursor position, range/bearing to cursor, range/bearing (or ETA/TTG) to a waypoint, and system parameters. All parameters, as well as past courselines, are retained in the built-in memory and backed up by a lithium battery.Standard FeaturesC/A Code, Dual Channel ReceiverHigh-Speed Multiplex Tracking of up to 5 satellitesUp to 15m RMS position accuracy without SAUp to 0.1 Knot RMS Velocity Accuracy without SA250 Knot Tracking Velocity8-State Kalman FilterHybrid Navigation with Loran, Transit, etc.Accomodation of RS232C peripheralsAdjustable map scale of 0.14 to 360 n.m.7" flat-face yellow-green CRT100 Waypoint memory17 Lines of navigation dataPlot Interval may be set by Time or Distance3-Partition memory of Courseline and Event PointsInternal RAM of up to 1,800 Track Points an 1,524 Event PointsData in/out NMEA/CIF formatsVoyage planning by Waypoint or up to 10 RoutesPower Requirements11-40 VDC, 22 Watts12 Watts in Economy ModePowered by eCRATER .
