[GPS-20A] [KGP-920] [KGP-913D]

GPS-20A
In-Antenna Type GPS Receiver Module

True Parallel 18-channel GPS receiver.

• The TRUE 18-channel parallel receiver provides precise and quick positioning at any time.
• WAAS and EGNOS ready--The satellite based positioning correction system will be fully operated within a few years time. The systems called WAAS (USA) and EGNOS (EU) are in trial phase which services are broadcast now.  The GPS-20A is ready for receiving the seamless correction signals provided from these systems.
• NMEA 0183 interface with provision for external RTCM SC-104 differential corrections.
• The NMEA output supplied as standard, providing hihgly accurate positioning and navigation data to externally connected equipment such as a radar, plotter, sounder, DSC VHF, etc.
