About the GPS status display

•This display is available with a FURUNO BB GPS receiver or other GPS receiver connected via LAN and outputting NMEA 0183 data.

•The receive signal level table shows the receive signal strength of 12 GPS satellites and one WAAS satellite. (GSA, GSV sentence necessary for GP-330B, WS-200 and other GPS receiver.)

•The WAAS satellite whose GSA data is first received, in case of the GP-330B, WS-200 and other GPS receiver, is used for the display. When there is no GSA sentence and the GSV sentence contains data from several WAAS satellites, the WAAS satellite having the highest elevation and best SNR is used for the display.

•The satellite position diagram shows the arrangement of GPS, GLONASS and WAAS satellites in the sky. A total of 36 satellites can be displayed. The type of satellite and number of satellites that can be displayed are as follows:

GPS, 1-36; GLONASS, 65-96, WAAS, 1

•ALT indication is only available with GP-320B.
