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.
