INTRODUCTION

When two GPS’s are fitted, this device selects the “best” for transmission to the electronic chart system, GMDSS or radar.The 909 (B) recognises the quality modes of the GPS signals. If the status of both GPS signals is equal, channel 1 is selected as the priority channel.

Two output options are available, selectable by jumper: -

1. The 909 reads in the data from each GPS, stores it separately, and generates its own output message. The interface outputs position, cog, sog, date and time. If this does not meet your needs we can program the 909 to suit your exact requirements.
2. The 909 passes through all the data from the selected GPS.

SPECIFICATION
