Author Topic:   VHF Marine Band Radio with Internal GPS Receiver

Is there a Class-D DSC VHF Marine Band radio with internal GPS? The reason I ask is apparently one of the connections between my Standard Horizon chart plotter and my Standard Horizon DSC radio is intermittent causing loss of navigation information to the radio.

I am sure it is something I can repair for a reliable operation.

It seems that natural progression of design would eventually include a GPS receiver in a VHF radio. I can't name a brand or model at the moment, but I am sure I have seen handheld VHF radios with DSC capability and internal GPS receivers.

I don't think that a good location for a GPS receiver would be inside a VHF Marine Band radio. You'd have to mount the VHF Marine Band radio in a location so the internal GPS receiver could see a full clear view of the sky.

Most GPS receivers that are made now are contained entirely on one large chip fabrication, including the antenna and a serial data interface through which they transmit their position data to other devices. There are a few GPS chip fabricators, and most receivers use one of these commodity chips.

If the VHF Marine Band radio had an external GPS receiver, it would not have any advantage over just having a stand-alone external GPS receiver with a network interface. It would need to be connected to the radio. Now there's no difference between connecting the radio to a chart plotter with a GPS receiver.

In a sophisticated installation of a global positioning system receiver (or GPSr), a VHF Marine Band radio with digital selective calling (DSC), and a chart plotter, it would still be necessary to make a wired connection between the radio and the chart plotter in order that the radio could send data to the chart plotter. The radio needs to send data to the chart plotter in order to display the location of target vessels whose position has been received via DSC communication. In this instance it will still be necessary to make a wired connection between the chart plotter and the radio. Having the GPSr integral to the radio does not help avoid the necessity of that wired connection.

Standard Horizon makes (or made) combination VHF-Chartplotter fixed-mount units.

I suspect they use(d) an active antenna, however.

I would post a link but their web site is down.

Building a radio into a chart plotter makes more sense than building a GPS receiver into a radio. When I use the term "GPS receiver" I mean just that, and not a multi-function display, chart plotter, and GPS receiver combination unit.

A modern GPS receiver costs about $35 at retail in single unit quantity. At wholesale and in production quantity, I anticipate the cost of a GPS receiver would be under $20.
