The last couple of times out on the boat I seem to have a problem getting a GPS Fix with my Raychart 320 Chartplotter...
It takes a long time to get a Fix, and when it does it looses it pretty quick...
Has anyone else experienced this problem?...
Is there something wrong with the Sattelites, or do I have a GPS/Antenna problem?...
 
No problems with the Constellation Wayne. Check your antenna connections. I am not familiar with the RayMarine 320 does it have a coaxial cable to the GPS or is it regular muti-conductor wire (NEMA0183) based?

If you have a volt meter remove the antenna and see if you have 5 volts DC from the center pin of the antenna connector on the GPS and the shield or any ground on the GPS. If you do or the voltage is higher try changing the antenna connector 1st or get another antenna and just try hooking it up without a full install and see what happens. Bill
 
No there are no problems with the constellation but some GPS makes/models could be experiencing some firmware issues due to a week rollover issue which eventuate from the satellites.

Since when has this been occuring?
 
Last year it was good...I just started using the Plotter last week for the first time this year, so 1 week of problems for me...
 
When or if it has a satellite page showing the birds do you see them? If you do then it could very well need a firware upgrade. A new bird was added the end of last year Wayne it has effected many of the older GPS units.

Do you want to depend on that???? I boat in the western half of Lake Erie. You half to know where you are, GPS goes out and now what, people do it and pay the price.

Jim I have 3 so even 2 can go out and I still have GPS on the chartplotter. I also have 2 depth finders one on my network and the other stand alone. Then the back up a compass and current maps that I know how to navigate with. The new GPS Chartplotters have come a long way in the last 4 years.

I also carry paper charts with me...

Bill:
Birds???...You mean the bars??...How do I get one of these firware upgrades...does it have to be sent to the factory for that?...

There have been multiple reports of GPS problems beginning on or about June 11-14, 2009.

The recommendation is to contact your receiver's manufacturer with GPS issues coinciding around this time frame.
 
Will do Kerry...

Just out of curiosity...are you the Kerry from Digiboat?...
