A60 & A65 Upgrade to Support WAAS Accuracy

How can I restore the WAAS capability to an A60 or A65 chartplotter following the FAA's satellite changes?

The Federal Aviation Administration (FAA) recently decommissioned two WAAS GPS satellites (PRN 122 and PRN 134) and activated two replacement satellites (PRN 135 and PRN 138). Raymarine’s A65 and A60 do not recognize satellites 135 or 138 when used in conjunction with the supplied RS12 GPS sensor.

The A65 and A60 continue to receive the standard GPS signals using the supplied RS12 sensor and therefore are safe for navigation. As always, these products are an aid to navigation. It continues to be the user's responsibility to use caution, sound judgment, official government charts, notices to mariners and proper navigational skill when using this or any other electronic navigational product.

The A65 and A60 display can receive WAAS satellite corrections by utilizing an optional RS125 GPS sensor. The following steps detail how to upgrade the A65 and A60 using the optional RS125 antenna (Part Number E32042)

Thanks for the update. I will have to check my own, older, WAAS GPS to see if it knows about these satellites.

Surprising that Raymarine requires customers to purchase a new antenna in order to have full operability of their product. Other manufacturers seem able to deal with the changes via software updates at no expense to the customer. At least this is my impression after reading about the issue on Panbo and THT's electronics forum.

Are you fairly certain that this information is from Raymarine rather than from a seller?

The original attribution was "from another website." Investigate and let us know.

Here's the original attribution from the member on the other forum:

I have the raymarine a65 chartplotter, just got it this year. For those using the chartplotter with gps you may find this email I got today interesting. I did a copy and paste of the basic information and would think it may apply to other chartplotters as well.

Here's the Raymarine web page about it... php?p_faqid=1321

I did not see on the Raymarine web site that you must buy a new antenna. However, that may be the fastest solution for you to be able to receive waas signals.

if you go to PANBO.COM there is a very interesting thread on this issue. Good luck.

Interesting thread over there, Butch. Thanks. For others:

I saw the note on the Raymarine site about the A60 and A65 info to be forthcoming in early September and assumed the email the owner on the other forum got was that forthcoming info.

As I said, apparently from Raymarine.

Apparently you are correct. I went back to Panbo and could find nothing there that offers any help to Moe and other A-65 users other than the admonition to check back in early September.

I'm a little surprised we are not hearing more noise from A-65 users. They certainly kicked up a fuss about the card access doors on the units being flimsy.

I suspect the lack of fuss is because it's the end of much of North America's boating season, and unless you have a National Geodetic Survey control point to compare your GPS position to, how many of us notice the difference between +/- 30 feet, and +/- 10 feet on the chart at the scale we usually view it at? +/- 30 feet still plots me inside the banks of the 150ft wide canal behind my house.

I guess it's all in where (sorry) and how you boat. Most of my boating is in the Mobile Bay Delta which is poorly charted and with few nav aids.

I depend upon the tracks feature on my GPS to return to places where fishing is sometimes productive. Getting to some of these spots can require some slow going and careful observation.

If I can depend upon my GPS to be accurate to about 15 feet I can consistently return to my spots without difficulty or delay. At 30 feet of accuracy I feel it necessary to go much more slowly and carefully.

I'm able to gage the accuracy of my fix by checking my position at the ramp vs my previous plot trails. If I'm siting on my previous trail at the ramp I believe my fix is highly accurate.

Thankfully, we boat year round here although I don't get out too often in August.

WAAS accuracy is important to me. In one case, I'm trying to
anchor in an 8' x 15' patch of sand. In a number of other
cases, I'm trying to anchor just downwind of a small target,
but miss it so I don't damage it. Fortunately, my Garmin
162 just kept on working through this change.

It's not about accuracy, it's about repeatability.
