I'm looking for an external, rail-mountable, active GPS antenna with a NMEA 0183 output. Don't need a display as it will interface with my PC and other displays. 

Any recommendations? ( I thought this topic had been discussed a while ago but I've searched the forums without success.)

I have a GPS 19X HVS from Garmin connected to my PC (with Adrena running as routing software) and I am very happy with it. Fast, accurate an reliable.

I purchased an external g.p.s.antenna from these guys in singapore, thru ebay, delivered to my door in Lake Macquarie within 5 days.

Good to hear, this is the one I have been thinking of.

What's the mount like? I guess I'll need a rail-mount.

It comes with a deck-mount and a pole mount. The other gps on board is a raymarine deck mounted and it is loosing the signal on a too regular basis (don't know if the problem is the deck mount or the gps itself but what is sure is that if somebody is seated above the antenna, the signal is lost). My Garmin module is on a "T-Pole" fixed on the transom, that keeps the rail clean and the antenna clear, useful if you have teak seats in the back pushpits ;-)

If you have additional antennas (iridium, vhf, wifi amplifier, etc) the T-Pole is a nice solution, if not rail-mount is the way to go in my opinion. You will just need to buy something like that: http://www.scanstrut...&type=Sailboats

Take a look at this option: 

Airmar GH2183 GPS Heading Sensor 10Hz
Product ID: AM1101-000         MFG ID: GH2183-10
Airmar GH2183 10Hz combines GPS positioning and highly accurate heading information in one compact antenna. The GH2183 eliminates the need to install a GPS antenna above deck and a heading sensor below deck. Only one installation above the deck is required, saving installation time and money.

I have one of these as back up to my primary antenna.  It is a great unit, I highly recommend it. 

 

The bottom of the antenna can thread onto any 1" NPT rail mount, and then you need their cable (specify NMEA 2000 or NMEA 0183).  They come in a few different lengths, so order to fit your installation.  Then that will plug into a small converter box that takes the GPS output and pushes it out to a USB plug for your PC.  That will run you $125 for the WS-UBS.  Alternatively, you might want to push out a signal to your VHF so you can have DCS working, in which case you are going to want the WS-UBSN which has a UBS output for your PC and then separate 0183 output.  That box is more, around $380.  Both of those are in addition to the antenna.

I can 2nd the recommendation. I have one interfaced to my VHF. Never a problem with it. Mine is mounted under the deck so it's invisible and no clutter.

Pretty bloody expensive, >$700! Even the basic (GPS only) is >$200.

 

Still leaning towards the Garmin (~$150), as I've since discovered that my primary problem isn't my old steam-driven GPS, but the driver for the serial/USB interface to my PC. I just upgraded from Vista (shit) to Windows 7 (OK so far). My old serial/USB cable doesn't have a 7 driver so I had to get a new cable but its driver causes NMEA communication to slow to a crawl (apparently a common problem). There's another driver which is supposed to work OK; I'll try it out tomorrow.....

I'll use the Garmin as a primary and my old one as back-up. At least the PC doesn't think the GPS is a mouse anymore!

 

Ain't PC/instrument communications fun!!

Add an NMEA to WLAN box and ditch the cables  - no more serial/USB issues

what kind of serial to USB did you get?

 

this is one thing that it's best not to get cheap on - I typically use a Digi Edgeport 1 - generally around $70, but sometimes less on ebay.

 

if you want to go wireless with your old GPS, it might be better to use serial to bluetooth rather than  wifi.

My plan is to go wifi soon, probably the Shipmodul Miniplex-2wi, but I'd like to get the current setup working in the interim.

Also don't like to admit defeat!

My serial/USB is a generic one, probably a part of the problem. I'll look at a better one.

This sounds good, GPS and Glonass in one antenna, high baud rate, 10Hz updating, and way not as ridiculous expensive as the Airmar GH2183:

10hz ( at low cost, under $200)is a big step forward for a yacht but your kit will need to process the glonass and the navstar strings to make use of them or it will just ignore them I assume?

Reading the manual it will calculate at 10hz but only output at 6hz if you use only one sat system, thats still way better then a 1 hz system

Most manufacturers never want to explain that

I question how much you even need and external unit anymore as my current Standard Horizon HX851 DSC  unit will pickup a single in the basement of my house

 

My oldest Magellan Pioneer GPS was always hard pressed to work in anything less than perfect a sky-view 

 

gotta love progress :)

Fixed the problem by downloading the latest (Vista) driver for the USB cable, works with Windows 7!

 

Under deck antenna sounds very interesting; the fewer thins on the rail and the fewer deck penetrations the better.

Any problems encountered with them so far?

I use the Standard Horizon gps puck to send the info to the SH Matrix. I mounted mine on the cabin top, but a rail mount would not be difficult.

Won't work with Carbon hulls, and won't work if there is a lot of water on deck.  But otherwise... good to go.

Water on the deck is standard on our boat! Generally that's also when its important to know where one is....

Sounds like either the Garmin GPS 19X HVS  or the DY GPS 150 Dualnav.

yes, but it does L1 and L2 signal processing...and I can't see if Garmin GPS 19X HVS  or the DY GPS 150 Dualnav do. I have 2 of the garmin 17 that do L1 and L2 processing at 5Hz updates but was looking into upgrading to 10Hz or even 20Hz. The DY GPS 150 Dualnav is only a 6Hz updates (if I am reading the manual correctly) so it does not buy me much

Couple of options

Tacktick use these and just rebadge them  - expensive but good -  http://www.sanav.com...s_receivers.htm

 

OR
You could grab the GME AIS receiver unit and use the NMEA GPS data - as well as gain the AIS benefits.

 

and it's NMEA 0183 and 2000 data outputs will future proof your purchase.

 

GME AIS GPS NMEA data with AIS RECEIVE  $219
 

http://www.gme.net.a...stems-1/AISR120

 

GME AIS GPS NMEA with AIS transmit and receive $549

I cant see on the spec sheet where it says it can process L2 data nor any garmin equipment. That would up the accuracy a lot.

Can you point me to where it says that?

Some of the other systems on the Hemisphere website offer L1/L2 capability and also 10 & 20 hz channels. We actually use a pair of Trimble SPS351's for our survey work.

I have a digital yacht AIS, works like a clock... more than I can say for the three Standard Horizon handhelds I have that seem to have some sort of failure every 2 years or a part break a day out of the box.

Installed the Garmin 19, works just fine so far. Had to slow it down to 1Hz for the rest of my systems, but hopefully can speed it up as I upgrade them.

Interesting about the Standard Horizons, Our GX 2100 VHF/AIS has worked great for the past couple of years, as did its predecessor for the last 15 years!

Pretty bloody expensive, >$700! Even the basic (GPS only) is >$200.

 

That unit is also a VERY accurate 3-Axis Compass with 3-Axis Accelerometer & 3-Axis Rate Gyros.  That heading sensor is the same one NKE uses in their top of the line installs (although they update the firmware to better integrate with their systems).

 

Look at this as a top notch compass AND GPS solution.  This is our PRIMARY sensor for both GPS and heading (other than our old Ritchie globemaster).

http://www.digitalya...oducts_id=11706

This is what I use with very good results so far. Especially like that it appears that there is no internal filtering trying to smooth out all the data - I suspect that Garmin uses some form of filter and DR's between 'fixes' as have had overshoot etc from their antennas. You can see the 150 bouncing around when zoomed right in - which would be expected with accuracy and resolution from non-survey grade GPS. Rather that than the boat sitting nicely in one spot - not real data.
