gps receiver recommendations

hi all,

I need a gps receiver recommendations to simply connect to the marine radio as I currently use a usb receiver connected to my pc chartplotter so I don't need anything more than a bassic receiver just not sure what to look for

Thanks,
yonu

Re: gps receiver recommendations

thanks for the suggestion but I have no interest in features I simply need a recommendation on a GPS receiver no screen or anything as it will simply be connected to the NEMA in port on my marine radio to give it a gps location.

Re: gps receiver recommendations

Buy a GPS antenna with the GPS processor built into the antenna head. The output is NMEA 0183 data. Garmin makes a nice one that I use as backup for my chart plotters.

Garmin GPS17x HVS
http://www.amazon.com/Garmin-010-006...6324635&sr=8-1

I would not get the NMEA 2000 version. There are still too many compatibility problems with that language.

Re: gps receiver recommendations

Anybody know the difference with the strengths of GSP. For example using a marine chartplotter like a Garmin with an inbuilt antenna compared to an android GPS also with an inbuilt antenna..... would one have a better reception and or gaining more fixes with satellites with a more powerful GSP. I have tried to find this answer on the net without much success.

Generally the technology in fixed marine GPS is very out of date compared to the best units available. The speed of fix, number of satellites tracked, WAAS or EGNOS implementation is generally poor. A cheap Chinese GPS unit will do these things much better.
The manufactures claim non marine units are more vulnerable to VHF interference, but there does not seem any practical difference to me.

Where the marine units are better is waterproof ness of the unit and no magnet.

A unit with a display is also better IMHO. It enables the unit to function independently and with much lower power consumption and better reliability than something that needs to be hooked up to a tablet or PC.
If you don't need the display you have no need to mount it where it can be easily seen, but it will still be available if the tablet etc fails. The cost of a marine unit with display like the Furuno GP 32 or a garmin handheld is no more than the simple no display marine units like the raymarine 125. Some of the none marine units can be purchased much cheaper however.

Would you please share with us what type of navigation system you have. That is what kind of chartplotter and or tablet or handhelds do you have.

Re: gps receiver recommendations

3 chartplotters Raymarine Rl 70 and rl80 both with radar overlay.
Simrad nx40 ( for back up depth and AIS)
Simrad and Furuno GP-32 fixed gps units
2 Garmin handhelds
4 pcs with maxsea
2 iPads with gps and navionics maps
B&G instruments that will display readings from either , or even both! depth units or either of the fixed gps units.
2 separate Raymarine autopilots.

I also have a few older gps units as well.

For a crusing boat I think backup fixed gps at least one handheld gps. Two depth Sounders are a value backup if your boat has to be lifted to fit a new transducer like mine does.
Different electronic map systems are helpfully as often one has better detail of anchorages. Navionics for the iPad is a bargin.
Radar overlay on the chartplotter is great because it shows when the maps are wrong.
If you only have one chartplotter mount it so it can be seen at the helm.

Re: gps receiver recommendations

Let's stop right here with responses to Rossad's post please.

Rossad, please start a new thread on your own topic. This keeps the threads much better organized when a person with a different topic has his or her own thread.

Thanks

Woops my apologies David.
Looking at the number of threads you have written you would be right.

Re: gps receiver recommendations

For standalone installations I love Garmin GPS 17.

Otherwise any unit with nmea out does the job.

BTW you can split the signal from whatever you have there as long as it is compatible with the radio. I am not sure how many times the signal can be split but once at least from my humble experience.

You can have 3 "listeners" connected to a NMEA0183 device. This is conservative and up to 5 is usually ok. Turning off the transmission of unwanted NMEA sentences helps, but rather than pushing the number a second GPS gives you redundancy and is a better solution for most boats.
NMEA2000 will cope with more than any normall crusing yacht will need, but you need to take into account the power usage of all devices on the one circuit.

Re: gps receiver recommendations

I considered spliting what I have but my current gps is a USB puck that connects to the pc based chartplotter I wasn't sure if cracking it open and tagging on to the serial wire was a good idea

Thanks,
Reg
