I have a new Ray91 VHF that has an internal GPS receiver and supports an external passive antenna.

I can add a GA150 directly connected, but my plan is to refresh the MFDs also with newer Raymarine gear.

do you guys know if I could either add the GA150 to the VHF and if it will share gps info over N2K with the rest of the network, or could I add an N2K connected GPS antenna (more $$) that the vhf and other devices can then share across the backbone?
 
The new Axioms will share gps sources over n2k.

thanks, the ray91 doesn’t say anything about gps over N2K but since it’s their flagship black box vhf it seems like it should
 
from page 80 in the manual.

GNSS data source Your radio includes a built-in GNSS (GPS) receiver that can be used to obtain position data. Your radio can also use position data from a GNSS (GPS) receiver connected to the same SeaTalkng ® or NMEA 2000 network. If your radio’s internal receiver cannot obtain a position fix or if your radio’s internal receiver is switched off then a network data source for shall be used instead, if available.

thanks Craig, I guess I should RTFM? ;)

I swear I did look for it, just missed it
 
If your staying with Raymarine, either plan on the new Axiom+ models or just buck up for the RS150. The original Axiom are known to have weak GPS reception in certain installed locations (like in the electronics pods next to the Helm).

I added the RS150, made a huge difference in positional accuracy, speed accuracy and cold boot up time from several minutes to almost instant.

at a minimum, getting the GS150 would be helpful.

the difference is the GS150 is a passive antenna, the RS is an active GPS module.

yeah, I’m sort of playing the MFD’s/plotter game by ear. Spent a healthy sum so far on other stuff so I’m keeping an eye out for the a125/127/128 used market and might jump on one if it came at a good price. If I don’t go this season, I’ll probably go axiom.

But to your point - the RS150 solves all these problems. I should probably just buy one and build my N2K network so I’m ready for the MFD. in the meantime I could put the Fusion, Ray91, and RS150 on it and be somewhat future-proof
 
I loved the a128 I had and the LH2 operating system was mature and capable, and the onboard GPS pretty accurate.

For future proofing Axiom is choice, especially for integration of Fusion radios. The Axiom plus upgraded the internal GPS, but I haven't tested. I have my new dash due in a couple days, so I'll be able to test 9" Axiom plus in the dash location. So far it has been a great addition.
 
I can confirm that adding a second gps source to the original axiom improves accuracy and speed. I installed a ar200 and am pleased with the heading data it also provides. Overall I am very satisfied with the new rm equipment.
