GPS system used by BO consists of two parts:
- GPS/GNSS antenna
- GPS controller (that does the necessary calculations)
Isn't the GPS controller integrated in the BLUE system board (with my BLUE mini board its integrated). This means you normally cannot swap it out for another.
For the antenna though, you can use a different one if you like. They are all connected using the SMA connector on the board.
Tom,
... the newer blues ( and the Blue Mini) should use highest baud, and our older Blues and Reds 115200. I personally use GPS+Glonass with SBAS enabled on my Blues, and Reds don't give me a choice of constellation, but , I do enable SBAS... since I normally have a GPS SBAS sat (133,134,135) in view.
It's not as critical now, since all signal time stamps are assigned by the receiving server, but it's important to keep that 1pps in sync.
I've stayed in the 'lower end' antennas, after experimenting with a few supposedly better one... didn't notice much difference... my issue is simply having them in location to view the largest constellation areas... location seems much more important than 'variety' or brand of antenna, at least for me. For the last month or so, my reception has been degraded compared to ongoing history. My latest Blue (3020) has a LOT more GPS loss than the other three, and the antennas for each are in the same 18" area!
I've a GPS status page cobbed together here: https://sferics.us/GPSinfDat.html which I refer to once in awhile...

Hi Cutty,
Interesting ...
I had the same problem with my System Blue 'Classic'; GPS loss and a lot of blue vertical lines. This started a year ago.
I did some tests and for me it turned out that selecting only receiving 'GPS' en 'Galileo' fixed the problem.
For some reason also choosing 'Glonass' created the errors in my situation.
Maybe it is to much satellite information for my 'old' onboard Mediatek GPS module to process?
My System Blue 'Basic' is doing fine for all three; GPS, Galileo and Glonass, always 100% and no vertical blue lines ... I can even add BeiDou and still get 100% and no vertical blue lines.
I'm using the 'U-Blox ANN-MB1-00 MULTI-BAND antenna' for both my System Blue.

Roel
