Dual GPS setups

GPS / RTK / GNSS

I highly doubt it, since there is some calculations to do on heading/roll and various other options, which is what the ESP32 does.

I use this ESP32 https://www.digikey.com/en/products/detail/espressif-systems/ESP32-DEVKITC-32D/9356990?s=N4IgTCBcDaIIwE4BsBWAtHADNtA5AIiALoC%2BQA

However many other ESP32 works as well.

The original connection diagram still lives at AOG_GPS_ESP32/Dual GPS setup.pdf at master · mtz8302/AOG_GPS_ESP32 · GitHub

I am developing a different setup using Sparkfun F9P. The code is here GitHub - AOG-addendum/Dual-GPS: Dual Gps forked from mtz8302 for the PCB module in the AOG-addendum repo. The PCB is PCB-modules/Dual GPS at master · AOG-addendum/PCB-modules · GitHub use the REV C.fzz file.

I would highly recommend using one of Benjamin’s dual GPS boards. They are already set up for ethernet and there is no wiring except for power.

This! Along with Tony’s dual code, which allows AOG to do all the roll calcs as it would normally…and antenna offset also done in AOG as per a normal single setup… nice and simple and nice and reliable!

Help, why can’t I connect and how to use it

Why is my AOG reading(top right corner) that I am using DGPS when I have single antenna? Is that a problem?

DGPS means Differential GPS not Dual, it’s a term of Signal Quality, if you are driving without RTK this is the best Signal quality you can get without correction Data, otherwise you need to reconfigure your correction settings so that it shows RTK Fix instead of DGPS

Thanks… it was saying Single before, great

I’m trying to get Matthias’s code to work, but I can’t get it to work.

I soldered the wires on the f9p modules as shown on the examples and explained in the *.info

tempImagesS6xK4
tempImagesS6xK42419×1814 1.31 MB

And made the stack with the same ESP32 as in the example images.

When uploading the *.ino to the ESP32 I changed

  • DataTransVia = 0;
  • NtripSendWhichGGAScentence = 0;

When connecting to AGO the gps-icon lights up green for couple of seconds then red, then green, then red…

Also tried switching the pin numbers in the code byte RX2 and byte TX2
(because somewhere was written that the print on the ArdusimpleReceivers is wrong… but what with the images supplied in the repository??)

With debugmodeUBX = true; I don’t receive coordinates in the serial monitor.

Connecting to the hotspot works fine, but that does not help me (also; the heading numbers remain red)
Tried some other stuff as well, but can’t remember everything…

Can anyone point me in the right direction?

Why not using the actual V4.5 Board with the teensy firmware?
