I am using the QWIIC NEO_M8U UDR to acquire positional data for vehicle modeling purposes. One of the most important data input requirements is accurate road grade which is greatly influence vehicle power train load due the mean old gravity. Other UDR/ADR (Skytraq’s) includes a baro so I want to add the same functionality to the M8U UDR. Any suggestions would be helpful.
Thank You

Hi Bruce, thanks for posting!
I don’t see anywhere in the NEO-M8U documentation that this GPS supports an external barometer. You could connect a barometer and the GPS to a micro controller and then with a bit of code use barometric pressure to determine altitude and somehow slip that into your data stream though.
You would need to account for changes in weather though since that can affect barometric altitude by hundreds of feet from one day to the next.
