measure, compensate and display. Variation/Declination and inclination!

A fixed value for one location might be unsufficient for long flights and or usage of the variometer in a different geografic location.

Can the UBLOX GNSS provide this information?

MaxBaex commented 3 years ago

The M9N U-Blox seems to not provide the Magnetic Declination in the UBX-NAV PVT message. (Shows n/a) Do we need to provide a database: https://www.ngdc.noaa.gov/geomag/WMM/ https://www.ngdc.noaa.gov/geomag/calculators/magcalc.shtml#declination

There shall be a description how the variation must be configured for the the single GNSS variant.

Magnetic calibration reworked. Declination and inclinatin measured automatically.
