Mission Planner GEOID

Does anyone know what GEOID Mission Planner uses? Is there a way to change it?

Thank you,


MP displays what is sent to it.
which in most cases will be wgs84. as that’s what the gps is setup in.

ucenter uses egm96 on a average grid. The elevations are ellipsoid related and averaged on a grid of unknown size per the geiod so elevations if using a ublox are not related to a level surface just the ellipsoid.
WGS84 is a horizontal reference and does not relate to vertical data.
What is needed is a correct geiod height added to the ellipsoid returned by ublox GPS so elevations are correct. For this users would need to select a downloadable geoid file. https://www.ngs.noaa.gov/GEOID/index.shtml
The geiod files would be applied to the WGS84 horizontal data & calculate the correct geoid height (actual MSL elevatrion).

Could this be done? I would be willing to invest in the project.
