I'm using a block in Simulink to get XYZ coordinates of an aircraft in ECEF frame from Lat, Long, Alt of a GPS. How can I transform XYZ from ECEF frame to XYZ in navigation frame (Frame of aircraft motion) ? Select the China site (in Chinese or English) for best site performance....
I simply try to convert a point from local Cartesian ENU centered on a point with lat,lon coordinates to geocentric ECEF coordinates. With proj from command line all works well. I use strings from proj to create QGIS CRS, and it seems all works well, i receive true in return code. But...
(I can't check because I don't have the mapping toolbox. I can confirm your measurement - my own code estimates the separation at 83.65 m.)The default reference ellipsoid is a unit sphere. Instead, try using a wgs84 earth model and you will get a result much closer to what you we...
