How to use this calculator
- Enter a reference latitude/longitude/height.
- Enter the azimuth, elevation and range to the target.
- Press Convert to get the target's ECEF position.
How it works
Converts a line-of-sight Azimuth/Elevation/Range observation into local East-North-Up, then into absolute ECEF coordinates about the reference point.
Worked example
Az 45°, El 10°, 1000 m. Returns the East/North/Up and the absolute ECEF X/Y/Z of the target.
