aer2geodetic

PURPOSE ^

aer2geodetic convert azimuth, elevation, range of target from observer to geodetic coordiantes

SYNOPSIS ^

function [lat1, lon1, alt1] = aer2geodetic (az, el, slantRange, lat0, lon0, alt0, spheroid, angleUnit)

DESCRIPTION ^

aer2geodetic  convert azimuth, elevation, range of target from observer to geodetic coordiantes

 Inputs
 ------
 az, el, slantrange: look angles and distance to point under test (degrees, degrees, meters)
 az: azimuth clockwise from local north
 el: elevation angle above local horizon
 lat0, lon0, alt0: ellipsoid geodetic coordinates of observer/reference (degrees, degrees, meters)
 spheroid: referenceEllipsoid parameter struct
 angleUnit: string for angular units. Default 'd': degrees

 Outputs
 -------
 lat1,lon1,alt1: geodetic coordinates of test points (degrees,degrees,meters)

CROSS-REFERENCE INFORMATION ^
