Convert WGS 84 (CTS, ECEF) Coordinates to ECI (CIS, Epoch J2000.0) Coordinates. This function has been vectorized for speed. The associated error in converting between coordinate frames is on the order of 1.2*10^-11 km when compared to STK ephemeris output.To run this function type the following...

Geo::ECEF is a Perl module that converts between ECEF (earth centered earth fixed) coordinates and latitude, longitude and height above ellipsoid. SYNOPSIS use Geo::ECEF; my $obj=Geo::ECEF->new(); #WGS84 is the default my ($x, $y, $z)=$obj->ecef(39.197807, -77.108574, 55); #Lat (deg), Lon...

Convert ECI (CIS, Epoch J2000.0) Coordinates to WGS 84 (CTS, ECEF) Coordinates. This function has been vectorized for speed.Example Function Call:>> [r_ECEF v_ECEF] = ECItoECEF(JD,r_ECI,v_ECI);Where:JD is the Julian Date vector [1 x N] (units are in days)r_ECI is the position vector [3 x N] (any...

ECEF2LLA - convert earth-centered earth-fixed (ECEF) cartesian coordinates to latitude, longitude, and altitude.USAGE:[lat,lon,alt] = ecef2lla(x,y,z)lat = geodetic latitude (radians)lon = longitude (radians)alt = height above WGS84 ellipsoid (m)x = ECEF X-coordinate (m)y = ECEF Y-coordinate (m)z...


Platforms: Matlab

The function assumes the WGS84 model.Latitude is customary geodetic (not geocentric).Inputs may be scalars, vectors, or matrices of the same size and shape. Outputs will have that same size and shape.Usage[lat,lon,alt] = ecef2lla(x,y,z)lat = geodetic latitude (radians)lon = longitude (radians)alt...


Platforms: Windows, Mac, *nix, Matlab, Solaris

A collection of geodetic functions that solve a variety of problems in geodesy. Supports a wide range of common and user-defined reference ellipsoids. Most functions are vectorized. Functions include:Angle Conversions deg2rad - Degrees to radians dms2deg - Degrees,minutes,seconds to degrees...
