sarkit.cphd.hae_llh_to_iac

hae_llh_to_iac(pt_llh, iarp_llh, uiax_ll, uiay_ll)

Convert from geodetic LLH coordinates to IAC coordinates for Surface Type = HAE

Parameters:

pt_llh(…, 3) array_like

Array of positions in geodetic LLH coordinates with [latitude (deg), longitude (deg), and ellipsoidal height (m)] in the last dimension.

iarp_llh(3,) array_like

IARP position in geodetic LLH coordinates.

uiax_ll, uiay_ll(2,) array_like

Vectors containing increments in latitude and longitude in radians per meter for 1.0 meter displacements at the IARP in the +IAX and +IAY directions, respectively.

Returns:

pt_iac(…, 3) ndarray

Array of positions in IAC coordinates with IAX, IAY, IAZ components in meters in the last dimension.
