Wide area multilateration algorithms suffer from stability issues related to the fact that the reference points are nearly coplanar. This paper presents a method to add elevation angle measurements to a multilateration problem and thereby reduce the error perpendicular to the plane where the measurements are taken. The resulting measurement error is significantly reduced for co- planar and nearly coplanar reference points.
