1948 Bull. Géodésique No. 10. 342 A network of triangles may be computed and adjusted from observed lengths of sides. The development of error in trilateration is different from that in triangulation..as the side error is not accumulative.
1952 G. Bomford Geodesy i. 34 It might be possible to use radar trilateration between ground points instead of ordinary geodetic triangulation.
1960 Times 4 Mar. 3/2 Experienced in first order triangulation, trilateration and astro-fixes.
1974 Physics Bull. Apr. 136/3 A geodetic network was established to an accuracy of 2 mm over the surface of the Laboratory II site using triangulation and trilateration.
