%X In 2016, Geotech completed a test of a helicopter-borne GT-2A gravimeter combined with ZTEMTM (Z-Axis Tipper Electromagnetics) and aeromagnetic towed bird system over the Vredefort Dome impact structure in South Africa. The survey consisted of nine (9) approx. 70 km long NW-SE oriented flight lines, totalling 640 km, acquired at a nominal spacing of 500 m over an area of approximately 650 km2. The successful test demonstrates the feasibility of integrating density measurements using airborne gravimetry on a helicopter platform while combining the superior depth of investigation of ZTEMTM and aeromagnetics for regional geophysical survey applications.
