PROTON MAGNETOMETER TEST ON BOARD A SURVEY AIRCRAFT,
Abstract
During June and July 1965, a proton magnetometer was tested on board NAVOCEANO's Project MAGNET NC-54R survey aircraft to determine the feasibility of operating an absolute reading instrument inside the fuselage, under survey conditions. A toroidal sensing element and standard compensation methods provided positive results during three air swings. Interference with the vector-measuring flux-gate elements on board the aircraft was no greater than one gamma during the proton polarizing intervals. The proton magnetometer values were compared with values obtained with a meta-stable helium magnetometer utilizing a towed sensor. The report describes the procedures used for testing and compensating the proton instrument and concludes that it is definitely feasible to obtain accurate total magnetic intensity values by operating a compensated proton magnetometer inside the aircraft.
