Since 1979 the Institute for Engineering Design and the Danish Space Research Institute have flow magnetic field measuring instruments on board 7 NASA and European ionosphere scientific sounding rockets reaching altitudes up to 1000 km. Several future rocket flights are planned, and an ultralight magnetometer sensor for satellite missions is under construction jointly with the Department of Electrophysics at the Technical University of Denmark. Ten compact spherical coil sensors were calibrated determining the magnetic axes' deviations from being exactly orthogonal. The deviations ranged from 0.4 x 10(exp -4) to 66.3 x 10(exp -4) rad averaging to 17.0 x 10(exp -4) rad. The six best sensors had an average deviation of 7.85 x 10(exp -4) rad from orthogonality of the angles between the individual magnetic axes. All the sensors' alignments compare favorably with the Magsat sensor alignment, and the best sensors had almost an order of magnitude smaller alignment errors.
