About
NewSpace Systems’ magnetometers employ AMR sensor technology with integrated offset compensation circuitry delivering X, Y, Z magnetic field measurements plus temperature for drift compensation. Low-noise processing and ADC circuitry improve linearity and reduce temperature sensitivity. The device operates on a regulated 5V DC supply with digital serial interface output. Radiation-tolerant COTS components are used throughout and each unit ships with a calibration matrix. First flown on the CINEMA mission in July 2014, the design has achieved TRL 9 with over 400 units in orbit across 5 constellation programs.
