Vector Fluxgate Magnetometer (VMAG) Development for DSX

摘要

UCLA built and delivered a three-axis fluxgate magnetometer for the AFRL-mission. The instrument is designed to measure the medium-Earth orbit geomagnetic field with precision of 0.1 nT and provide the field direction to within 1 degree. The instrument will provide the DC magnetic field for phase space density calculations of energetic particles, the magnetic field vector information for the Loss Cone Imager (LCI) payload, and the ULF wave environment. The project delivered the flight unit in November 2008. Integration and Testing of VMAG and pre-launch testing and on-orbit calibration remain.
