Fig. 1From: A 2015 International Geomagnetic Reference Field (IGRF) candidate model based on Swarm’s experimental absolute magnetometer vector mode dataMagnetometer payload setup. All instruments of the magnetometer payload are mounted on a deployable boom, with the vector field magnetometer (VFM) and the star tracker (STR) assembly sharing a common rigid optical bench and the absolute scalar magnetometer (ASM) mounted 2 m away, at the tip of the boom. The main body of the satellite (not shown) is on the right (towards the direction of flight, as indicated by the arrow)Back to article page
