The instruments that collectively make up the SOAR platform are a gravimeter, magnetometer, ice-penetrating radar, laser-altimeter, and precise positioning GPS, all mounted in a leased Twin Otter aircraft.
Gravimeter A gyro stabilized Bell BGM-3 gravimeter. 70m track line sampling with O(10mgal) precision.
Magnetometer Proton precession towed magnetometer. 100m track line sampling with O(1nT) precision.
Radar Technical University of Denmark. 20m track line sampling. 2000 sweeps in 1/3s.
Laser Altimeter 1500W laser. 8m track line sampling. O(25cm) precision.
Positioning GPS phase data for post processing. O(10-50cm).
