The Spin-plane Double Probe (SDP) and the Axial Double Probe (ADP) instruments are part of the
FIELDS instrument suite of the Magnetospheric Multiscale mission (MMS). The combination of SDP
and ADP is referred to as the Electric field Double Probe (EDP) instrument. EDP measures the 3-D
electric field with an accuracy of 0.5 mV/m over the frequency range from DC to 100 kHz. SDP
consists of 4 biased spherical probes extended on 60 m long wire booms 90° apart in the spin plane,
giving a 120 m baseline for each of the two spin-plane electric field components. ADP consists of 2
biased cylindrical probes extended on ~12 m long stiff booms along the spacecraft axis, giving a 29.2
m baseline for the axial electric field component.
