  • The double-probe Electric Field Instrument (EFI) is a common instrument used in the space electric field detection. The space electric field can be calculated according to the potential difference and the distance between two probes. In practical work, the wire boom of EFI onboard the spin platform may get position disturbances, which may influence the calculation in distance and numeric values of the electric field. In this paper the double-probe EFI and its working principle are introduced, meanwhile the self-correction method with the processed data of single probe to revise the double probes detection results on a spin platform is illustrated. After eliminating the interference of the platform, the data from the space experiment in sounding rocket is processed with the method introduced in this paper, and the magnitude and direction of measured electric field vectors are corrected. Finally, the correction results are compared with the uncorrected data and the theoretical data to verify the validity of the correction method.
