The general idea for instruments arcitecture for the PMO mission is to have the identical set of instruments located on the board of seven identical spacecraft, via the two independent interface connections to the spacecraft managed by two electronic boxes: BOX-W and BOX-P
The Polish contribution to the PMO mission includes scientific, instruments and management aspects for both BOX-P and BOX-W units. CBK PAS leads the activity in the frame of BOX-P at management and system engineering.
The BOX-P instrument serves as a common electronics box, housing the front-end electronics for the flux gate magnetometer MAG and its sensors, a common power supply unit PSU, and a common Data Processing Unit DPU. The BOX-P electronics box also implements the common power and
data interface for the particle diagnostics instruments: iEPC, EPE and IMCA. BOX-P implements the single communication interface for the entire sisters spacecraft payload. All sets of instruments are dedicated to the in situ, multi-scale, multi-point study, through simultaneous measurements, of plasma energisation and energy transport in the Earth's Magnetospheric System.
CBK PAS leads the activity for EFI, the Electric Field Antenna and the manufacturing EFI-ADA sensor. The Electric Field Dipole Antenna (EFI-ADA) is connected to the BOX-W suit instrument, which measures the AC electric field from DC to 100 kHz. The EFI-ADA sensor consists of a single dipole antenna. The sensor will be mounted near the end of the rigid magnetometer boom on which SCM is mounted and will feature an orthogonal-to-the-boom dipole antenna, approximately 4.0 meters from tip to tip.
CBK PAS will also design and manufacture the power supply unit, PSU unit for BOX-W .
