HK data

One day view plot of housekeeping and ancillary data generated on board the satellite platform.

Panel 1 Status (ON/OFF) of the scientific instruments SWAP, LYRA and DSLP. TPMU is not shown since it is operated directly but via the DSLP DPU unit.

Panel 2 Current consumption of the DSLP DPU unit. Four reference current levels are shown for comparison - SO line ON (red line), DSLP ON (blue line), TPMU ON (green line) and DSLP/TPMU ON (magenta line).

Panel 3 Actual temperature as acquired by two platform sensors related to DSLP experiment - temperature on the deployable back solar panel on which the two DSLP sensors are accommodated (red dots) and temperature on the sensor accommodated on the DSLP DPU unit inside the satellite platform (blue dots).

Panel 4 Raw data from Proba 2 platform magnetometer MM1.

Panel 5 Position of the Proba 2 satellite in the inertial terrestrial reference frame (ITRF).

L0 data

2 hrs summary plot of uncalibrated DSLP measurements acquired on the two main DSLP sensors (GUARD SLPA and GUARD SLPB) with DSLP modes 1-4.

Panel 1 Spectrogram of measured current-voltage characteristics (applied sweep voltage - Y axes; absolute value of measured current - LOG color scale) for segment GUARD SLPA.

Panel 2 Spectrogram of measured current-voltage characteristics (applied sweep voltage - Y axes; absolute value of measured current - LOG color scale) for segment GUARD SLPB.

Panel 3 Measured current level on segments GUARD SLPA and GUARD SLPB for two reference voltages - V_f + 1 V and V_f - 1 V. V_f is the so called floating potential at which the probe collects zero current.

Panel 4 Depending on the data acquisition mode, this panel shows the floating potential (V_f) or the probe to satellite potential (V_S/C) measured either by GUARD SLPA or GUARD SLPB.

Panel 5 Geographic latitude (red line) and longitude (blue line) in the inertial terrestrial reference frame (ITRF).

L0 sweep data

2 hrs summary spectrograms of uncalibrated DSLP current-voltage characteristics acquired on all DSLP segments (depending on the data acquisition mode). Applied sweep voltage - Y axes; absolute value of measured current - LOG color scale.

L1 data

2 hrs summary plot of uncalibrated 20s averadged DSLP scientific products acquired on the two main sensors (GUARD SLPA and GUARD SLPB) with DSLP modes 1-4.

Panel 1 Electron (SLPA blue, SLPB green) and ion (SLPA red, SLPB black) densities in m-3.

Panel 2 Electron temperature in K (SLPA blue, SLPB green).

Panel 3 Estimated floating (zero current) potential on SLPA (blue) and SLPB (green) sensors and estimated satellite potential (with respect to plasma) on SLPA (red) and SLPB (black) sensors.

Panel 5 Geographic latitude (red line) and longitude (blue line) in the inertial terrestrial reference frame (ITRF).
