Investigation of microgravity environment on board ISS using convection sensor DAKON-M

We describe the results of the experiments with convection sensor DAKON-M, installed on board the International Space Station(ISS).The measurements of the sensor and the quasi-steady accelerations, constructed in the point of its installation, were compared. For comparison 3 segments, obtained during the experiments in 2009, were selected. On these segments the dynamical operations of the dockings, undocking and the Service module engines burns were carried out. For the acceleration constructing the measurements of the low-frequency accelerometer MAMS located on board the ISS American segment and the telemetry information about the stations angular motion were used. The data allowed recalculating the MAMS measurements into the point of the convection sensor DAKON-M installation. The comparison of the sensor measurements and the constructed accelerations shows the certain coincidence that allows drawing a conclusion about availability of using sensors of such kind for quasi-steady accelerations monitoring.
