CONCERNING THE SPACE EXPERIMENT WITH SCIENTIFIC GEAR MRT ON SPACECRAFT ”FOTON-M” № 4

The short description of scientific equipment of МРТ (multichannel recorder of temperatures) is resulted and experimental results about current temperatures in local zones of containers of the scientific equipment, received in 42 daily flight of a space vehicle ”FOTON-M” № 4 are presented. It is shown, that the most essential factors defining a thermal mode in containers of scientific equipment, their position on the external surface of the spacecraft, focused almost during all flight by panels of solar batteries on the Sun and conditions on coils or, that’s the same, current deviation of a normal to a plane of orbit spacecraft from a direction on the Sun. Thus time numbers of data about values of temperatures have strongly pronounced oscillatory character with the orbital period of movement of spacecraft and with high level of correlation between them, and also dependence values of temperatures from the position of a plane of orbit of a spacecraft concerning the Sun.

Multi Channel Recorder for Unmanned Aerial Vehicle Based on ARM9

For accessing data from different channel in UAV (unmanned aerial vehicle) immediately, a method for massive data and multichannel recorder system is introduced. The system hardware composition and functions are described in details. The software design of receiving program is given, including extended UART ports’ initialization and design of interruption scheme. And experiment result shows that the recorder not only record data from UAV successfully but also improve the way to hand the UAV data.
