ITUpSAT1
The mission goals are to capture imagery of the CMOS payload, and to study the behavior of the passive stabilisation system of the CubeSat.It has an SD (Secure Digital) card interface, one Universal Serial Bus (USB) port and external power supply connector.The SPL (Single Picosatellite Launcher) system of Astrofein (Astro und Feinwerktechnik Adlershof GmbH, Berlin, Germany) is being used to deploy the four CubeSats.The launch service interface for all CubeSats is provided by ISIS (Innovative Solutions In Space BV) from Delft, Netherlands.The two payloads share a microcontroller and are physically on the same PCB representing the uppermost circuit of the electronics stack of the satellite.The magnetometer will help to counter the inherent bias and drifts of inertial sensors and provide measurement updates for a filtered and corrected solution of the attitude.The analog-digital conversion of all the sensor outputs is done by a PIC microprocessor which also has the task of grouping the measurements into a packet and sending them over the I²C bus to the on-board computer for downlink transmission.
