    v1 v2  
    1919 *  To gain positive publicity for space research in Finland and Europe
    2020 *  To gain valuable experience of space related projects

     25The experiment consists of three units. Supikoira flight computer 2 (SFC2), Inertial Measurement Unit 2 (IMU2) and the Experiment Digital Camera (EDC). The SFC2 will record inertial measurement data from IMU2 and images from the EDC. IMU2 data will be recorded to onboard memory and the images will be recorded on external SD memory card.
     26=  Communication  =
     27
     28
     29SFC2 and IMU2 will be communicating over MIL-STD-1553 Bus. SFC2 and EDC will be communicating over Ethernet and a couple of digital IO lines. SFC2 will be also communicating to the ground station via radio uplink and downlink provided by the REXUS rocket. The REXUS communication is going over RS-422 serial link.

     36Software consists of three distinct parts:
     37
     38''' 1. SFC2 software'''
     39
     40 *  Operating system: RTEMS
     41 *  HW drivers (UART, Clock, Timer, RTC, SD/MMC, MIL-STD-1553, Ethernet)
     42 *  Navigation software
     43 *  Logging
     44 *  MIL-STD-1553 bus controller
     45 *  Camera control
     46 *  Uplink/Downlink
     47 *  HW drivers written in C, other software in Ada95
     48
     49'''2. IMU software'''
     50
     51 *  Measures accelerations, angular velocities and sensor temperatures.
     52 *  Does sensor error compensation.
     53 *  Does integration of inertial measurements
     54 *  MIL-STD-1553 remote terminal
     55 *  Written in C
     56
     57'''3. Ground software:'''
     58
     59 *  Flight visualization
     60 *  Logging
     61 *  Written in Python/C/Ada95
     62
     63With the exception of MIL-STD-1553 driver, software is developed on Embedded Artists LPC2468 prototyping board, while waiting for the actual hardware to finish. Navigation algorithms are prototyped with Python / Numpy, before implementation in Ada95.
