PostHeaderIcon New subsystem evaluation boards

New evaluation boards of various subsystems are ready. From left to right:
Solar charge controller, 12V-Boost-Converter for radio power stage and valves, source drivers, motor controller for reaction wheels, radio transceiver

PostHeaderIcon RCS & IMU module (rotation/acceleration/reaction control subsystem)

Rotation rate estimation for our RCS+IMU (reaction control system/inertial measuring unit)
The module includes a 3-axes rate gyro, 3-axes accelerometer and control hardware for microthrusters.
It will work together with the optical navigation module, reaction wheels and thrusters beeing able to determine its attitude and position in space, tracing its flight path and perform desaturation and midcourse corrections.
Fixed point arithmetic on quaternions and kalman filters will be used for fast and accurate calculations. (Paul Kocyla Sep2011)

PostHeaderIcon Lecture on Plasma Electrolysis Propulsion

Desktop Delta-V workshop in Providence, RI

Paul Kocyla joined the Desktop Delta-V workshop this year. The topic was safe propulsion for small spacecrafts.
He gave a lecture on plasma electrolysis propulsion for cubesats.
