However, factors such as manipulator joint/actuator friction and spacecraft attitude control thruster inaccuracies can substantially degrade control system performance.

Would accommodate the small satellite's power, mass and size constraints while meeting the objectives of the mission. In addition, Andrews and ISIS are both developers of CubeSat and NanoSat subsystems, including the Andrews 100 Series of avionics components and the ISIS line of radios, power system elements, spacecraft structures and the ISIPOD in two classes: the SENTRY for 3U and 6U CubeSats weighing up to 10 kg, and the SENTRY XP for nanosats weighing up to 40 kg that require an advanced attitude determination and control system and high power capabilities. Spacecraft Attitude Determination & Control. The functions of a regular satellite would be partitioned in a System F6 model, with the power, receiver, control, computing, payload functionality and ground communication capabilities housed in separate modules. The students divide themselves into one of several teams, including: Attitude determination and control. V0=magnetometer bias =the net local magnetic intensity in body coordinates. The Attitude Determination and Control unit uses a variety of sensor readings to orient the satellite in space to conduct the spectroscopy experiment. Attitude determination and control. The tracking part of the subsystem determines the position of the spacecraft and follows its travel using angle, range and velocity information. The telemetry part gathers information on the health of various It also provides attitude control, which is essential to prevent the satellite from tumbling in space and also to ensure that the antennae remain pointed at a fixed point on the Earth's surface. The spacecraft was built by Orbital Sciences Corporation, and its design is based on the company's LEOStar-2 bus. Payload - accomplishes mission specific tasks and varies greatly between missions.

A 2-way optical communication terminal occupying 1U is based on JPL The final 1U is used for satellite housekeeping (C&DH, power, attitude determination) and based on CalPoly CP7 and JPL CubeSat On-board processing Validation Experiment (COVE) avionics. The solar sail is based on the Planetary Society/Stellar Exploration LightSail™ 1, plus electrochromic tips for attitude control.
