Design of MEMS Based Attitude Determination and Control System for Nanosatellite
-One of the latest manifestations of miniaturization in space applications is the development of standardized nanosatellite. Recent achievements and future trends of Micro-Electro-Mechanical Systems (MEMS) technology have indicated that microtechnology is the critical technologies of future space programs. Enabling technologies for demanding applications will surely make use of MEMS based compo...
متن کاملAas 03-100 Integrated Orbit and Attitude Control for a Nanosatellite with Power Constraints
Small satellites tend to be power-limited, so that actuators used to control the orbit and attitude must compete with each other as well as with other subsystems for limited electrical power. The Virginia Tech nanosatellite project, HokieSat, must use its limited power resources to operate pulsed-plasma thrusters for orbit control and magnetic torque coils for attitude control, while also provi...
متن کاملAttitude and Orbit Control of Small Satellites and Constellations with FEEP Thrusters
L OW thrust electric propulsion systems find a promising application field on small-to-medium sized spacecraft, with mass ranging from a few hundred to about 1000 kg and orbital altitudes of 700 km or higher, like those envisaged for most of the proposed LEO telecommunication constellations. To evaluate the performance of FEEP for such missions, a study was carried out on a typical attitude and...
متن کاملChopper-modulated gas chromatography electroantennography enabled using high-temperature MEMS flow control device
We report the design, fabrication and characterization of a microelectromechanical systems (MEMS) flow control device for gas chromatography (GC) with the capability of sustaining high-temperature environments. We further demonstrate the use of this new device in a novel MEMS chopper-modulated gas chromatography-electroantennography (MEMS-GC-EAG) system to identify specific volatile organic com...
متن کاملDimensionless Performance Model for Gas-Fed Pulsed Plasma Thrusters∗
We present a non-dimensional gas-fed pulsed plasma thruster performance model. The analysis uses a circuit element discharge description and a snow-plow mass accumulation model with two non-dimensional parameters for an outer electrode geometry contour and an exponential mass distribution. Implementing a non-dimensional scheme is shown to reduce the number of free parameters in the equations fr...
