Smart Nanosatellite Attitude Propagator

Performance testing of a microfabricated propulsion system for nanosatellite applications

There is a growing interest in the use of micro and nanosatellites within the aerospace community. Constellations of small satellites may eventually replace much larger, single function spacecraft as a cheaper, more flexible alternative. Micro-technologies will be required to enable small satellite missions including efficient, low-cost propulsion systems for maneuvering. A MEMS fabricated prop...

A Novel Adaptive Unscented Kalman Filter Attitude Estimation and Control System for a 3U Nanosatellite

A novel adaptive unscented Kalman filter (AUKF) based estimation algorithm is proposed for a 3U Cubsat. This small satellite employs a three axis magnetometer and three MEMS gyroscopes as well as three magnetic torque rods and one reaction wheel on the pitch axis. Unlike the existing UKF, in this paper, an n+1 sigma set is used to estimate the nanosatellite attitude instead of 2n + 1 sigma poin...

We studied the possibility of the high brightness operation of the NewSUBARU electron storage ring without lattice modification. By turning-off the RF shaker that is used to enlarge the vertical size and the lifetime of stored electron beams, the brightness can be improved 2.7 times assuming that the stored current is the same. As the lifetime decreases, the top-up current is also reduced due t...

Autonomous Operations Experiments For the Distributed Emerald Nanosatellite Mission

Distributed space systems are often cited as a means of enabling vast performance increases ranging from enhanced mission capabilities to increased system flexibility. Achieving this vision, however, will require radical advances in the automated control of these multi-satellite systems. To explore this challenge, Santa Clara University and Stanford University have initiated development of a si...
