“…All such missions need a micro-propulsion system for maneuvering the satellites. Micro-propulsion is a key component since micro/nanosatellites will need a very small and accurate force to attain orbit transfer, attitude control, and station keeping [4,5]. Therefore, MEMS thrusters have been an active research field and various concepts for MEMS thrusters have been investigated.…”

“…For example, several projects at NASA can strongly bene t from the utilization of multiple satellites in orbit: Global Precipitation Measurement Constellation, Leonardo-BRDF, GPS Occultation Constellation, Magnetospheric Constellation, Global Ionosphere-Thermosphere-Mesosphere Constellation, etc. That is why many research institutions, including NASA's Goddard Space Flight Center have been studying and designing and testing tools that enable the use of constellations of small satellites [1].…”

A vision based formation and attitude controller has been derived and simulated for the formation keeping of two 3U CubeSats. Four markers are installed on the leader CubeSat. Two cameras are installed on the follower CubeSat. An efficient vision based pose estimation method is used to estimate the pose of the follower with respect to the leader. A Higher-Order Sliding Mode (HOSM) exact differentiator with finite-time convergence is derived to estimate the rate of the follower’s pose parameters. The follower’s pose and its time rate are fedback to HOSM formation and attitude controllers to correct any gradual drift in formation and pose of the follower. The simulations show the effectiveness of the approach, and its feasibility on existing hardware.

“…consisting of micronozzles and microigniters have great potential applications in the small space vehicles due to their advantages, such as having no movable components and no liquid leakage [1][2][3][4][5][6]. Especially, the MSPT array including multiple thruster units has become more favourable since it can satisfy the flexible thrust configuration requirements [7][8][9][10][11].…”

A silicon-on-insulator (SOI)-based microelectromechanical system solid propellant thruster array is presented. The micronozzle layer and microigniter layer of the array are formed on both surfaces of the SOI wafer, respectively. The layout design rules can properly distribute the heat produced by the microigniter below the solid propellant inside the chamber. Test results show that the highest temperature of the microigniter is located under the propellant. When one unit in the array is ignited by a DC voltage of 7.9 V, other units around it are not ignited. Moreover, the ignition resistors can work again, which means that the array can be used repeatedly when the solid propellant is refilled.
