Article
Full-text available
Calculating the projected cross-sectional area (PCSA) of a satellite along a given direction is essential for evaluating the forces and torques induced by atmospheric drag and solar radiation pressure. The PCSA is also required for implementing attitude control modes such as Sun pointing or minimum-drag. This paper develops a new analytical method...

Conference Paper
Full-text available
The concept of flying multiple satellites in formation has evolved to encompass challenging concepts such as disaggregated space architectures and in-orbit assembly, which include very large numbers of modules flying autonomously in a cluster. Whereas control laws for satellite formations are abundant, guidance and control algorithms for operating...
Conference Paper
Nanosatellite clusters constitute one of the current and future trends in space technology. These clusters can be used in a variety of applications including search and rescue, communication, earth monitoring, etc. In order to maintain a satellite cluster over a long period of time it is required that the inter-satellite distances between the clust...

Satellite formation establishment may consume considerable fuel if cross-track distance (CTD) is a mission requirement. This work proposes a strategy for significantly reducing the required fuel. Instead of direct out-of-plane maneuvers, it is suggested to use in-plane maneuvers, while using the nodal precession caused by the J2 perturbation. The C...

Adelis-SAMSON is a nano-satellite mission aimed at performing geo-location of target signals on Earth using a tight three-satellite formation in space. To maintain formation, each nano-satellite is equipped with a cold gas propulsion system. The design, qualification, and integration of the Adelis-SAMSON nano-satellite propulsion system is presente...
Conference Paper
Agricultural engineering is moving towards a future that contains autonomous robots similar to other fields such as the automotive and aerospace industry. Planning systems based on autonomous robots is associated with many challenges in various areas such as navigation, guidance, communication, software, logic, hardware and more. The present work f...

This paper develops cluster control algorithms for the Satellite Swarm Sensor Network project, for which the main aim is to enable disaggregation of space-based remote sensing, imaging, and observation satellites. A methodological development of orbit control algorithms is provided, supporting the various use cases of the mission. Emphasis is given...

DriveSat is a new CubeSat mission, initiated and led by the Asher Space Research Institute at the Technion. DriveSat aims to test low cost Cubesat orbit and attitude control techniques. The mission will demonstrate two new technologies: a miniaturized thruster and a cost-effective reaction wheel, both developed at the Technion. The DriveSat project...

Space Autonomous Mission for Swarming and Geo-locating Nanosatellites (SAMSON) is a satellite mission led by the Asher Space Research Institute (ASRI) at the Technion and supported by the Adelis Foundation. SAMSON includes three nano-satellites, designed by ASRI, that fit into a 6U CubeSat structure and weighs about 8kg. The three satellites will b...

DriveSat is a new CubeSat mission, initiated and led by the Asher Space Research Institute (ASRI) at the Technion – Israel Institute of Technology. DriveSat aims to test low cost CubeSat orbit and attitude control techniques. The mission will demonstrate two new technologies: a miniaturized vacuum arc thruster (VAT) and a cost-effective reaction wh...
Article
Nanosatellite clusters are one of the current and future trends in space technology. To maintain a satellite cluster over a long period of time, the nanosatellites need to mitigate the alongtrack drift created by the initial orbit injection. In the mass range of 1–10 kg, CubeSats have strict constraints on allowed mass, volume, and electrical power...
Article
This paper discusses the feasibility of using drag and solar radiation pressure for a collision-avoidance maneuver. Usually, an alert about possible collision with another satellite or space debris is received a few days in advance, giving ample time to design and perform an avoidance maneuver. For a propulsionless satellite, drag and solar radiati...

Develop new AOCS technologies while taking into account the strict volume and cost limits of CubeSats.
Project
SAMSON will include autonomous 6U cubesats that will demonstrate long-term cluster flight and perform high-accuracy geolocation. Technion's Asher Space research Institute leads the project, with many collaborators from the industry and academia. The launch is planned in 2017. Most of the algorithms (cluster flight, differential drag, geolocation, attitude control) have been designed by Technion grad students.
