Satellite encounters during close operations, such as rendezvous, formation, and cluster
flights, are typical long-term encounters. The collision probability in such an encounter is a …

In this paper, a novel distributed hierarchical control method for small satellites with multiple
disturbances and input constraints is investigated by combining formation flying and satellite …

In space systems consisting of a large number of satellites, coordinating orbits among
satellites is necessary throughout the entire mission lifetime. Although previous works …

The deployer uses a voice coil actuator (VCA) to control precisely the separation velocity of
CubeSats with different masses. This article proposes a novel VCA with a new structure of …

The reachable domain is a geometric description of the maneuverability of a spacecraft
under control and/or measurement uncertainties. In this paper, the reachable domain …

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 …

The high thrust density voice coil actuator (VCA) is a key component for the deployers to
determine the CubeSats' separation velocity in orbit directly. To improve the VCA's thrust …

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 …

A probability threshold is a confidence level defining a bound outside which the occurrence
of a random variable is considered as a rare event. Upon providing such a probability …

利用相对可达区(RRD) 的概念对航天器在脉冲闭环控制方式下相对运动的轨迹偏差进行了分析.
相对可达区是对航天器可能出现位置集合的一种几何描述. 当航天器的状态误差服从高斯分布时 …
