We present methodology and mission results from orbit determination of Planet Labs
nanosatellites and differential-drag control of their relative motion. Orbit determination (OD) …

A methodology is presented for the differential drag control of a large fleet of propulsionless
satellites deployed in the same orbit. The controller places satellites into a constellation with …

remote sensing satellite constellations, agile attitude maneuvering is required. By taking into …

In recent years small satellites have shifted from being secondary items to dominate the
space market thanks to, but not only, the development of the large LEO constellations. For …

A growing interest in constellations of small satellites has recently emerged due to the
increasing capability of these platforms and their reduced time and cost of development …

We study the optimal control of an arbitrarily large constellation of small satellites operating
in low Earth orbit. Simulating the lack of on-board propulsion, we limit our actuation to the …

From satellite navigation to weather forecasting, the use of space technology is an
increasingly fruitful part of our everyday lives. A growing contingent of commercial …

This paper presents a framework for the acquisition and the maintenance of ground track
configurations of small Earth observation satellite constellations. Specifically, the relative …

In this paper, we present the project of the heliogyro solar sail unit for deployment of
CubeSat constellation and satellite deorbiting. The ballistic calculations show that …
