Very low Earth orbit (VLEO) satellite flight, at less than around 450 km altitude, is becoming
increasingly popular. It affords numerous benefits such as increased payload resolution and …

Time-accurate dynamic simulation of objects and spacecraft in rarefied and continuum-
rarefied transition flows during atmospheric entry is computationally challenging. The …

Several small, unconnected satellites flying in formation are a frequently discussed option to
replace large satellites due to advantages such as increased flexibility, reduced costs and …

propulsion (EP) has been successfully used for drag compensation providing long mission …

S debris is the expanding collection of defunct man-made objects in orbit around the Earth.
Collisions of space debris with functional spacecraft can damage spacecraft hardware as …

This chapter will discuss the link between the motion of satellites and thermospheric density
and wind. Section 3.1 will start with a brief overview of relevant theory on satellite dynamics …

Satellite drag coefficients are crucial for accurately computing the orbital path of satellites
and predicting possible conjunctions between satellites. As the number of resident space …

Fourier drag-coefficient models allow higher-order attitude and orbit-dependent frequencies
present in the drag-coefficient to be estimated during the orbit determination process. In …

The estimation and modeling of drag effects on low altitude satellites and debris is a limiting
problem in the prediction of their orbits over time. Independent of the stochastic variations in …
