Relative navigation is a key enabling technology for space missions such as on-orbit
servicing and space situational awareness. Given that there are several special advantages …

The most complete description of the state of a system at any time is given by knowledge of
the probability density function, which describes the locus of possible states conditioned on …

Leveraging space-based optical platforms for space debris and defunct spacecraft detection
presents several advantages, including a wide detection range, immunity to cloud cover …

SITUATIONAL awareness of Earth-orbiting particles, such as active satellites and space
debris, is highly important for all current and future space-faring nations. One topic of recent …

Measurement association and initial orbit determination is a fundamental task when building
up a database of space objects. This paper proposes an efficient and robust method to …

This paper presents a novel method to obtain the solution to the initial orbit determination
problem for optical observations as a continuum of orbits—namely the orbit set—that fits the …

This paper proposes three Sun-Synchronous Orbit (SSO) Space-Based Space Surveillance
(SBSS) optical constellations with the intention of building up and maintaining a catalog of …

This paper investigates the satellite formation-containment flying control problem to handle a
scenario where a group of satellite effectively completes deep-space exploration. In such a …

Admissible region methods for initial orbit determination are generally implemented without
considering the contributions of uncertainty in observations or observer state when …

Sparse observations make single-point track initialization difficult in some multitarget
tracking scenarios, including space-object tracking. A probabilistic admissible region …
