“…Telescopes with similar technical features may provide very different performances. We have based our simulations on the following previous work: Olmedo et al (2008), for the definition of the GEO survey, and the GEO and MEO tracking strategies for GB telescopes; Sánchez‐Ortiz et al (2008b), for the definition of observation strategies for SB telescopes; Flohrer, Schildknecht & Musci (2007), for GB telescopes for MEO surveying.…”

A study has been carried out on the capabilities of a potential European Space Situational Awareness System (ESSAS). In this paper we focus on the capabilities of the future system with regards to correlating and cataloguing space debris. Different architectures are proposed and analysed. We report on the performances of these architectures with regards to the observable population, coverage, timeliness of observations, system sensitivity and system redundancy. Preliminary results for the capabilities of the ESSAS show good performances for cataloguing operations. The numerical simulations of the features of a possible ESSAS have been carried out using the Advanced Space Surveillance System Simulator (AS4) developed by DEIMOS Space, under several European Space Agency (ESA) contracts.

“…Space-based sensors have been introduced to support ground-based space surveillance networks [10][11][12], and they turned to be fundamental assets for current and future SSA programs [13,14]. Space-based observations can guarantee better accuracies, versatile field of views and, most importantly, independence from day/night cycles and atmospheric weather conditions, when compared to ground-based optical observations [15].…”

Forecasting of collisions between resident space objects (RSOs) is becoming critical for the future exploitation of near-Earth space. A constellation of 28 spacecrafts (plus in-orbit spares) in sun synchronous orbits is proposed as a solution for improving the current space situational awareness capabilities. Each satellite uses an optical payload to track target RSOs, with the satellite's position precisely determined. Multiple pictures of the RSO are taken, and the spacecraft attitude used to calculate the target's position relative to the spacecraft. The target's orbit is then determined from the movement of the target through the field of view over time. The system outputs orbit state vectors of the tracked object, allowing precise orbit characterisation and collision forecasting to be delivered. The constellation's design allows high temporal resolution, so reliable information can be supplied to end-users. The paper shows the results of the system design of a demonstration mission meant to verify the feasibility of the concept, performed by a team of students of Cranfield University. The exercise addresses all the aspects of the preliminary design, including the definition of the mission and system requirements, the selection of the overall mission architecture, operations, and mission phases. A cap on the overall cost allows for the realisation of the platform within a university budget. The outline of the design includes not only the selection and sizing of all the subsystems and payload but also suggests a new strategy for deploying the constellation if the demonstration mission is successful. The utilisation of high TRL and COTS components, as well as mass, power, and link budgets, demonstrate the feasibility of the overall mission concept.

“…Indeed, uncontrolled objects from the previous space missions are currently occupying important orbital slots, causing notable collision possibilities with operative and non-operative satellites [1]. Despite the recent adoption of some mitigation guidelines [3] and the development of a network of space debris surveillance and awareness [4] [5], the threat of such incidents cannot be totally averted. Collisions, as the one between Iridium 33 and Cosmos 2251 in 2009 [6], are still probable, and they can trigger cascade phenomena that may compromise future utilization of space, labelled as Kessler 1 Associate Professor, University of Alicante, POBox 99, 03080, Alicante, Spain.…”

An image-based servo controller for the guidance of a spacecraft during non-cooperative rendezvous is presented in this paper. The controller directly utilizes the visual features from image frames of a target spacecraft for computing both attitude and orbital maneuvers concurrently. The utilization of adaptive optics, such as zooming cameras, is also addressed through developing an invariant-image servo controller. The controller allows for performing rendezvous maneuvers independently from the adjustments of the camera focal length, improving the performance and versatility of maneuvers. The stability of the proposed control scheme is proven analytically in the invariant space, and its viability is explored through numerical simulations.
