Behavioural Characterisation of Resident Space Objects for Space Situational Awareness

Dear Colleagues,

The proliferation of space objects, i.e., the advent of small satellites and mega-constellation, poses significant challenges to space traffic management and highlights the need for a better understanding the behaviours of both operational satellites and nonoperational space debris in order to build up & maintain a catalogue and eliminate the risk of space collisions. Space tracking, target detection & identification, and state estimation are essential tasks for behavioural characterisation of such objects in the context of space situational awareness.

This Special Issue aims at addressing a wide spectrum of technical issues in space tracking, object detection, orbit/attitude determination, manoeuvring detection and estimation for residential space objects, which connect the fields of measurements, modelling, dynamics for space situational awareness applications. Topics may cover anything from ground tracking capabilities to space-based detection and estimation, from single orbit determination to multiple target tracking, etc.

Articles may address, but are not limited, to the following topics:

• Space object detection from optical sensors
• Initial orbit determination and orbit determination
• Intelligent attitude determination and control
• Data aggregation and fusion, e.g., angular/range/doppler measurements
• Robust manoeuvre detection and estimation techniques
• Space tracking and data correlation
• Cislunar space situational awareness

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
