The Convergence of Remote Sensing, Communication, and Computing for 6G Space-Air-Ground Integrated Networks

Dear Colleagues,

As the trajectory of human mobility continues to expand, the need for communication in deserts, oceans, and other places is also increasing. In this context, global communication coverage can be achieved through 6G space–air–ground integration technology. For the high Earth orbit (HEO) satellites, the transmission delay over long distances has greatly affected the development of satellite communication technology. At the same time, in terms of wide-area Internet of Things (IoT) perception, such as environmental monitoring, smart agriculture, and intelligent power grid, the low Earth orbit (LEO) satellite platform only serves as a collection and return facility for IoT nodes. Massive data still need to be sent back to the ground stations for processing. Meanwhile, detecting and tracking high-mobility targets are not timely enough, and further improvement is needed in terms of low service delay and timely remote sensing information feedback. This requires the guarantee of satellite computing capability. The integration of edge computing technology into the satellite communication network and remote sensing will greatly reduce the service time, improve the quality of satellite communication service, and strengthen the satellite task processing capability so as to enhance the performance of the space–air–ground integrated network (SAGIN) to a greater extent.

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.
