“…Thus, we present the new mega-constellation services in space paradigm, developed with the support of the European Space Agency (ESA) [19]. The key idea is that megaconstellations, originally designed to offer innovative services to Earth users, can be effectively exploited to connect LEO users, too (Figure 1).…”

“…This approach was also selected so we could perform the link and capacity analysis in the future using stochastical simulations because these analyses involve many statistical effects associated to the communication channel (i.e., fading), resource demand, satellite selection, and network utilisation that inherently depend on the SUT distribution and behaviour (not assessed in this paper). For reproducibility, a sample dataset of the coverage results is available in [29].…”

Mega-constellations are being deployed to offer innovative services to Earth’s users. Our work shows how they can provide seamless connectivity to LEO spacecrafts, too, and transform them into highly responsive space network nodes, thus enabling a myriad of innovative applications. For realizing the new mega-constellation services in space paradigm, in this paper we present a complete design of the LEO space terminal, suitable to any hosting platform, even CubeSats and SmallSats. By focusing on existing mega-constellations, like OneWeb and Starlink, we derive the service performance for four terminal configurations under realistic scenarios and show that Tbit/day- scale capacity is the common case for space users, by constant data dripping. Finally, we compare this new paradigm with existing services like Ground Station Networks and Data Relay Systems. All the results show that the new approach can be potentially disruptive for the space ecosystem, by transforming each satellite into a 24/7 available node characterized by high throughput, low latency, and low cost.

“…This concept was proposed for the first time in our previous work in ( Al-Hraishawi et al, 2021), where preliminary analyses were done. And it gained interest in the field as in (Capez et al, 2023;Gabriel Maiolini Capez and Caceres, 2023), where numerous advantages of the concept are demonstrated and the importance of a study on licensing and legal frequency usage is emphasized. To complement the work done previously, this paper provides a deep analysis on the technology needed on space mission satellites, communication link performance as well as legal aspects related to Radio frequency (RF) usage, including both LEO and MEO SIPs.…”

A satellite internet provider (e.g., Starlink, OneWeb, O3b mPOWR), despite possessing the capability to provide internet services to on-ground users in a global scale, can dramatically change the way space missions are designed and operated in the foreseeable future. Assuming a scenario where space mission satellites can access the internet via a space internet system, the satellite can be connected to the network permanently (24 × 7) and act as mere terminal independently from its location. The ability to communicate with the satellite on-demand has the potential to improve aspects such as real-time tasking, outage minimization, operation cost, and dependency on the ground. This paper performs a feasibility study on the concept of connecting space missions to the network through commercial mega-constellations. This study includes a review of existing and near-future space internet systems, identification of candidate space missions for the aforementioned concept, a necessary adaptation of existing Commercial off-the-shelf (COTS) terminals to be plugged into space mission satellites, assessment of communication performance, and investigation of the legal aspects of the radio frequency (RF) spectrum usage. The paper evidences that the concept is practically possible to implement in the near future. Among the studied space internet systems (i.e., Starlink, OneWeb, O3b mPOWER), O3b mPOWER stands out as the most suitable system allowing permanent coverage of low earth orbit (LEO) space missions with data rates that can reach up to 21 Mbps per satellite. Although the concept is very promising and can be implemented in the near future, our investigations show that some regulatory aspects regarding the RF usage should be solved for future exploitation of connecting space missions through NGSO (Non-Geostationary Satellite Orbit) constellations.
