International Journal of Satellite Communications and Networking, Volume 41, Issue 1, Page 82-97, January/February 2023., 2023 This paper analyzes which constellation characteristics provide the best global coverage at the lowest operational cost. Our analysis has found that geostationary and medium Earth orbit satellite constellations have the highest likelihood of profitability. LEO networks are more expensive, but if designed wisely, they can be competitive.

International Journal of Satellite Communications and Networking, EarlyView., 2023 In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such
