Abstract: Recently advanced low-Earth-orbit (LEO) satellite networks represented by large constellations and advanced pay-loads provide great promises for enabling high-quality Internet connectivity to any place on Earth. However, the traditional access-based approach to satellite operations cannot meet the pressing requirements of real-time, reliable, and resilient operations for LEO satellites. A new scheme is proposed based on multi-layer satellite networking considering the advanced Ka-band and optical communications payloads on a satellite platform. The proposed scheme can enable efficient and resilient message transmissions for critical telecommand and telemetry missions through different layers of satellite networks, which consist of LEO, medium-Earth-orbit (MEO), and geostationary (GEO) satellites. The proposed scheme is evaluated in a 24-hr satellite mission and shows superior performance improvements compared to the traditional operations approach.<br />2022 IEEE Latin-American Conference on Communications (LATINCOM), November 30 - December 2, 2022, Rio de Janeiro, Brazil
