Analysis of Key Technologies for Uplink Control of Planetary Deep Space Exploration

This study addresses critical uplink control challenges in deep-space planetary exploration, including Telemetry, Tracking, and Command (TT&C) constraints, relay transmission dynamics, and extreme signal delays (>40-min round-trip delay, RTD). Focusing on Mars exploration missions, we extend planetary exploration technologies to develop an integrated uplink architecture featuring: Command-Data Frame Integration (CDFI), Space-Ground Collaborative Control (SGCC), Deep-Space Relay Transmission (DSRT), and Holistic Multi-Tiered Verification (HMTV). Validation demonstrates 63.2% latency tolerance improvement and 99.94% command reliability at 3.7 Astronomical Unit (AU). The framework establishes a technological foundation for ultra-distance exploration (>5 AU).
