Ground radar vs optical telescopes vs space-based sensors for debris tracking: accuracy and coverage compared

Compares three primary orbital debris tracking approaches: ground-based radar (US Space Surveillance Network tracks 27,000+ objects ≥10 cm), optical telescopes (effective for GEO debris down to 1 m), and emerging space-based sensors (capable of detecting sub-centimeter fragments). Evaluates detection thresholds, catalog accuracy, latency, and cost per tracked object.

Orbital debris mitigation compliance guide: navigating IADC guidelines, FCC 5-year rule, and ESA Zero Debris Charter

Maps the evolving regulatory landscape for orbital debris: the FCC's 2024 rule shortening post-mission disposal to 5 years, IADC's 25-year guideline, ESA's Zero Debris Charter targeting zero new debris by 2030, and France's LOS Act requiring disposal plans. Covers compliance obligations for constellation operators launching 100+ satellites annually.
