How to Use This Calculator
  1. Enter orbital altitude (km) and minimum elevation angle (degrees) for acceptable coverage.
  2. Set orbital inclination (degrees) and coverage overlap margin (%) for redundancy.
  3. Review coverage half-angle, satellites per orbital plane, number of planes, and total satellite count.
  4. Use orbital period and revisit interval to verify coverage continuity meets mission requirements.
  5. Increasing altitude reduces satellite count but increases launch cost and coverage latency.
