The following two designs were generated using the
"Continuous Coverage Constellation Design - Advanced Options"
module. Constellation with circular orbits (example
2.1) provides continuous coverage
with a minimum of four visible satellites to any
point on Earth at a minimum ground elevation angle of
0o.
Constellation with elliptical orbits (example 2.2)
provides continuous coverage with a minimum of four
visible satellites to
any point within +20o..+90o
latitude at a minimum ground elevation angle of 0o.
