Constellation Design Examples (page 4)
|
The following two designs were generated using the
"Periodic Coverage Constellation Design / Circular Orbits"
module.
Constellation with circular orbits (example
4.1) provides periodic coverage
with a maximum gap of less than 2 hours to any
point on Earth at a minimum ground elevation angle of
12o.
Constellation with circular orbits (example 4.2)
provides periodic coverage with a maximum gap of 2 hours to
any point on Earth at a minimum ground elevation angle of 20o.
