What are Unavailability Windows?
Ground station owners may preserve the exclusive right to use its own ground station by creating an "Unavailability Window" in StellarStation. Satellite operator cannot make a reservation of a pass when the period of the pass is covered by Unavailability Window. In other words, passes that is not covered by the period of Unavailability Window will be offered to satellite operator for reservation.
Ground station owners are requested to set unavailability windows before the satellite operator books their passes. You can set an unavailable window from 10 minutes later and beyond. On the other side, satellite operators with on-demand service can book their passes up to 7 days ahead, and satellite operators with reservation services can book up to three weeks ahead. You are able to cancel the booked pass if necessary, but the cancellation of a booked pass from the ground station owner is charged a penalty fee.
Access to Ground Station Console
Ground station owner can manage own unavailability windows through ground station console, CLI (Command Line Interface), or API (Application Program Interface).
The simplest way to manage the unavailability window is through ground station console. If you have not signed up StellarStation, or if you have not been allocated to your organization, please ask firstname.lastname@example.org to make your account allocated under the designated organization group.
