Checking Availability
Availability is determined using the latest orbit data. If the TLE changes, then so do the available upcoming passes.
Requesting Available Passes
A list of available passes can be obtained from all StellarStation interfaces. Related information can also be found for each pass such as the ground station name, location, estimated AoS, estimated LoS, channels, and more. From this, satellite operators then reserve the needed pass as a plan.
Unavailability
Ground stations may have blocks of unavailability in their schedule.
Even if the satellite is visible during such a time, if the ground station is unavailable at that time, then the pass will not be available for reservation.
Even if the satellite has a reservation at such a time, if the ground station becomes unavailable at that time, then the plan will be canceled or marked as in-conflict.
Unavailability may occur...
- Due to a higher priority reservation being created
- Due to a higher priority reservation drifting into the desired time
- Due to outages
- Due to scheduled maintenance
- Due to emergency operations
Priority
Satellites on the ground segment have varying levels of priority. Consult your contract for more information about your mission's priority level and contact Infostellar staff if you have any questions.
Conflict
Another high priority reservation or ground station unavailability may conflict with an existing reservation. In this case, the affected reservation becomes "in-conflict". At this point, the satellite operator can either wait to see if the conflict is resolved by the other party, or reschedule the reservation.
