Terms of use
Free to use, provided as-is, and not suitable as the basis of a commitment anyone will rely on.
Nature of the output
This site produces planning-grade estimates from a simplified geometric model. The model, its sampling and its exclusions are described in full on themethod page. Results are approximations intended for sizing and for early commercial reasoning.
No warranty
The calculator and its content are provided without warranty of any kind, express or implied, including any warranty of accuracy, completeness, fitness for a particular purpose or non-infringement. Use of this site is at your own risk.
Not for contractual or operational use
Output from this site must not be used as the basis of a service level agreement, a coverage commitment, a regulatory filing, a safety-related decision, or any operational plan. Work of that kind requires full-fidelity analysis with real ephemerides, link budgets and validated tooling. No liability is accepted for any loss arising from reliance on these figures.
No affiliation
This site is independent. It is not affiliated with, endorsed by or sponsored by any satellite operator, manufacturer, agency or software vendor. No operator data is ingested, and nothing here is derived from any operator's telemetry, ephemerides or internal figures.
Some pages describe constellation shapes: publicly documented shell parameters such as satellite count, altitude, inclination and plane count, flown as an idealised Walker-delta constellation. Where such a shape is associated with an operator by name, the name is used descriptively to identify a widely published geometry and nothing more. These pages do not model any operator's actual constellation, do not describe any operator's actual service, and must not be read as a statement about the performance, coverage or capability of any real system. Real fleets differ from their design geometry in every respect that matters.
Content
You are welcome to use figures from this site in your own work, including presentations and internal documents, provided you state that they are planning-grade geometric estimates and do not present them as validated coverage analysis. Attribution to revisittime.com is appreciated and not required.
Availability
The site is offered without any guarantee of availability, and may change or be withdrawn at any time. Shared configuration links depend on the site remaining online.
