Answer.
An ATO (Authority to Operate) is a single agency's risk-acceptance decision for a system under RMF (SP 800-37). A FedRAMP authorization is a standardized cloud-service authorization — via the program's baseline and continuous monitoring — that other agencies can reuse, avoiding a fresh review per agency. FedRAMP is essentially a reusable, cloud-specific ATO. Planisphere supplies measurement evidence that informs either decision; it is not itself an authorizing official.
