How is Iridium Certus different from VSAT?

VSAT and Iridium Certus serve different connectivity needs. VSAT provides high-bandwidth communications over Ku-, Ka-, or C-band networks, while Iridium Certus delivers resilient global connectivity over Iridium's L-band LEO satellite network. With truly global coverage, including polar regions, and strong performance in adverse weather and challenging operating conditions, Iridium Certus is often deployed as a primary mission-critical service or as a backup to VSAT to ensure always-available communications.
Why customers choose both: VSAT delivers bandwidth. Iridium Certus delivers resiliency, mobility, and truly global coverage.
