SkyMAX Mobile Satellite Services

Robust Communications When and Where You Need Them

Knight Sky's Mobile Satellite Service solutions are fully turn-key, managed solutions via our own SkyMAX™ network. SkyMAX Mobile Services are designed for end-users that require a flexible managed network service for voice, video, and data applications, independent of terrestrial infrastructure. Knight Sky's Network Operations Staff manages all application services, such as VoIP, RoIP, and VTC, as part of the comprehensive end-to-end service.

Satellites Orbiting EarthKnight Sky's SkyMAX network provides Voice over IP (VoIP) coverage to the entire continental United States as well as Hawaii and Puerto Rico. Within that range of geographic locations, VoIP services are provided with no long distance charges. Knight Sky can supply 10 digit DID telephone numbers provisioned with local exchanges within the service area for the customer's satellite terminals, which limits potential long distance charges being engendered on the customer's terrestrial network-based originated calls to the VoIP phones operating via the satellite terminals.

We also provide personal mobile communications services such as Inmarsat BGAN and IsatPhone, Iridium handhelds, and Thuraya IP/XT, enabling truly global coverage to meet your most demanding communications needs.
