Glocom Gemini 128

Gemini-128 is an Inmarsat land transportable, dual-channel terminal capable of low-rate telephony (secured and regular) and high-speed ISDN data services up to 128 kbps. The terminal functions under Inmarsat global area network (GAN) via Inmarsat 3rd and 4th generation satellites for worldwide coverage.

Gemini-128 dual-channel design provides convenience for users to operate two service modes simultaneously (e.g. voice and G4 fax; file transfer and teleconference, etc.). Gemini-128 will also be available for Inmarsat lease service under I-3 satellite network.
