Introducing the all-new EXPLORER 8100 VSAT

A unique Dynamic Pointing Correction technology and an advanced carbon fiber reflector make the 1 meter EXPLORER 8100 the most advanced Auto-Acquire Drive-Away Land VSAT antenna available.  


Uninterupted Communication


Traditional vehicle mounted ‘Comms-On-The-Pause’ VSAT antennas can lose connection to the satellite with even the slightest movement of the vehicle on its suspension caused by high winds or people getting in and out. EXPLORER 8100 isn’t a traditional land VSAT antenna.

With EXPLORER 8100 you can enjoy continuous connectivity services even if the vehicle rocks thanks to a new and unique ‘Dynamic Pointing Correction’ system. Using lessons learned from Cobham SATCOM’s maritime stabilized VSAT antennas, EXPLORER 8100 offers the most reliable connectivity available in its class. 


Reliable EXPLORER 


EXPLORER 8100 is developed completely in-house by Cobham SATCOM. It features genuine EXPLORER design, which is already established and proven with Cobham SATCOM’s highly regarded EXPLORER BGAN and GX terminals. It is designed to offer unparalleled Comms-On-The-Pause performance, ensuring high-quality connectivity that is available even when other antennas would have lost their connection to the satellite. In the field, this means you can count on EXPLORER 8100 to provide you with vital communications whatever the conditions.

Industry Best

EXPLORER 8100 features industry-leading fast satellite acquisition with pointing achieved typically in less than four minutes, making getting connected to a satellite a quick and easy process. The system is available in both Ka- and Ku-band configurations and works with all major satellite networks. A swappable feed system allows users to change frequency bands, ensuring full choice of what services to use throughout the lifetime of the antenna.
