ESAs are software controlled to instantaneously track and connect highly mobile users to GEO, MEO and LEO satellites. Our ESA technology is interoperable across satellite networks and can be adapted to land, air and maritime platforms.

The ESA Value Proposition:

•    Delivering low profile, high bandwidth terminal solutions to mobile platforms 
•    Electronic beam steering improves communication reliability by eliminating mechanical moving parts 
•    Keeping mobile platforms locked onto the satellite in the most extreme environments, ensuring high performance communications
•    Instantaneously electronic beam switching between satellites enables the next generation of Low Earth Orbit/Medium Earth Orbit (LEO/MEO) constellations 
•    Supporting communications requirements of today and tomorrow with a singled future proof antenna

Ku- and Ka-Band SATCOM Antennas and Terminals
KU device housing

Ball Aerospace's Ku- and Ka-Band phased array antennas feature our innovative subarray antenna architecture. The subarray is an environmentally-sealed ESA building block. The image to the right shows a subarray with its housing facing up. The opposite side of this subarray has the radiating elements and integrated radome. A terminal's transmit and receive antenna sizes are optimized by tiling multiple subarrays together to meet requirements as shown in the figure below. 

Ball Aerospace’s subarray architecture brings affordable ESA technology to the SATCOM market. Affordability is achieved through our innovative architecture and manufacturing scale. Our subarrays are fully electronic with no unique materials or complex assembly processes. This allows the antennas to be assembled in volume, minimizing cost. The subarray architecture drives economies of scale for all users, cost is driven down as volumes increase. The subarrays support both military and commercial use cases, including in-flight connectivity (IFC), communications on the move (COTM) and communications on the pause (COTP).

In-Flight Connectivity

Revolutionizing Airline Connectivity

Ball ESAs Support Alaska Airlines

Intelsat was selected by Alaska Airlines to implement in-flight Wi-Fi using Ball’s electronically steered antenna (ESA).

In-flight Connectivity Demo

OneWeb and Stellar Blu Solutions successfully delivered broadband in-flight connectivity to a commercial aircraft via low-earth orbit (LEO) satellites and a Ball-built electrically steered antenna (ESA).

New In-Flight Connectivity Solution

Intelsat launches new IFC solution for airline customers using Ball Aerospace’s electronically steered antenna (ESA) technology to enable flexible access to GEO and LEO satellites.


To keep costs low, we leverage commercial off-the-shelf technologies and processes. The sub-arrays utilize highly integrated semiconductor devices and standard circuit card materials, avoiding unproven materials. The resulting sub-arrays are designed for high-volume manufacturing and are produced like any other electronics communication equipment. By leveraging high volume contract manufacturing facilities and design for manufacturability expertise, cost is driven down as volumes increases. Having a standard building block drives economy of scale for all users.
