Viasat’s Ken Buer on phased array antennas

April 19, 2022

How the technology and a growing global network position Viasat

In this episode of the Viasat Podcast, host Alex Miller talks with Ken Buer, chief technical officer for our Viasat Arizona office, about phased array antenna technology and the shift to Commercial Satellite Internet (CSI) applications. As Buer explains, CSI is a pivot away from purpose-built satellites, such as those created by the U.S. Government, to a model where commercial satellite operators such as Viasat provide a more economical solution that also affords customers the latest, updated technology and a global network. He also details how phased array antennas with beam-forming capabilities will be key to realizing the most benefit out of CSI.

Topics discussed in this podcast episode:

  • CSI improvements via a new generation of phased array antennas, which have the ability to electronically form beams to work with multiple satellites as well as for moving objects such as planes, ships and trains
  • How several locations within Viasat are collaborating on phased array antenna designs aimed at improving their performance as well as reducing their cost
  • How flat-panel phased array antennas can be ideal for things such as fighter aircraft, where the ability to move the antenna quickly is vital and the low-profile design reduces drag
  • Viasat’s vertically integrated model and how Buer, as a system designer, says it give him the freedom to better optimizing how software is integrated with hardware
  • The company’s ability to provide end-to-end security and capability
