Anti-jam systems: Which one works for you?

June 14, 2017By

In my April column, I introduced the basic concepts behind GPS anti-jam technology, along with a bit of history around its evolution. I knew this was a popular topic, but I didn’t anticipate the enormous amount of positive correspondence I’ve received since, including many inquiries about where to buy this technology and who is entitled to have it. So this... read more

Anti-jam technology: Demystifying the CRPA

April 12, 2017By

Controlled reception pattern antennas (CRPAs, pronounced “serpers”), adaptive antennas, null-steering antennas, beamforming antennas… You’ve probably heard of at least one of those terms in any discussion around GPS anti-jam technology for defense. Because they are all terms that describe essentially the same thing: a specialized antenna that helps protect GPS receivers from interference and jamming. But what exactly are they? Where... read more
