What receivers can I rely on in the vicinity of a GPS jammer?

Selected industrial GPS receivers with advanced built-in technology have proven immunity to all kinds of radio interference. Such receivers have proven powerful enough to work reliably with GPS jammers.

Rugged GPS/GNSS receiver proven to work with simulated interference

Controversy and concern have arisen in the U.S. Congress, the Department of Defense, and many commercial segments that rely on GPS for high-precision positioning and timing applications. Meanwhile, the Federal Communications Commission (FCC) stands by their decision, even if it is safe enough for GPS receivers to continue to operate reliably. So can you count on GPS to continue to provide accurate and reliable positioning, navigation and time?

GPS receiver, strong anti-interference ability

Not all GPS/GNSS* receivers are the same. Selected industrial GPS receivers with advanced built-in technology have proven immunity to all kinds of radio interference. Such receivers have been shown to be robust enough to work together reliably.

Why do people who use GPS/GNSS* positioning technology worry about it? Ligado, a telecommunications company, has been granted the right to transmit signals at frequencies close to GPS signals.

Ligado isn't the first telecom company to challenge GPS receivers. Japanese telecom giant NTT Docomo's 4G signal has been transmitting near GPS frequencies for years, much like how Ligado operates in the US. Septentrio receivers installed across Japan have proven to work robustly despite interference from NTT Docomo's telecommunications towers. High-performance receivers not only ensure accurate positioning in the presence of radio frequency interference, but also ensure high availability in difficult environments, such as close to tall buildings or under foliage. Multiple layers of protection built into the receiver ensure resilient operation for critical applications requiring Assured PNT.
