Q: Is it possible to build a low-cost system to detect and locate a single GNSS jammer in near-real time?
A: GNSS jammers are an ongoing threat to the reliable use of GNSS. The problem of geolocating GNSS jammers can be addressed using a time-difference-of-arrival (TDOA) processing technique; however, this problem is quite different than geolocating jammers in other radio frequency systems. The two main differences are:
(1) No GNSS are available to use as a timing reference.
