The Evolution of Signal Tracking

SigTrax, now with SigTrax+, makes signal tracking easy and fast.

SigTrax combines the power and visual capabilities of the iPhone and iPad with the accuracy and precision of GPS and mapping to enhance locating signal sources using the triangulation method.

Using SigTrax, manually handling maps, plotting intersection points and determining a route to reach an intersection point is eliminated.

SigTrax simplifies searching resulting in faster, more accurate searches for
ham (amateur) radio fox hunts,
locating signal interference (RFI) or power line noise,
searching for an unlicensed (pirate) radio signal,
tracking near-space balloon flights,
locating transponders,
wild life tracking,
drone tracking
and search and rescue missions.

Requires IOS device with GPS and internet access to obtain map images.
