GPSdome is a small sized add-on device that provides protection against GPS jamming and spoofing GPSdome ensures continuity of autonomous navigation and enables operation during jamming and spoofing conditions. No other solution that offers such protection is as small, light, affordable or as easy to install as GPSdome. Applications With GPS being the corner-stone of aerial navigation, Unmanned Aerial Systems (UAS) are completely disabled in the presence of a simple GPS jammer that today is available online for less than $50. Designed with drones and small UAVs applications in mind, GPSdome is suitable for a wide variety of UASs as well as other GPS-dependent applications. GPSdome is a small sized, light weight, low powered solution suitable to be retrofitted to protect any navigation system. With GPSdome's protection, any UAV or drone immediately becomes more robust and protected against wireless attacks.

How Does It Work?
The Vulnerability of GPS is well known. Orbiting at 20,000KM above sea level, the GPS satellites emit a signal which is incredibly weak when received by GPS receivers (~-125dBm). To jam or spoof this signal all one has to do is overpower it. Either with a simple jammer bought online which blocks it completely or with a bit more sophisticated HW which can trick it with erroneous data. The Null Steering Algorithm was originally developed for military applications to protect wireless signals. By combining the patterns from both antennas, GPSdome detects where the interference is coming from and creates a new antenna pattern which nullifies the power of the interference. Installation Couldn't Be Easier - After mounting both antennas on a flat, sky facing base at least half a wave-length apart (10cm minimum, 20cm is optimal), connect antennas to GPSdome, connect it to the antenna input on your GPS receiver, feed it with power and you're set to go. Jamming / Spoofing Detection is available from an LED on the GPSdome itself or via an external wire that could be integrated into the UAS computer.
