OtoSphere™
Industry’s only commercial GNSS protection solution
The innovative device is a small, add-on module to any GNSS-based system that protects it from GNSS jamming attacks.
OtoSphere™ ensures continuity of autonomous navigation and timing signals. OtoSphere™ enables normal operation during jamming conditions. No other solution offers such protection and is as small, light, affordable, and easy to install. OtoSphere™ is unregulated by export control.
​
How does it work?
​
The Vulnerability of GNSS is well known.
Orbiting at 20,000km, the GNSS satellites emit a signal which is incredibly weak when received by GNSS receivers (~-125dBm). To jam or spoof this signal all that is needed is to overpower it.
This can be done with a simple jammer bought online to completely block the signal or with a slightly more sophisticated device that can trick the receiver with erroneous data.
​
Our unique interference filtering algorithm combines the patterns from two omnidirectional antennas.
OtoSphere™ analyzes where the interference is coming from and feeds it into its algorithm to filter out the jamming/spoofing signals.
​
Installation Couldn't Be Easier.
​
After mounting the 2 antennas on a flat, sky-facing, base with at least 10cm separation (optimally > 25cm).
connect the antennas to OtoSphere™ and connect it to the antenna input on your GNSS receiver.
Feed it with power and the system is defended.
