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.
