GPSdome 1.03
DATASHEET

Industry’s Only Commercial
GPS Anti-Jammer
GPSdome is a small-sized, add-on device that provides protection against GPS jamming,
ensuring continuity of autonomous navigation and operation during jamming conditions. No othercommercial solution offering such protection is as small, light, affordable or as easily installed as
GPSdome. Our products are 10x lighter, 15x smaller, 10x less expensive making infiniDome thepreferred choice in anti-jamming solutions.
Features• Null steering technology• Small form factor: 74 x 47 x 25mm, 150g
• Maximum power consumption: <0.8W• IP67, -40°C to +85°C• Protected frequency: GPS L1 (C/A Code)• Passthrough frequencies: GPS L2 & GLONASS G1• Latency: 100ns ± 15ns (fixed)• Insertion loss: ± 2dB
How GPSdome Works

The Vulnerability of GNSS is well known. Orbiting at 20,000km, the GNSS satellites emit asignal which is incredibly weak when received by GNSS receivers (~-125dBm). To jam or spoof
this signal all one must do is overpower it, either with a simple jammer bought online which blocks
it completely or with a spoofer, a slightly more sophisticated signal which can trick it witherroneous data.
The Null Steering Algorithm was originally developed for military applications to protect
wireless signals. GPSdome adds our own sophisticated algorithms and proprietary RFIC todetect suspicious signals, combine antenna patterns and precisely target a null in the directionof the hostile signal.
Installation Couldn't Be Easier. After mounting the 2 antennas on a flat, sky-facing base with atleast 10cm separation (optimally 30cm), connect antennas to GPSdome, connect it to theantenna input on your GNSS receiver, feed it with power and you're set to go.
GPSdome is Completely Standalone. GPSdome is compatible with any GNSS receiver on themarket and compatible with any off-the-shelf GNSS antenna. GPSdome does not include theGNSS receiver or the antennas.
Jamming / Spoofing Detection is available from an LED on the GPSdome itself or via anexternal wire that could be integrated into any system computer. An optional CommModule
could be added to enable attack alerts to be sent to infiniDome’s GPS Cyber Security Cloud.
