Three passive monitoring products for different jobs: a portable warning detector, an unattended detector that can send an SMS alert, and a professional analyser combining RF interference monitoring with live satellite-reception data.
JGD-100 · JGD-110 · JGD-120
The range is deliberately split by application. You only pay for satellite analysis and remote communications when the job requires them.
A compact handheld instrument for quickly identifying abnormal RF energy in the GPS/GNSS L1 region.
Continuous unattended monitoring for vehicles, depots, plant and remote sites. When a significant event is detected, nominated personnel can be alerted by SMS.
An engineering instrument intended to show both the RF interference environment and what is happening to GNSS reception.
A receiver can lose satellites because of shielding, antenna faults, multipath or poor sky view. GNSS Guard Remote and Pro are intended to compare abnormal RF energy with receiver health, helping distinguish an interference event from ordinary reception problems.
Final detection logic, sensitivity and classification thresholds will be published only after engineering validation.
Remote monitoring turns a local warning into an actionable event for a fleet manager, security team or engineer away from the site.
Continuously monitor the relevant RF environment and GNSS receiver condition.
Compare abnormal RF activity with satellite signal quality and receiver performance before escalating an event.
Send a time-stamped warning to nominated personnel, followed by a restoration message when the event ends.
Investigate interference affecting vehicle tracking and positioning.
Monitor sites exposed to intermittent or passing GNSS interference.
Remote warning where GNSS tracking forms part of asset protection.
Monitor the RF environment around GNSS-dependent timing systems.
Investigate unexplained degradation during field operations.
Portable indication and logging for interference surveys.
Identify abnormal GNSS-band RF activity in monitored locations.
Observe receiver behaviour alongside interference measurements.
