GNSS / GPS
Loss of satellite lock, degraded positioning or location-dependent tracking problems.
Tracking, telemetry or depot wireless systems behaving unpredictably? We investigate whether the cause is the equipment, the RF environment, local interference or another part of the communications chain.
A tracker going offline does not automatically prove GNSS interference. The fault may involve the antenna, receiver, cellular backhaul, installation, coverage or local RF environment. The investigation should establish evidence before conclusions are drawn.
Loss of satellite lock, degraded positioning or location-dependent tracking problems.
Intermittent trackers where the underlying cause has not been established.
Vehicle or asset data that disappears, becomes unreliable or fails in particular locations.
Wi-Fi, radio or other wireless systems affected by interference or changing RF conditions.
Readers and tags that become unreliable in warehouses, yards or loading areas.
Unexpected transmissions or elevated noise affecting operational radio systems.
We combine on-site RF measurement with practical electronics engineering. The objective is not simply to produce spectrum plots, but to establish the mechanism affecting the system and identify practical corrective action.
Spectrum analysis and appropriate antennas or probes are used to compare normal and abnormal conditions.
Where a measurable interfering source exists, comparative measurements and direction finding can help locate it.
Filtering, shielding, antenna, cabling or other RF engineering remedies can be developed where appropriate.
We discuss the symptoms, affected equipment, location and what has already been tested.
Measure the relevant bands and correlate RF conditions with the reported failure.
Determine whether interference is present and, where practical, identify its source or coupling mechanism.
Provide findings and recommended next steps. Detailed reporting and engineering remediation are available.
See our main RF interference investigation service for source location, wireless fault finding and GNSS diagnostics across commercial and industrial sites.
Describe the symptoms and location. We’ll tell you whether an on-site RF investigation is likely to help.
