GNSS / GPS
Positioning degrades or disappears at particular sites, times or operating conditions.
GNSS, RTK, machine positioning or asset tracking failing on site? We investigate the RF environment and affected equipment to determine whether interference is present and what is actually causing the loss of service.
Construction sites are electrically and physically dynamic environments. Machinery, generators, temporary power systems, radio equipment, structures and nearby activity can all change the RF environment. A disciplined investigation separates suspected interference from receiver, antenna, installation and coverage problems.
Positioning degrades or disappears at particular sites, times or operating conditions.
Loss of fix or unreliable precision positioning where the cause is unclear.
GNSS-dependent guidance or control systems become unreliable during operations.
Plant or equipment trackers intermittently disappear or report unreliable positions.
Communication range or reliability changes unexpectedly across a construction site.
Where interference is measurable, comparative measurements and direction finding can help narrow down its origin.
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.
