GNSS RTK surveying often faces frequent issues including parameter errors, elevation mismatches, signal disconnection and positioning failures. These common faults greatly reduce field work efficiency and compromise survey data accuracy.

Elevation deviation is the most prevalent accuracy problem in RTK field operations.

Incorrect Pole Height Input for Control Points<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Inconsistency between the actual pole height and the manually entered height in the controller software causes systematic elevation offset. The system calculates elevation data based on wrong parameters, leading to overall height deviation of all surveyed points.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Solution:<\/strong> Create a new project and recalculate conversion parameters. Double-check the actual pole height and software input data during control point collection to ensure full consistency before saving points.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Manual input errors of control point plane coordinates and elevation values are major human errors. Confused point data or wrong numbers directly invalidate conversion parameters and cause uniform elevation deviation across the survey area.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t

Solution:<\/strong> Delete faulty parameters and build a new project for re-calculation. Verify all coordinate and elevation data against official control point records to eliminate manual entry mistakes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Unstable elevation jump and random deviation usually occur when the fitting model fails to match the number and distribution of control points. This issue persists even after excluding manual input errors in field operations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Solution:<\/strong> Re-solve parameters in a new project. Adopt plane fitting with 3 control points for small flat areas, and surface fitting with 6 control points for large or undulating terrains to ensure precise elevation fitting.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Why Regional Custom Conversion Parameters Are Mandatory for RTK<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Raw RTK WGS84 geodetic coordinates cannot be directly applied to engineering construction, land surveying and layout tasks. Most domestic and industrial projects require conversion to BJ54, XIAN80, CGCS2000 or custom construction coordinates.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

No universal national conversion parameters exist for different ellipsoid datums. WGS84 differs from traditional coordinate systems in axis offset, rotation angle and scale difference. Generic parameters will cause severe positioning errors due to regional ground network systematic deviations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t

Custom regional parameters calculated via local common points ensure accurate conversion from satellite coordinates to engineering coordinates. Reasonable quantity and geometric distribution of control points effectively improve overall coordinate transformation precision.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

When no control points are available for calibration, three practical methods can verify RTK hardware accuracy and stability. All tests must be conducted under a stable RTK fixed solution state for valid results.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Incorrect manually input known point coordinates or inaccurate official reference data cause coordinate mismatch. The meter-level WGS84 single-point data cannot match precise adjusted control point coordinates and fail parameter matching.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Missing conversion parameter configuration is another key cause. The controller only recognizes raw WGS84 data without valid plane coordinate conversion parameters, resulting in continuous single-point positioning failure.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Local Deviation After Point Calibration<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Irregular linear distribution of control points and survey areas beyond point coverage lead to partial coordinate deviation. Long-distance control by sparse points also causes uneven overall survey accuracy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Arrange control points evenly around the survey area to form a closed coverage. Conduct zoning calibration and parameter calculation for large terrains to guarantee uniform precision across the entire working range.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Excessively long baseline distance, insufficient visible satellites, low signal SNR and antenna interference delay RTK initialization, seriously affecting field work progress and efficiency.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Shorten the baseline between base and rover. Enable multi-GNSS star positioning. Remove peripheral interference sources and check antenna connection to ensure unobstructed satellite signal reception.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Core Principles for RTK Survey Accuracy & Stability<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Over 90% of RTK accuracy faults stem from wrong parameter settings, unreasonable control point layout, poor network debugging and human errors. Standardized operation habits effectively reduce most field equipment failures.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Always calibrate parameters and inspect device status before surveying, and double-check data before archiving. This standardized workflow ensures consistent, accurate and valid RTK survey results for all engineering projects.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
