Briefing
A GNSS-augmented trolley delivering ±0.30 mm gauge accuracy at 4–5 km/h.
Detailed
Overview
The RCI GNSS integrates dual-frequency GNSS receivers (L1/L2) with an IMU to provide absolute position referencing while retaining relative measurement precision. In known network RTK mode, lateral and vertical deviations are constrained to ±20.00 mm and ±30.00 mm respectively—sufficient for line-level geometry validation. The system maintains ±0.30 mm gauge and superelevation accuracy across all speeds from 4 to 5 km/h. It automatically logs track coordinates, generates static TQI reports, and exports adjustment proposals compatible with tamper control systems. Designed for daytime, open-sky operations on mainlines and yard tracks.
Key Components
The GNSS‑based railway track inspection system comprises the following components:
● T‑shaped trolley – mobile platform for the inspection system
● Inertial Measurement System (IMS) – provides core inertial measurements
● Inertial Measurement System (IMS) – provides core inertial measurements
● Sleeper identification and positioning system – identifies sleeper positions and aids in localization
● Ruggedized military‑grade laptop computer – runs the data acquisition and analysis software
● Data acquisition and analysis software – handles real‑time and post‑processing of inspection data
● Global Navigation Satellite System (GNSS) receiver – enables satellite‑based positioning
● Dedicated ballasted track adjustment software – supports adjustment workflows for ballasted tracks

Application Scopes
⚪ Reconstruction of track alignment based on:
The relative displacement data of the existing track geometry,
The smoothness (riding quality) of the existing reference line.
⚪ Guidance for precise and digital tamping operations by large maintenance machinery on lines with unspecified track quality conditions (e.g., BSG, SERUM, RMS).
