Trends in Intelligent Road Construction

Road construction evolves toward digital and unmanned operations, supported by policy initiatives and technological advancements.

High-precision GNSS RTK systems provide the foundation for precise control, enhancing efficiency, safety, and data management throughout design, execution, and maintenance stages.

Unmanned Paving Operations

Unmanned pavers require reliable positioning to maintain uniform thickness and alignment.

The X43-N2 RTK receiver paired with JS-HAC148A antenna achieves horizontal accuracy of 0.8 cm + 1 ppm and vertical accuracy of 1.5 cm + 1 ppm. Full-constellation support, IMU for signal continuity, 60 dB anti-interference capability, compact dimensions of 43.8 × 34.0 × 11.5 mm, weight of 25 g, and low power consumption of 0.85 W enable integration in automated systems. This configuration improves surface flatness and operational efficiency by 20%.

Intelligent Compaction Management

Compaction processes benefit from precise path control in unmanned rollers.

The A12 RTK terminal with JS-HAC148A antenna delivers accuracy of 2 cm ± 1 ppm. Features include full-constellation tracking, IMU providing 3-second centimeter-level and 10-second meter-level continuity during signal loss, heading accuracy of 0.15°/R and pitch/roll of 0.25°/R, 4G connectivity, TF card storage, and IP66 protection across -20°C to +75°C. These elements support uniform compaction, multi-machine coordination, and real-time data transmission.

Automated Road Marking

Road marking robots demand high accuracy for compliant line application.

The G27R-3 RTK antenna offers 1.0 cm + 1 ppm accuracy, with errors ≤2 cm at speeds of 5 km/h. It incorporates full-constellation signals, anti-interference design, 20 Hz update rate, IP67 rating, and compact size of Φ128 × 52 mm weighing 291 g. This solution increases efficiency by 300%, minimizes rework, and ensures adherence to standards for safety and aesthetics.

Digital Construction Safety

Safety management integrates positioning for active hazard prevention.

The JS-ARK56-3 module applied to traffic cones provides 1.0 cm + 1 ppm accuracy with full-constellation support, 8-channel anti-jamming filters, compact dimensions of 56 × 56 × 17.7 mm, and low power usage of 12-20 mA. This setup enables real-time alerts and boundary monitoring to reduce on-site risks.

Precision Maintenance and Inspection

Post-construction maintenance shifts toward predictive approaches through accurate data collection.

The X21 receiver combined with JS-HAC148A antenna achieves 0.8 cm + 1 ppm accuracy. Full-constellation and full-frequency tracking, IMU with 0.2° heading precision, 4G communication, 10 Hz update rate, and dimensions of 75 × 50 × 12.8 mm weighing 61 g facilitate efficient patrols. This system triples inspection efficiency and supports precise damage localization.

These GNSS RTK solutions from JUMPSTAR contribute to enhanced precision, operational efficiency, and digital traceability in modern road construction projects.
