Suitable for track precision measurement based on GNSS reference station control network; At the same time, it is also suitable for the survey of the railway line overhaul.
GNSS Inertial Navigation Type Orbit Geometry Measuring Instrument (AIS800G) is a fast and mobile precision measurement product of orbit geometry using Beidou and GPS assisted inertial navigation system. The biggest highlight of the product is that the "absolute + relative" measurement of the universal speed railway track is completed based on satellite control and GNSS reference station.
Novel operation mode
The combination mode of GNSS plus inertial navigation is innovatively introduced into the existing line track inspection, which is simple in field operation, fast in hand, and does not require professional training.
Quick and easy operation
Products adopt modular design, easy to disassemble and assemble on the road; The software interface is simple and friendly, one-click data processing, and fault-tolerant mechanism is perfect.
High measurement accuracy
System gauge, ultra-high repeatability detection accuracy up to 0.2mm, track, high and low, long and short wave irregularity repeatability up to 1mm repeatability measurement accuracy, based on CPI/CPII/ global coordinate system absolute detection accuracy up to 15mm.
High measurement efficiency
The measurement operation can be completed by implementing the equipment on the track, and the implementation speed is not more than 20km/h, with no low speed limit. Each skylight can operate 6~10km (push, 2 hours skylight).
Advanced data processing
With high precision inertial navigation system as the core, advanced multi-source data fusion technology is applied to achieve centimeter-level absolute detection accuracy and submillimeter-level relative detection accuracy in dynamic mode.
Strong adaptability
The system has good adaptability to climate and mechanical structure.
