Identification and location of steel coils using the GNSS system with RTK correction

Resumo

The precision, repeatability, and accuracy of the system were measured in order to verify if it is possible to

identify a coil stored in the yard through its geospatial position. To obtain the desired result, it was necessary to de-
velop a hardware that allows tracking the forklift using real-time kinematic correction, also known as GNSS-RTK.

The proposed system had a base station communicating directly with one or more rovers, sending data through the
RTCM protocol to perform correction calculations based on the received information. After the development of
the hardware and validation tests in the laboratory, the hardware was installed on forklifts with load capacity of 40
tons that operate in a real coil production and storage environment. The average weight of the coils operated by
forklift machinery was 20 tons. This manuscript communicate the real results of the identification and location of
steel coils procedures by using GNSS-RTK. The tests were carried out in a large-company producer of steel coils.
Our data analysis and results confirm the efficiency of the proposed system in an open-sky yards environment.
