Position Detection System (PDS)

1. Feature introduction
Based on GNSS and encoder dead-reckoning technology, DONN‘s Position Detection Systems (PDS) provides precise and reliable position detection of containers and container handling equipment (RTG, RMG, SC etc.) in various terminal environments. 

2. Technical indicators
（1）Positioning accuracy of up to 10mm
（2）> 99.99% accuracy of container position detection by being combined with encoder dead-reckoning

（3）> 20 years of stable operation at HPH and DPW's terminal...

3. System features

（1）Self-adaptive to different yards and container types, compatible with the common TOS systems
（2）Identify the container position through the positioning of container handling vehicles and yard mapping, without complicated measurements.
（3）Management of all PDS data via SiteMaster, supporting remote updates and upgrades.
（4）DONN‘s PDS can communicate with various TOS, through VMT or web-based protocols.

4. System benefits

（1）Support stable operation at HPH and DPW's terminal
（2）Through GNSS RTK positioning, the direct relationship between the container location and the ground is established, so as to achieve more accurate and direct operation and positioning of the container location by the gantry
（3）Adaptive around the clock
（4）Advanced intelligent algorithms
（5）Standard interface protocol and unified entrance for multiple systems
（6）Real-time data collection and analysis process, adequate protection, standard interfaces, scalability and ease of maintenance.
