Position Measurement System

Yardeye utilizes several layers of advanced technologies to measure the position, heading and velocity of personnel, vehicles and cranes in the yard in real time and with a consistent accuracy.

Global Navigation Satellite System (GNSS)

Combining all available GNSSystems (Navstar GPS, Glonass, Galileo, Baidu) with Differential and RTK functionality, Yardeye delivers the position of equipment in centimeter precision and with high accuracy.

In the same “box”, a dead reckoning functionality (CAN-Bus based, Gyroscope, Accelerometer and digital Compass) is combined to provide GNSS quality indicators and allow navigation, even when GNSS Signals are not available.

Of course, this box, the SMU (State Measurement Unit) is an IoT device that also collects, processes and forwards operating data and process data to third party big data applications.

All data is received and send by W-Lan, with a Failover of 4G and RFID data channel, so via three independent channels, for maximum uptime.

Radio Frequency Identification Tag (RFID)

The term RFID is widely used in different industries, we definitely bring it to the next level. Our RFID Tags have a range of up to 1000 meters (3000 feet) and locate objects with a high accuracy of approximately one meter.

Our  RTT (Radio Transponder Tags) are the second layer to GNSS positioning but may also be used independently.

In helmet tags, the battery lasts about a year. On vehicles, they allow exact position measurement whenever GNSS is not feasible.

The sending power is ultra-low, approximate 1/10th of a cellphone, so no harm to personnel on site or communities around. Inside each helmet tag, also an accelerometer is built in, so that we detect if a helmet is being worn or just lying on the ground.

Redundant Systems

All systems have advantages and disadvantages. But by cleverly merging strengths and weaknesses to complement one another, in combination, the system becomes more powerful than its individual parts are.
Our puzzle parts are GNSS, Dead Reckoning, WLAN, 4G and RFID.

In Container Terminals We Can …

An Intermodal Yard is a complex world in which manual operation, remote control and automation meet. Several systems work together and exchange different types of data via non-homogenious and  sometimes very specific interfaces.

Besides different layers of machinery, hardware and software that work in different sectors with different tasks and at different speeds, Yardeye allows all components to be synchronized in an effective manner.

The chart below visualizes the interaction between the main control systems:

Personnel and Vehicle Position are measured by GNSS / RFID. Their position is received by the crane and through other tags in the yard (e.g. highmasts, gates, …). The Yardeye Server captures all the data, filters, fuses and cross-validates the different inputs. From there, the data is forwarded to the Terminal Operation System (TOS), Yard Controller (YC) as well as the Crane Controller (CC) / Crane Management System (CMS).

Yardeye Software – Yard Visualisation

Within milliseconds, the Yardeye System chooses and adapts crane paths. The visualisation runs both on dedicated panels (e.g. in the OPS Management Room, in the Remote Operation Room) or optionally in a Webbrowser or via an App.


Yardeye’s solution connects seamlessly into existing Terminal IT Infrastructure. We understand that we are a puzzle part in the data and material flow chain.


Our solution requires minimal or no maintenance. However, components may get damaged, lost or fail.

Yardeye offers a 24/7/365 service line for our installations around the globe. Local partners are fast responders and usually in the terminal within two hours.

Yardeye Communication

  • WiFi/Ethernet Communication
  • GNSS Communication (GPS | GLONASS | GALILEO)
  • RFID Communication (Radio Communication | 3 Frequencies)
  • PROFINET Communication

Yard Controller

Besides identification and localisation, Yardeye also provides Yard Controllers as a middleware between Crane and TOS systems. Work Orders (WO) form the TOS are sent to the Yard controller. It selects the appropriate crane for a job, plans the path to move the containers and updates it in real time based on vehicle and personnel movement in the yard.
