1 Scope

This part of the OPC UA specification extends the overall OPC UA series by defining the information model for global positioning and the integration of local and global coordinate systems. This document describes three models that build upon one another as follows:

  • Global Positioning Model: Defines the core elements - GlobalPositionType, GlobalLocationType, and ZoneType. These elements capture key parameters such as latitude, longitude, elevation, and accuracy in a global context.
  • Coordinate Transformation Model: Adds the means to convert local coordinate systems into global ones (e.g., GPS and EPSG-based coordinates) and vice-versa. This model enables a precise and seamless mapping between local and global spatial data.
  • Integration Model: Provides the rules and additional elements needed for OPC UA systems to manage and exchange position information. It ensures that data from both local and global coordinate systems can be interpreted consistently.

OPC Foundation

OPC is the interoperability standard for the secure and reliable exchange of data and information in the industrial automation space and in other industries. It is platform independent and ensures the seamless flow of information among devices from multiple vendors. The OPC Foundation is responsible for the development and maintenance of this standard.

OPC UA is a platform independent service-oriented architecture that integrates all the functionality of the individual OPC Classic specifications into one extensible framework. This multi-layered approach accomplishes the original design specification goals of:

  • Platform independence: from an embedded microcontroller to cloud-based infrastructure
  • Secure: encryption, authentication, authorisation, and auditing
  • Extensible: ability to add new features including transports without affecting existing applications
  • Comprehensive information modelling capabilities: for defining any model from simple to complex

PROFINET Standardization Group (PNO)

The PROFIBUS and PROFINET user organization (PNO: Profibus Nutzerorganisation e.V.) was founded in 1989 and is the largest automation community in the world and responsible for PROFIBUS and PROFINET, the two most important enabling technologies in automation today. The PNO is member of PROFIBUS and PROFINET International (PI).

The common interest of the PNO global network of vendors, developers, system integrators and end users covering all industries lies in promoting, supporting, and using PROFINET. Regionally and globally about 1,400 member companies are working closely together to the best automation possible. No other fieldbus organization in the world has the same kind of global influence and reach.

AIM

AIM (including AIM Global) is the leading industry association and worldwide authority on automatic identification & data capture technologies (AIDC/AutoID), which comprise barcode, OCR, 2D code, RFID, NFC, RTLS, sensors and mobile computing. It is serving members around the globe as a trusted resource for more than 40 years. AIM actively supports the development of standards through its own Technical Symbology Committee (TSC), Global Standards Advisory Groups, the US and European RFID Experts Groups (REG / EREG) and the IoT Experts Group. Furthermore, AIM experts take a leading role at working groups at standardisation organisations like ISO, ANSI, CEN, CENELEC, ETSI and DIN. AIM Germany (AIM-D e.V., Lampertheim, Germany: www.AIM-D.de) is the regional chapter for central Europe (Germany, Austria, Switzerland). AIM members include technology providers, systems integrators, consulting firms, research institutes and other associations. AIM's general goal is to facilitate the market dissemination of AIDC technologies on a reliable basis for the benefit of solution providers and users.
