iPNT standardization STANDARD

iPNT has compatibility with the GNSS signal standard.
This allows for using the same basic hardware design as standard GNSS receivers while adapting the firmware to receive iPNT messages.

Increasing reliability of the overall iPNT system hinges on adding more compatibility between manufacturers’ iPNT devices and standardizing the format of messages and the interfaces used.

Standardization of iPNT is being performed by The Association of Indoor Messaging Service (TAIMS), which is creating and managing specification documents.

The Association of Indoor Messaging Service (TAIMS)

This organization was founded on April 10, 2018 in order to contribute to the promotion and widespread use of high-accuracy indoor positioning and time synchronization infrastructures.


In June of 2011, we launched the IMES Consortium, the predecessor to TAIMS. Over seven years, we participated in government pilots for high-accuracy positioning solutions, created systems and guidelines for the provision of indoor positioning data in medical facilities and automotive plants, and served as a hub for the exchange of new information and ideas. IMES demonstrated the viability of “location authentication” solutions. Now, we have launched an association in order to jumpstart this new specification, which features time synchronization data transmission capabilities.

Specific business areas

Creation and maintenance of iPNT (solutions for accurate indoor positioning data, time synchronization, and transmission of disaster safety information) specifications documents
Certification of iPNT transmitters and issuance of certificates
Registration of iPNT transmitters and maintenance of registration data
Creation and maintenance of guidelines concerning use of iPNT
Public relations towards the proliferation and development of iPNT
Other matters for the achievement of the corporation’s goals

Current activities

We are currently deliberating with government offices as we plan to handle a national project for the use of advanced time data.
In addition to providing a basic national infrastructure for time synchronization, we are also exploring potential companies and institutions with whom we can work in terms of providing private sector applications (for use in smart factories, financial trading, next-generation telecommunications (5G), IoT, smart grids, next-generation broadcasting, geo-fences, smart cities, indoor disaster information systems, and E911).
