ComNav Technology T100 Certified as Class 1 GNSS Surveying Instrument by Geospatial Information Authority of Japan

GEOSURF CORPORATION (Headquarters: Ota-ku, Tokyo; President: Masayuki Uchiyama) is pleased to announce that the ComNav Technology Ltd.-manufactured GNSS receiver 'T100', which it sells, has been registered as a 'Class 1 GNSS Surveying Instrument' under the instrument registration system of the Geospatial Information Authority of Japan (GSI), effective July 15, 2026. The registration number is No. 260.

Achieving Class 1 Certification Despite Being an Entry-Level Model

The T100 is a lightweight, compact GNSS receiver designed for affordability and ease of adoption. While high-performance surveying instruments are typically large and expensive, the T100 has achieved certification as a Class 1 GNSS Surveying Instrument by meeting the GSI's stringent performance standards, despite prioritizing portability and cost-effectiveness. This certification enables users to confidently deploy the T100 in public surveying projects and other applications requiring high positioning accuracy.

Bringing High-Precision GNSS to More Work Sites

The surveying industry faces challenges such as labor shortages and the need for improved operational efficiency, while the high cost of advanced equipment remains a barrier. The T100 was developed under the concept of 'delivering essential performance at a more accessible price.' With this Class 1 certification, the T100 will make high-precision GNSS surveying more accessible not only to surveying companies but also to construction firms, infrastructure maintenance providers, and sectors such as forestry and agriculture.
