Machine types

GPS+ is 3D machine control system using GNSS exclusively as a positioning source. The '+' refers to the fact that the system tracks GPS plus GLONASS, the Russian satellite navigation system.

This system can be regarded as the foundation for Topcon's range of 3D machine control systems. With the addition of one or several pieces of hardware, the system can be turned into an LPS-900, or a Millimeter GPS, etc.

Topcon is a pioneer in multi-constellation GNSS systems and for years was the only company to offer GLONASS tracking for machine control applications. It currently offers hardware it states is capable of utilizing the Galileo satellite navigation system currently under construction.

Through acquisitions, Topcon's 3D machine control products incorporate technology from companies such as AGTEK and Javad Positioning Systems.

Topcon's GNSS technology is developed primarily in Russia, its optical products in Japan and its 3D machine control software in Australia.

Topcon Positioning Systems, Inc. is headquartered in Livermore, California and is a wholly-owned subsidiary of Topcon Corporation, Tokyo. Topcon Corporation is a public company traded on the Tokyo Stock Exchange under the company code 7732. Toshiba Corporation is its primary shareholder with approximately 35% of the shares.
