Livermore, Calif. - November 10, 2009 - Topcon has received an order for 90 GPS receivers from the Geographical Survey Institute (GSI), an affiliate of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). This is in addition to the 360 receivers ordered in July.

Topcon will provide a total of 450 receivers for the GPS Earth Observation Network System (GEONET) operated by the GSI. It is expected the new systems, including additional 90 receivers, will be in operation by the end of March 2010.

In 1992, GSI initiated the introduction of Global Positioning System (GPS) Continuously Operating Reference Station (CORS) known as GEONET. As of November 2009, over 1,200 stations nationwide are in place providing precise positioning data to the public.

"With this addition of 90 new receivers, more than 35 percent of the GEONET stations will implement Topcon NET-G3 series receivers," said Takashi Eto, senior manager of Topcon Corporation's Global Business Planning Group and Asia & Middle East Marketing Group.

Topcon will also provide GPS observation/control software as well as a database management system exclusively designed for the GEONET.

"The NET-G3 has an ability to track currently planned L2C and L5 GPS signals. Upgrading the GEONET system with our technology and expertise will certainly benefit the users as soon as the new GPS signals will become available," Eto said.

(TPS) designs and manufactures precise positioning products and solutions for the global surveying, construction, agriculture, civil engineering, mapping and GIS, asset management and mobile control markets.
