Trimble will also provide complete network set up, deployment and operation during the initial start-up period.

The Trimble VRS network will provide a fixed geospatial infrastructure for surveying, engineering and geographic information system professionals that enables high accuracy real-time kinematic (RTK) Global Navigation Satellite System (GNSS) positioning, significantly increasing efficiency and productivity.

Known as HEPOS (Hellenic Positioning System), the GNSS network will consist of approximately 100 Trimble NetRS GPS Receivers and 100 Trimble Zephyr Geodetic Antennas, as well as Trimble GPSNet and RTKNet software to achieve full Trimble VRS functionality.

Covering approximately 132,000 square kilometers of mainland and islands, the HEPOS network is expected to be one of the largest GNSS networks in the world.

The network, which will be designed to cover the needs of the Greek National Cadastre far into the future, is expected to provide accurate and reliable centimeter-level surveying measurements to be taken faster and more cost-effectively throughout Greece.

The HEPOS network is expected to be fully operational by the end of 2007. The measurements will be collected in real-time and sent to the HEPOS Control Center, which will process the data and send the high accuracy positioning data to all users. All users will be able to receive data either in real-time, or through a web server for post-processing in the office.

When fully operational, the HEPOS network will be managed by Ktimatologio.
