LITPOS - A SERVICE FOR PRECISE POSITIONING IN REAL TIME

摘要

LitPOS - the state network of permanent reference GNSS stations - is operational from July 2007. It provides data both for the real-time and post-processing applications. LitPOS stations cover the all territory of Lithuania. Total number of GNSS stations is 25 therefore the integration of some stations of neighbouring countries is foreseen. It is possible on the basis of cooperation in EUPOS project. The European Position Determination System (EUPOS) project is an initiative and cooperation of currently 15 Central and Eastern European countries (CEE) and two German states that build up a ground based European regional GNSS augmentation system with uniform standards that will cover a territory of about 10 million square kilometers. EUPOS provides high quality differential GNSS information for high precise positioning and navigation usable in a large field of applications. LitPOS is a multipurpose GNSS infrastructure for Lithuania. LitPOS combines a network of base GNSS stations with dedicated communication channels and appropriate hardware and software. Its main objective is to provide the 24/7/365 real time precise positioning service with national-wide coverage for the geodetic, cartographic, cadastral and construction applications.
