The modernization of software complex for CCD-observation of low-Eath orbit space objects (LEO) was made. The 2074 tracking of LEO with total duration of 11.4 thousand minutes were made at TVT telescope. Database of 23.6 thousand positions was received. Orbit calculation was carried out on LEO positions database of UMOS network for 2012-2014. Obtained catalogue of ephemerides and TLE was published on the website of UMOS network. Multivariate statistic analysis of ephemerides accuracy was conducted. The experimental network of four stations for synchronized reception of pseudo noise signal of digital satellite television was created. Space coordinates X, Y, Z of geostationary telecommunication satellite (GSS) are determined from the network data. The database of GSS coordinates within 21 days was created. The RMS errors of a single measurement were 40 km, 8 km, 5 km for axes X, Y, Z, respectively.
