GLONASS Constellation Grows to 17 as Latest Satellites Come On-line

Russian Proton Launcher Carrying Latest GLONASS Satellites at Baikonur Space Center

The latest trio of modernized GLONASS satellites (GLONASS-M) have begun transmitting healthy navigation messages, bringing the total of operational satellites to 17 — a milestone for the Russian GNSS constellation.

The third GLONASS-M space vehicle (SV) — SVN 726 launched September 25 began transmitting a healthy navigation message on November 13, giving the rebuilt GLONASS constellation the highest number in more than a decade. GLONASS SVN 110 (724) began transmitting on October 26, and SVN 111 (725), on November 5, according to the Russian Space Agency (Roscosmos) GLONASS Information-Analytical Center.

The EU’s Galileo Satellite Navigation System: ‘Step-by-Step’ Progress

One is tempted to paraphrase Julius Caesar, “Galileo est omnis divisa in partes tres,” because, as with any global navigation satellite system, Galileo as a whole is divided into three main parts: the political, the infrastructural, and the user application marketplace.

SpectraTime to Supply Atomic Clocks to IRNSS

SpectraTime has announced its receipt of a contract valued at approximately €4 million to supply rubidium space clocks for the Indian Regional Navigational Satellite System (IRNSS), a GNSS system that is under development by the Indian Space Research Organization (ISRO).

The IRNSS will consist of seven satellites, three in geostationary orbit and the other four in geosynchronous orbit. First launch of an IRNSS is currently expected in 2009. The system will transmit BOC(5,2) and BPSK signals at the L5 frequency (1176.45 MHz) and also in S-band.
