China Places 23rd BeiDou Satellite into Orbit

China launched another BeiDou satellite on Sunday (June 12, 2016, local time) to support its GNSS constellation.

The satellite, launched from the Xichang Satellite Launch Center in southwest China's Sichuan Province, was taken into orbit by a Long March-3C carrier rocket. It is the 23rd satellite in the BeiDou Navigation Satellite System (BDS), a new-generation BeiDou-2 spacecraaft, and the seventh geostationary Earth orbit satellite (GEO) in the BeiDou constellation.

Inter-Signal Correction Sensitivity Analysis

Modernized GPS satellites give civil users the ability to achieve dual L1/L2 PY accuracy using dual L1CA/L2C ionosphere-free measurements and, with IIF satellites, dual L1/L5 signals. Because broadcast GPS ephemeris data is based on an ionosphere-free pseudorange calculated from dual L1PY/L2PY measurements and the civil signals are not all perfectly aligned to it, new broadcast parameters and a new modernized dual-frequency algorithm are needed in order to align new signals with the dual L1/L2 PY signal.

GNSS Evolutions for Maritime

Trends for marine accidents show rising numbers and costs that are mainly associated with collisions and groundings. Research indicates that about 60 percent of these accidents are caused by human error. The majority of them could have been avoided by providing suitable input to the navigation decision-making process, according to a 2008 report by the International Maritime Organization (IMO) Marine Safety Committee. (See IMO 2008 in Additional Resources section near the end of this article.).
