December 10, 2014By

2014 marks 40 years of my long association with the positioning, navigation and timing gold standard we call GPS. There’s no question that GPS or GNSS should remain as the bedrock for all PNT solutions. Three technologies that can build on GNSS are eLoran, inertial systems, and all signals available. read more

Directions 2015: BeiDou Belongs to China, and to the World

December 1, 2014By

By adhering to the principles of independence, openness, compatibility, and gradualness, China is steadily accelerating the construction and development of the BeiDou Navigation Satellite System. The BeiDou System already provides continuous and reliable Full Operational Services to most parts of the Asia-Pacific region. Its positioning, navigation, and timing performance keeps improving, while the deployment for a global constellation is also making progress. The BeiDou System and its products, which are compatible with other navigation satellite systems, have been gradually applied in many sectors and industries related to the national economy and to entering the mass market. read more

Last year in my “Directions” article, I emphasized the commitment made by the U.S. government to ensure GPS signals are available to all users, and I shared some of our excitement in the GPS Directorate regarding the modernized capabilities we are developing and fielding. This year I’d like to share with you progress we’ve made in the past 12 months, provide an update on the modernization initiatives, and challenge civil users and receiver companies to innovate and accelerate these modernized capabilities for users worldwide. read more

Expert Advice: Managing GPS, Take Two

December 1, 2014By

By John Lavrakas, Advanced Research Corporation What a difference eight years can make! My September 2006 GPS World article “Managing the GPS Constellation for Today’s Needs” dealt with GPS performance issues many high-precision users then faced. Demanding applications of real-time precision positioning, such as precision agriculture and machine control, did not find enough satellites in view to support their needs. I... read more

Regional mandates already exist for Glonass in Russia and Beidou... read more
