Distribution of visible in-orbit BeiDou satellites.

By adhering to the principles of independence, openness, compatibility, and gradualness, China has steadily pushed forward the deployment of the BeiDou Navigation Satellite System (BDS), following a planned three-step strategy. In 2000, BeiDou Navigation Satellite Demonstration System was completed. By December 2012, five geostationary orbit (GEO) satellites, five inclined geosynchronous orbit (IGSO) satellites, and four medium-Earth orbit (MEO) satellites had been launched, forming the constellation, and formally beginning service provision to the Asia-Pacific region. read more

Directions 2014: New Horizons of GLONASS

December 1, 2013By

The fundamentals of Russian government policy in satellite navigation are defined in Presidential Decree #638 of May 17, 2007, and specify that GLONASS services are provided globally and free of any user fees, and GLONASS is used as a basis of the National Positioning, Navigation and Timing System. To efficiently implement the government policy in satellite navigation, in March 2012 the Government approved the dedicated Federal Program focused on GLONASS sustainment, development, and expansion of applications. read more

A Glowing Report Doth Not a Golden Future Make

November 27, 2013By

The tech press and broad public media have both made much ado about a November market report from the European GNSS Agency (GSA). Most accounts have focused on a GSA prediction of an installed base of 7 billion GNSS-enabled devices worldwide by 2022, and nearly every account has replicated the GSA math to trumpet “almost one for every person on... read more

New GLONASS Navigation Message Proposed

September 30, 2013By

Russian scientists and engineers are at work on a new code-division multiple-access signal format to be broadcast on a new GLONASS L3 signal. Taking an approach similar to that implemented on the newly designed GPS L5 signal, this will, once implemented across the constellation by new satellite launches, facilitate interoperability with and even eventually interchangeability among other GNSS signals, including... read more

Out in Front: Geospatial on Everything

September 1, 2013By

GPS World Publisher Learns about GIS By Alan Cameron Everything has a geospatial aspect. Everything. Past, present, future.

Looking High in the Sky from Down Under

August 29, 2013By

A few months ago I wrote in the magazine’s Out in Front column about the surprising abundance of BeiDou-centric papers to be presented at the upcoming ION GNSS+ conference, to which I very much look forward — both the abundance and the conference as a whole. With GLONASS encountering stormy weather of late, and Galileo plugging steadily along but not... read more
