Inside GNSS • May/June 2013
The fourth China Satellite Navigation Conference (CSNC 2013) wound up its three-day run on May 17 in Wuhan — by all measures a clear success for an event that has become the nation’s leading international GNSS forum.
A key take-away from the event: China is rapidly preparing to bring BeiDou products and technology into the international marketplace is encouraging its industry to build an internationally applicable knowledge base in standards, patent law, and intellectual property rights (IPR).
Inside GNSS • May/June 2013
Since announcing plans in late 2006 to build its own GNSS system — BeiDou-2 (BDS), China proceeded quickly to establish a fully operational regional system late last year with a clear plan to complete a global system by 2020.
Beginning with its first launch in April 2007, BDS has put 16 satellites in orbit, some in dual launches, with 14 BeiDou space vehicles currently transmitting healthy signals: 5 in geostationary orbits (GEO), 5 in inclined geosynchronous orbits (IGSO), and 4 middle Earth orbit (MEO) spacecraft.

SIDEBAR: Di Qiu's Compass Points
Landing all-weather aircraft safely in storms. Protecting sensitive data not only through encryption but based on the location at which it is being accessed. Ensuring that accurate and timely information reaches first responders responding to emergencies.
Although still in the early part of her career, Di Qiu has already made significant contributions to these crucial applications of navigation technology.

Q: How do you deal with timing differences between GNSSs?
A: All GNSSs inherently depend on precise timekeeping to measure the satellite/receiver time of flight of signal propagation with sufficient accuracy to compute ranges/distances for multilateration calculations. Each GNSS ground segment therefore dedicates considerable effort to maintaining a highly stable atomic time scale as well as the corresponding offset to global standards such as UTC (Coordinated Universal Time).
Events • May 22, 2013
Inside GNSS will host an applications-oriented web seminar on GNSS and inertial integrated systems on Tuesday, June 18.
The free event is sponsored by KVH Industries.
Webinar presenters are Xavier Orr, an R&D engineer of 3D navigation technologies at Advanced Navigation in Australia and Andrey Soloviev, principal at Qunav LLC and a research engineer who focuses on multi-sensor integration for navigation applications.
GNSS Solutions editor and University of Calgary professor Mark Petovello moderates.

The fourth China Satellite Navigation Conference (CSNC 2013) wound up its three-day run on Friday (May 17, 2013) in Wuhan — by most measures a clear success for an event that has become the nation’s leading GNSS forum.
Well more than 2,000 attendees had their choice of 627 technical papers spread across a broad array of topics in 12 session tracks under the conference theme: BeiDou Application — Opportunities and Challenges.”
