Global Navigation Satellite Systems Engineering, Policy, and Design
GPS signal side lobes. When the European Space Agency launched its Galileo In-Orbit Validation Element-A (GIOVE-A) satellite in 2005, its main mission was to transmit Galileo test signals that secured the system’s frequencies, evaluate hardware under space environmental conditions, and so forth.

The International GNSS Service (IGS), a worldwide federation of agencies involved in high-precision GNSS) applications, has announced the launch of its Real-Time Service (RTS).
The RTS is a global scale GNSS orbit and clock correction service that enables real-time precise point positioning (PPP) and related applications requiring access to IGS low latency products. The RTS is offered in beta as a GPS-only service for the development and testing of applications.

NH Santo Stefano HotelThe 2013 International Conference on Localization and GNSS will take place from June 25 to 27 at the NH Santo Stefano hotel in downtown Torino, Italy.
ICL-GNSS 2013 will address the latest research on satellite-based and complementary positioning techniques for use outdoors and indoors, and on different platforms such as stand-alone navigators, PDAs and mobile devices.
The emphasis is on GNSS receiver design, related signal processing methods and leading-edge technologies.
By Inside GNSS“The GNSS Quartet” (January-February 2013, Inside GNSS, aptly named and coauthored by Glen Gibbons, Dee Ann Divis, and Peter Gutierrez) is reminiscent of Dr. Brad Parkinson’s observation about “interchangeability” at his ION GNSS 2011 plenary session. With interoperability taken to its logical level of completion, a position solution should be readily obtainable from four satellites, each belonging to a different constellation.

1. LATE LAUNCHES
Cape Canaveral and Plesetsk
√ [updated April 1] After three delays, a single GLONASS-M satellite will go up from Plesetsk space center on April 26. The United States will send up SVN66, the fourth GPSIIF satellite— on an Atlas V launcher for the first time—during the early evening of May 15. It had been delayed from March.
TABLE 1: Deployment Status Note: Two types of clocks on board: PHM = Passive Hydrogen Maser, RAFS = Rubidium Atomic Frequency StandardEurope’s new age of satellite navigation has passed a historic milestone — the very first determina-tion of a ground location using the four Galileo satellites currently in orbit together with their ground facilities.
This fundamental step confirms the Galileo system works as planned.
