This annual conference on the Croatian Adriatic aims at GNSS experts and covers the risks and vulnerabilities of the global navigation satellite systems and efforts to improve accuracy and reliability.
It will take place at Baska on the resort island of Krk in Croatia from May 21 to May 24, 2012.
A discontinued model of GPS Jammer offered through UK website.Increasing incidences of interference to GNSS signals has led to a crackdown on Internet-based companies offering devices to jam cell phone, Wi-Fi, and GPS signals.
In October, the Federal Communications Commission (FCC) Enforcement Bureau issued 21 enforcement actions against online retailers in 12 states for illegally marketing more than 215 different models of wireless communications jammers, including nearly 80 types of devices that could jam GPS signals.

MVS-California, the 2011 USA Challenge winner, grabs the top prize at European Satellite Navigation Competition (pictured: ESNC organizers Thorsten Rudolph and Ulrike Daniels with Bavarian state minister Martin Zeil and winners Tom Zamojdo and Juliana Carnes Clegg. (The two women on the right are unidentified.)
MVS-California, LLC, winner of the USA Challenge, took the top global prize in this year’s European Satellite Navigation Competition (ESNC) with the company’s True3D Head Up Display & Navigation System.
The company’s innovation is an augmented reality navigational display engine designed to provide non-distracting, translucent location guidance to untrained operators of any type of vehicle.
[Updated October 3] All five of the world’s major satellite navigation systems are poised to offer new capability — if the money comes through — program representatives told attendees at the recent Institute of Navigation’s GNSS 2011 conference in Portland.
The satellite navigation systems in China, Japan, and the United States have each recently had new satellites added, while those in Russia and Europe are poised for new launches. Budgets are in flux for most systems, however, so it remains to be seen how the systems will advance over the next year.

Equation 1Q: How does measurement differencing affect my computed position?
A: The short answer is, “That depends.”
Standalone, or undifferenced, measurements obviously produce the poorest positioning performance. However, how we proceed from this most basic data processing approach may affect the computed solution. In this article, we look at the details of why this occurs.
