Vote Nears for Weather Forecasting Bill That Could Boost GPS Radio Occultation Firms

Two companies angling to provide the government with cutting-edge, GPS-based weather data may get a boost this fall if a bill aiming to improve forecasting wins U.S. House approval.

The companies, Bethesda, Md.-based Planet IQ and GeoOptics, Inc., of Pasadena, California, hope to use GPS radio occultation or GPS-OR to provide the National Oceanic and Atmospheric Administration (NOAA) and the Department of Defense with weather data.

Cooperative GNSS Authentication

Equations

During the past two decades, the Global Positioning System, together with other GNSSes, has become an essential element of the global information infrastructure, with myriad applications in almost every facets of modern businesses and lifestyles, including communication, energy distribution, finance and insurance, and transportation. Ever-growing dependence on GNSS creates strong incentives to attack civil GNSS, for either an illegitimate advantage or a terrorism purpose.

IFEN and WORK Microwave Announce BeiDou-2 Support, Additional Enhancements for NavX-NCS GNSS Simulators

IFEN GmbH, in partnership with WORK Microwave, have announced the release of software update v1.9 for their NavX-NCS GNSS multi-frequency simulator product line.

A key enhancement to the NavX-NCS solution is comprehensive support of China’s BeiDou-2 navigation satellite system, according to the companies. By enabling real-time simulation of second-generation BeiDou satellite signals, NavX-NCS expands a user’s GNSS signal capability beyond GPS, Galileo, GLONASS, and satellite-based augmentation system (SBAS) constellations.

European Commission to Monitor GNSS Patents Worldwide

With a key Galileo patent dispute now set to enter its third year the European Union (EU) is moving to monitor GNSS patents around the world — a move that should give it insight into the competitiveness of European positioning, navigation, and technology (PNT) companies and a heads-up about future intellectual property (IP) issues.

State Officials Argue at AUVSI for Ban on Warrantless UAV Surveillance

Alaska Lieutenant Governor Mead Treadwell

Three key associations of state officials are recommending that states pass legislation banning the use of unmanned aerial vehicles (UAVs) for surveillance unless the person being tracked has given permission or a warrant has been issued.

The associations also recommended banning UAVs from carrying weapons and emphasizing in state laws that both UAVs and their smaller cousins, model aircraft, be operated in ways that do not “present a nuisance to people or property.”

QinetiQ, Nottingham Scientific Demonstrate Cloud-Based Galileo PRS Technology

Two British companies, QinetiQ and Nottingham Scientific Ltd (NSL), have partnered to demonstrate an Internet “cloud”-based technology that enables a wide range of high-volume, low-cost satellite navigation applications using Galileo’s Public Regulated Service (PRS).

The NSL-QinetiQ application allows a service provider to host secure navigation on one server in a back office, capture data from multiple locations and units, and subsequently verify the location of a remote user.
