IFEN Adds BeiDou-Compass Capability to Its Multi-GNSS Simulator

IFEN GmbH has announced that the company has enhanced its NavX-NCS multi-GNSS RF constellation simulator product line to support China’s Compass/BeiDou-2 GNSS system.

Together with its WORK Microwave partner, IFEN has added the BeiDou B1 civil signal to its current suite of GNSS signal generation capabilities, which include GPS, GLONASS, Galileo, QZSS, and SBAS. The companies used the modulation scheme and signal specifications outlined in accordance with the latest version of the Compass/BeiDou Signal in Space Interface Control Document.

Cybersecurity Bills Could Reshape GPS Anti-Interference Efforts

Legislation moving through Congress could reshape efforts to counter GPS interference as the government steps up its efforts to fight cybercrime and protect critical systems like the power grid and communications networks.

Though cybersecurity generally focuses on protecting information systems the broad definitions in some legislation now on the Hill appear to encompass GPS support systems, some user communities, and even the constellation itself.

China Succeeds with Dual BeiDou-2 Compass Satellite Launch

China Succeeds with Dual BeiDou-2 Compass Satellite Launch

Two Beidou-2 MEO satellites go up on a Long March rocket

China successfully launched two Compass satellites into space at 4:50 a.m. Beijing Time on Monday, April 30 (20:50 UTC, April 29).

Designated Compass M3 and M4, these are the 12th and 13th of its second-generation Beidou-2 spacecraft to reach orbit and the second and third middle-Earth-orbiting (MEO) spacecraft launched by China’s GNSS program.

British Military Claims Patent on GPS, Galileo Civil Signal Structure

British Military Claims Patent on GPS, Galileo Civil Signal Structure

Variations on the common GPS/Galileo MBOC signal

The British military establishment is seeking royalties from GPS receiver manufacturers, asserting it holds a patent on the technology at the heart of the new GPS and Galileo civil signals.

Should U.S. manufacturers have to pay royalties, American GPS users, who have already paid for the GPS constellation and made it available to the world free of charge, could find themselves spending more to use its location capabilities. Sources said the development could undermine relations between the U.S. and the European Union (EU), which have cooperated for years to develop a common signal at the L1/E1 frequency centered at 1575.42 MHz.

NASA Backs Test of Real-time GPS Earthquake Mitigation Network

Location of real-time GPS monitoring stations in the western United States that make up part of the Real-Time Earthquake Analysis for Disaster Mitigation Network. The networks stations are overlain on a U.S. Geological Survey seismic hazard map showing areas forecast to have a 10-percent probability of exceeding a certain level of ground shaking within the next 50 years. (Areas in shades of red have the strongest shaking, while areas in green shades have the weakest shaking.) Image credit: USGS/UC Berkeley/Scripps Institution of Oceanography

Evolution of real-time GNSS reference networks and data processing has evolved to the point that NASA-backed researchers believe they can soon implement large-scale demonstration tests to provide earthquake and tsunami alerts to the general public and emergency responders.
