Spirent Launches Multi-Frequency Wideband GNSS Record & Playback System

Spirent GSS6425

Spirent Communications has launched its GSS6425 multi-frequency GNSS record and playback (RPS) test system, a self-contained and portable unit that allows  users to record and play back data in the field without the need for an additional PC or external power.

The GSS6425 provides customers with RF recordings on for GPS, GLONASS, Galileo, BeiDou, and QZSS (Japan’s Quasi-Zenith Satellite System) constellations, including L1, L2, and L5 frequencies representing more than 30 megahertz of bandwidth.

Europe’s GNSS Program: Interview with European Commission Vice-President Antonio Tajani

A former officer in the Italian Air Force, Antonio Tajani has been vice-president of the European Commission (EC) since May 2008. Tajani is, however, also the current European Commissioner for Industry and Entrepreneurship, which makes him top man at the European Union (EU) directorate-general that oversees the Europoean GNSS programs, particularly Galileo and the European Geostationary Navigation Overlay Service (EGNOS).

State Associations Tackle Privacy UAV Issues

State Associations Tackle Privacy UAV Issues

Three state government associations are teaming up with privacy advocates and drone proponents to craft legislation potentially critical to opening the country to the unmanned aircraft industry.

The effort, which is being spearheaded by the Aerospace States Association (ASA), could be instrumental in heading off a potentially devastating backlash against unmanned aerial systems (UAS) fueled by privacy concerns. GNSS technology is a leading candidate for UAS guidance, navigation, and control systems for many types of unmanned aircraft.

1. PESTS

State of California, USA
√ The California Agriculture department is using collective intelligence and GPS to “report a pest.” State residents can download the new CDFA smartphone app and use it to photograph and report bad bugs when they see ‘em. Those with iPhones can choose to send GPS coordinates for quick response to invasive pest emergencies.

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.

Living in an APNT World

Living in an APNT World

It’s all about the backups now. The alternatives. The gap-fillers.  

Back in the 1990s, when I first came across the U.S. Federal Radionavigation Plan (FRP), I learned that the rise of the Global Positioning System drove the biannual FRP process because of the expectation that GPS would enable the government to shut down many pieces in the hodgepodge of positioning, navigation, and timing (PNT) systems.

Calculating Time Offsets
May 23, 2013

Calculating Time Offsets

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).

MUSTER

Existing methods for improving the GNSS performance commonly attempt to enhance the signal processing and navigation estimation parts of a single receiver. Such approaches, however, leave unexplored the potential benefits inherent to the integration of data from multiple receivers.
