Spectracom Launches GSG-55 GPS/SBAS Constellation Simulator

Spectracom has announced its new 16-channel GPS constellation simulator, the Pendulum GSG-55.

The latest in the Pendulum line of GPS receiver test instruments, the GSG-55 is able to simulate Satellite-Based Augmentation Systems (SBAS), such as the U.S. Wide Area Augmentation System and the European Geostationary Navigation Overlay Service (EGNOS).

JAXA Selects Spirent Simulator for QZSS Receiver Testing

Spirent Communications’ Positioning Technology Division, Paignton, UK, has announced that the Japanese Aerospace Exploration Agency (JAXA) has selected Spirent’s GSS8000 Multi-GNSS Constellation Simulator to support further development of the Quazi-Zenith Satellite System (QZSS) program.

Responsible for the development of the initial QZSS user equipment, JAXA is using the GSS8000 to verify QZSS receiver performance.

GPS/ GNSS Community Feels New Telecom Interference Threat from LightSquared

In his State of the Union address on January 25, President Obama held up the Global Positioning System as a prime example of government providing “cutting-edge scientists and inventors with the support that they need” to create world-leading, job-creating innovation.

The following day, the Federal Communications Commission (FCC) International Bureau approved a conditional waiver allowing LightSquared Subsidiary LLC to build tens of thousands of terrestrial transmitters for wireless communications in frequencies on either side of the GPS L1 band.

Lockheed Martin to Test GPS III in Virtual World

GPS III contractor Lockheed Martin has integrated several virtual reality technologies in a new Collaborative Human Immersive Laboratory (CHIL) in Littleton, Colorado, which will be used to validate and test next-generation GPS and other space programs.

With CHIL, Engineers and technicians can explore satellite designs and functions, troubleshoot and fine-tune them in a virtual world before building them in physical space.

Three GPS Satellites Moved Into New Positions for More Robust, Accurate Signals

(Update June 15, 2011 Inside GNSS) Completion of Satellite Repositioing Optimizes GPS Constellation

By next June, the United States GPS constellation will attain the most optimal geometry in its nearly 33-year history. Over time, that means a more robust signal, more accuracy and more reliability in GPS-challenged environments.

The 50th Space Wing is in the middle of maneuvering six GPS satellites into more favorable positions. The two-phase operation, called "Expandable-24"  is halfway to completion.

GNSS Interoperability

In the beginning, there was only the NAVSTAR Global Positioning System (GPS): an astounding start to the world of global navigation satellite systems (GNSS).

Since the United States declared full operational capability (FOC) for GPS in 1995, two major things have occurred:

April 26, 2011 - April 29, 2011
Boulder, Colorado
June 28, 2011 - July 7, 2011
Melbourne, Australia
March 28, 2011 - April 1, 2011
