IFEN and WORK Microwave Announce More Upgrades for NavX-NCS Simulators

IFEN GmbH and WORK Microwave have announced a new round of enhancements to the NavX-NCS line of GNSS multi-frequency simulators.

Increased usability and control is achieved through the new NCS Control Center software release V1.7, according to the Germany-based companies. The GNSS simulators now feature motion models that simulate the physical behavior of various types of vehicles or vessels, including airplanes, trains, cars, trucks, and ships.

Galileo GNSS Through Children’s Eyes

Galileo by Irina of Romania

[Updated March 27] We see lots of graphs, schemata, renderings and photographic images of the GNSS satellites and constellations. Perhaps it’s time to rest the eyes with imaginative images of space and satellites through the eyes of children.

Over a number of years, up to 30 of Europe’s Galileo navigation satellites are expected to reach orbit and each of them will be named after a child from one of the 27 European Union countries.

The Air Force is poised to forego putting nuclear detonation detection sensors on the Space-Based Infrared System (SBIRS) satellites, a decision that could complicate efforts to maintain the GPS system by hampering plans to launch multiple, lighter GPS satellites on a single rocket.

NAV12 and the Royal Institute of Navigation Request Your Papers, Please

The University Park Hotel under construction next to the East Midlands Conference Centre

The British Royal Institute of Navigation has given prospective authors a May 4 deadline for abstracts for its annual conference, NAV12. The theme this year is "GNSS and Beyond."

Authors have a broad choice of navigation and technology topics from GNSS, eLoran and integrated systems technology to satellite navigation vulnerabilities to jamming and space weather to low-cost consumer apps design.

Coarse Time Positioning
March 15, 2012

Coarse Time Positioning

Q: What is Coarse Time Positioning and how does it work?  

A: Coarse time positioning is used to provide a position fix using inaccurate time information when tracking sufficiently weak GNSS signals such that the navigation message cannot be extracted reliably. This article presents the key aspects of coarse positioning, including some of its challenges. To start, however, we begin by looking at the role of time within a GNSS receiver.

The GPS Dot and its Discontents

In-home construction of the first civilian-owned civil GPS spoofer.

Over the last few years, several of us in the GNSS community have done our best to convince our colleagues, policymakers, and the general public that unsavory characters with GNSS jammers or spoofers are a genuine threat to GNSS and an orderly society.

"But who would want to use a jammer or spoofer?” people ask.

My response? Hackers, because they can. Thieves planning to snatch expensive cargo. A moonlighting employee in the company car. Worse yet, state actors or terrorists targeting our national infrastructure.

Air Force Space Command Head Supports GPS Spectrum Needs at House Subcommittee Hearing

U.S. Air Force Gen. William Shelton , commander of the Air Force Space Command (AFSPC), told a recent House Armed Services subcommittee hearing that the LightSquared controversy at the Federal Communications Commission (FCC) underlined the need to protect GPS spectrum “Whether it is by policy within the FCC or whether that is by legislation. . . “

Shelton’s comments came during March 8 testimony on the Fiscal Year 2013 National Defense Authorization Budget Request for National Security Space Activities before the Strategic Forces Subcommittee.
