Springer Handbook of Global Navigation Satellite Systems

The Springer Handbook of Global Navigation Satellite Systems is now available.

Described as “A state-of-the-art description of GNSS as a key technology for science and society at large,” the 1,327-page tome is edited by Peter J.G. Teunissen and Oliver Montenbruck.

Teunissen is a professor of Geodesy and Satellite Navigation at Curtin University, Australia, and Delft University of Technology (TU Delft), the Netherlands.

Montenbruck is head of the GNSS Technology and Navigation Group at the DLR’s German Space Operations Center, Oberpfaffenhofen, and chair of the Multi-GNSS Working Group of the International GNSS Service. Read more…

Consortium records scintillation on Galileo signals in Antarctica

Septentrio PolaRx5

Septentrio PolaRx5

At the end of 2016, the DemoGRAPE consortium observed, for the first time ever, ionospheric scintillations on Galileo signals in Antarctica, using Septentrio’s PolaRx5S GNSS reference receiver.

DemoGRAPE investigates improvement of high-precision satellite positioning with a view to developing scientific and technological applications in Antarctica. At higher latitudes, GNSS signal degradation due to ionospheric activity is more pronounced.

The more precise phase-based positioning modes are particularly vulnerable to ionosphere disturbance such as scintillations. Elevated ionospheric activity can cause a loss of precise-positioning mode or, in more extreme cases, a total loss of signal lock. Read more…
