Countering Ionospheric Disturbances Affecting GNSS in Brazil By Marcio Aquino After 27 months of intense research, the CALIBRA project ended successfully in February 2015, with the project team devising solutions to tackle the effects of perturbations typical of the Brazilian ionosphere on high-accuracy GNSS positioning. CALIBRA was funded by the European Union and the European GNSS Agency. Kicked off in 2012, CALIBRA first confirmed the vulnerability of... read more

Sentry in red, sensor locations in green.

By Jeffrey Coffed and Joseph Rolli, Harris The first and best step to combat the growing worldwide problem of GPS jamming is to pursue technologies that can detect and locate the jammers. Signal Sentry 1000 uses arrayed sensors to do just that: look out for jamming and track down its source once sensed. An array of sensors can be deployed... read more

QinetiQ Announces Robust GNSS Receiver for Galileo PRS

July 14, 2015By
The QinetiQ PRS receiver.

QinetiQ today announced a major breakthrough in developing a robust navigation receiver that will use the Galileo, Europe’s satellite navigation system — in particular, the secured Public Regulated Service (PRS). QinetiQ’s new high-performance, next-generation GNSS receiver is multi‑constellation and multi‑frequency, and is designed to process encrypted signals from the Galileo PRS service as well as open services such as GPS. Qinetiq introduced the... read more

Street Smart: 3D City Mapping and Modeling for Positioning with Multi-GNSS

July 1, 2015By
Figure 1. Example of the GNSS signal propagation using ray-tracing and a 3D building map.

A particle-filter-based positioning method using a 3D map to rectify the errors created by multipath and non-line-of-sight signals on the positioning result delivered by a low-cost single-frequency GPS receiver takes a multi-GNSS approach, using the combined signals of GPS, GLONASS and QZSS. The method outperforms conventional positioning in availability and positioning accuracy. It will likely be fused with other sensors in a future pedestrian navigation application. read more
