Various designs of inertial/GNSS integrated navigation systems exist, with different architectures depending on the quality of sensors, the mission, the dynamics of the vehicle, and the non-linearity of the dynamics model, measurement model, or both.

Navipedia — The GNSS Wiki

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe's Galileo Operations and Evolution.

In the last 30 years, satellite navigation applications have grown in number and kind, entire new systems have emerged, and existing systems have modernized.

LTE, Positioning, and the Implications for GNSS Over-the-Air Testing

Long Term Evolution (LTE) technology in mobile communications, often called 4G, is making its way into a host of consumer devices. It started with data-only modules for Internet connectivity but quickly made its mark on smartphones, automotive communication, and embedded modules that provide fast and reliable wireless data connectivity to the machine-to-machine (M2M) market.

UK Revokes Key GNSS Patent That Sparked Dispute over Cooperation, Interoperability

Legal filings suggest the U.S and the United Kingdom may be well on their way to working through a heated dispute over patents that, if left unresolved, could scuttle efforts to make GPS and Galileo interoperable.

European Space Solutions: A Different Kind of Galileo Public-Private Initiative

A combined conference and trade fair, European Space Solutions — scheduled for December 3–5 in Central Hall, Westminster Storey’s Gate, London, England — will bring businesses and the public sectors together with users and developers to explore how space technologies and applications, including satellite navigation, can make a difference in the lives and livelihoods of people across Europe.

Indoor Navigation Smartphone App wins 2012 Galileo Masters Prize

Finding your way will be even easier with a new smartphone app from two Portuguese research institutes that augments GNSS with ultra-low magnetic field communication (ULF-MC) for reliable navigation in office buildings, airports, underground parking garages and other indoor locations.

China Plans New BeiDou Launch, Agrees to ITU Coordination in Galileo Signal Dispute

China’s Xinhua state news agency has reported that a 16th satellite will be added to the nation’s BeiDou-2 (Compass) GNSS system by the end of this month.
