Global Navigation Satellite Systems Engineering, Policy, and Design
The 2015 World Congress of the International Association of Institutes of Navigation will take place at a new venue, the Corinthia Hotel, close to the well-preserved historical center of Prague, Czech Republic, on October 20 – 23, 2015. This will be the 15th meeting of all of the member organzations, who will discuss the science and practice of navigation and related technologies.

Jim Williams, FAA UAS Integration Office. AUVSI photoCompanies hungry to offer commercial services in the United States with unmanned aircraft finally have something to chew on.
The Federal Aviation Administration (FAA) has laid out a process whereby a carefully selected set of unmanned aerial systems (UAS) may be granted an exemption to do for-pay flights before the first broad rules for U.S. flying unmanned aircraft are finalized.

u-blox CAM-M8Q moduleSwiss-based u‑blox has introduced the CAM-M8Q GPS/GLONASS/BeiDou/QZSS antenna module. The module integrates a u-blox M8 satellite receiver IC plus SAW filter, LNA, TCXO, RTC, passives, and a pre-tuned GNSS chip antenna in a 9.6 x 14.0 x 1.95 mm package.
According to the company, the surface-mount antenna module combines low power consumption with high-sensitivity, high jamming immunity, and concurrent GNSS operation (GPS/GLONASS, GPS/BeiDou, or GLONASS/BeiDou), offering a drop-in solution product designers and system integrators.

A. J. Van DierendonckThe world’s GNSS systems are entering a phase of transformation — modernization of existing systems (the U.S. Global Positioning System and Russia’s GLONASS) and development of new systems (China’s BeiDou and Europe’s Galileo) that benefit from the lessons learned from the original GNSSs.
Notable among the modernization initiatives is an interest in implementing new satellite signal designs. These include the GPS L5, L2C, and L1C signals as well as those signals designed for Galileo and BeiDou. GLONASS designers are also working on modernized signals.

In this article, we will take a look at the various GNSS signals from the perspective of their cost-benefit tradeoffs. First, we’ll look at the evolution of consumer GPS architecture to date — where acquisition speed and sensitivity have been the main drivers of receiver architecture. That architecture has evolved rapidly to take full advantage of the characteristics of the GPS C/A code.
