u-blox Releases 4-System Antenna Module

Swiss-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.

New GNSS Signals

The 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.

Who’s Your Daddy?

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.

FY15 Budget: GPS III Procurement to Slow, Dual-Launch Funding Cut

The Air Force is slowing GPS modernization and dropping part of the funding for dual launch of satellites, said defense officials describing the President’s Fiscal Year 2015 (FY15) budget on Wednesday (March 5, 2014).

Air Force Undersecretary Eric Fanning said the Air Force would continue to “honor our investments and obligations” regarding the Global Positioning System but would “reprofile” the GPS III program so that it meets constellation sustainment demands.
