U.S. Air Force Authorizes Lockheed to Finish GPS III SVs 7 & 8

The U.S. Air Force has awarded Lockheed Martin more than $245 million in contract options to complete production of its seventh and eighth GPS Block III satellites.

The two space vehicles (SVs 07–08) received initial funding under a February 2013 long-lead material contract for the Air Force’s second set of four satellites, GPS III SV 05–08. Similar to this current award announced yesterday (April 1, 2014), the Air Force exercised an option to complete production of SVs 05–06 in December 2013.

FAA Issues Call for UAS Center of Excellence Contractor

The Federal Aviation Administration (FAA) has announced plans to establish within the next year a Center of Excellence (COE) for its Unmanned Aircraft Systems (UAS) Research, Engineering, and Development Program.

An FAA notice published last Friday (March 28, 2014) said that the agency will launch a competitive search for a team to lead the initiative as part of the FAA’s effort to integrate UAS into the National Airspace System (NAS). A draft solicitation will be available on or before April 18.

u-blox Releases 4-System Antenna Module

u-blox CAM-M8Q 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.

GPS Modernization Stalls

With the optimism of college-bound seniors touring the Ivy League, GPS managers have been weighing options to dramatically change the GPS constellation. Now, after studying the costs, considering the benefits, and assessing the funding climate, officials have made the starkly fiscal decision to stick close to home and take a few extra years to finish.

New GNSS Signals

New GNSS Signals

A. J. Van Dierendonck

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.
