By allowing the customer’s own equipment to power the RF over fiber receiver, ViaLite Communications’ new RF Connector is designed to further simplify the installation of ViaLiteHDRF over fiber links. Available on the Blue OEM for applications in the Broadcast and GPS/GNSS sectors, the connector removes the need to use a separate power supply unit (PSU).

A recent General Accountability Office (GAO) report is highly critical of the cyber security, or lack thereof, in U.S. weapons systems. One of the examples of cyber-attacks it lists is GPS spoofing.
The report, published this month, goes on to say:
“…weapon systems are dependent on external systems, such as positioning and navigation systems and command and control systems in order to carry out their missions—and their missions can be compromised by attacks on those other systems. A successful attack on one of the systems the weapon depends on can potentially limit the weapon’s effectiveness, prevent it from achieving its mission, or even cause physical damage and loss of life.”

The recently concluded Arab Institute of Navigation biennial conference in Cairo, “GNSS, the Key to Innovation,” featured a wide variety of presentations of interest to navigators and technologists alike.
Presenters ranged from representatives of the European Space Agency (ESA) and NASA, to those from a transportation company that uses GNSS-enabled tracking while transporting priceless ancient artifacts to the under-construction Grand Egyptian Museum.

While threats to American defense satellites were climbing sharply, the costs and schedules of U.S. military space programs were on the same unsustainable trajectory — prompting lawmakers last year to begin trying to reorganize Air Force’s military space programs by creating a Space Corps. A move that, so far, has failed.

LabSat by Racelogic is looking forward to sharing news on technology developments and product launches at ION GNSS+ in Miami, Sept. 26-28.
After a year’s development, the company is announcing a major update of its SatGen simulation software for use with LabSat 3 Wideband. SatGen software allows you to create a GNSS RF I&Q or IF data file that can be replayed on a LabSat which is based on a user-generated trajectory file. This allows you to simulate almost any kind of test, at a set time and date, anywhere in the world, according to the company.

The latest satellite-based augmentation system (SBAS) project update from Lockheed Martin and GMV is designed to collect data near the equatorial region and determine benefits delivered by the dual-frequency, multi-constellation SBAS.

The years-long fight over a proposal to recast satellite spectrum near the GPS frequencies for a terrestrial network is now being raised as an issue that could impact efforts to support competitiveness in satellite communications and other sectors of the growing commercial space industry.

This year’s Intelligent Transport Systems & Services (ITS) conference will be held in Denmark in September. ITS World Congress will take place from September 17-21 at the Bella Center in Copenhagen. The Congress Theme: “ITS – Quality of Life”, supports the Copenhagen belief that intelligent transport systems are an important means to enhance people’s daily lives through seamless, smart and sustainable mobility solutions.

The Air Force officially announced Friday that Lockheed Martin had been awarded a $7.2 billion contract to build 22 GPS III Follow-on (IIIF) satellites.

Once the next-generation GPS III satellites begin launching later this year, a series of updates to the current ground control system from Lockheed Martin will help the U.S. Air Force gain early command and control of the new satellites for testing and operations.

Though the Senate approved next year’s funding for the Department of Defense (DOD) just before its Labor Day break there are still hurdles to overcome before the fiscal year runs out on September 30. For the most part further delay should not greatly impact GPS efforts — as long as stopgap funding is secured to keep DOD’s doors open — but extending the deadline will likely put the GPS IIIF program on hold.

The first of the U.S. Air Force’s advanced new, higher-power, harder-to-jam GPS III satellites is making its way to the launch pad.
