2012 Delta IV Launch Investigation Results Delay Fifth GPS Block IIF

Planned launch of the fifth GPS Block II-F satellite on a Delta IV rocket has been delayed twice and now has no firm date for a new attempt.

Officials with the United Launch Alliance (ULA) — a 50-50 joint venture owned by Lockheed Martin and Boeing — attributed the delay to recent results of the second phase of an investigation into an anomaly that affected the second stage of a Delta IV GPS launch in October 2012.

Harm Claim Thresholds May Be Coming for GNSS

A group of top frequency experts recommended last week that the Federal Communications Commission (FCC) conduct a pilot test of the concept of “harm claim thresholds” (HCTs), an approach that requires receiver manufacturers to build devices capable of withstanding a predetermined level of interference from users in adjacent frequencies.

Air Force May Delay Phasing Out L2 Semi-Codeless Signal

Air Force May Delay Phasing Out L2 Semi-Codeless Signal

The Air Force may hold off on phasing out codeless and semi-codeless access to the GPS L2 signal in light of delays to GPS modernization, experts told attendees at the recent Civil GPS Service Interface Committee (CGSIC) meeting. The issue will likely be discussed as part of the formulation of the 2014 Federal Radionavigation Plan (FRP).

“Semi-codeless retirement in 2020 is being evaluated,” said Col. Colonel Harold Martin, deputy director of the National Coordination Office for Space-Based Positioning, Navigation, and Timing (PNT).

Obama Administration Directive Lifted Limits on NSA Domestic Spying, including GPS Location Data

In 2008, the campaign of President Barack Obama pioneered the use of social media to power his way to the White House. In 2010, the president unleashed the National Security Agency (NSA) to collect and analyze details — including geolocation derived from GPS and other positioning technologies — of billions of American citizens’ telephone calls, e-mails, and social media such as Facebook.

GAO Report: More Research Needed to Determine GPS Program Changes

GAO Report: More Research Needed to Determine GPS Program Changes

Air Force officials should get more cost and user information and determine how many GPS satellites they will support before making decisions about revamping the navigation system, the Government Accountability Office (GAO) has told Congress.

Although an Air Force report about program options was “a good starting point, more information on key cost drivers and cost estimates, and broader input from stakeholders would help guide future investment decisions,” the GAO wrote in an assessment of the defense agency’s analysis.
