GPS Directorate’s Whitney: No Immediate GPS OCX Work Stoppage

GPS Directorate’s Whitney: No Immediate GPS OCX Work Stoppage

A funding shortfall will not halt work on the new GPS ground system this month, although a decision expected in the next two weeks may signal major changes in the program.

Increased personnel costs on the Global Positioning System Next Generation Operational Control System (OCX) program had eaten up the fiscal year 2016 budget and were poised to force managers to stop work on September 15. The Pentagon had requested Congress to allow $39 million to be reprogrammed to bridge the gap but lawmakers left for the summer recess without approving the change.

Defeating ‘Death by GPS’

Defeating ‘Death by GPS’

Park rangers in Death Valley National Park have begun calling it “death by GPS.” Visitors faithfully following their navigation devices turn down the wrong road or hike away from help and die before rangers can reach them.

But it really isn’t the GPS, it’s the maps in their navigation system’s database.

DHS Continues to Test GNSS Timing for Critical Infrastructure

Because GPS and other GNSS are critical to the nation’s infrastructure, the U.S. Department of Homeland Security (DHS) is testing an augmentation system and developing new requirements to protect it, a DHS official told the U.S. Department of Transportations’s Civil GPS Service Interface Committee (CGSIC) meeting this week in Portland, Oregon.

Changing the Rules

How do you win when you are really losing?

Play a different game, move the goalposts, change the rules.

For several years now, a series of would-be wireless broadband service providers have been attempting to convince the Federal Communications Commission (FCC) to repurpose radio frequency spectrum near the GPS L1 band.

Past efforts have failed because of the transmissions’ demonstrated harmful effects on GPS and other GNSS signals. Now a new contender is trying to gain FCC’s approval by changing the way that those effects are measured.

Clarion to Use Furuno’s GPS Receiver with DR/GNSS Module in Navigation System

Furuno’s GV-86 GPS receiver chip with its dead-reckoning DR/GNSS module will be integrated into Clarion’s NXR16 car navigation systems for the auto-leasing and car rental industries.

The GV-86 features a dead-reckoning-enabled GNSS receiver, which receives concurrent GPS, SBAS, and QZSS satellite signals. The dead-reckoning capability allows the unit to provide positioning while receiving multiple GNSS signals in such harsh environments as tunnels, urban canyons and underground parking, the company said.

The Particular Importance of Galileo E6C

The Particular Importance of Galileo E6C

The Galileo E6 signal is centered at 1278.75 MHz, and comprises three signals: an authorized signal (E6A, the publicly regulated service, PRS plus two civilian signals), a data component (E6B), and a pilot component (E6C). Both E6B and C are modulated using binary-phase shift keying (BPSK) code division multiple access (CDMA) memory codes, having lengths of 5,115 chips and chipping rates of 5.115 Mcps.

Geolocation Privacy

Geolocation Privacy

Reasonable Expectations of Privacy and a discussion of privacy in the United States typically begins with the Fourth Amendment of the U.S. Constitution, which provides that “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.” In U.S. v Katz, the U.S. Supreme Court found that this Fourth Amendment protection created an individual’s constitutional right to privacy.

UAS Rules Could Unleash Potential GPS Market

A new rule that took effect yesterday (August 29, 2016) eases U.S. limits on the commercial drone flights, unleashing a surging industry that depends in large measure on GPS for success.

The rule’s provisions allow operators of unmanned aircraft systems (UAS) to proceed without having to obtain waivers or flight-by-flight permissions from the Federal Aviation Administration (FAA) — a process that had caused long delays and lost business.

Lockheed Martin Advances GPS Block III Testing

More than 300 engineers, technicians, and support personnel have been working on the GPS III program, including successfully completing space vehicle (SV) 01 testing, at Lockheed Martin’s processing facility near Denver.
 
The Air Force recently exercised contract options for Lockheed Martin to complete development of eight GPS III space vehicles (GPS III SVs 01 to 08). The eight vehicles are in various stages of assembly, integration and testing, according to the prime contractor for the next-generation spacecraft.

Federal Railroad Administration Announces Status Updates to GPS-Aided Collision Avoidance System

Federal Railroad Administration Announces Status Updates to GPS-Aided Collision Avoidance System

The Federal Railroad Administration (FRA) last week released a status update that calls for railroads to roll out Positive Train Control (PTC) technologies, which incorporates GNSS technology, as soon as possible. The update also underscores the Obama administration’s calls to provide more funding to assist commuter railroads in implementing PTC.

PTC uses GNSS, but mostly GPS, to prevent train-to-train collisions, high-speed derailments, and the unauthorized movement of trains into work zones.

GPS OCX to Halt Work September 15 unless Lawmakers Act

GPS OCX to Halt Work September 15 unless Lawmakers Act

A lack of funds will force a shutdown in the development of the GPS new ground system on September 15 unless lawmakers act on a July request to redirect funds, according to the Air Force.

Although the doors likely would only be closed for a little over two weeks, a hiatus would add substantially to the total cost of the GPS Next Generation Operational Control System (OCX) and further delay completion of the already behind-schedule program, the Pentagon has told lawmakers.
