Don Jewell visits the Exelis table at the GPS World Leadership Dinner.

Many may consider it a distinction without a difference, but quality matters, whether it concerns a life-changing decision or something as simple as which conference to attend. When resources are scarce, making the right decision, or sometimes just making any decision, matters — for many in our government this paradigm should reign supreme. Over the past 24 months, it seems... read more

Constellation snapshot for a specific date/time: GPS week 1749 (725) and GPS seconds 86400 = July 15, 2013, at midnight GPS Time.

Orbital Planes, Nightmares, Pioneers Good morning, Dr. Langley, I have a seven-year-old drawing of GPS satellites in their orbital planes that I found (can’t recall where) some years ago, either on a website or from a colleague who attended some GPS forum. Would you know of a site where I can find current information on GPS satellite locations, which ones... read more

Ground Control Readied for GPS III

September 30, 2013By

Raytheon Company reached several milestones recently in its development of the GPS Next -Generation Operational Control System (GPS OCX).  Lockheed Martin’s GPS III Non-flight Satellite Testbed (GNST) — a full-sized, functional satellite prototype currently residing at Cape Canaveral Air Force Station — successfully established remote connectivity and communicated with OCX during pre-flight tests. GNST proved that it could connect with... read more

SignalSentry1000

Signal Sentry 1000, an Exelis product that detects and locates GPS interference sources in 3-D by using longitude, latitude and altitude has demonstrated successful results during a planned field testing event held last week at the Vidsel Test Range in Sweden. Taking advantage of the range’s remote location, Exelis was able to conduct tests of its Signal Sentry 1000 product... read more

Rockwell Collins Awarded Contract to Develop Secure Software-Defined Radio GNSS Receiver Capability

September 18, 2013By

Rockwell Collins has received a 2 million contract from the Air Force Research Laboratory (AFRL) to develop and demonstrate a secure software-defined radio (SDR) GNSS receiver capability. GNSS typically refers to equipment that can receive signals from multiple navigation satellite systems including GPS, GLONASS, Galileo, and the Chinese BeiDou system. By utilizing multiple available satellite signals, a GNSS receiver can... read more

Ekinox-Land-Solution-O

At ION GNSS+ this week, SBG Systems announced the release of the Ekinox Land Solution, an all-in-one solution combining the cost-effective inertial navigation system with an odometer, and a GNSS RTK reference station for smooth positioning in land applications. GPS positioning in urban canyons, forests, or tunnels has always been challenging. By taking the best of these complementary technologies, Ekinox... read more

AFIT, Locata Partner on GPS Technology Development

September 16, 2013By
AFIT-Locata Kick-off Meeting. This is the first picture ever released by Locata which shows their radically new switching antenna, a design that AFIT will now modify for use with GPS receivers. Pictured (L-R): Dr. Steve Hewitson & Ian Sainsbery (Locata engineers); Jason Barhorst (AFIT); David Small (Locata technology inventor), Nunzio Gambale (Locata CEO), Dr. John Raquet (Director, Advanced Navigation Technology Center, AFIT), Dr. Peter Collins (AFIT), Dr. Trevor Hobbs (Locata Director of R&D).

The Air Force Institute of Technology (AFIT) and Locata Corporation have signed a Co-operative Research & Development Agreement (CRADA) to build and demonstrate new Locata multipath mitigation technology for use in GPS receivers. This cooperation is expected to leverage many years of proprietary Locata ground-based technology development to bring completely new capabilities to satellite-based GPS receivers, AFIT said. The Air... read more
