    Hexagon’s Acquisition of Veripos: Why Did This Go Down?

    From a weather perspective, Aberdeen, Scotland, may not be the most inviting location in the world in which to live. Nevertheless, Aberdeen is the leading European oil & gas business hub and is one of eight “super cities” spearheading the UK’s economy. But it’s waaaaay up north of the border with England on the east coast of Scotland — winter conditions can be difficult, even inhospitable at times. But if you want to transmit differential corrections out to shipping and...

    GLONASS Loses Control Again

    The GLONASS constellation has suffered a major problem for the second time this month. On Monday, April 14, eight GLONASS satellites were simultaneously set unhealthy for about half an hour, meaning that most GLONASS or multi-constellation receivers would have ignored those satellites in positioning computations. In addition, one other satellite in the fleet was out of commission undergoing maintenance. This might have left too few healthy satellites to compute GLONASS-only receiver positions in some locations....

  • Protect, Toughen, Augment: Words to the Wise from GPS Founder

    “What can we do to reduce the vulnerability [of GPS] and ensure that the expectations of the public are going to be met?” asked Dr. Bradford Parkinson as he opened his presentation this morning (Tuesday, April 15) at the European Navigation Conference, ENC-GNSS 2014 in Rotterdam, The Netherlands. Parkinson went through his 61-slide, 50-minute briefing on what he called “PTA” — Protect, Toughen, and Augment — a proposal concerning not only GPS but PNT systems globally. An article by Parkinson based...

  • Locata Warns: Lessons to Be Learned from GLONASS Spasm

    Calling it an “unprecedented and deeply worrying total disruption . . . [that] shook the industry,” Locata Corporation reiterated its call for redundant terrestrial systems to back up GNSS in the wake of the April 1 11-hour GLONASS system outage. Nunzio Gambale, Locata CEO, said “We have been telling the industry for years that you cannot have a critically important capability like GPS without also having a backup! What is Plan B if the satellite systems fail? What replaces the space...

  • Technology Intersection – Geospatial Strategies for Insight from Big Data

    Sensing technologies are producing unprecedented amounts of data about the environment and the digital world. The current question is: how can we gain true insight from all the available measurements? Industries are orienting development towards new systems built around higher requirements of performance and scale. Effective storage is an important precondition for big data analytics, but insight is ultimately related to the nature of collected data and where it originated....

  • Indoor GNSS Positioning Research Employs Spectra Precision Equipment

    Researchers at Telecom SudParis are working on a solution to provide indoor continuity for GNSS positioning. The idea is to deploy a minimal transmission infrastructure in order to allow a standard receiver to measure pseudo-ranges and carrier phases, thus leading to an indoor accurate positioning. The infrastructure consists of a few antennas fed through optical fibers with a GNSS-like signal. Based in Paris, Telecom SudParis is a part...
