    Septentrio launches mosaic-T GNSS receiver

    Lurker
    By Lurker,
    Septentrio has launched the mosaic-T GPS/GNSS receiver module, built specifically for resilient and precise time and frequency synchronization under challenging conditions. According to the company, its multi-frequency, multi-constellation GNSS technology — together with AIM+ Advanced Interference Mitigation algorithms — allows mosaic-T to achieve maximal availability even in the presence of GNSS jamming or spoofing. This compact surface-mount module is designed for automated assembly and h

    SBG Systems advances GNSS/INS with 3rd-generation Ellipse

    By Lurker,
    SBG Systems has announced the third generation of its Ellipse series of miniature inertial sensors. The renewed product line benefits from a 64-bit architecture, allowing high precision signal processing. All of the INS/GNSS devices now embed a dual-frequency, quad constellations GNSS receiver for centimetric position and higher orientation accuracy. SBG Systems manufactures miniature high-accuracy inertial navigation systems with inertial measurement unit (IMU) design, calibration and

    Facebook Acquire Mapillary

    Lurker
    By Lurker,
    The big news in the geospatial world at the moment is Facebook’s acquisition of Mapillary. For those unfamiliar, Mapillary is a darling of the mapping world and one of the highest-profile geospatial startups of the last decade—launched in 2013, their mission was to create a global street-level imagery dataset to rival Google Street View. Mapillary was the prototypical “venture-scale” business — preposterously ambitious, technically impressive, inarguably valuable for the world, and plausibl

    GPS III SV-08 ‘born’ with core mate complete

    Lurker
    By Lurker,
    The United States Space Force’s GPS III program reached another milestone with the successful core mate of GPS III Space Vehicle 08 at Lockheed Martin’s GPS III Processing Facility in Waterton, Colorado, April 15. With core mate complete, the space vehicle was named in honor of NASA trailblazer and “hidden figure” Katherine Johnson. The two-day core mate consisted of using a 10-ton crane to lift and complete a 90-degree rotation of the satellite’s system module, and then slowly lowerin

    Using Satellite Imagery to Track Volcanic Ash Clouds

    Lurker
    By Lurker,
    Researchers have developed an algorithm that can distinguish between volcanic and non–volcanic clouds using high-resolution satellite imagery.  Called the Cloud Growth Anomaly (CGA) technique, the algorithm uses geostationary satellite data to detect fast growing vertical clouds caused by volcanic output.  Volcanic ash produced by eruptions are a major threat to airplanes.  In 2011, for example, Grímsvötn erupted, closing Iceland’s air space.  Volcanic ash can cause significant damage to airplan
