    Septentrio announced today that Raven Aerostar, a manufacturer of Lighter-Than-Air (LTA) platforms, has successfully integrated Septentrio’s AsteRx2eH, a single-board dual-antenna GPS/GLONASS heading receiver, into its tethered aerostat systems.

    Raven Aerostar recently completed a maritime persistent surveillance solution demonstration, deploying a TIF-25K aerostat system aboard the High-Speed Vessel — SWIFT (HSV-2), during which the AsteRx2eH performed remarkably, according to the companies. Integrating the single-board AsteRx2eH dual-antenna receiver to replace a solution based on two separate GNSS receivers allowed Raven Aerostar to achieve a reliable and accurate heading solution while also decreasing deployment time and total cost of GNSS sensors.

    The AsteRx2eH provides a compact and low-power solution for precise positioning combined with accurate heading information, produced at a high output rate. The tracking of both GLONASS and GPS satellites allows the receiver to improve the availability and robustness of a solution in challenging environments.

    The AsteRx2eH is a globally acclaimed OEM solution with field proven performance for land, marine and aerial applications, Septentrio said. It is used onboard helicopters and aerostats during stabilized flights hovering at low dynamics, where inertial sensors cannot easily provide a drift free solution. Another application is delivering reliable heading information for driverless ground vehicles, even at very low speeds.

    “From its user interface to its accuracy and durability, Septentrio’s AsteRx2eH receiver has proven to be an exceptionally stable system,” commented Patrick Lokken, Engineering Technician at Raven Aerostar. “We have integrated the AsteRx2eH into our lighter-than-air applications in multiple environments including desert and maritime, and have yet to see it falter.”

  • Trimble TirePulse System Monitors Fleet Health

    Trimble has introduced the TirePulse Tire Monitoring System to assist fleet managers in reducing maintenance costs, increasing overall fleet productivity and promoting site safety. Part of the Trimble Connected Site portfolio, the advanced machine monitoring solution wirelessly reports tire temperature and pressure data from the jobsite to the VisionLink fleet, asset and site productivity management solution from Trimble. Automatic, real-time tire pressure and high-temperature alerts help fleet managers and site supervisors schedule cost-effective preventative tire maintenance, extend the life of tires, increase fuel efficiency and avoid dangerous blowouts.

    Under-inflated tires can reduce fuel economy, increase overheating, tread wear and blowouts that take a machine out of production. Together, these factors can significantly affect fleet productivity and operating costs.

    Trimble TirePulse can improve tire life while also reducing the need for fleet managers to drive to the site and visually inspect inflation, tire wear and temperature. Using a Trimble TP920 Industrial Tire Sensor in the tire valve stem and a Trimble SNM940 Connected Site Gateway for communications, the information is automatically relayed back to the office for analysis by the fleet manager. Accurate data is communicated through VisionLink, so the fleet manager can proactively manage tire maintenance on more machines across construction sites. Better preventative maintenance can result in improved fleet costs.

    The Trimble TirePulse system also promotes increased jobsite safety by reducing the risk of tire blowout and injury to workers. Properly inflated tires improve the performance of vehicle braking systems and allow a faster response time in potentially dangerous conditions. The system is also safer and more accurate than manual visual inspection because it does not require personnel to be in close proximity to overheated tires on heavy machinery.

    VisionLink automatically alerts the fleet manager or site foreman when a tire experiences a 20 percent drop in pressure and becomes a potential hazard. It can also provide a high-temperature alert to indicate that jobsite conditions are likely to accelerate tire breakdown.

    “Preventative maintenance is more cost effective than a machine going down suddenly with a blown tire. But with equipment moving around so much from site to site, fleet managers struggle to stay ahead of the game,” said Julian Dann, business area director for machine control. “TirePulse is priced for installation across the entire fleet of on- and off-road machine tires, regardless of make, model or manufacturer. Increased wear or breakdown can be reported and acted upon proactively. The system can often pay for itself by preventing just one blowout.”

  • Chronos Releases Handheld GPS Jamming Detector

    ctl3520-handheldU.K. firm Chronos Technology has released the CTL3520 handheld GPS Jamming Detector and Locator System. Aimed specifically at detecting GPS jammers hidden in vehicles, the unit can pinpoint even the weakest jammer and identify the vehicle in which the jammer is hidden, even in a busy multi-storey car park, Chronos said.  Other applications include detecting vehicles with jammers at ports, fleet depots, airport car parks and taxi ranks.

    The CTL3520 device was recently tested by representatives of law enforcement and security agencies in screened rooms at the MIRA test facility in Warwickshire and successfully identified hidden jammers both in vehicles and people’s pockets.

    The CTL3520 was developed from research undertaken by the University of Bath and is a significant commercial outcome of the Sentinel research project, which was partly funded by the Technology Strategy Board.

    “Previous jamming detecting products have been unable to identify which vehicle is hosting the jammer,” said Charles Curry, founder and managing director of Chronos Technology Ltd. “This has been a particular limitation and a major challenge for people wishing to protect critical infrastructure if faced with GPS jamming emanating from a nearby vehicle. Most websites currently selling GPS jammers maintain that the operating distance of a jammer is just a few meters. This is simply not true. We have tested GPS jammers in controlled trials and their range is easily 250/300 meters which makes specific vehicle identification extremely difficult, particularly in a multi-storey car park. The CTL3520 solves this problem and can pick out one vehicle in a thousand which has the jammer installed.”

    “This product contains advanced technology which is the culmination of more than two-years of research and development at the University of Bath, funded by the Engineering and Physical Sciences Research Council (EPSRC) within the Sentinel project. We are delighted that our collaboration with Chronos has led to a commercial product,” said Robert Watson, University of Bath Electronic & Electrical Engineering Department.

    In addition to UK users, Chronos is seeking international resellers and distributors to take the product into critical infrastructure protection and law enforcement markets where there is a recogniszd concern about the proliferation of low cost GPS jammers used by criminals to cover their tracks or vehicle drivers for personal privacy purposes.
