  • Low Environmental Impact Cabling Using GPS

    Jan De Nul’s Moonfish cable trencher on its maiden outing © JdN Need to lay 5 km of cabling through an environmentally sensitive area in 5 days? Sounds like a job for Sunfish, Moonfish and Isaac Newton. A New Offshore Windfarm The Race Bank windfarm, located about 27 km (16.8 mi.) off the Norfolk coast in England, […]

  • Drone Inspections Go Nuclear with GPS and RADAR

    High-precision GPS receivers mounted on drones able to identify 1 mm hairline defects in cooling towers Drones Rise To The Challenge How do you inspect a structure that’s almost 160 m high and 120 m in diameter? With a few weeks to spare, a crash course in abseiling and head for heights, you could certainly […]

  • GPS Spoofing: Is Your Receiver Ready for an Attack?

      Will Spoofers Eat My Children? GNSS users have long been wary about threats from jamming and now a new GNSS bogeyman has appeared. Unlike jamming which is intended to block GNSS signals, spoofers are altogether far more sinister. By replicating GNSS signals, a spoofer can fool a receiver into thinking that it’s elsewhere in […]

  • 4 Constellations in 1 RTK XV

    In difficult conditions, multi-frequency, quad-constellation RTK can deliver over 40% more RTK availability than dual-constellation RTK More satellites in RTK for those hard-to-reach areas How many satellites do you need for precise and reliable RTK positioning? Evidence thus far suggests, the more the merrier. With this in mind and given that GPS and GLONASS are […]

  • Calibrating Scales: External vs. Internal

      Calibration is essential to ensure a weighing scale or balance’s accuracy. Frequent calibration shows the device is linear in its precision, allowing for more experiments with fewer chances of errors. There are two methods to do a calibration: internal and external calibration. The process for an internal calibration is simple, you calibrate with a […]

  • RSO: The Radiation Meter

    As part of meeting the requirements of the CNSC, applicants must have an available survey meter at any site of the licensed radioactive activity. A survey meter can also be used for emergency events involving the portable gauges, including crushing or other physical damage. The applicant may satisfy the requirements by having a calibrated survey […]

  • Drones: Rotary vs Fixed

      A drone is an unmanned aircraft and a flying robot. It can be remotely controlled manually or by software-controlled flight plans using onboard sensors and GPS. Drones may also be referred to as Unmanned Aerial Vehicles (UAVs). Initially UAVs were used for military purposes like surveying missions, anti-aircraft target practice, weapons research and intelligence gathering. […]

  • RSO: Transportation Basics

      Essential requirements must be satisfied before transporting nuclear gauges by a business or a carrier company. Private and Commercial carriers need both to comply with the rules and guidelines that are provided for them. Private carriers own the goods (nuclear gauge) being transported, and the transportation of the goods is incidental to their regular […]

  • The History of Concrete

    Concrete has been around since man started building things and now it is the most widely used human-made material around the world. Concrete is a composite material made from coarse aggregate bonded together with a fluid cement that hardens over time.    

  • GNSS in a Cold Climate

    Why all the fuss about Antarctica? It’s the coldest, driest and windiest continent on Earth which many might understandably prefer to leave well enough alone. It is however home to 70% of the world’s fresh water and 90% of all the ice on Earth which if it melted, would raise sea levels by almost 70 m (230 ft.) Being […]
