How drones are used in marine surveys

A Demonstration of Apache6 USV for the General Directorate of Water Management (OVF) in Hungary The context of the marine drone demonstration. On December 8, 2020, the Department of Spatial Data Technical Service organized a one-day workshop in Kis-Balaton, with the participation of the Trans-Danube Water Council. During this event, CHC Navigation and Norbit Hungary (a global provider of multibeam sonars) conducted a demonstration to present the capability of the Apache6 USV for the Directorate General of Water Management (OVF). How using drones in marine survey can increase productivity? During the live demonstration, experts from CHC Navigation and Norbit presented the characteristics, operation and results of advanced bathymetric survey measurements with unmanned marine drones. The Apache6 USV is easy to install and operate. Weighing only 15 kg, two operators can handle most remote deployment conditions. Like an aerial drone, the Apache6 has an auto-return feature and uses sonic radar (sonar) to avoid obstacles. Its fully autonomous survey mode is powered by the absolute straight-line CHCNAV technology, so the vessel follows a predetermined trajectory even under adverse current conditions. The 2020 Edition of the Apache6 USV (unmanned surface vessel) was launched in May 2020. It combines a dual GNSS positioning and heading sensor, stable and reliable hull attitude and an inertial measurement unit (IMU). CHCNAV's GNSS/INS control unit maintains high accuracy during GNSS transient outages, assuring uninterrupted surveying while passing under bridges. How using LiDAR scanners can extend the boundaries of marine survey applications? In addition to 3D bathymetric surveys, marine drones are used for the positioning of underwater objects, construction of ports, offshore installations, underwater archaeology, marine salvage and wreck removal. The CHCNAV Apache USV Series are equipped with high-performance single-beam or multibeam echo sounder and can be complemented with a surface LiDAR to create a combined high-precision marine and terrestrial 3D survey in a single pass, such as for port and river surveys with height clearance evaluation.

CHCNAV's GNSS receivers contribute to measuring the Everest's peak height

Shanghai, China - December 8, 2020 – CHC Navigation (CHCNAV). China and Nepal jointly announced today that the height of Mount Everest is 8,868.86 meters. This is a historic moment for CHCNAV since our P5 geodetic GNSS receiver successfully contributed to the peak elevation survey. It also demonstrates CHCNAV's technological success as a major player in the GNSS surveying and mapping industry and confirms BeiDou as a major part of the GNSS systems. Re-measurement is essential because the height of Everest is constantly changing. The most recent example is the Gorkha earthquake of 2015 - most geologists and scientists agree that Mount Everest may have shrunk by about 3 cm and may have moved southward by a meter or more. Apart from this earthquake, the height is also subject to precipitation, wind and global warming. It is estimated that the peak undergoes tectonic uplift of about 1 cm per year. In addition, the height assessment has also changed with technological progress in surveying technology. The reason why it is difficult to measure the height of Mount Everest is the presence of extreme temperatures and abnormal atmospheric pressure. At more than 8,800 meters above sea level, with extreme temperatures, below -45°C, and a low atmospheric pressure, only 30 kPa (compared to the normal 101 kPa), every movement of the surveyors is significantly difficult because of their protective clothing against the cold and the lack of oxygen. The operation of the equipment must therefore be as efficient as possible. In this kind of scenario, people experience the physiological challenge of climbing Mount Everest, following the same logic as the GNSS receiver itself. Efforts to achieve the measurement mission must overcome environmental obstacles. The GNSS receivers, provided by CHCNAV, have already passed rigorous testing and have been optimized to ensure the success of the mission. CHCNAV technical team optimized the receivers to adapt to the extremely low temperature. The CHCNAV R&D department redesigned the lithium-ion batteries to provide 12 hours of operation even at low temperatures, changed the antenna cable materials to a composite to avoid any cracking or signal attenuation. On May 28, 2020, China's National Geodetic Survey Team conducted the 2020 Mount Everest Elevation Survey. 30 of the 60 points of the GNSS control network have been measured with CHCNAV GNSS receivers, including 3 of the 6 points of intersection of the Everest elevation. The CHCNAV P5 GNSS receiver finally reached the summit and successfully completed its assigned mission. The results of this surveying mission provide an important data support for the Mount Everest peak elevation survey, as well as an additional input for its ecological and environmental protection, geological survey, monitoring of crustal movement, topographic mapping, etc.

CHC Navigation introduces the i73 GNSS and iBase GNSS receivers

FOR IMMEDIATE RELEASE CHC Navigation introduces the i73 GNSS and iBase GNSS receivers The power of IMU-RTK GNSS technology that fits in your hands and a fully integrated GNSS base station add a new scale to GNSS surveying applications. Shanghai, China - September 9, 2020 - CHC Navigation (CHCNAV) today announced the immediate availability of the i73 GNSS, a versatile pocket-sized IMU-RTK GNSS rover with an integrated inertial module and the iBase GNSS, a rugged base GNSS receiver. The combination of the i73 GNSS and the iBase GNSS offers the most productive and affordable solution for measuring and staking out points in any surveying, mapping, or construction application. "Surveyors and construction professionals are forced to carry heavy and cumbersome GNSS receivers in most situations, resulting in unnecessary fatigue and lower productivity," said Hans Huang, product manager of CHC Navigation's Survey and Engineering Division. "Taking this into account, we have developed our pocket-sized i73 GNSS, the lightest GNSS rover powered by the latest IMU-RTK technology, and much more. Our iBase GNSS station follows the same concept of an all-in-one solution, making the need for external radio modems and other bulky accessories obsolete". The i73 Pocket IMU-RTK GNSS | A new scale to GNSS Best-in-class technology but at an affordable price. The i73 GNSS offers superior GNSS signal tracking enabling surveys beyond the usual constraints. It features full 624-channel GNSS technology and connects seamlessly to RTK GNSS networks as well as to UHF GNSS station over its embedded UHF modem. Automatic pole-tilt compensation. The i73 GNSS internal interference-free inertial module (IMU) allows automatic pole tilt compensation of up to 45 degrees. Projects are completed 30% faster and with increased efficiency and safety when measuring hard-to-reach points. Weighs less, works longer. The i73 takes GNSS to a new scale. With only 730 g and 15 hours operating time, the i73 GNSS is one of the lightest and most rugged RTK GNSS receivers on the market. Easy to carry and use, the i73 will not tire you out. The iBASE GNSS | Redefining the concept of GNSS base station The GNSS iBase is a fully integrated GNSS base station, specifically designed to meet 95% of surveyors' needs when working in UHF GNSS base and rover mode. The performance of the iBase UHF base station compared to a conventional external UHF radio modem is virtually identical. But its unique design eliminates the need for a heavy external battery, bulky cables, an external radio, and a radio antenna. Its 5-watt radio module provides operational GNSS RTK coverage up to 8 km.
