Hi-Target Launches New GNSS RTK Receiver

Hi-Target, the Chinese manufacturer of high-precision geographic instruments, recently announced the release of the V90 Plus, the company’s next-generation GNSS RTK. The V90 Plus is equipped with the advanced Trimble BD970 OEM and delivers centimetre accuracy for a variety of applications. The full-wave RTK antenna based on air dielectric technology supports the whole constellation and makes it much lighter and more stable. Furthermore, thanks to the built-in Linux operating system and multiple pre-loaded smart applications such as tilt surveying, electronic bubble calibration, NFC and voice DIY, the V90 Plus GNSS system enables the surveyor work more conveniently. With the V90 Plus, Hi-Target aims to provide the surveyor with an industry-leading GNSS solution with improved accuracy and stability. Especially the self-developed antenna, based on air dielectric technology, is designed for multipath mitigation. It is not only lighter than traditional RTK antennas, but also effectively avoids the instability of ceramic dielectric antennas. Every detail of the V90 Plus is optimised to improve the performance.... (read more)

Medium-format Cameras for High-accuracy Mapping

Field Test of the Phase One iXU-RS1000 Camera
Small and medium-format cameras are increasingly gaining popularity for mapping small and medium-size areas, corridors, construction sites and cities. They are also used as companions of Lidar systems, mounted on unmanned aerial systems (UASs), and for monitoring and inspecting infrastructure. The author of this article investigated the suitability of the Phase One iXU-RS1000 camera for high-accuracy mapping and found this medium-format camera to be a metric camera with stable and clearly definable interior orientation parameters, producing images of high geometric and radiometric quality. In photogrammetry it is important that cameras produce images of which the geometric distortions are as small... (read more)

Precise UAV Camera Positioning for 3D Mapping

Photogrammetric mapping is the new 'hot topic', although the concept has been around since Leonardo da Vinci's time and it has been in use in practice for over a century. Drone technology has now consumerised photogrammetry, introducing data acquisition and 3D model processing to thousands. From a surveying standpoint, accuracy is key. To build 3D models in a known spatial frame of reference requires some form of control, either on the ground, in the air or a combination of both, which is where ground control points (GCPs) come in. GCPs provide a solid tie to a real coordinate system with known coordinates... (read more)

Smart LF Scanner

Colortrac (UK) has launched the Smart LF, a large-format document scanner for professional and corporate users in any size of enterprise. It uses digital imaging technology, Contact Image Sensors (CIS) normally found in small-format, flatbed desktop scanners. Several ‘deep focus’ CIS devices have been combined to create a digital scanner capable of high speed, 2,400 dpi input in 24-bit colour or black & white from originals up to 40" wide. The scanner provides instant scans from power-on, with fully automatic colour calibration, no sensor alignment and low power consumption. It is available in three models, with a range of standard...

DT20 Series Digital Theodolites

Sokkia is releasing a new digital theodolite series, the DT220, DT520, DT520A and DT620, with as a main distinguishing feature an improved power-saving technology. The DT620, recently set a world record for continuous operating time of 220 hours.   The DTx20 series digital theodolites maintain the charachteristics of previous DTx10 models, such as the industry's highest IP66 dust- and water-protection rating, advanced absolute rotary encoders that ensure long-term reliability, as well as user-friendly operation.   Other improvements, compared to the ancestors, are doubled operating time: model DT620 achieves an operating time of 220 hours with two R14 alkaline batteries. The... (read more)
