An overview of the latest products in the GNSS and inertial positioning industry in the May 2019 issue of GPS World Magazine.
PhaseStation ADEV frequency stability phase noise test system is a new type of signal source analyzer. It can test the signal performance of a large number of products, such as GPS or GNSS-compliant oscillators. It can also be used to verify and evaluate the local oscillator performance of the GNSS receiver design, including GPS TCXO evaluation and parameterization, or to perform stability measurements on 1PPS and any frequency output from the GNSS receiver. It also helps to optimize the design of the GNSS receiver Kalman filter through the 1PPS output signal of the GNSS receiver. It automatically synchronizes and synchronizes (calibrates) the internal dual oscillator DOCXO option to an external GNSS receiver through the 1PPS input. Jackson Labs, jackson-labs.com

Supports civil signals in the L5 frequency band
TAU-0707 is a multi-band, multi-GNSS module series. TAU-0707 measures 7.6 x 7.6 mm and supports GPS, Galileo, GLONASS, Beidou, QZSS, IRNSS and all civilian frequency bands (L1, L2, L5, L6). This module is a concurrent multi-band receiver, embedded with Cynosure III single-chip independent positioning chipset, which can provide multi-frequency measurement and simplify the integration of third-party applications. The TAU1206-0707 and TAU1205-1010 models are better in terms of multipath mitigation because the L5 signal has a higher fragmentation rate relative to the L1 C/A code. For professional applications, the module TAU1303-0707 built-in support for standard RTCM protocol (MSM), supports multi-band and multi-system high-precision raw data output, including pseudorange, phase range, Doppler, signal-to-noise ratio, etc.—Party’s Integration and application.

The system improves the safety and speed of drilling and piling contractors
The Groundworks machine control system enables contractors to perform drilling and piling operations with centimeter-level accuracy. Using the touch screen display, the operator can personalize the interface through configurable views. The software is consistent with other solutions in the Trimble Civil Engineering and Construction product portfolio. Pileless navigation reduces rework and reduces the need for personnel working near the machine during operation. The contractor can drill to the specified location, depth, direction and inclination. By optimizing the drill hole spacing, angle and machine position to obtain a more uniform blasting pattern, better rock crushing and lower transportation costs can be achieved. Automatically stop to reduce over-drilling. Automatic quality assurance and quality control reports include capture start and end locations, time, altitude, and actual embedding depth.

Virtual Surveyor now enables users to handle larger projects without having to purchase more powerful computers or cloud services. Version 6.2 solves the problem of large files by providing enhanced trimming and inlay functions. Users can merge multiple processed orthophotos and digital surface models into one project and use new editing tools to create smooth edges. The mosaic can then be exported as a new TIFF file or used as the basis for a virtual survey of the entire region. The 3D Fly Through function allows users to select space bookmarks and waypoints, and create movies that allow viewers to fly through terrain. Virtual surveyor, virtual-surveyor.com

The compact HiPer VR uses a rugged IP67 design with advanced GNSS. Its GNSS chipset has universal tracking channel technology that can automatically track each satellite signal (GPS, GLONASS, Galileo, Beidou, IRNSS, QZSS, SBAS). It also has an integrated 9-axis IMU and a 3-axis electronic compass. TILT (Topcon Integrated Leveling Technology) is designed to compensate for errors outside the plumb range and to level field measurements up to 15 degrees. HiPer VR can be used for static or dynamic GNSS post-processing measurement, as a network RTK rover and FC-5000 internal 4G/LTE cellular modem, as a UHF/FH/Longlink site RTK rover, and also a patented hybrid positioning by Topcon In the work process.
