The PhaseStation ADEV Frequency Stability phase noise test system is a new signal source analyzer. It tests signal performance in a host of products such as GPS- or GNSS-disciplined oscillators. It can also be used to qualify and evaluate local oscillator performance for GNSS receiver design, including GPS TCXO evaluation and parametrization, or to take stability measurements of 1PPS and arbitrary frequency outputs from GNSS receivers. It is also useful in optimization of GNSS receiver Kalman filter design via the GNSS receiver 1PPS output signals. It automatically synchronizes and syntonizes (calibrates) the internal dual oscillator DOCXO option to external GNSS receivers via 1PPS input.

The TAU-0707 is a multi-band, multi-GNSS module series. Within its 7.6 x 7.6 millimeter size, the TAU-0707 supports GPS, Galileo, GLONASS, BeiDou, QZSS, IRNSS and all civil bands (L1, L2, L5, L6). The module is a concurrent multi-band receiver embedded with a Cynosure III single-die standalone positioning chipset, which offers multi-frequency measurements and simplifies integration for third-party applications. The TAU1206-0707 and TAU1205-1010 models are better in multipath mitigation due to the higher chipping rate of L5 signals relative to L1 C/A code. For professional applications, module TAU1303-0707 comes with built-in support for standard RTCM protocol (MSM), supporting multi-band multi-system high-precision raw data output, including pseudorange, phase range, Doppler, SNR for any kind of third-party integration and application.

The GT-88 timing module and GF-8801/02/03/04/05 disciplined oscillator are for users who require UTC time-synchronized signals (1 PPS/10 MHz) to meet the new 5G requirements. Achieved stability is better than that of an atomic clock, including rubidium. The GT/GF-88 series includes an algorithm, Dynamic Satellite Selection, that provides outstanding multipath mitigation in urban canyon environments. It support GPS, GLONASS, QZSS and Galileo.

Machine control

System improves safety, speed for drilling and piling contractors


Photo: Trimble

The Groundworks Machine Control System enables contractors to perform drilling and piling operations with centimeter-level accuracy. Using a touchscreen display, operators can personalize the interface with configurable views. The software aligns with other solutions in the Trimble Civil Engineering and Construction portfolio. Stakeless navigation reduces rework and decreases the need for personnel working near the machine during operation. Contractors can drill to the specified location, depth, orientation and inclination angle. Better rock fragmentation and lower hauling costs can be achieved by optimizing drill-hole spacing, angles and the location of the machine for a more even blasting pattern. Auto stop reduces overdrilling. Automated quality assurance and quality control reporting includes capture of start and end positions, time, elevation and actual embedment depth.

Survey software

Improved for UAV use

Virtual Surveyor now enables users to process larger projects without buying more powerful computers or cloud services. Version 6.2 solves the problem of large files by offering enhanced clipping and mosaicking functionality. Users can merge multiple processed pieces of orthophotos and digital surface models into a single project, and create smooth edges with the new clipping tool. The mosaic can then be exported to a new TIFF file or serve as the basis for a full area virtual survey. A 3D Fly Through capability allows users to select spatial bookmarks and waypoints and create a movie that allows the viewer to fly through the terrain.

The compact HiPer VR features advanced GNSS in a rugged IP67 design. Its GNSS chipset has Universal Tracking Channels Technology that automatically tracks every satellite signal (GPS, GLONASS, Galileo, Beidou, IRNSS, QZSS, SBAS). It also has an integrated 9-axis IMU and 3-axis eCompass. TILT (Topcon Integrated Leveling Technology) is designed to compensate for mis-leveled field measurements out of plumb by as much as 15 degrees.The HiPer VR can be used for static or kinematic GNSS post-processed surveys, as a network RTK rover with the FC-5000’s internal 4G/LTE cellular modem, as a UHF/FH/Longlink jobsite RTK rover, and also in Topcon’s patented Hybrid Positioning workflow.

The Hangar Repeater Solution enables aircraft ground engineers to undertake 24/7 avionics testing of GPS, Inmarsat and Iridium satellite signals indoors. Aircraft engineers can undertake testing of aircraft regardless of weather, without having to move aircraft in and out of a hangar. The dedicated repeater reduces on-ground time, work hours and overall maintenance costs, and provides communication inside buildings or underground without the need for direct line of sight to the sky.

The GPS 3000 is a compact, remote-mount 15-channel GPS receiver capable of five position updates per second. It uses enhanced WAAS/SBAS signals to provide ultra-precise, DO-260B-compliant position data. It provides an ARINC 743A-5 GNSS interface over an industry-standard ARINC 429 data bus for those who wish to integrate GPS 3000 with existing avionics systems. When so configured, the GPS 3000 sensor can provide position source information to the FMS, meeting requirements for required navigation performance (RNP) and supporting GPS-based vertical approach capability for coupled LPV approaches and other next-generation flight applications.
