Trimble has added capabilities to its real-time network (RTN) portfolio, including the Trimble Pivot Platform and the Trimble Alloy GNSS reference receiver.
The new capabilities will enable operators to continue to meet the ongoing demand from surveyors, mapping professionals and precision farmers for accurate, reliable corrections derived from real-time networks.
The announcement was made at Intergeo 2019, the world’s largest conference on geodesy, geoinformatics and land management, taking place Sept. 17-19 in Stuttgart, Germany.
Boosting RTN performance. A well-established network software, the Pivot Platform manages and controls small, mid-size and countrywide GNSS networks. By applying sophisticated atmospheric models to reduce systematic errors, highly accurate GNSS corrections are generated and made available for a wide range of field applications.
BDS-3 now supported
Both Pivot and Alloy now access BeiDou Generation III (BDS-3) signals.
Trimble Pivot version 4.3 has been enhanced to track and store BDS-3 — RTN operators worldwide now have the ability to provide their customers with additional satellite signals to offer even more robust and reliable positioning for their applications. This update also includes a simplified Chinese user interface, providing easy-to-use software operations for Chinese RTN operators.
Released in 2018, the Alloy GNSS reference receiver was designed with the processing power needed to deliver high-quality data from multiple GNSS constellations. Alloy version 5.42 firmware tracks all available and planned GPS Block IIIA L1C and BDS-3 signals, empowering operators with a full GNSS constellation dataset.
“These updates keep the Trimble Pivot Platform and Alloy on a future driven path,” said Mark Richter, strategic marketing director, Real-Time Networks and Services portfolio for Trimble’s Advanced Positioning Division. “Our focus is to continue to deliver enhancements influenced by market demands and advancements in technology, which deliver next-generation RTN hardware and software to our customers.”
The Trimble Pivot Platform and Trimble Alloy GNSS reference receiver updates work in conjunction to provide quality GNSS corrections to network operators and end users.
