Trimble has introduced data integrity monitoring for CenterPoint RTX Fast, its Precise Point Positioning (PPP) correction service.
The Trimble RTX Integrity monitoring system is an innovative, patented solution designed in direct response to customer requirements for production-ready applications. It continuously validates the reliability of correction data processed by the network, which is delivered to users in the agriculture, geospatial, construction and automotive industries, ensuring that positioning data is correct the first time. .
Using a two-step process, the Trimble RTX Integrity system verifies the integrity of GNSS data and filters out erroneous information in the network server before the data is released. Post-broadcast secondary verification is performed on the entire data transmission process where additional errors can be detected and removed.
The integrity monitoring system is fully automated and reacts in seconds to detect, isolate and block faulty data to provide even more accurate and reliable positioning.
Trimble RTX Integrity is comprised of independent monitoring stations strategically positioned on RTX Fast networks in the United States, southern Canada and throughout Europe. These stations continuously monitor data output during several stages of the Trimble RTX positioning process. All suspicious satellite data is removed during the integrity protection process and positioning is calculated using only validated data.
Trimble Alloy GNSS reference receivers power independent monitoring stations using redundant internet connectivity for increased reliability. To date, no other positioning network offers the same level of data integrity validation over such large and contiguous geographic areas.
The Trimble RTX Integrity monitoring system was developed in accordance with Automotive Software Performance Improvement and Capability Determination (ASPICE) and ISO 26262 automotive safety standards, making it easy to integrate into leading automakers’ autonomous driving systems.
Trimble RTX Integrity can also be used by Trimble customers in the agriculture, geospatial, and construction industries to ensure correction flow integrity and reliability for applications such as machine control and high precision surveying applications.
“Trimble remains committed to exceeding expectations by delivering accurate fixes to our customers to support safety-critical and other day-to-day applications,” said Patricia Boothe, senior vice president of autonomy at Trimble. “Implementing additional checks and balances to ensure our data is authenticated, trusted and accurate is of paramount importance to maintaining the integrity of our RTX network and instilling confidence in our users that the data is correct. .”
