New Trimble RTX Integrity Monitoring System Validates Reliability of Correction Data

The new Trimble RTX Integrity monitoring system can be leveraged by the agriculture, geospatial, construction and automotive industries to ensure the correction data they’re receiving from the company’s precise point positioning (PPP) correction service, CenterPoint® RTX Fast, is accurate.

The system does this via a two-step process, verifying the integrity of the GNSS data received from satellites and then filtering out faulty information in the network server before the data is broadcast, according to a news release. It performs a secondary post-broadcast check on the entire data transmission process to detect and remove errors. The fully automated system reacts in seconds to detect, isolate and block faulty data to ensure even more reliable positioning for safety-critical applications.

Independent monitoring stations are positioned across RTX Fast networks in the U.S., southern Canada and Europe to monitor data output during multiple stages of the positioning process. Suspicious satellite data is removed, with position calculated only using validated data.

For added reliability, Trimble Alloy™ GNSS reference receivers power these monitoring stations using redundant internet connectivity.

The system was developed in accordance with Automotive Software Performance Improvement and Capability dEtermination (ASPICE) and ISO 26262 automotive safety standards and can be easily integrated into automotive manufacturers’ autonomous driving systems. Customers in the agriculture, geospatial and construction industries also can use the system to ensure correction stream integrity and reliability for applications like machine control and high-accuracy surveying applications.

“Trimble remains committed to exceeding expectations by providing accurate corrections to our customers to support safety-critical and other day-to-day applications,” said Patricia Boothe, SVP of autonomy, Trimble, according to the release. “Implementing additional checks and balances to ensure our data is authenticated, trustworthy and accurate is of paramount importance to maintaining the integrity of our RTX network and instilling confidence with our users that the data is correct.”
