Trimble introduced data integrity monitoring for its precise point positioning (PPP) correction service, CenterPoint RTX Fast. The RTX Integrity monitoring system continuously validates the reliability of correction data processed by the network, ensuring positioning data is right the first time.
The Trimble RTX Integrity system verifies the integrity of GNSS data received from satellites and filters faulty information in the network server before the data is broadcast. A secondary post-broadcast check is conducted on the entire data transmission process where additional errors may be detected and removed.
According to Trimble Autonomy, the integrity monitoring system is fully automated and reacts in seconds to detect, isolate and block faulty data to provide even more highly accurate and reliable positioning.
Trimble RTX Integrity is comprised of independent monitoring stations strategically positioned across RTX Fast networks in the United States, southern Canada and across Europe. These stations continuously monitor data output during multiple stages of the Trimble RTX positioning process. Any suspicious satellite data is removed during the integrity protection process and positioning is calculated using only validated data.
Trimble Alloy GNSS reference receivers power the independent monitoring stations using redundant internet connectivity for added reliability.
