The firmware works best with the recently launched TerraStar-X correction service, which delivers accuracy and reliability, as well as the OEM7, SPAN CPT7 and PwrPak7 products, which use signals from all GNSS constellations and frequencies to provide users with reliable autonomy and exceptional positioning availability.
The 7.07.03 firmware offers a significant improvement to the SPAN GNSS + INS (inertial navigation system) technology. SPAN with 7.07.03 shows improvements of up to 20% in the horizontal position over the entire SPAN IMU catalog and across various industry use cases including agriculture and marine. SPAN with 7.07.03 also provides improved motion detection, resulting in more robust time to convergence.
“The 7.07.03 firmware features improvements to both our SPAN Marine and SPAN Rail profiles that will greatly impact application performance and consistency,” noted NovAtel Director of Product Management, Neil Gerein, “The SPAN Marine Profile sees improvements to the heave performance and will allow users to start their work significantly faster thanks to a simplified setup for applications in marine dynamics. The SPAN Rail Profile improves position accuracy over long GNSS outages, which is crucial for applications in rail environments that often deal with potential signal obstructions such as trees, tunnels and dense urban areas.”
