Accurate and robust ground-truth data, without the need for post-processing

Company News December 18, 2017

Save time by making use of OxTS’ exclusive gx/ix™ real-time position algorithm, now in real-time RTK mode.

New firmware available for OxTS devices

We are delighted to announce an exciting update to our technology. For some time, customers have utilised our gx/ix algorithms to improve position performance when they are post-processing data sets.

Our gx/ix technology combines position calculations from raw GNSS measurements with single-satellite aiding techniques when satellite visibility is poor. This means accurate position and heading measurements are output by our devices in urban canyons, through bridges and other obstructions.

The gx/ix RTK feature can now be utilised in real-time, achieving RTK position accuracy where satellite visibility is minimal (fewer than 4 satellites in view). If your device has gx/ix RTK enabled, upgrading to the latest firmware will add the benefits from this update.
