- OXTS gx/ix™ GNSS Tight Coupling Technology
RTK processing and enhanced urban performance
gx/ix™ is OXTS’ proprietary software application that provides users with an increased amount of time spent with accurate data where GNSS conditions are difficult. It is made up of OXTS’ RTK/PPK navigation processing engine and tightly-coupled integration of the GNSS and IMU sensors.
Whether you’re using an OXTS Inertial Navigation System (INS) for Automotive, Autonomy or Survey and Mapping based applications OXTS devices with gx/ix™ enabled will give you more accurate data for longer!
GNSS Tight Coupling Technology
Model:
gx/ix™
Maker:
OxTS
Features
Environments such as urban canyons, bridges, and tree cover can be a nightmare for GNSS-based systems due to multipath, reduced satellite visibility, and complete outages. gx/ix™️ offers some key features that help deal with these environments:
Single satellite aiding
Tight-coupling of the GNSS and IMU with gx/ix™️ means that even when fewer than 4 satellites are visible, the raw GNSS data from any available satellites is still integrated into the navigation solution to provide updates and greatly reduce position drift
Inertial relock
RTK relock time after brief obstructions (bridges/tunnels etc) is also improved with our “inertial relock” feature which uses the IMU data to reduce the GNSS search area after the satellite outage ends
Mixed mode
Our “Mixed mode” option for RTK processing which means that the INS’ kalman filter will intelligently switch between the GNSS reciever’s own RTK engine (very good in open-sky) and OXTS’ gxRTK engine (perfect for poor GNSS environments) when you are driving in and out of poor GNSS conditions e.g past tree lines or tall buildings. This means you stay in corrected position mode for longer.
Multiple RINEX file processing
Now with gx/ix™️ processing, if you have logged base station corrections locally or can download them from a CORS network, you can add up to 255 files per processing run in our NAVsolve post-processing software and achieve the highest accuracy, down to the centimetre.
