FIXPOSITION VISION-RTK 2 - A UNIQUE SOLUTION

Thanks to proprietary deep sensor fusion technology, reliable and accurate real-time positioning is no longer the preserve of the few. Fixposition's Vision RTK 2 is an easy-to-use, highly accurate position sensor that enables autonomous navigation systems to operate in a variety of challenging environments, whether it's in street canyons, underpasses, beneath tree canopies, or wherever conventional GNSS positioning systems fail. With Vision RTK 2, you can venture into exciting new territories.

Accurate positioning faces many challenges

From driverless shuttles to agricultural and urban robots, we are entering the age of autonomous machines. They all share a common challenge: they need to know exactly where you are, indoors or outdoors, in the city or under a canopy of trees.

Sensor fusion

All available sensor data such as GNSS observations, camera images and IMU measurements are fed into the Fixposition sensor fusion engine. Additional inputs such as wheel speed information can also be added to improve sensor performance in areas with poor GNSS connectivity. The fusion module leverages the strengths of multiple independent sensor technologies and balances the weaknesses of each to provide an optimal pose estimate.

Visual odometry

Extract important points (visual features) from camera images and track them across multiple images. Subsequent observation of the visual features allows you to calculate how the camera moves between captured images.

RTK Global Navigation Satellite System

Two dual frequency receivers use satellite signals from all four GNSS systems (GPS, GLONASS, Beidou and Galileo) to determine the absolute position and orientation of the sensor. Common errors in current GNSS systems require correction to achieve the required level of high accuracy. RTK technology is used to correct for these errors and achieve centimeter-level positioning. NTRIP is used to provide calibration data to the sensor. This data can be obtained from publicly available virtual reference station (VRS) networks or local base stations.
