Fixposition develops autonomous guidance sensors with high-precision positioning that excel in challenging environments, such as urban canyons, underpasses, and under tree canopies. Combining high precision RTK-GNSS with inertial and visual sensors, our deep sensor fusion technology provides precise global positioning anytime, anywhere.
Precise global positioning everywhere – enabling autonomy at scale
Autonomous vehicles operating both on the ground and in the air require accurate positioning down to the centimetre to decimeter level. Traditional GNSS/GPS-based solutions cannot always provide this crucial capability under challenging conditions such as in urban canyons, under tree canopies, and inside buildings. Even GNSS-INS fusion is not enough to provide the required positioning accuracy in all environments.
Our state-of-the-art solution combines RTK-GNSS positioning with advanced inertial and visual sensors, allowing autonomous machines to know exactly where they are at all times with previously unachievable precision and accuracy.

Sophisticated Multi-Sensor Fusion Technology
Robust & precise positioning for autonomous vehicles
The Vision-RTK 2 system feeds all available sensor data into our deep sensor fusion engine, combining the best of GNSS and relative positioning to overcome weaknesses in individual sensors and remove the time-dependent drift characteristics present in IMU-based solutions. The result is robust and precise positioning even in GNSS-degraded or denied areas.
Our solutions include:
Sensor fusion
All available sensor data such as GNSS observations, camera images and IMU measurements are fed into Fixposition’s deep sensor fusion engine. Auxiliary inputs like wheel speed information can also be added to increase sensor performance in GNSS degraded or denied areas.
The fusion engine leverages the strengths of multiple independent sensor technologies and compensates for individual weaknesses to provide an optimal pose estimate.
RTK-GNSS
Two dual-band receivers use satellite signals from all four GNSS Systems (GPS, GLONASS, BeiDou, and Galileo) to determine the sensor’s absolute position and orientation.
Common errors in current GNSS systems require corrections to achieve the high-level of accuracy required. RTK technology is used to correct these errors and achieve centimeter-level accurate positioning. NTRIP is used to provide the correction data to the sensor. This data can be obtained from publicly available Virtual Reference Station (VRS) networks, or from a local physical base station.
Visual Odometry
Camera images are used to extract significant points (visual features) that are tracked across multiple images.
Subsequent observations of visual features allow computation of how the camera moved in between the captured images.
Professional evaluation and design support
We work with you to determine the specifics of your hardware and software platforms and the unique requirements of your application. An evaluation kit is available for easy prototyping and testing, and data can be uploaded for our engineers to assist you.
We can then fine-tune your design to optimize performance, and continue to support you during the production phase with software updates, feature requests and other upgrades.
The Vision-RTK 2 hardware and software is easily scalable for high-volume production runs.
