Vision-RTK enables applications in previously unreachable areas and unlocks new possibilities for autonomous ground robots and drones

At this year’s Intergeo Digital event, taking place Oct. 13-15, Fixposition is debuting the Vision-RTK positioning sensor, a compact centimeter-accurate solution with high reliability and availability in environments that are challenging for traditional GNSS.

The Vision-RTK’s sensor-fusion algorithm is based on the deep integration of satellite, camera and inertial sensors, and enables unprecedented reliability and availability in diverse and challenging applications, the company stated.

“The highly integrated nature of our Vision-RTK sensor and our deep expertise in computer vision and real-time kinematic (RTK) GNSS enabled us to implement completely new approaches in sensor fusion, resulting in previously unseen performance,” said Lukas Meier, CTO and co-founder of Fixposition.

Traditional GNSS sensors suffer from limited reliability in GNSS-challenging and denied areas. On the other hand, standalone computer vision is sensitive to light conditions (such as snow, strong sunlight and rain) and struggles in situations where there is a lack of features such as cornfields and grass. Errors accumulate over time with standalone inertial technology, causing large drifts.

As a result, devices using either sensor are limited in their range of operation and are likely to fail in certain conditions. Fixposition’s solution increases the potential of these sensors with its unique sensor-fusion technology by increasing the trustworthiness of the positioning accuracy and the range of operation in different environments.

The real-time sensor fusion provides centimeter-accurate absolute positioning at any time, in any outdoor environment. This small module  integrates two RTK-GNSS receivers and visual inertial navigation, and is suitable for applications where size and accuracy are of paramount importance.

The dual-receiver configuration, together with Fixposition’s advanced algorithms, provides a true-heading output and increased resistance to electromagnetic radiation.

The sensor provides USB and Wi-Fi connectivity and a web interface. It enables straightforward integration in state-of-the-art autopilot control systems for drones and robots. It’s also plug-and-play compatible with platforms such as PX4, ROS and Apollo.

For ground robotics and drones applications, Vision-RTK increases the device uptime and efficiency while enabling new market segments in areas previously inaccessible. For end-device manufacturers, this technology eliminates the need for an in-house development of advanced localization solutions, shortening their sales cycle and reducing costs and investments.
