VISION-RTK 2 IP SENSOR Vision fixed position - RTK2 IP-Sensor Unit

Proprietary deep sensor fusion technology means that reliable and accurate real-time positioning is no longer reserved for a few. The Vision-RTK 2 from Fixposition is an easy-to-use, high-precision position sensor that enables autonomous navigation systems to work in a variety of challenging environments, whether in canyons, underpasses, under treetops or where conventional GNSS positioning systems fail everywhere. With Vision RTK 2, you can venture into exciting new territories.

There are many challenges to accurate positioning From driverless shuttles to agricultural and urban robots, we are entering the age of autonomous machines. They all have a common challenge: You need to know exactly where you are, indoors or outdoors, in the city or under a treetop.

Sensor fusion All available sensor data such as GNSS observations, camera images and IMU measurements are fed into the fixed position 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. The subsequent observation of the visual characteristics allows the calculation of how the camera moves between acquired 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 these errors and achieve centimeter-accurate positioning. NTRIP is used to provide calibration data to the sensor. This data can be obtained from publicly accessible virtual reference station (VRS) or local base station networks.

Difference between fixed position starter set and IP sensor unit The starter kit of the Swiss company Fixposition AG contains all components that are necessary at the beginning, such as GPS antennas, cable set, battery and charger etc. The IP sensor unit, on the other hand, is the heart of the system and can be used when the rest of the peripherals are already available.
