The Xsens Vision Navigator (Image: Movella)
GNSS inertial navigation
Integrates position inputs from three high-accuracy sources
The Xsens Vision Navigator integrates position inputs from three high-accuracy sources including dual-antenna real-time kinematic (RTK) GNSS receivers; an inertial measurement unit (IMU) incorporating a three-axis accelerometer, a gyroscope and magnetometer; and a visual inertial odometry system. It can optionally accept input from an external wheel-speed sensor. The positioning sensor achieves centimeter-level accuracy when operating in GNSS mode with an RTK fix. When GNSS signals are not available, the product alone achieves accuracy of 2% of travel distance, or 0.75% when supplemented by wheel speed. Xsens Vision Navigator is suitable for outdoor positioning applications such as material handling equipment, commercial and specialist vehicles, last-mile delivery, inspection equipment and UAVs, agricultural equipment, mining equipment and utility robots.

SILC Eyeonic Vision System (Image: SiLC)
Coherent Vision Solution
Delivers high levels of vision perception
The Eyeonic Vision System is a frequency-modulated continuous wave lidar solution, which delivers high levels of vision perception to identify and avoid objects with low latency. At the core of the Eyeonic Vision System is a fully integrated silicon photonics chip. It provides more definition and precision than legacy lidar solutions, with roughly 10 milli-degree of angular resolution coupled with millimeter-level precision. These features enable this solution to measure the shape and distance of objects with high-precision and at a large distance. The system combines the Eyeonic Vision Sensor and a digital processing solution based on a powerful field-programmable gate array. The flexible architecture enables synchronization of multiple vision sensors for unlimited points per second.

The SYN4778 (Image: Synaptics)
Integrated Circuit
Designed for the internet of things
The SYN4778 is a small, low-power GNSS integrated circuit designed to extend battery life, reduce product size, and enhance performance of advanced location-based services for internet of things (IoT) devices — wearables, mobile accessories, asset trackers, UAVS and transportation devices. It includes advanced multipath interference mitigation using L5-band signals from GPS, Galileo, BeiDou, NAVIC, SBAS and QZSS. The chip also uses the L1 satellite band to reduce both the time to first fix, and the power consumed, improving the end-user experience and enabling product developers to add additional functionality and features to their IoT devices.

SafePilot P3 (Image: Trelleborg)
Maritime Systems
Provides data on vessel positioning
The SafePilot P3 navigation system provides real-time data on vessel positioning and movement in tight waterways. It uses motion sensors and two GNSS antennas to measure the position and heading of vessels in three dimensions, minimizing time and difficulty associated with piloting procedures. SafePilot P3 has a backup battery to maintain functionality in the event of a power outage. This navigation system improves situational awareness while navigating waterways and ports globally, and also enhances communication between the captain, pilot, tug operators and canal personnel while vessels are transiting a canal and approaching a port.
