Photo: CHC Navigation
The i90 IMU-RTK GNSS series receiver is designed to dramatically increase GNSS real-time kinematic (RTK) availability and reliability. The i90 is powered by the company’s latest inertial measurement unit (IMU) and RTK technology to provide robust and accurate GNSS positioning in any circumstances. Unlike standard micro-electro-mechanical (MEMS)-based GNSS receivers, the i90 GNSS IMU-RTK combines a high-end calibration and interference-free IMU sensor with a state-of-the-art GNSS RTK engine and advanced GNSS tracking capabilities. The i90 is designed to increase the productivity and reliability of survey projects, with no complicated calibration process, rotation, leveling or accessories are necessary. A few meters’ walk will initialize the i90 internal IMU sensor and enable RTK survey in difficult field environments. The i90 GNSS automatic pole-tilt compensation boosts survey and stakeout speed by up to 20%.

Firmware update
Includes new automotive package for Ellipse GNSS/IMU products
Photo: SBG Systems
New features have been added to the Ellipse product line with firmware update version 1.7. The update better answers needs of the autonomous testing and driving markets such as a CAN odometer. Users now have the choice to connect an external odometer (DMI) with pulses or use their car odometer with velocity information. New outputs include body velocity and slip angle, which calculate the drift angle between the vehicle’s assumed trajectory and its actual trajectory. For precision applications as well as low dynamics and reduced warm-up time, the new firmware allows users to run the Ellipse Kalman filter with no lever-arm estimation. This will ensure centimeter pass-to-pass accuracy for real-time kinematic (RTK) applications and allow operation in lower dynamics while reducing warm-up time. The firmware update also provides new features for advanced marine applications.
