PCTEL, www.pctel.com 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. SBG Systems, www.sbg-systems.com
