Septentrio simplifies and speeds up GNSS/INS integration
Septentrio has taken a step towards simplifying the integration process of its inertial GNSS receivers. The RxLeverArm software tool has been released to aid GNSS/INS installation and improve accuracy, with automatic optimization of lever-arm settings. RxLeverArm is now part of the RxTools software package, which is included with every Septentrio GNSS/INS receiver. This new tool visualizes, validates and automatically calibrates the exact distance between the INS sensor and the antenna, removing the need for accurate distance measurements with complex instruments.
“We are focusing our design around easy, efficient and effective INS installations ensuring short time-to-market and accurate deployment for our customers,” commented Danilo Sabbatini, Product Manager at Septentrio.
“The RxLeverArm tool in combination with the intuitive Web User Interface, as well as the support material available in our Knowledge Base, enables customers to start testing within minutes after the physical installation of their receiver.”
For lever arm compensation, users now only need to measure the rough distance between the IMU (Inertial Measurement Unit) and the main GNSS antenna reference points on the vehicle. Data is then logged under open-sky conditions, which allows RxLeverArm tool to optimize the initial rough distance measurement and prevent common errors such as sign inversion. The result is simplification of the installation process and better accuracy of the lever arm measurement.
For example, the AsteRx SBi3 Pro+ GNSS/INS multi-frequency receiver delivers reliable centimeter level positioning together with 3D orientation in challenging environments. Thanks to the built-in inertial sensor, it provides orientation (heading, pitch and roll) as well as dead reckoning, making it ideal for systems that require positioning under any condition. This housed high-performance GNSS/INS system is ideal for rapid integration into machine control or ground robotic applications. AsteRx SBi3 Pro+ is the most flexible boxed GNSS/INS solution, offering full access to raw GNSS and INS data as well as allowing multiple antenna configurations.
