Septentrio has taken a step towards simplifying the process of integrating its GNSS receivers, which include inertial navigation systems (GNSS/INS). Its new RxLeverArm software tool makes GNSS/INS setup easier and improves accuracy, with automatic optimization of lever arm settings.

RxLeverArm is now part of the Septentrio RxTools software package included with every Septentrio GNSS/INS receiver. This new tool automatically visualizes, validates and calibrates the exact distance between the INS sensor and the antenna, eliminating the need for precise distance measurements with complex instruments.

“We focus our design on simple, efficient and effective INS installations, ensuring short time to market and accurate deployment for our customers,” said Danilo Sabbatini, Product Manager at Septentrio.

“The RxLeverArm tool, combined with the intuitive web-based user interface, as well as the support material available in our knowledge base, allows customers to begin testing within minutes of physically installing their receiver,” said said Sabbatini.

For lever arm compensation, users only need to measure the approximate distance between the inertial measurement unit (IMU) and the main GNSS antenna reference points on the vehicle. The data is then recorded under open sky conditions, allowing the RxLeverArm tool to optimize the initial approximate distance measurement and avoid common errors such as sign inversion.

The result is a simplified installation process and improved accuracy of the lever arm measurement.
