MicroStrain by HBK’s PX4 Drivers Now Available in Main Repository

MicroStrain by HBK’s PX4 drivers are now officially part of the main PX4 branch, with support expanded to include the 3DM-CV7-INS and 3DM-CV7-GNSS/INS sensors.

All CV7 Series sensors, including the previously supported 3DM-CV7-AR and 3DM-CV7-AHRS, are now fully compatible with PX4. Developers and system integrators using PX4 can seamlessly incorporate any CV7 Series sensor into tactical unmanned aerial vehicles (UAVs), military robotic platforms, and autonomous defense systems.

PX4 drivers are now available in the main PX4 repository, with support for USB and UART interfaces. Compatible with ROS1, ROS2, and HBK’s SensorConnect and InertialConnect tools, the update also supports open-source APIs via MSCL and MIP SDK for custom development.

This update simplifies the integration process for developers and expands the versatility of PX4-based systems. The CV7 Series now offers broader compatibility with one of the most widely used open-source flight stacks.

CV7 Series

The CV7 Series delivers tactical-grade inertial sensing with high-speed data output, robust filtering, and compact form factors, all of which are critical for precision navigation and control.

The 3DM-CV7-INS combines inertial sensing with external GNSS inputs for complete navigation solutions, while the 3DM-CV7-GNSS/INS provides tightly coupled GNSS and inertial data for high-accuracy positioning in dynamic environments. The 3DM-CV7-AR and AHRS continue to provide high-performance orientation and heading data with adaptive filtering and magnetometer integration.
