Advancements in PX4 Autopilot: Dual GPS Heading Integration

ascend Engineering,a prominent player in the UAV autopilot software sector,has substantially enhanced the PX4 open-source autopilot framework by introducing a feature that allows the Holybro ZED-F9P to determine its heading using dual GPS systems for DroneCAN.

Collaboration and Growth

The initial dual heading functionality for PX4 was developed by Alex K at Ark Electronics.With the backing of Holybro, Ascend Engineering has now incorporated AP Periph support into PX4 DroneCAN, enabling the Holybro ZED-F9P to utilize dual GPS for heading determination.This enhancement broadens the applicability of PX4 across various UAV platforms, including multirotors, fixed-wing aircraft, and unmanned helicopters.

Benefits of Dual GPS Technology

Employing dual GPS sensors allows users to accurately calculate heading, especially in environments where compasses might potentially be affected by nearby metallic structures or machinery. The dual GPS configuration within the PX4 autopilot stack facilitates precise and consistent turns, a significant advantage over conventional compass systems. This makes it particularly suitable for applications in surveying and urban inspections.

Streamlined User Experience

The latest feature from Ascend Engineering integrates these advanced GPS units into the Holybro ZED-F9P DroneCAN GPS driver, ensuring a smoother setup process for users prior to testing and operation.
