Description

The Siderion Polaris F10N is an affordable, compact standard precision dual-band patch antenna module based on the u-blox F10 L1/L5 GNSS device. It provides robust meter-level positioning accuracy in challenging environments. Using u-blox DAN-F10N proprietary dual-band multipath mitigation technology, the Polaris F10N utilises the best signals from the L1/L5 bands to achieve better accuracy in urban environments. The onboard BMP581 absolute barometric pressure sensor and the professional-grade RM3100 compass enhance the overall performance of the Polaris F10N. The JST-GH connectors make them perfect to be connected to a Pixhawk or any autopilots. The Polaris F10N operates across a temperature range from -40°C to +70°C.
