u-blox DAN-F10N – Dual-Band (L1/L5) GNSS Module with Integrated Patch Antenna in a Compact Package

The u-blox F10 dual-band GNSS platform, launched during the previous year, combines L1 and L5 bands to improve multipath resistance and provide meter-level positioning accuracy. It is intended for urban mobility use cases like aftermarket telematics and micromobility, where reliable and precise positioning is critical.

Following this technology, u-blox has now launched the DAN-F10N patch-antenna module, using the F10 platform’s dual-band GNSS support. It includes a 20 x 20 x 8 mm Right Hand Circular Polarized (RHCP) L1/L5 patch antenna that minimizes size and maximizes performance. The large beamwidth increases installation flexibility, and an optional external antenna provides further design flexibility.

For enhanced RF performance, the DAN-F10N features a SAW-LNA-SAW design with an LTE B13 notch filter on the L1 RF path to provide improved out-of-band interference rejection. This renders the module ideal for use in devices that coexist near cellular modems, providing signal reliability in dense cityscapes.

The DAN-F10N module is compatible with u-center 2 GNSS software, allowing real-time performance analysis, receiver configuration, and data logging. It also supports AssistNow Online, AssistNow Offline, and AssistNow Autonomous A-GNSS services for faster satellite acquisition. For communication, the module uses NMEA 4.11 and UBX binary protocols, offering raw GNSS data output for advanced applications.

Previously, we covered the u-blox X20 all-band GNSS module, designed to deliver centimeter-level accuracy worldwide. It features a multi-band GNSS receiver and an L-band receiver that supports signals from L1, L2, L5, and the new L6/E6 bands. We also covered other GNSS modules, including the Septentrio mosaicTM and Skytraq PX1122R. You can check those modules as well.

At the time of writing, the company has not provided any pricing information about the DAN-F10N GNSS module. Additional information can be found on the product page and the press release.
