SparkFun Dualband L1/L5 GNSS Breakout - DAN-F10N

SparkFun Dualband L1/L5 GNSS Breakout - DAN-F10N (GPS-28435)

The SparkFun DAN-F10N Dualband GNSS Breakout is built around the powerful u-blox F10 engine, offering simultaneous reception of L1 and L5 frequency bands. This board leverages u-blox's advanced multipath mitigation technology to isolate the strongest signals, delivering reliable, meter-level position accuracy even in dense urban canyons. To ensure signal integrity, the module incorporates a robust SAW-LNA-SAW RF front-end with an additional notch filter (LTE B13), providing excellent rejection of interference from nearby cellular modems.

The SparkFun Dualband L1/L5 GNSS Breakout - DAN-F10N features u-blox's dual-band GNSS technology for the L1/L5 frequency bands. Their proprietary dual-band multipath mitigation technology enables the u-blox F10 GNSS engine to isolate the best signals from the L1 and L5 bands; delivering a solid meter-level position accuracy in challenging urban environments. Additionally, the DAN-F10N module's robust SAW-LNA-SAW RF architecture with an additional notch filter (LTE B13) on the L1 RF path ensures the best possible out-of-band interference mitigation from nearby cellular modems.

The DAN-F10N GNSS module on this board comes with a 20 x 20 x 8 mm, integrated, Right Hand Circular Polarized (RHCP), L1/L5 dual-band patch antenna that offers the best compromise between size and performance. The patch antenna's wide beamwidth provides flexibility in the device's orientation; while alternatively, the module also has an antenna switch function to give users the option to utilize an external dual-band antenna, further increasing its utility.

The DAN-F10N module is supported by the u-blox u-center 2 GNSS software for real-time performance analysis, receiver configuration, and data logging. The AssistNow Online, Offline, and Autonomous A-GNSS services can also be used with the module for faster satellite acquisition. Users can also interface with the GNSS module using NMEA 4.11 and UBX binary protocols.

Note

The GPS L5 signals are currently, considered as "pre-operational" and not utilized by default in navigation solutions. However, it is possible override the receiver's configuration to evaluate the GPS L5 signals. Please refer to the integration manual for more details.

This is an operational limitation of the satellite/space segment and not an issue of the u-blox product.
