SE868SY-SF

Multiconstellation Positioning GNSS

The SE868SY-SF is the single band variant of the well-known SE868SY-D. The GNSS receiver supports GPS, Galileo, GLONASS and BeiDou in the L1 band as well as QZSS and SBAS. The SE868SY-SF can navigate to -161 dBm and track to -165 dBm, providing improved performance in harsh environments. It is pin-out compatible with the SE868 V3 as well as the JF2 and the SE868 V2. It can track GPS, Galileo, GLONASS or BeiDou constellations simultaneously, providing the host device with high-value benefits from multiconstellation navigation.

  • Same form factor as JF2 and SE868 V3
  • Full GNSS compliance: GPS, GLONASS, Galileo, BeiDou
  • Up to four constellations for improved performance
  • Ultralow power consumption
  • Embedded LNA allows use of passive antennas

Product Brief

Product Description

The SE868SY-SF is encased in an 11 x 11 mm QFN-like package. It includes a powerful baseband processor, embedded flash memory and integrated LNA. Its ultra-sensitive RF front-end and multiconstellation capability enable high-quality navigation in outdoor scenarios and in urban areas. The SE868SY-SF delivers navigation data over a serial interface according to the NMEA protocol standard. Its low power processing core delivers optimized multiconstellation tracking with ultralow power consumption.

The SE868SY-SF supports ephemeris file injection (A-GNSS) as well as satellite-based augmentation system (SBAS) to increase position accuracy and improve time to first fix (TTFF). Its onboard software engine can predict local short-term ephemeris starting from ephemeris data broadcast by GNSS satellites received by the module and stored in the internal Flash memory.

Form Factor Family

The SE868 sub-compact form factor is a well established industry standard in a 11 x 11mm, 32-pad QFN-like package. Models in the family vary in depth dimension from 2.6 to 6.1 mm depending on presence and type of integrated antenna.
