SE868SY-SF

Multi-Constellation, Multi-Frequency 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 multi-constellation navigation.

  • Same Form Factor as JF2 and SE868 V3
  • Full GNSS compliance: GPS, GLONASS, Galileo, BeiDou
  • Up to four constellations for improved performances
  • Ultra-low power consumption
  • Embedded LNA allows use of passive antennas

Product Description

The SE868SY-SF is encased in an 11 x 11 mm QFN package, includes a powerful baseband processor, embedded Flash memory and integrated LNA. Its ultra-sensitive RF front-end and multi constellation 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 protocolstandard. Its low power processing core delivers optimized multi-constellation tracking with ultra low 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 package. Models in the family vary in depth dimension from 2.6 to 6.1 mm depending on presence and type of integrated antenna.
