SE868K5-DR Positioning Receiver

GNSS Module with Untethered Dead Reckoning, Dual-Frequency and Multiconstellation

The SE868K5-DR is a dual-frequency and multiconstellation positioning receiver. It adds an external inertial measurement unit (IMU) to integrate dead reckoning capabilities and features:

  • A powerful baseband processor
  • Embedded memory and PSRAM
  • Integrated PGA for optimal performance

Product Description

The SE868K5-DR GNSS module is a member of the xE868 series. It uses two frequencies (i.e., L1/E1 and L5/E5) to enhance location accuracy and reduce multipath effects in urban areas. This receiver provides reliable performance and relays continuous positioning information even when the satellite signal is unavailable.
