SE868K5-DR Positioning Receiver

GNSS Module with Untethered Dead Reckoning, Dual-Frequency and Multi-constellation

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.

Form Factor Family

The SE868 family offers positioning solutions and customizations in a compact 11 x 11 mm form factor. Telit Cinterion’s integrated proprietary commands enable easy transition between variants. These unified command sets reduce development complexity without additional costs.
