Multi-Constellation, Multi-Frequency Positioning GNSS

The SE868K5-D is a multifrequency and multiconstellation positioning receiver module and a member of the xE868 Telit Cinterion form factor family. Using two frequencies (i.e., L1/E1 and L5/E5) enhances location accuracy and reduces multipath effects in urban areas. This module can navigate down to -165 dBm and proved optimal performance in harsh environments. It improves position reporting and navigation solution performance by combining:

• GPS/QZSS and Galileo in the L1/E1 and L5/E5 bands
• GLONASS in the L1 band
• BeiDou in the B1 and B2 bands
• satellite-based augmentation systems (SBAS)

Product Features:

• 32-pad QFN-like package
• Frequency bands: GPS/QZSS L1 + L5, Galileo E1 + E5, GLONASS L1, BeiDou B1 + B2
• 75 (L1-band) / 60 (L5-band) tracking channels
• Standards: NMEA/RTCM
• Jamming rejection
• Low power modes
