PRODUCT DESCRIPTION
The SL871 family of GNSS receiver modules provides complete position, velocity, and
time (PVT) engines featuring high performance, high sensitivity, and low power
consumption.
All modules compute a navigation solution using GPS signals. Multi-constellation
modules add GLONASS, BeiDou, and Galileo signals to yield better coverage, greater
accuracy, and improved availability.
Multi-constellation (MT3333-based): SL871 and SL871L
GPS only (MT3337E-based): SL871-S and SL871L-S.
