The SL869L-V2 and SL869L-V2S modules include a built-in LNA to increase sensitivity.
1PPS
The module provides a 1PPS output signal.
Please refer to Section 9.3.5.1 1PPS for detailed information.
Power Management Modes
The receiver supports operating modes that reduce overall current consumption with
less frequent position fixes. Availability of GNSS signals in the operating environment will
be a factor in choosing power management modes. The designer can choose a mode that
provides the best trade-off of navigation performance versus power consumption.
The various power management modes can be enabled by sending the desired command
using the host serial port (RX).
