4.2  Changing enabled constellations 
The enabled satellite  constellations and signals are controlled by configuration items in the CFG-
SIGNAL group. A constellation is enabled when the constellation’s enable key and both the L1 and L2 
band keys are set to 1. Disabling a constellation can be done by setting the constellation’s enable key 
to 0. 
For example:  
•  To disable the BeiDou constellation, set the configuration item CFG-SIGNAL-BDS_ENA to 0. 
•  To enable the  BeiDou  constellation, set the configuration items CFG-SIGNAL-BDS_ENA, CFG-
SIGNAL-BDS_B1_ENA and CFG-SIGNAL-BDS_B2_ENA to 1.
