1.198 TRACKINGMODE (ASCII)
SF-3050 Sapphire SF-3040
This command is used to enable or disable the receiver’s tracking of various signals or
frequencies. When a GPS signal or frequency is enabled or disabled, it applies to all GPS
satellites broadcasting that signal.

Enabling a specific tracking mode is necessary to allow the receiver to acquire and
track the signal, but this alone is not sufficient. The receiver must also be licensed
for that tracking mode, and the signal must be available.
This command is typically used for engineering experiments or receiver
testing. It is not recommended for use in other applications.
Command: [TRACKINGMODE] signal1, on_off, {signal2, on_off, signal3, on_off, …, signal_N, on_off}
Parameter Definition

Multiple signals can be enabled or disabled at the same time, by repeating the pair
of signal names and the on/off keyword.

L1 cannot be turned off.
L2C requires L2. If L2 is turned off, it will force L2C off. Trying to turn L2C on when L2 is
turned off will have no effect.
G2 requires G1. If G1 is turned off, it will force G2 off. Trying to turn G2 on when G1 is
turned off will have no effect.
