Examples:
ASSIGN 0 ACTIVE 37 0 2000
ASSIGN 15 120 -250 0
ASSIGN 11 28 -250 0
The first example sets the first SV channel to acquire satellite PRN 37 in a range from -2000 Hz to +2000 Hz
until the satellite signal has been detected. SV channel 11 is set to acquire satellite PRN 28 at an offset of
-250 Hz only in the third example.

Valid Values
SV channel number to apply the command
to. 0 is the first SV channel and 31 is the last:
24GALILEO8GPS: 0-7 for GPSL1
See also Section 5.3.4, CHANCONFIG
starting on Page 53 and Table 55 on
Page 122.
Optional desired SV channel state. If a value
is not given, the default of ACTIVE is used.
Optional satellite PRN code. A value is
required only when the state field is set to
ACTIVE.
Optional current Doppler offset of the
satellite specified in the prn field in Hz.
NOTE:Satellite motion, receiver antenna
motion, and receiver clock frequency error
must be included in the calculation of
Doppler frequency.
Error or uncertainty in the Doppler estimate
given in the doppler field, in Hz.
NOTE:This is a ± value. For example, enter
500 for ± 500 Hz.

Set the SV channel to not track any satellites.
Set the SV channel active.
Tell the receiver to automatically assign PRN codes to channels.
