Parameters:
<Atschips> float
Range: 0 to 10.0e6
Increment: 0.001
*RST: 0.0
Example:
BB:GPS:SAT1:VID 4
sets space vehicle 4 for the first satellite.
BB:GPS:SAT2:VID 4
sets space vehicle 4 for the second satellite.
BB:GPS:SAT1:ATSC 10000
sets the additional time shift of satellite 1 to 10000
BB:GPS:SAT2:ATSC 20000
sets the additional time shift of satellite 2 to 20000
[:SOURce<hw>]:BB:GPS:SATellite<st>:CACRate?
Queries the currently valid values for the chip rate of the C/A code. The chip rate depends
on the set Doppler shift.
Suffix:

Return values:
<Cacrate> float
Example:
BB:GPS:SAT1:CACR?
queries the resulting C/A chip rate of satellite 1.
Response: 1023022.077
the chip rate is 1. 023022 08 MHz.
Usage: Query only
[:SOURce<hw>]:BB:GPS:SATellite<st>:FREQuency?
Queries the currently valid value for the doppler-shifted carrier frequency.
Suffix:

1 .. 4
Return values:
<Frequency> float
Example:
BB:GPS:SAT1:FREQ?
queries the resulting carrier frequency of satellite 1.
Response: 1575421111
the resulting carrier frequency is 1.575421111 GHz.
