Remote command:
[:SOURce<hw>]:BB:GNPR:SATellite<st>:MODulation?
on page 73
Navigation...
Accesses the dialog for configuring the parameters of the navigation message.
Chapter 4.5, "Navigation Message Configuration" , on page 37
Modulation Control
Accesses the Chapter 4.4.4, "Modulation Control" , on page 32 dialog for enabling /
disabling particular signal components.
Signal Dynamics
Accesses the Chapter 4.4.5, "Signal Dynamics" , on page 34 dialog for configuring
Doppler signal profiles.
Initial Code Phase
(enabled only in "Static" mode and for arbitrary navigation data source)
Sets the initial code phase.
Remote command:
[:SOURce<hw>]:BB:GNPR:SATellite<st>:CPHase
on page 73
Pseudorange
Displays the propagation delay from satellite to receiver in meters that is calculated as
follows:
Pseudorange = Time Shift * c / Standard Chip Rate
, where
c
is the
speed of light.
Remote command:
[:SOURce<hw>]:BB:GNPR:SATellite<st>:PRANge
on page 74
Time Shift/ chips
Displays the propagation delay from satellite to receiver. The time shift is displayed in
chips.
Remote command:
[:SOURce<hw>]:BB:GNPR:SATellite<st>:TSHift
on page 75
Initial Doppler Shift
Displays the initial Doppler shift, at the beginning of the simulation .
The value is set with the corresponding parameter in the Signal Dynamics dialog.
The instrument calculates also the variations in the chip rate of the code. Current val-
ues of the Doppler shifted carrier frequency and chip rate are displayed as:
●
Resulting Start Frequency
●
Resulting Start Chip Rate
Remote command:
[:SOURce<hw>]:BB:GNPR:SATellite<st>:DSHift
on page 72
Initial Carrier Phase
Displays the initial carrier phase.
