c8f7e08127 Updated all GPS and Galileo trackings for double floating point internal 
computations and bug fixes in the carrier phase accumulator.
(all, except Matlab-Simulink linked trackings)
 2015-11-26 18:44:04 +01:00
Cillian O'Driscoll
26b18c19ee Added a generic tracking_loop_filter class 
This implements a generic loop filter. Based on the analog PLL filters
from Kaplan and Hegarty, with a bilinear (Tustin's) transform from
s-plane to z-plane ( 1/s -> T/2 ( 1 + z^-1 )/( 1 - z^-1 ) )

Also added tests. Note the "truth" outputs
were derived from an Octave implementation of the loop filter and
Octave's builtin filter function
 2015-11-26 15:12:26 +00:00
Cillian O'Driscoll
518deb501a Added IF handling to acq and tracking 
Only GPS L1 CA DLL PLL tracking for now. Still experimental.
 2015-11-26 15:12:26 +00:00
Cillian O'Driscoll
b95219dbc6 Added two Carrier_rotate correlator utilities 
1) Carrier_rotate_and_EPL_volk

This is a very efficient VOLK based carrier wipeoff and
Early/Prompt/Late correlation. The carrier wipe off is done using the
VOLK rotator functions, which means there is no need to generate a local
replica sinusoid.

2) Carrier_rotate_and_VEPL_Volk

This adds Very Early/Early/Prompt/Late/Very Late correlation with the
VOLK rotator implementation of carrier wipe-off
