38e8feefa8 Name change in new DLL PLL algorithm implementation. We introduce DLL
PLL Carrier Aided Tracking.
2015-11-27 12:53:27 +01:00

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)

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

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

072d0cad67 Important bug found and fixed:
Volk memory alignement for signal vectors was using a hardcoded 16 bytes
value. This parameter is machine-dependant and thus, in modern machines
caused memory exceptions if the parameter not match.

All posix_memalign functions are now replaced by the GNU Radio
volk_malloc(vector_size (bytes), volk_get_alignement());

volk_get_alignement() returns the number of bytes to align the memory
blocks in the current processor.

The memory bug showed up when the receiver is configured with higher
sample rates (>4 Msps!)

b0d33328d5 Simultaneous multi-GNSS system acquisition, tracking and telemetry

The changes in the configuration file parameter names are NOT backward
compatible. The receiver can still work as usual in single GNSS system
mode but some modification on configuration files are required. Use the
example provided of Hybrid configuration file.
