0362476864 Merging gnss-sdr/rinex_fix branch 
This commit rewrites the way pseudoranges are computed, now accounting for the receiver clock offset. It also adds more work in the QA code. If extra tests are activated by -DENABLE_UNIT_TESTING_EXTRA=ON or -DENABLE_SYSTEM_TESTING_EXTRA=ON, additional raw data files, a software-defined signal generator and GPSTk 2.9 are downloaded. Many fixes and code refactoring in tracking blocks.

 2016-09-19 01:32:30 +02:00
Cillian O'Driscoll
8d8249247f Alternative fix for issue #31 
Rather than changing the index type to uint16_t, I think it would be
better to use the volk_32f_index_max32* functions instead of the 16 bit
counterparts. This ensures backwards compatibility (the index was
previously 32 bit, even if the function name indicated that it was 16
bit) and also, for FFT acquisition we may encounter large FFTs with more
than 65 535 points

5a73b4e047 Improve package reproducibility 
Packages using CMake often use file(GLOB ...) to retrieve a list of
source files. As this is based on readdir(), the resulting file list
is unsorted. A common use case is to pass this list directly to
add_executable or add_library. But as the order is unpredictable, the
binaries are not reproducible (because the order in which the objects
are linked will vary).

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

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

This is a generic gnuradio block for handling 2 bit samples packed into

samples within the byte, as well as big or little endian ordering of the
bytes within a short.

This is a utility function for a generic sample source which will be
able to handle all of these cases for both real and complex signals.
