Carles Fernandez cc3de3132d change input signal type from short to ishort 
So the file length in seconds is correctly displayed
 2015-12-26 13:08:12 +01:00
Carles Fernandez 286ee3b561 Integrating the RTCM printer 
Now the Galileo E1 receiver generates RTCM messages 1045 (ephemeris) and
MSM7 / 1097 (observables). Parameters related to RTCM included in conf
files. The TCP/IP server can be activated by setting flag_rtcm_server to
true.

Javier Arribas 9acc7e7a20 Replaced fix point NCO by VOLK phase rotator in CPU multicorrelator 
(around 5% faster).
This optimization is enabled at this time only in
Tracking_DLL_PLL_C_Aid. Sample config can be found in
gnss-sdr_Hybrid_byte_sim.conf

Javier Arribas 2039e998ff Pinned memory (Zero copy) huge improvement for GPU tracking. 2015-10-15 19:09:09 +02:00
Cillian O'Driscoll 19fad75a80 Added NSR conf file as e.g. use of two bit packed 
file sample source. NOTE: This has not been tested with a real NSR front
end. The assumption is, based on reading the NSRFileSignalSource, that
the data is:
 o byte item type
 o real
 o bytes are little endian (least significant bits output first)
