d664dc63b3 Experimental extended correlation for GPS L1 CA C_Aid tracking 2016-03-08 18:30:56 +01:00
Javier Arribas
4480c12d94 Added a non CFAR PCPS acquisition algorithm based on the estimation of 
the post correlation noise floor. If enabled
(.Acquisition_1C.use_CFAR_algorithm=true) as an option in the
acquisition configuration, it allows setting more stable thresholds in
the presence of non-gaussian front-end noise (which is the usual
behavior of front-ends....)

5a716840ab tracking dll pll cAid can work now with gr_complex and cshort just 
setting the data imput type in config file. All the internal receiver
signal chain can work in complex short for the first time. Speed
improvement using custom gnss-sdr volk kernels for cshort data input
types.

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.

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)
