69e6816392
Make coexistence of different instances of gnss-sdr in the same machine easier 
If the user forgot to set parameter PVT.rtcm_output_file_enabled to false in the configuration file, this raised up the RTCM server even if flag_rtcm_server was set to false, thus preventing the execution of more than one instance of gnss-sdr in the same machine. By setting the default value of rtcm_output_file_enabled to false, just letting the PVT.flag_rtcm_server parameter to get its default value, which is false, enables more than one instance in the same host machine. This also alleviates by default optional processing load in embedded devices

Stop the Labsat_Signal_Source when the end of file is reached. This allows to use this source for automated testing. 
Now the block also accepts directly *.ls2 names in filename parameter

Remove samples parameter, it was not used. This source reads the full file(s).

Make labsat23_source constructor private, so only the smart pointer wrapper can be called

19184da0f9 The FPGA multicorrelator interrupt is enabled only once when a satellite is assigned to a particular channel. Until now the interrupt was automatically disabled by the interrupt handler of the uio driver and the multicorrelator code had to re-enable it every time. This change saves CUP cycles for real-time operation. It requires that the code that disables the interrupt in the uio driver interrupt handler is commented out. 2019-04-09 16:03:31 +02:00

2bae20d2fd Merge branch 'next' of https://github.com/gnss-sdr/gnss-sdr into fpga 
added second acquisition to reduce the time between acquisition and tracking when using the FPGA
moved the process of writing of the tracking local code to the HW accelerator from the start_tracking() function to the set_gnss_synchro() function (this is only applicable for the FPGA case)
there was a bug in the computation of the tracking starting position for the L1/E1 band when using the FPGA, only high sample counter values (>31 bits) were affected, due to a uint64_t*float mult.
