Javier Arribas 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....)

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

Javier Arribas 8b2d21c1c9 Major changes:
- Gps telemetry decoder and PVT now uses independent queues for ephemeris, iono, utc_model and almanac. The old gps_navigation_queue is now deprecated and it is removed from the implementation. This affect almost all the PVT and Rinex printer classes.
- Rinex printer class updated to use the new ephemeris, iono, utc_model objects
Bug fixes and correction:
- The pseudorange generation now is based on the computed TOW for each received symbol. The History_Shift computation become simplier in this way. This modification is also a solution for a bug where the pseudoranges became temporally invalid when the TOW is updated (that happen every 6 secons!)

Javier Arribas 9d34147e0f Major update to improve the GNSS-SDR pseudorange precision and correct some PVT bugs:
- Updated all available trackings to generate the tracking_timestamp_secs taking into account the remainder code phase.
- Updated the telemetry decoder to track the number of symbol shifted from the preamble start symbol (to be used in observables).
- Updated observables to align the reference channel symbol with the corresponding symbols in the other channels and compute pseudorranges using the common transmission time algorithm.
- Updated PVT to independize the display output rate from the RINEX and KML log files. New options available in config file!
- Some minor improvements and code cleaning.
