885c5f364c Small bug fix and new configuration file ready to receive GPS signals in real-time with USRP devices and appropiate front-ends. Remember to tune the front-end gain (source section in config file) and, in some particular antenna and LNA setups, tune also the acquisition threshold (acquisition section). The configuration is tested on USRP v1 + DBSRX, USRP 2 + DBSRX and USRP B100 + WBX.

e728450192 New feature (FE01): RINEX v 2.11 now outputs the following observables: 
PSEUDORANGE
CARRIER PHASE
CARRIER DOPPLER
SIGNAL STRENGTH (dB-Hz)

thus, it enables the realtime kinematics and PPP positioning for first time in an open source GNSS SDR. Enjoy!

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.
