First positon fix using a combination of GLONASS and GPS data in
GNSS-SDR. The position solution may need further testing but initial
results are looking quite promising.
First GLONASS L1 C/A position fix using GNSS-SDR. Fixes bug in toe
reporting for GLONASS and cleans up the code a bit. Small bug with
RINEX file still present but achievement deserves its own commit.
Need to fix bug in time duration with posix time and deal with day
offsets in the code. Something seems off with day duration for long
periods of time.
Adds settings in rtklib code to parse GLONASS measurements in `obs_t`
and 'nav_t' structures. It also adds the time of day field in gnav eph
to keep track as of when ephemeris are reported.
Fixes bug in TOW update when a new value has been computed. This adds a
new flag to keep track of TOW update given the tk component. The code
fix improves the pseudorange measurement for code
Fixes the TOW computation mapping from GLONASS Time to UTC time and then
conversion to TOW and WN. The logic of the conversion considers time
offsets but may need to be reviewed.
Forces conversion of semicircles to radians units in some GNAV Almanac
parameters. In addition, adds safeguards in code to avoid invalid
slot number identification.
Removes the satellite position computation from the GNAV Almanac object
since it does not seems to be a great usage at the moment. Possible
addition of the fields should be added to the RTKLib API
Adds code to update the almanac information for satellites when decoded
by reducing the flags for the update. Almanac update is now reported
when the 2 required strings are decoded.
Adds conversion from relative code to data bits while decoding GLONASS
GNAV data. It also fixes bugs with CRC computation and extraction of
data from navigation message

GNAV data. It also fixes bugs with CRC computation and extraction of

Adds code to solve the shared frequency channels for GLONASS satellites
during acq and trk, it is now decode responsability to fix the identifier
when decoding of ephemeris happens. It also adds more details in tracking
plotting and fixes silly bug that created false alarm.
The code fixes the computation of the carrier frequency for pcps
acquisition of GLONASS satellites by making it relative to the IF. Also
new plotting features are added to visualize results
Adds tracking results plot for GLONASS processing following code for
GPS. Also fix a couple of bugs in the code and address bugs from
acq and trk modules
Starts merging process of the acquisition and tracking code for GLONASS
processing developed by Gabriel Araujo. Fixes compile warnings and
errors introduced during rebase operation
Fixes GLONASS L1 CA telemetry decoder and creating connections with
observables blocks before PVT computation. Fixes documentation and code
style in the block
Adding unit test for system-parameters block, testing string decoding
logic for GLONASS GNAV messages. Bug fixes the code after several errors
were detected while debugging
Fixes compilation errors after the RTCM package addition in the PVT
block. It also adds a series of class members documentation in the code
using the Doxygen standard while fixing code style errors
Adds set of unit test to check functionality of GLONASS processing for
RINEX and RTCM messages. It also fixes a couple of bug fixes with
formatting in existing code.
Adds code for RTCM in GLONASS processing. The commit includes legacy
messages (MS1009-MS1012) and integrated messages for GNSS fields.
A couple of bug fixes are included and addition of ephemeris fields
is completed.
