Adds GLONASS L2 C/A signal processing to GNSS-SDR based on previous
work developed for the L1 signal. All code have been added in a single
commit with the idea to illustrate the process of signal addition for
future work
Debugs code to fix GLONASS coherent integration. Adds message handling
from telemetry decoding to signal tracking modules. Bug on poor track
performance stills need to be determine.
Added code to enable RTCM header generation when in GLONASS. Also fixes
bug to allow combined observations from GPS and GLONASS. Fix some code
compilation warnings and unit tests.
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.
Signal identifier for GLONASS L1 C/A was changed internally to be `1G`
instead of the '1C' originally conceived from the navigation software.
Also, forces PRN number update from decoding interface
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
Forces conversion of semicircles to radians units in some GNAV Almanac
parameters. In addition, adds safeguards in code to avoid invalid
slot number identification.
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
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.
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
