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.
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
GNSS-SDR.internal_fs_sps
The old name was misleading, since the units are samples per second and
not Hertz.
Backward compatibility is kept, so this change does not break any
existing configuration.
This commit Integrates RTKLIB positioning libraries in a universal PVT
block implementation called RTKLIB_PVT. This results in an improved
positioning accuracy and precision with a wide range of options
(including Precise Point Positioning and ionospheric/troposphreic
models).
Not all the RTKLIB features have been ported. Some of them will be
progressively added. The ported options and how to configure them have
been documented in the website, see
http://gnss-sdr.org/docs/sp-blocks/pvt/
This commit also introduces a multi-band, multi system Observables block
implementation.
Relevant architectural changes that reduce latency and makes
multi-system, multi band signal handling easier.
Redundant blocks have been deleted. Old configurations are automatically
redirected to the new blocks for Observables and PVT, so the commit does
not break any existing configuration. The user should just notice a
relevant improvement in positioning performance.
# Conflicts:
# src/core/receiver/gnss_flowgraph.cc
Added information on how to retrieve SUPL parameters, and indicators to
userd on where to point to their own file or IP address. Removed unused
parameter wait_for_flowgraph.
Old configurations folder removed. Names ending by "short" but reading
files of interleaved data have been renamed to "ishort". Some spare
fixes. Added examples of configuring the period and port of RTCM
messages.
