Sylphase SDGPS
The software-defined GPS(/GNSS) toolkit
|
Type signature: (cooked->cooked2)
Usage:
tracker-only [OPTION]...
Description:
The tracker
node contains the GNSS signal tracking loops.
A given signal tracking loop generates code phase and Doppler error signals that get fed back to the correlator, which keeps it centered on the peak of the autocorrelation function of the tracked signal.
Allowed options:
Option | Description |
---|---|
--help | produce help message |
--verbose-align | output extra debugging information for bit alignment |
--plot | plot live correlation waveforms |
--plot-all | plot live correlation waveforms (including from SVs which are not yet aligned) |
--plot-first | only plot first correlation waveform (useful for debugging acquisition) |
--min-sample-period arg (=0) | minimum width between plot points in seconds; plot points closer than this will be averaged |
--x-axis-unit arg (=sec) | unit of X axis (options: sec, min, hour, day) |
--x-axis-absolute | plot absolute stream time on X axis instead of relative to now (implied by --wait) |
--detrend | <no effect> |
--wait | wait for pipeline to terminate, then plot (default: live plotting) |
--live-history arg (=60) | duration of live history buffer in seconds |
--title-suffix arg | append string to plot titles |
--disable-side-peak-mitigation | disable automatic detection and correction of being locked onto side-peak of BOC correlation function |
--cn0-drop-threshold arg (=20) | drop signals with C/N_0 below this value (units: dB-Hz) |
--cn0-drop-grace-period arg (=3) | inhibit dropping signals with low C/N_0 for this long after start of tracking (units: seconds) |
