@ -30,16 +30,27 @@ The last step is optional. Without it, you still will get the executable at `../
$ obsdiff --ref_rinex_obs=reference.20o --test_rinex_obs=rover.20o
```
There is some flexibility in how flags may be specified. The following examples are equivalent:
```
$ obsdiff -ref_rinex_obs=reference.20o
$ obsdiff --ref_rinex_obs=reference.20o
$ obsdiff -ref_rinex_obs reference.20o
$ obsdiff --ref_rinex_obs reference.20o
```
Available command-line flags:
| **flag** | **Default value** | **Description** |
|:------------------------:|:-----------------:|:-----------------|
| `--skip_obs_transitory_s` | `30.0` | Skip the initial observable outputs to avoid transitory results [s]. |
| `--skip_obs_ends_s` | `5.0` | Skip the lasts observable outputs to avoid transitory results [s]. |
| `--single_diffs` | `false` | [`true`, `false`]: If `true`, the program also computes the single difference errors for [Carrier Phase](https://gnss-sdr.org/docs/sp-blocks/observables/#carrier-phase-measurement) and [Doppler](https://gnss-sdr.org/docs/sp-blocks/observables/#doppler-shift-measurement) measurements (requires LO synchronization between receivers). |
| `--compare_with_5X` | `false` | [`true`, `false`]: If `true`, the program compares the E5a Doppler and Carrier Phases with the E5 full Bw in RINEX (expect discrepancy due to the center frequencies difference). |
| `--dupli_sat` | `false` | [`true`, `false`]: If `true`, this flag enables special observable test mode where the scenario contains duplicated satellite orbits. |
| `--dupli_sat_prns` | `1,2,3,4` | List of duplicated satellites PRN pairs (_i.e._, `1,2,3,4` indicates that the PRNs 1,2 share the same orbit. The same applies for PRNs 3,4). |
| `--ref_rinex_obs` | `reference.obs` | Filename of reference RINEX observation file. |
| `--test_rinex_obs` | `test.obs` | Filename of tested RINEX observation file. |
| `--show_plots` | `true` | [`true`, `false`]: If `true`, and if [gnuplot](http://www.gnuplot.info/) is found on the system, displays results plots on screen. Please set it to `false` for non-interactive testing. |
