Specify an IP port number to activate this function. The default is an empty option field, meaning that no Ephemeris Correction output via IP port is generated. 413 </p> 414 <p> 415 The source code for BNC comes with an example perl script 'test_bnc_eph.pl' that allows you to read BNC's Ephemeris Corrections from the IP port. In case of a stream carrying message types 4056 and 4057, the script produces ASCII records containing the following set of parameters: 404 <p> 405 The saved file contains the following information in plain ASCII format: 416 406 </p> 417 407 <p> … … 425 415 <li>Along-track Component of Orbit Correction to Broadcast Ephemeris [m]</li> 426 416 <li>Cross-track Component of Orbit Correction to Broadcast Ephemeris [m]</li> 427 <li>Mountpoint</li> 428 </ul> 417 </ul> 418 </p> 419 <p> 420 Example file contents: 421 </p> 422 <pre> 423 ... 424 1490 115710.0 G27 97 5.291 1.201 -1.964 0.821 425 1490 115710.0 G26 14 -11.247 1.003 -1.168 0.074 426 ... 427 </pre> 428 429 <p><a name="corrint"><h4>3.7.2 Interval - mandatory if 'Directory' is set</h4></p> 430 <p> 431 Select the length of the Ephemeris Correction files.
