r5662 r5673 2361 2361 <p> A value of zero '0' tells BNC to upload all orbit correction samples coming in from the real-time GNSS engine along with the clock correction samples to produce combined orbit and clock corrections to Broadcast Ephemeris (1060 for GPS, 1066 for GLONASS). 2362 2362 </p> 2363 2363 <p> 2364 Configuration examples: 2365 </p> 2366 Let us suppose an real-time network engine supporting BNC <u>every 5 seconds</u> with GPS Broadcast Corrections for orbits, clocks and code biases in 'RTNET' stream format. 2367 <ul> 2368 <li>With 'Sampling Orb' set to '0' BNC would produce</li> 2369 <ul> 2370 <li>Every 5 seconds a 1059 message for GPS code biases,</li> 2371 <li>Every 5 seconds a 1060 message for combined orbit and clock corrections to GPS Broadcast Ephemeris.</li> 2372 </ul> 2373 <br> 2374 <li>With 'Sampling Orb' set to '5' BNC would produce</li> 2375 <ul> 2376 <li>Every 5 seconds a 1057 message for GPS orbit corrections to Broadcast Ephemeris,</li> 2377 <li>Every 5 seconds a 1058 message for GPS clock corrections to Broadcast Ephemeris,</li> 2378 <li>Every 5 seconds a 1059 message for GPS code biases.</li> 2379 </ul> 2380 <br> 2381 <li>With 'Sampling Orb' set to '10' BNC would produce</li> 2382 <ul> 2383 <li>Every 10 seconds a 1057 message for GPS orbit corrections to Broadcast Ephemeris,</li> 2384 <li>Every 5 seconds a 1058 message for GPS clock corrections to Broadcast Ephemeris,</li> 2385 <li>Every 5 seconds a 1059 message for GPS code biases.</li> 2386 </ul> 2387 </ul> 2388 Note that only when specifying a value of zereo '0' (default) for 'Sampling Orb', BNC produces <u>combined</u> orbit and clock correction messages. 2364 2389 <p><a name="upclksp3"><h4>3.14.8.2 SP3 - mandatory if 'SP3 File' is specified</h4></p> 2365 2390 <p>Select the SP3 orbit file sampling interval in minutes. A value of 15 min may be appropriate. A value of zero '0' tells BNC to store all available samples into SP3 orbit files.</p>
