RINEX Observations</h4></p> 304 304 <p> 305 Observations will be converted to RINEX if they come in either RTCM Version 2.x, RTCM Version 3.x, or RTIGS format. BNC's RINEX Observation files generally contain C1, C2, P1, P2, L1, L2, S1,and S2 observations. In case an observation is unavailable, its value is set to zero '0.000'. Note that the 'RINEX TYPE' field in the RINEX Observation file header is always set to 'M(MIXED)' even if the file does not contain any GLONASS or SABAS data.305 Observations will be converted to RINEX if they come in either RTCM Version 2.x, RTCM Version 3.x, or RTIGS format.

Galileo is not yet supported. 1535 </li> 1536 <li> 1537 BNC currently will only handle C1, C2, P1, P2, L1, L2, S1, and S2 observations as well as the cumulative loss of continuity and lock time indicators. Which observables and indicators are available on a particular stream will depend on the setup of source receiver and the data format used. RTCM Version 2.x streams do not carry signal-to-noise ratio 'S' values while RTCM Version 3.x streams can only transport one code observable per frequency. Note that signal-to-noise ratios 'S' are also logged mapped to integer numbers 1 to 9. 1534 Currently BNC only handles GPS, SBAS, GLONASS and Galileo data. 1535 </li> 1536 <li>BNC currently will only handle the following observation types:<br> 1537 For GPS satellites, 'G': C1C L1C D1C S1C C1W L1W D1W S1W C2P L2P D2P S2P C2X L2X D2X S2X C5 L5 D5 S5<br> 1538 For GLONASS satellites, 'R': C1C L1C D1C S1C C1P L1P D1P S1P C2P L2P D2P S2P C2C L2C D2C S2C<br> 1539 For Geostationary signal payloads, 'S': C1C L1C D1C S1C C1W L1W D1W S1W<br> 1540 For Galileo satellites, 'E': C1 L1 D1 S1 C5 L5 D5 S5<br> 1541 Which observables and indicators are available on a particular stream will depend on the setup of source receiver and the data format used.
