    53 BNC allows to by-pass its decoding and conversion algorithms, leave whatever is received untouched and save it in files. Although BNC is a real-time tool, it can be run offline for post processing of data made availabe from a file.

     58Although BNC is a real-time tool to be operated in online mode, it can be run offline for post processing of data made availabe from a file. Furthermore, besides its regular window mode, BNC can be started as a batch/background job in a 'no window' mode using processing options from previously saved configuration parameters.

    59 <li>requires access to the Internet with a minimum of about 2 to 6 kbits/sec per stream depending on the stream format and the number of visible satellites. You need to make sure that the connection can sustain the required bandwidth.<li>

    6065<li>requires the clock of the host computer to be properly synchronized.</li>
    6166<li>has the capacity to retrieve hundreds of GNSS data streams simultaneously. Please be aware that such usage may incur a heavy load on the NTRIP broadcaster side depending on the number of streams requested. We recommend limiting the number of streams where possible to avoid unnecessary workload.</li>
