wrong 1057 message?

Description

Message from Sara Gerrard:

I have been successfully downloading rtcm data, specifically message types 1057 and 1058 from your casters, but there are ways in which the messages seem inconsistent with the expected format
..
I am still, however, interested in why the header appears in the middle of the 1057 message?
..
I have just collected this small data set from products: IGS03. There are two files attached - the full data set and then one with just a 1057 message (first one that appears in full set).

The raw data format from BNC does not take care of the input stream characteristics, but only of the network connection - it does not know about RTCM blocks at this stage. This means headers can also be in the middle of a message. When analysing without BNC to get continous blocks you need to strip the headers and join the matching streams before analysing the contents.
