I'm looking to update the ASN.1 definitions of the SULP, LPP, and RRLP from their respective specifications. However I was wondering if anybody knew of a better source for ASN.1 definitions than the protocol specifications themselves? Copying and pasting from PDF files would be rather tedious.

Unfortunately, I am not aware of a source for these ASN.1 modules in text format. You can, however copy all of the text from the PDF into a Word file in .doc (not .docx) format, and can then use the OSS ASN.1 Studio (available from link:OSS Nokalva) to import the ASN.1 modules from the Word file. This will likely be much easier than going through and trying to copy/paste each of the ASN.1 modules yourself.

Unfortunately, ETSI and 3GPP do not seem to provide an equivalent of the ITU-T ASN.1 Module Database where you can find all of the ASN.1 modules from ITU-T Recommendations.

Can the platform vendor provide them for you? I don't know of a centralized source for ASN.1 definition files in text form, though to save you some typing I would think the platform vendor should be able to provide this. I've also been able to google some ASN.1 decoders in the past which also included the text definition files for some of the major vendors (Nokia, Ericsson), though I don't remember ever finding any for the mobile positioning platforms (CDRs mostly).
