"A team of German researchers appears to have cracked
the GMR-1 and GMR-2 encryption algorithms [...]"

I can't find anything about GMR on Wikipedia, except
for this:

http://en.wikipedia.org/wiki/GMR_%28cryptography%29

I don't think these are the same thing.

Any pointers?

"GEO-Mobile Radio Interface Specifications". Basically these are
standards for satellite phones, roughly analogous to GSM (and much of
GMR is derived from GSM). Much of the spec is available at:

The stub article at Wikipedia has more links:

The encryption algorithm (apparently a stream cipher, and apparently
the bit that's been broken) in either version is proprietary and not
one of the publically available bits.
