Near as I can tell without digging out the spec it looks correct.

You have the '=', a symbol table character, four lats, four longs, a
symbol of '_' (weather), then 3 bytes at the end of the compressed
position (didn't look to see if those are course/speed or something
else, but three bytes there is correct).  After that comes the
weather stuff and it looks correct to me.

If you bring in the track data from findu for that station does it
decode correctly in Xastir?
