Not to beat a dead horse, but this discussion reminded me of something I read in the documentation that came with my E-04. I dug this up from one of the PDFs:
How does the ACK E-04 handle the GPS data input?
The E-04 receives the data input from your GPS at the same rate your GPS outputs the data. (Typically once per second) The ELT uses the last data received from your GPS as its location when the ELT is activated either manually or by the crash sensor.
