Added info to GPS signals
Hi there,

Thanks for your edit. I'm going to revert it back, but wanted to touch base with you on the changes.

The information you labeled as general, or common, isn't exactly common. Pilot carriers are only being talked about specifically with the L5 signal. The L2C and M-code specifications don't list a pilot carrier. FEC might be a general feature, but it was already being discussed in context of the article.

Now, maybe the article needs more info in each section where those topics are being discussed. If so, I'd encourage you to add information that you can cite to those sections and really help them grow! - Davandron | Talk 02:38, 15 January 2008 (UTC)

RE: Added info to GPS signals
Hi Davandron,

I revised my contribution on Modernized GPS signals. I changed the language about "pilot carrier" and used "data-less acquisition aid" instead. You're right that the term "pilot carrier" is not common to all modernized civilian signals. L5 uses a "pilot carrier" as well as L1C, but not L2C. It's really the same concept on all signals (pilot carrier vs data-less acquisition aid), just the wording is different.

Also, I think it's useful to mention Forward Error Correction early. By summarizing the modernized improvements in a single place, we're orienting the reader to better comprehend the information that follows.

Let me know what you think.
