Hughes / Raytheon
Looks like hughes aircraft became raytheon

HISTORY OF THE CONTRACT

In August 1995, FAA awarded a cost-plus fixed fee contract to Wilcox Electric to deliver WAAS. The contract was estimated to cost $475 million. Shortly after awarding the contract, FAA began to have concerns about Wilcox's ability to provide sufficient information on exactly when WAAS could be delivered and how much it would cost. In April 1996, FAA determined that Wilcox could not meet its contractual requirements and terminated the contract.

In May 1996, FAA entered into an interim contract with Hughes Aircraft, which had been a primary subcontractor under Wilcox. The interim contract with Hughes was subsequently expanded and finalized in October 1996. In January 1998, Hughes Aircraft merged with Raytheon Systems Company (now part of Raytheon Corporation).

Raytheon still in the picture?

MARLBORO, Mass., Nov. 1, 2004 /PRNewswire-FirstCall/ -- The Federal Aviation Administration and Raytheon Company (NYSE: RTN) have completed negotiations on a contract modification for the Wide Area Augmentation System (WAAS) to deploy what is termed "Full Lateral Precision with Vertical Guidance (LPV) Performance."

Comments
I haven't looked too closely at the tech details, but my first thoughts are that the accuracy thing is rehashed in several articles, maybe a template could be used or a separate article, so all the gps articles could link to the same one and they would all be the same instead of the DGPS, GPS and WAAS articles all saying something different. Also, WP:MOSDATE indicates that Month Year shouldn't be wikilinked. There is still a bunch of uncited stuff in the article, I think the History and Development section has a single citation for several paragraphs. Overall, the layout seems better, but the timeline and accuracy tables seem large for a non-list article. I know the timeline is in the current article, but when re-writing it could re-evaluated. I believe that the WP:MOS favors prose to lists and tables. Thanks for taking the time to rewrite. --Dual Freq 14:33, 23 November 2006 (UTC)


 * I personally like the timeline as a table, but suggest it be reversed so that it's chronological (oldest event to newest). It's hard to follow what's happening, otherwise.  (Most recent event at the top of a table is most useful for things like programming and status reports on active projects, but this really is a history - in the making, true - article, and history is best told - I think - as a beginning to end story.)

 * Maybe a less obtrusive way would be similar to what I did with Strategic Defense Initiative using Template:SDIO timeline. It's self hiding and a template, maybe useful, maybe not. --Dual Freq 16:23, 23 November 2006 (UTC)


 * Thank you to both of you. My thoughts followed yours regarding the accuracy; I originally had a note to myself questioning its value to the article. If I remove it, I think some people will complain / restore it. I like the idea of a template. I'll work on that.
 * As for the dates, that was my misunderstanding; I'll fix it.
 * There is a LOT of stuff to be cited, but here are actually many sources for information. There is hidden text in my article for me to come back and correctly cite.
 * Regarding the timeline, I like that self hiding timeline! Its also prettier. I'm going to implement it here. Thanks again! Davandron | Talk 15:09, 27 November 2006 (UTC)

History to integrate
Original name may have been FAA Wide Area Differential GPS (WADGPS) also
 * 
 * The FAA is considering three types of differential GPS service for aviation use: (1) local area DGPS (LADGPS), which would be located at each airport or closely grouped airports to support instrument approaches to current CAT I weather minimums; (2) wide area DGPS (WADGPS), which would provide GPS integrity broadcast (GIB) and accuracy improvements for all of North America; and (3) use of kinematic carrier phase positioning for instrument approach and landing.
