Subject: Codeless and Semi-Codeless Access to the Global Positioning ,System Date: Mon, 09 Jun 2008 08:56:32 -0500 From: Don Rowe To: Jason.Kim@noaa.gov Gentleman I am currently using 6 L1\L2 receivers which will be made useless for rtk by this proposal. I would ask for an additional 5 years years to 2025 to allow private firms to phase in the new receivers. I would also ask that the comment time be extended to allow more wide spread knowledge of this proposal in the industry. Thanks Don Rowe -- Donald W.
