    DGPS to be improved sustantially.
    From: Tony S
    Date: 2000 May 02, 18:07 EDT

    "Nationwide DGPS: The Department of Transportation is currently fielding the Nationwide Differential
    GPS
    (NDGPS) network to improve the accuracy and integrity of GPS for surface and maritime users across
    the
    United States to the 1-3 meter range. In addition, 34 countries around the world have already
    installed DGPS
    radiobeacon networks, and more are considering the adoption of this navigation standard. The
    improvement of
    the basic GPS signal through elimination of SA may allow the NDGPS radio beacons to transmit fewer
    error
    corrections and more value-added navigation messages, improving highway, railroad, and waterway
    safety. The
    range of individual NDGPS stations is also expected to increase, benefiting mariners farther off
    shore and
    opening the possibility of reducing the overall number of stations to be fielded. This flexibility
    allows for a more
    cost effective network for the government and the nation. In addition, the complexity of all DGPS
    systems will
    be reduced, lowering costs for those who will be using this technology."
