  19. Maritime DGPS Recap Upgraded Receivers & Antennas: L1/L2 (L2C) Geodetic Grade Accuracy is typically 1-3 meters (10 meters published) Much better accuracy has been observed from prototype recap sites. Testing is in progress to determine typical accuracy measurements. New system architecture is easier and less expensive to upgrade as new technologies become available. 22 Slide 22
