As data coverage and quality, and global models derived from satellite orbit analysis become more accurate, regional geoid solutions should be upgraded. This paper describes the upgrade of our “UNB Dec. ’86” solution for Canada carried out under a contractual arrangement with the Federal Government of Canada.
