The problem is made worse by the fact that, at this location, the satellites are at low elevation angles most of the time. We are therefore missing almost half of the expected observations. The same receiver had previously been installed at HOLM (2002-11-26 to 2003-04-03) and experienced the same problem, although not to this extent. We have contacted Thales about the problem and hope to have a replacement receiver installed shortly. -- Mike Craymer, Ph.D. Geodetic Survey Division, Natural Resources Canada 615 Booth Street, Ottawa, Ontario K1A 0E9, Canada Tel 613-947-1829, Fax 613-992-6628, Cell 613-791-0157 Email Geodetic Survey Division NAREF
