| Abstract: | Principle, function and construction of the PBT-1 biaxial tilting table for calibrating accelerometers are described in this paper. Based on a constant value of gravitational acceleration at a given location of the earth and accurate measurement of tilting angle of the table, a calibrating method and procedure for primary parameters of accelerometers, i.e. sensitivity, linearity and cross axis sensitivity, are presented. |
