The development of quadrature-based filters for orbit determination and challenges associated with their implementations while using constrained regularized variables in astrodynamics are discussed. Since the regularization process introduces redundant coordinates, a quadrature based method to explicitly account for the state constraints is developed. In particular, a non-product quadrature method known as the Conjugate Unscented Transformation is used for filter development. Numerical experiments are conducted to validate the developed filter and results are compared with linear error theory based filter such as the constrained Kalman filter.
