Abstract: | Analytic solutions for the least squares covariance and for steady state optimal estimate covariance have been derived. These solutions define and succinctly describe the relationship between clock performance, satellite geometry and system accuracy. It is seen that the clock attenuates the “bad geometry” effect associated with one-way ranging. The steady state solutions obtained depend on certain specializations of the system dynamics and on limit cases where the clock is either much better than or much worse than the position dead-reckoner. |
