The use of Doppler radar measurements to provide velocity damping for an aircraft inertial navigation system is considered. Three different Doppler antenna configurations are examined: two-axis stabilized, azimuth stabilized, and data stabilized ante

The error equations for a space-stable inertial navigation system are derived. This is done by directly perturbing the mechanization equations in the inertial frame and then transforming in open-loop fashion to the local-level frame. A rotating inert

In general, vertical deflections are obtained either by astrogeodetic methods or by gravimetric methods. In the latter approach, gravity anomaly measurements are processed by using the so-called Vening Meinesz equations to yield the vertical deflecti

Present gravimetric algorithms that approximate the Vening Meinesz equations do not take into account in any detailed way the random nature of the anomalies, deflections, and gravimeter errors. A new algorithm based on the criterion of minimizing the

In order to stabilize the altitude calculation in an inertial navigation system, an altimeter is commonly used. In a conventional local-level mechanization, this is generally accomplished by correcting the vertical channel integrators with the differ

A comparison of the error propagation in a local-level reference frame is derived for two inertial navigation systems; one has a local-level configuration, and the other has a space-stable configuration. The error propagation is shown to be equivalen

Vertical deflections and ocean currents introduce errors into ship's inertial navigation systems (SINS). In the absence of exact knowledge, these quantities may be treated as distance-dependent stationary random processes. However, these distance-dep

An alternative to the standard astrogeodetic and gravimetric methods for estimating vertical deflections is described. This technique, which is particularly well suited to surveys from moving vehicles, utilizes an inertial navigation system, a geodet
