Claim 0:
1. A method for enhancing a navigation solution of a device and a platform, wherein the method is operable when the mobility of the device is constrained within the platform and when mobility of the device is unconstrained within the platform, wherein the device is configured to receive readings related to navigational information from the platform via a wired or wireless connection,
wherein the platform comprises at least one sensor and the readings related to navigational information comprise information from the at least one sensor, and wherein the sensor information is used to resolve at least one of attitude of the device and misalignment between the device and the platform, by:
a) obtaining the information from the at least one sensor;
b) choosing multiple possible candidates of the at least one of attitude and misalignment,
c) determining candidate specific forces at the device for each of the chosen candidates of the at least one of attitude and misalignment, using the sensor information and the chosen candidates;
d) comparing the determined candidate specific forces to specific forces measured by the device;
e) estimating the at least one of attitude and misalignment value by assessing each chosen candidate of the at least one of attitude and misalignment based on the comparison of step d) of this claim; and
f) providing the at least one of attitude and misalignment.
