摘要： Systems and methods for differential altitude estimation utilizing spatial interpolation of pressure sensor data are provided. In one embodiment, a method for mobile navigation comprises: measuring a horizontal location of a mobile navigation unit to generate two-dimensional horizontal coordinate data; measuring a barometric pressure at the mobile navigation unit with a sensor to obtain local pressure data; processing information representative of pressure data derived from a network of a plurality reference stations to obtain a correction factor; performing a calculation using the two-dimensional horizontal coordinate data, the local pressure data, and the correction factor to calculate an altitude coordinate; and determining an altitude of the mobile navigation unit from the altitude coordinate.

摘要： Systems and methods for a target locator device are provided. In one embodiment, a target locator device comprises: a high performance gyroscope; an inertial measurement unit including an accelerometer triad and a gyroscope triad; a rangefinder; a global navigation satellite system (GNSS) receiver; and a processor coupled to the high performance gyroscope, the inertial measurement unit, the rangefinder and the GNSS receiver. The processor derives an alignment heading from a heading measurement provided by the high performance gyroscope. The processor calculates a heading to a target based on a deviation from the alignment heading as measured from a heading and elevation measurement determined from the inertial measurement unit.

摘要： A navigation system includes host and remote units. Host unit includes positioning device to determine absolute position/orientation of host unit; first communication device to communicate signals; first processor; and first memory. Remote unit includes second communication device to receive signals from first communication device; second processor; and second memory. First or second processor compares first aspects of known pattern with second aspects of image of captured pattern positioned on surface at either host unit or remote unit. First or second processor determines relative position/orientation of remote unit relative to host unit based on comparison of first aspects and second aspects. First or second processor determines absolute position/orientation of remote unit based on relative position/orientation of remote unit relative to host unit and absolute position/orientation of host unit. Either absolute position/orientation of host unit or absolute position/orientation of remote unit are communicated from host unit to remote unit.

摘要： A method of navigating based on terrain features is disclosed. The method identifies a set of terrain features of an area substantially surrounding a navigation platform having a system for simultaneous localization and mapping. For each terrain feature identified, the method records current navigational data as the navigation platform traverses the area, and correlates the current navigational data of each of the identified local terrain features with prior navigational data of previously-determined terrain features from an existing terrain mapping database accessed by the navigation platform to within a prescribed correlation threshold. From at least the correlated navigational data of the identified terrain features, the method provides a current position estimate for the navigation platform.
