Title: Methods and apparatus for a navigation system with reduced susceptibility to interference and jamming
Inventor: WHELAN DAVID A
IPC: G01S1/00
Filed: 2006-11-06
Abstract: A navigation system provides a significant level of protection against all forms of interference or jamming to GPS in a cost-effective way. The system employs a network of ground reference stations and Low Earth Orbiting (LEO) satellites in conjunction with GPS. A common-view ranging geometry to a GPS satellite is established that links a reference station and a user. A second common-view geometry to a LEO satellite between the same reference station and user pair is also established. The ground stations synthesize real-time aiding signals by making carrier phase measurements of GPS the LEO satellite signals. This aiding information is transmitted via the LEO satellites to the user receiver at high power to penetrate ambient jamming. The user receiver locks onto the carrier phase of the LEO satellite, demodulates the aiding information, then applies the carrier phase measurements and the aiding information to enable extended coherent measurements of the GPS signals. The system thereby recovers the GPS signals that would otherwise be lost to the jamming.

Abstract: The invention relates to a filler material 1, 4, in particular for improving the quality of a joint seam formed during thermal joining of two metallic structural components 11, 12. According to the invention, the filler material 1, 4 comprises a core 2, 5 and a coating 3, 15 that surrounds said core at least in sections. Because the filler material comprises a coating 3, 15 on the core 2, 5, the alloying material for the coating 3, 15 may be selected largely independently of any possibly limiting metallurgical requirements in relation to the base material for the core 2, 5 so that with the use of the heterogeneous filler material 1, 4 according to the invention optimal joint seam characteristics of the joined structural components always result, largely irrespective of the materials composition of the core 2, 5. If an essentially H-shaped cross-sectional geometry of the filler material 1, 4 is used, moreover, preliminary fixing or alignment of the structural components 11, 12 that are to be joined in a thermal joining process becomes possible.

Abstract: Walk characteristics of an earth-boring rotary drill bit may be predicted by measuring locations and orientations of cutting elements thereof and calculating the magnitude and direction of an imbalance force of the drill bit using the measurements obtained. The calculated imbalance force may be compared to the imbalance force of at least one other drill bit having a calculated imbalance force and observed walk characteristics. An earth-boring rotary drill bit may be designed by constructing a database including the magnitude and direction of a calculated imbalance force and observed walk characteristics for a number of drill bits. Desired walk characteristics are selected, the database is referenced, and the bit may be configured to exhibit an imbalance force selected to impart desired walk characteristics to the drill bit. Drill bits are configured to exhibit an imbalance force oriented in a predetermined direction relative to a blade of the drill bit. A system may be employed to monitor the imbalance force of an operating drill bit and to provide or implement desirable operational parameters to compensate for same.
