In this paper, a mechanism is designed for integration of inertial navigation system information (INS) and global positioning system information (GPS). In this type of system a series of mathematical and filtering algorithms with Tightly Coupled techniques with several objectives such as application of integrated navigation algorithms, precise calculation of flying object position, speed and at...

We present a tightly coupled array antenna excited by high-power photodiodes for millimeter wave transmit operation. The design includes thinned photodiode substrates improved bandwidth performance at high frequency combined with the inherently lightweight, low-loss, and direct feeding architecture afforded photonic approach. Circuit full simulations are conducted compared against traditional e...

As we stand at the portal of the next millennium, I am both excited and terrified about the future. I feel that as a modern civilization we may have become intoxicated by technology, and find ourselves involved in enterprises that push technology and build stuff just because we can do it. At the same time we confronted with a world that is increasing needful of vision and solutions for global p...

An approach to enhance the performance of tightly coupled GPS/INS systems is described. First, the advantages of tightly coupled systems compared to loosely coupled systems are clarified. Then, it is shown in hardware-in-the-loop tests and in a test drive that processing time differenced carrier phase measurements instead of delta-range measurements results in an increased velocity and attitude...
