In fact, according to the experiment, instruments operating at a frequency of 800-900 MHz,could strongly influence the navigation equipment of the aircraft.
This information, combined with the distance traveled, allows the navigation system to correctly determine the vehicle's position, even when the satellite signal is blocked in a crowded downtown area or a tunnel.
Today it is particularly interesting to predict the meteorological conditions in space: systems that help to anticipate and measure the effect of solar activity on applications andservices using satellite navigation systems are therefore necessary.
The interface circuits aredesigned to be shared by a number of new-type navigation devices, and each type of interface circuit can be combined and selected according to each signal format and the number of connections.
Technical details We assume that when time synchronizing with navigation satellites, signals from at least four satellites must be received simultaneously to compute the four parameters of time and the 3D coordinates of the receiver location.
We offer maintenance services for the Automatic Flight Inspection System(AFIS), which has been used to test inspection equipment,such as instrument landing systems, navigation support systems, and wireless communication systems, installed in airports.
