1. A system comprising:
- a first device for measuring the length of a transmission route to a platform;
a second device for transmitting complex measuring or reference signals; and
apparatus for correcting said complex measuring or reference signals transmitted by said second device, based on the length of said transmission route measured by said first device;
whereincomponents of the second device are mounted adjacent components of the first device such that the changes of the length of the transmission route are the same for both devices.

Abstract
A method and apparatus for wireless transmission of electrically complex or phase-critical signals includes a device for measuring the length of a transmission route to a moving platform, and a device for transmitting complex measuring or reference signals. According to the invention, components of the device for transmitting the signals are arranged adjacent components of the device for measuring the length of the transmission route, so that changes of the length of the transmission route are the same for both devices.

8. Apparatus for wireless transmission of phase-critical signals between first and second relatively movable locations, said apparatus comprising:
-
a wireless device for transmitting or receiving said phase-critical signals via a transmission path between said first location and said second location, said transmission path having a path length that varies in response to relative movement of said first and second locations; measurement apparatus for measuring said path length; and apparatus for correcting a phase of said phase-critical signal received at one said first and second locations based on said measured path length; wherein, said wireless device and said measurement apparatus are mounted adjacent, and in close proximity, to each other, such that changes in said path length are the same for both said transmitter and said measurement apparatus. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
