Abstract
Abstract Launcher for a tube-launched, optically guided wire controlled missile. Inhe electronic circuitry that forms part of a feedback servomechanism there are provided pitch and yaw channels with time variable gains having different transfer functions. Optionally there are further provided at least two different generators of signals for gravity bias with automatic means for selecting between them in accordance with the physical characteristics of the missile.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
87 words
A launcher for a tube-launched, optically guided, wire-controlled missile, comprising: a feedback servomechanism controlled loop including electronic circuitry having pitch and yaw channels, each of said pitch and yaw channels having respective time variable gain circuit means for acting on a respective one of pitch and yaw error signals in accordance with a respective transfer function, and wherein said transfer function of said time variable gain circuit of said pitch channel is different from said transfer function of said time variable gain circuit of said yaw channel.
Claim 2
Dependent Claim
87 words
A launcher for a tube-launched, optically guided, wire-controlled missile, comprising: a feedback servomechanism controlled loop including electronic circuitry having pitch and yaw channels, each of said pitch and yaw channels having respective time variable gain circuit means for acting on a respective one of pitch and yaw error signals in accordance with a respective transfer function, and wherein said transfer function of said time variable gain circuit of said pitch channel is different from said transfer function of said time variable gain circuit of said yaw channel.
Claim 3
Dependent Claim
21 words
A launcher for a tube-launched, optically guided, wire-controlled missile according to claim 1, characterized by comprising a time variable lead-lag filter.
Claim 4
Dependent Claim
29 words
A launcher for a tube-launched, optically guided, wire-controlled missile according to claim 2, characterized by comprising at least two discrete filters operating consecutively with automatic switch-over at predetermined times.
Claim 5
Dependent Claim
64 words
A launcher for a tube-launched, optically guided, wire-controlled missile according to claim 1, characterized in that the electronic circuitry comprises at least two different generators of signals for gravity bias associated with the pitch channel, in combination with automatic selector means by which a desired gravity bias signal generator is selected in accordance with the physical characteristics of the missile loaded in the launcher.
