GR - a technical query (IG methods etc.)

[Michael Lee Bailey]

p 306 GR - Amazon search reveals:
(thought I saw a reference to this in somebody
else's post awhile ago, but can't find it now --
apologies if this duplicates recent contributions)

"The current, flowing in the coil, passed a
Wheatstone bridge and charged up a capacitor.
The charge was the time integral of the current
flowing in the coil and bridge.  Advanced versions
of the so-called "IG" guidance integrated twics,
so the the charge gathering on one side of the capacitor
grew directly as the distance the Rocket had traveled.
Before launch, the other side of the cell had been charged
up to a level representing the distance to a particular
point in space.  Brennschluss exactly here would make
the Rocket go on to hit 1000 yards east of Waterloo
Station.  At the instant the charge (B sub 1 I (looks like))
accumulating in flight equaled the preset charge (A sub 1 I)
on the other side, the capacitor discharged.  A switch
closed, fuel cut off, burning ended.  The Rocket was on 
its own."

-- ie, that would be the IG (integral guidance) method ---

radio methods would be activating it via a transmitter
on the ground (I think Weissman is described doing this,
and having a 6th sense as to the best moment of pushing
the button...)

---- just to play with the concept a little,
Integrated Guidance falls in the category of
analog electronics, where levels of current and charge
are assigned "meaning" in a system -- sort of a 
semiotics of electricity (even digital devices are
based on this, aren't they: +5volts for 1, -5volts for 0)

or maybe IG stands for "internal guidance", ie all the guidance
hardware is on-board.
This totally gets into the issue of predestination...
the charge is set beforehand (like the watchmaker universe)
