Apparently Litton, Elliots and Ferranti all competed for the P.1154 contract, there was some controversy surrounding the Litton offering due to reports from Germany that the LN3 had suffered from poor reliability, however this was contradicted by Canadian experience.

Hi there, maybe this post is a little late, but I just came accross this thread which I
found very interesting. My hobby is vintage avionics and I restored a FIN1012 to
working condition and via a homebrew logger/debugger it now controls the original
35mm film based moving map display. You can find a video on this project here:

   

Although I have a good understanding on the internals of these systems now, I'd
be highly interested getting in touch with someone who knows on manufacturing and
facory-calibration of the platforms. They are really a masterpiece of engineering
and the FIN101x's are a great mix of precision mechanics, analog and digital computing!

Any hints are welcome,

Erik,

Unfortunately I cannot help with your request, but I'm lost in admiration at your patience and ingenuity! Watching that gyro-package move as you're handling it in that video is hypnotic!

Thanks for the positive words... I think wihin the next year I will do another video with more detailed views of
the mechanics in action (esp. during alignment and moving it around). A friend is working on the original HUD and
if this will be fed by the navigator, this will be another video, too...

Unfortunately I did not get any feedback on possible ex-Ferranti empliyes so far, still remembering these
systems...   :'(

Just trying to bump this thread up a bit and trigger some further discussion. I'm trying to compile a brief summary/history of Ferranti INS data/FIN numbers etc just for prosperity.

Can anyone add to any of the info already presented? ie what was the FE designation number for the Phantom INAS? Were the Black Arrow/ELDO systems complete platforms or did Ferranti just supply the gyros into those programmes? What was provided for "Skylark"?

I worked on the Harrier/Phantom INAS equipment in the late 70s/early 80s (as a bright-eyed bushy-tailed new physics graduate!) and fondly remember being considered part of the "valve and relay" department. That equipment was surely the pinnacle of Ferranti's work in the field of analogue military electronics! One of my first jobs was redesigning part of the Phantom navigation computer to replace Resistor-Transistor Logic (RTL) circuit cards with TTL devices!
I was also involved in the FINRAE system, which was designed and built in 3 weeks then shipped to the South Atlantic for the Falklands War in 1982.
