I know the exact history of this item. It was originally purchased from a company called AST Servo in Newark New Jersey in the early 1980's by an associate of mine. AST bought it from a Surplus Government auction most likely in the 1970's. The three Honeywell HIG-4 (Hermetic Integrating Gyroscopes) were developed in the early 1950's by MIT labs near Boston, Massachusetts. Charles S. Draper was the main engineer behind this design and was known as the father of Inertial Guidance. This particular three axis strap-down system was part of a Radio-Inertial Guidance System used in the late 1950's. Look up Titan I Martin Marietta on Wikipedia for more information.
Incroyable cette architecture, un vrai système. Quel gain en poids et en complexité d'assemblage avec les techno plus moderne. Rien que le poids de la résine doit être très important. Merci pour cette jolie fenêtre du passé.
Somewhat tangentially, speaking of construction quality, a friend worked at a French military contractor that built sonar for submarines. This being 2004-ish he had an Xbox game console and decided to install a mod chip. Not being entirely proficient with a soldering iron he got someone in their hardware department to install it for him. Came back done to a similar spec with wire wrapping. Really wish I’d taken a photo!
Nice teardown , it has a serial number of 7 probably they didn't build a lot of items with this complexity , its a 3d labyrinthe with wires and cards ، the system was sealed i think resin was used for mechanical regidity not for protection against moisture.
Je suis tellement content de ne pas avoir à travailler sur des vieux systèmes comme ça. L'électronique moderne est tellement plus compréhensible même si elle est techniquement plus complexe.
Le gros problème ici, c’est d’accéder aux différents composants. Ça été étudié pour être « compact » (pour l’époque…), pas accessible. L’avantage de l’électronique moderne, c’est qu’on n’a plus ces potentiomètres de réglage, qui demandaient un temps fou pour la calibration (surtout qu’un potentiomètre pouvait en affecter un autre et qu’il fallait parfois revenir plusieurs fois sur les mêmes). Après, une fois qu’on a assimilé le synoptique, chaque module rempli une fonction simple, à l’époque : c’est relativement simple à réparer, d’autant plus qu’on a trois fois le même circuit, pour chaque gyroscope. Aujourd’hui, les auto tests aident à trouver la panne… mais parfois se trompent et la… c’est le drame! 😂 On peut passer un temps fou à trouver la cause du défaut, qui n’a aucun rapport visible avec les symptômes.
Yup now they could cram most of it on a single chip and replace the functionality of the system with 3 vibrating structure mems acellerometer chips in a small 2 cm cube.
Current inertial measurement units using MEMS gyros and accelerometers can be about a 1-inch (2.5 cm) cube or even smaller. The high-reliability ones are larger and use ring laser or fiber optic gyros. For reference, the Apollo IMU was a one-foot diameter sphere.
Wow that looks a lot like one out of a bomber carcass I helped dismantle a while back. Had lots of gauges in the cockpit that were painted in radium. 😂

The power of the internet! Thanks for the information. Great stuff!

It was an expensive purchase, but with more money, you get better stuff ! The construction quality of that time generator box is impressive.

Nice teardown.. Lol that's very complex but I'm pretty sure that thing can fit inside a very tiny tiny microchip with todays technology
It's all beautiful handwork.

Imagine service this back then
Wow, that was really high tech at that time.
What is inside of the giro tube?
Great video, thanks!
Эта штука стоит явно побольше мелких 1000 грина :-)
Very interesting!
This really drives home how much and how fast miniaturization has happened.

thanks for another great video :)
Fascinating, thank you.

Qual o ano de fabricação
One gyro is dated 1963, some capacitors 1958
