I kind of missed or misunderstood how this device was supposed to know it's initial position. Was it preset on launch?

- chipsa 4y agoLaunch is always from the same spot. So yes.
- FeistySkink 4y agoSo it just starts ticking on lift off?
- ceejayoz 4y agoSounds like it. > The cosmonauts configured the Globus by turning knobs to set the spacecraft's initial position and orbital period. From there, the Globus electromechanically tracked the orbit. Unlike the Apollo Guidance Computer, the Globus did not receive navigational information from an inertial measurement unit (IMU) or other sources, so it did not know the spacecraft's real position. It was purely a display of the predicted position. I’d imagine they could error correct via ground triangulation of their signals periodically. Or looking out the window for a large distinctive landmark.
- kens 4y agoTurning the big knob on the front rotates the globe so you can set the position. I would assume that they set the position once they are in orbit and periodically make sure it still accurate.
