How plan an imaging session for the ISS transit
How to find the ISS:
The ISS orbits the Earth at an amazing speed of 17510 miles per hour it. It also orbits the Earth once every 92 minutes. However due to the Earth’s rotation it would only pass by above you approximately twice a day Whether you get to see it then depends on a multitude of factors, such as whether it is sun lit or transiting across a bright object such as the Moon.
It would be fairly difficult to determine when we can see the ISS. Thankfully we know its orbit to a high accuracy and some wonderful scientists wrote an application to calculate its position and the multitude of factors that determine if it is sun lit or not.
Here are the applications we used:
Looks for when the ISS is passing over and if it is a sun lit transit or not.
Predicts if transit across celestial object would be happening.
The applications would also let you know in advance if the ISS will be transiting any objects. It is so accurate we managed to get the ISS to “touch” Saturn in our last imaging attempt, which really surprised us. The ISS looks like a streak due to its great speed. We’ll attempt again to get a sharp image of it, by a lunar transit the next time.
We were shooting at 14fps and the ISS only showed up around 7-8 times in the GIF. That is due to the limitation of our prototype hardware. The Tiny1 camera is designed to shoot at 60fps. We should get much more interesting results when the camera is ready for final tests.
