GBGH has received the following awards and nominations. Way to go!
Now days , Determination of micrometeoroid/orbital debris (MMOD) impact on orbiting spacecraft requires visual inspection. For human-rated spacecraft such as the ISS and more ..
this has required crew time as well as vehicle assets to identify damage due to MMOD strikes
And with the high augmentation of orbital debris since 1960
We became conscious of the necessity of devices that limits mmod damage inspection time and reduces the humain involvement.
That’s why we created Sauron
, a free-flyer that imitates the bat soundwave scouting system.
But because sound is a mechanical wave that doest propagate in the vacuum
Sauren intends to exploit electromagnetic waves by using 3d laser scanning technology to detect and analyse mmod impact on spacecrafts in an optimal time without the requirement of humain assistance .
1 - Laser scanning process :
The laser probe projects a line of laser light onto the surface
(img.1)generating a XYZ coordinates for each point captured to create a point cloud sample ( up to 1.000.000 point/sec/m²) of the scanned area (img.2)
To calculate the time needed to scan the whole surface
Where T: time needed to scan the whole area
S : the surface of the spacecraft
N : number of 3d scanners
We took iss as an example so we tried to calculate its whole surface area by using a 3d model in 1/100 scale
That it gives us a surface equivalent to 1m² * 100² = 10.000 m²
After doing a simulation we concluded that we need from 4 to 6 scanners to cover the whole surface so
So T = 2000sec = 33 min 20 sec
