Soon, cops to clear traffic in space
In a bid to avoid collisions between satellites and space debris, scientist are now using mini-satellites that work as ‘space cops’ to help control traffic up in the sky.
Scientists at California-based Lawrence Livermore National Laboratory used a series of six images over a 60-hour period taken from a ground-based satellite. They found that it is possible to refine the orbit of another satellite in low-earth orbit.
“Our mini-satellites would be orbiting and making the same sort of observations to help prevent satellite-on-satellite and satellite-on-debris collisions in space,” said Lance Simms, lead author.
Using the ground-based satellite, the Livermore team refined the orbit of the satellite ‘NORAD 27006′, based on the first four observations made within the initial 24 hours, and predicted NORAD’s trajectory to within less than 50 metres over the following 36 hours.
By refining the trajectory of ‘NORAD 27006′ with their ground-based payload, the team believes they would be able to do the same thing for other satellites and debris once their payload is orbiting earth, said the study published in the Journal of Small Satellites. — IANS
