However, it won't automatically determine the distance to asteroids. "When asteroids are measured with short observation time windows ... a single observatory can measure parallax because the ...

Measuring the distance using lasers is a mainstay of self-driving vehicles and ambitious robotics projects. The fine folks at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL ...

To do this, you need to measure the time it takes a sound to travel a measured distance. To reduce errors, particularly timing errors, you should either: use a large distance (preferably over 100 ...
