Abstract [en]

Asteroids are becoming a stepping stone for the human space exploration,as much as they are a threat for human life on Earth. Several agencies haveproved that sending spacecraft to an asteroid is already feasible so privatecompanies are starting to look into how to exploit this new resources we havenow at hand. However, asteroids are not easy to locate precisely in the exten-sive universe, and these missions require quite an accurate knowledge of theasteroid positions for long times.

For this reason, orbit determination algorithms are evolving very fast tocover these needs. But since Gauss, all the efforts have been put in improvingthe existing methods to make them more efficient and precise. But sometimesis good to take an step back and give it a different "view", is there a differentway of looking at the sky and obtain more information?. This paper want toexplore the feasibility of using trailed observations (streaks) for that purpose.Additionally to the standard right ascension and declination variables, streaksalso contains information about the angular rate of those variables, dRA anddDec. Using statistical ranging, a well established technique for asteroid orbitcomputation, a code has been developed to try and use these two new vari-ables that come with the the streaks. This paper will explain the code in detailand at the end will try to prove the validity of this method.
