CoLiTec published article in MNRAS

24 June, 2015 Oxford Journals published new article «A new method based on the subpixel Gaussian model for accurate estimation of asteroid coordinates» in «Monthly Notices of the Royal Astronomical Society» journal (Impact Factor – 5.107 & 5-Yr impact factor – 4.734).

We describe a new iteration method to estimate asteroid coordinates, based on a subpixel Gaussian model of the discrete object image. The method has been tested as the basis of our Collection Light Technology (COLITEC) software. For demonstration abilities of described method the article contains MPC (Minor Planet Center) data by accuracy «ТОP-20» most effective world asteroid surveys by 2011-2013 years. Data is presented in graphical and table view.

Article contains accuracy comparison between CoLiTec and Astrometrica software by the same series of frames. This comparison of the statistical characteristics of measurements indicates that the limits of reliable measurements from CoLiTec software are more wide, than from Astrometrica software. This benefit corresponds to the extremely low SNR, so in the result objects is not observable by eye. This range of low SNR is more important because all objects in it are new. The results are about the same when SNR value is greater than 6.

Also accuracy parameters of «ТОP-30» most effective world asteroid surveys are available in ««ТОP-30»» section.

CoLiTec and 2015 IAA Planetary Defense Conference, ESA/ESRIN, 13-17 April 2015

The International Academy of Astronautics held its 4th IAA Planetary Defense Conference. It took place from 13 to 17 April, 2015 in Frascati, Italy.

4th IAA Planetary Defence Conference - PDC 2015

There were some goals of the conference:

  • Planetary Defense – Recent Progress & Plans
  • NEO Discovery
  • NEO Characterization
  • Mitigation Techniques & Missions
  • Impact Effects that Inform Warning, Mitigation & Costs
  • Consequence Management & Education

This excellent IAA Planetary Defence Conference – PDC 2015 – concluded on Friday 17 April after 5 hectic days of exemplary presentations: nearly 250 participants and 170 Papers and Posters. Sergii Khlamov, software development Team Lead of CoLiTeс team with perfect posters and presentation took a part of conference. Sergii’s posters mainly focused on the astrometric reduction of the frame based on UCAC4 catalog and provide an analysis of its results. The comparative analysis of the accuracy was performed between the CoLiTeс and Astrometrica software. The analysis showed the benefits of the CoLiTeс software using with astrometry of asteroids in relation with Astrometrica using, especially when using wide field and low quality frames. The posters and presentation aroused a great interest.
