-==== Video meteor detection system ==== 
  
-Several projects of visual meteor detection software currently exist. But neither is open-source and all of them have poor results and large false positive detection rates. We need a high quality video meteor detection system for evaluation of our radio meteor detection metods.  +===== Tasks for SOCIS participants =====
  
-Video data will be collected by our design of [[cs:vmds|visual meteor detection station (VMDS01A)]] (part of our project)Meteor trails within these video data have to be detected in real-timeMeteor trails must be interpreted in physical context (meteoroid explosionstrail clouds coveradge, etc.). Following this, geometric parameters can be delivered and orbit parameters can be calculated+There are several tasks for SOCIS participants in the summer 2015 you can choose one. There are brief description of problems and description of initial task for qualifying of you for these tasksIf you are interested in the tasks presented here please do not hesitate to contact us at bolidozor@googlegroups.comwe will send you a technical detailsWe will help you with your deal.

-Design and implement reliable algorithms for real time meteor detection from video dataAlgorithms for distinguishing of different types of meteors are welcomed. The used algorithm should be based on currently existing software imprementation.+There is a new radio meteor detection station RMDS02D developedThis station has abilities for radio interferometry detection of meteor trails with use of two antennas at an observatory site. The software for computation of heading to the meteor from two records taken in same time with RMDS02D from two or more antennas.

New connection module for GHPSDR is a task for a student for showing his/her skills. 
  
-Measuring station is a complex computer based system which needs internal self checking, failure detection, calibration and continuous maintenance of data collection. A software to carry out these tasks is required. It should generate reports concerning station health and upload these files to the data server. +=== Project details ===
  
-=== Expected results ===+With use of interferometry the direction of target object can be discovered. We intended to use two FITS radio reflexion record for determine of direction to reflection. The radio-observer application has to be extended for simultaneous recording of two two signals from two radios with synchronised Local Oscillator. These two records can be used for calculation of correlation. Finally the direction of reflected signal will be found from this correlation. Student helps community with acquisition of another information from meteor trails records.

Some research is needed. The student has to search for existing technologies for Citizen Science (like CrowdCrafting, PyBossa, Zooniverse,...) and then he or she has to program a Citizen Science application for searching for meteors coincidences in records of Bolidozor’s radio meteors database which supports Czech Astronomical Society.

The waterfall visualisation snapshot from each record exists (see picture). It has to be find the same meteor detected by one station in records of other station or stations. Then exact time and other specific parameters of detection has to be determined by human. 
 +A HTML5 web interface should be developed for live inspection of the received stream by many concurrent users over the internet. 
  
-Combination of radio-observer with the Basic radio astronomy station design brings opportunity to detect radio bursts exited by solar flaresThese data are useful for HeliophysicsHowever, a solar radio burst is weak compared to the local man-made noise and signal must therefore be cleared of this noise before the detection and classification+{{:cs:sdr:5-06.27.14-10_08_15.jpg?700|Meteor Records}}
  
-{{ :cs:designs:measuring:ionosphere.jpg?500 | Ionosphere measurement by SDRX01B}}+There are a sample of records from two station 50 km away each otherThere are two detections of possible identical meteor. Relative shift of this detections from a time mark (horizontal line in signal) has to be found for next computation of meteor trail. Some estimation of region of meteor occurrence can be determined from this measurement. The student will adopt some skills of use of bistatic radar in space science by meteors detection in this project.
