====== ESA Summer of Code in Space 2013 ======

===== Ideas =====

- Extend open-source toolkit which can be used as an substitute for closed souce programs.
   - Design and implement reliable algorithms for distinguishing different types of meteors.

==== Open-source meteor detection toolkit ====
=== Brief explanation ===

RMDS01A is a SDR receiver designed for radio detection of meteor trails. It's advantage over other designs is a high performance software defined receiver and completely open-source design, which allows for advanced signal processing of radio images. The primary setup we used included non open-source software like Spectrumlab and HDSDR. We therefore developed completely open-source alternative.
== Software for RMDS01A ==
[[cs:RMDS]]

Most important pieces of software are done. What is needed is to glue them together to cooperate flawlessly. 
For data acquisition we created program [[https://github.com/nnen/waterfall|waterfall]] which reads input from SDR receiver and generates both FITS raw files and jpeg previews of these files for interactive visual inspection. 
For data synchronization with other nodes a set of [[http://www.mlab.cz/WebSVN/listing.php?repname=MLAB&path=%2FDesigns%2FMeasuring_instruments%2FRMDS01A%2FSW%2FTools%2F#_Designs_Measuring_instruments_RMDS01A_SW_Tools_|bash scripts]] is used. Basic HTML5 interface was developed for live inspection of the received stream by many concurrent users over the internet.

==Proposed projects:==
  - **Difficulty**: //medium// **Importance**: //high//. GUI to glue all above mentioned software together to provide solid user experience and ease of use. 
  - **Difficulty**: //easy// **Importance**: //medium//. Finish the HTML5 GUI for watching live streams, implement interactive elements (like LO frequency changing). Optimize for use with mobile devices (tablets, smartphones).
  - **Difficulty**: //hard// **Importance**: //medium//. Implement algorithms for trajectory calculation of meteors. We will provide all algorithms to be implemented. Some very basic example: http://meteor.uwo.ca/research/radar/cmor_intro.html
  - **Difficulty**: //medium// **Importance**: //medium. Design and implement robust algorithms for processing the signal. The recommendations are to use one of: [[http://root.cern.ch/drupal/|ROOT]], [[http://www.gnu.org/software/octave/|GNU Octave]], [[http://www.r-project.org/|R]].

=== Expected results ===

Single package which will be able to install software needed for viewing, detection, collection and processing of meteor signals.

=== Knowledge prerequisites ===

* Knowledge of programming languages necessary to implement the solution (C/C++ preferred for performance reasons).
  * Ability to use/learn to use basic development tools (IDE, version control software, issue tracking systems).
  * Ability to learn and use third-party libraries necessary to implement the solution (CFITSIO, libfft, libusb, ...).
  * Some math skills, at least has to know what Fourier transform does.
  * Knowledge of most used data structures and algorithms, network and thread programming.
