en is open-source hardware and open-source software project which brings availability for effortless design and construction of various measurement devices for scientific purposes. Several space and astronomical measuring instruments exists in MLAB project. The Czech Astronomical Society gets involved by quality of data captured by our instruments and sets up a data storage server space.astro.cz for data collection from measuring stations. We want to improve our designs by software development supported by European Space Agency.

1. Expand existing station based measurements to cooperative sensor network overcoming professional astronomy measurements.
2. Design algorithms and implement technology for astronomy observations management on distributed sensor network.
3. Extend existing systems for easy implementation to whole EU region.

RMDS02C and its predecessor RMDS01 is a SDR receiver system designed primarily 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 brings advanced signal processing of radio images for everyone. This system now has several detection stations (see the map) in the Czech Republic and Slovakia. But technically is intended to expand to other European countries.

For data acquisition we are using our open-source software radio-observer which reads input from SDR receiver and generates FITS files with raw signal recording and stream of events connected to visualization program PySDR for on site interactive visual inspection.

The radio-obserer application was developed with support of ESA and now is deployed at new stations of new established Bolidozor detection network.

Consistent software package (ideally .deb installation file) which will be able to install necessary software for detection and collection of meteor signals for new measurement stations in the network.

Difficulty: medium Importance: high.

Implement new features and algorithm to PySDR software package for live 3D meteor visualization in astronomical observatories conference rooms.

Better HTML5 interface should be developed for live inspection of the received stream by many concurrent users over the internet.

Single package which will be able to install software needed for viewing and processing of meteor signals collected from measurement stations over internet.

Difficulty: medium Importance: medium. Finish the HTML5 and OpenGL GUI for watching live streams, implement interactive elements. Optimize for use with mobile devices (tablets, smartphones). Ability to learn and use third-party libraries necessary to implement the solution (CFITSIO, libfft, libusb, …)

Measuring station is complex computer based system which needs internal self checking, failure detection, calibration and continuous maintenance data collection. A software doing these tasks is needed. This software should generate reports about station health and upload these files to the data server.

Set of software scripts for performing station maintenance tasks with simple visualization of system states on station's local display.

Difficulty: easy Importance: medium. Knowledge of scripting languages is necessary to implement the solution (Python is preferred). Ability to use/learn to use basic development tools (IDE, version control software, issue tracking systems).

radio-observer should be used for other radio astronomy measurements using our designs of Basic or Advanced radio astronomy stations or well known Small Radio Telescope design

• Basic knowledge of signal analysis
• Good math skills, at least has to know what Fourier transform does.
• Knowledge of most used data structures and algorithms, networking and thread programming.

Combination of radio-observer with the Basic radio astronomy station design gets opportunity to detect radio bursts exited by solar flares. These data are useful for Heliophysics. But Solar radio burst is weak compared to local man made noise and signal must be cleared before detection and classification.

Set of software scripts constructed as plugins for radio-observer software. These scripts should implement signal purification in various radiotelescope designs.

Difficulty: hard Importance: high. Knowledge of scripting languages is necessary to implement the solution (Python is preferred). Ability to use/learn to use basic development tools (IDE, version control software, issue tracking systems).

Scalable design of our software defined receiver gives opportunity to use multiple antenna array for signal reception from Cubesat satellites. Cubesat development teams around the word are limited by signal reception from its home station or by volunteers which contributes by received data sets. This amateur LEO satellite reception methods can be easily improved by use of multiple fixed antenna array and beam-forming algorithm on reception station.

Set of software scripts constructed as plugins for radio-observer software for beam-forming algorithm application in multiple antenna array systems.

Difficulty: hard Importance: high. Knowledge of scripting languages is necessary to implement the solution (Python is preferred). Ability to use/learn to use basic development tools (IDE, version control software, issue tracking systems).

Several projects of visual meteor detection software currently exist. But neither is open-source and all these softwares were poor results and big false positive detection rates.

In our project video data will be collected by our design of visual meteor detection station (VMDS01A). Meteor trails must be detected in these video data in real-time. Meteor trails must be interpreted in physical context (meteoroid explosions, trail clouds coveradge, etc.). After this, geometric parameters can be delivered and orbit parameters can be calculated.

Design and implement reliable algorithms for real time meteor detection from video data. Algorithms for distinguishing of different types of meteors are welcomed.

Difficulty: hard Importance: medium. 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).
