How does Bolidozor network work Bolidozor is a network designed for meteor observations on different level of professionalism. It uses observation stations located either at amateurs, volunteer or at professional or public astronomical observatories. The map with locations of the stations can be found at

Methods of data processing used in Bolidozor network This site contains several designs of algorithms used for data processing. * Estimate of an vector of meteor in the atmosphere * Record of available meteorological data for future reconstructions (satellite images, ČHMÚ measurements at a particular time, radar images)

antennas

Anonymous (anonymous@undisclosed.example.com) — 2019-07-13T12:27:26+00:00

Antennas for Bolidozor network Antenna is the first signal input to a radio detection station. It is therefore necessary not to neglect its choice as a signal that is not received cannot be processed. A typical radio antenna receives not only meteor reflections, but also other radio signals - thus, the location of antenna is of high importance and should be chosen carefully. Suitable antenna characteristics can make the choice of location easier and can improve the overall antenna gain. Advanta…

Upload system for data measured by stations Measured data upload from stations uses python software data-uploader. It can be used to upload data of Bolidozor and Ionozor projects. Upload to central server works via SSH protocol. It is secured via an ssh-key. The software checks the integrity of an uploaded file during the process of data upload using a check sums. At the same time it provides an information about the new file on server to the indexing database.

Its disadvantage i that the radiation pattern drops sharply to zero at zenith, making it very difficult to detect meteors flying directly over the head (compared to visual observation).

How to register an observatory to the Bolidozor network Observatory is a place where multiple measurement stations or project can be situated. The typical example of that place is an astronomical observatory. Stations send files containing measured data to the server space.astro.cz through SCP protocol. At first, a station has to generate a key pair (if it has not done it already), that will be used for station authentication when communicating with server.
