BDSAT (BD SAT, CZE-BDSAT, BDSat-1)

Amateur radio mission and test of pressure sensors and supercapacitor bank.

Experimental payload subsystem is developed to verify and qualify pressure sensor devices for use in open space conditions. On top of technical verification, feasibility and suitability of the technology will be studied. The second part of the experiment aims to verify supercapacitor technology as a modern energy storage solution.

BDSAT project aims to support the radio amateur community with several HAM services and activities. Secondary goal is a verification of a prototype of pressure measuring equipment and to verify the functionality of this technology in open space conditions. The function of the measurement itself, its feasibility and suitability for use in satellites in space conditions will be verified. The second part of the technological experiment is to verify use of supercapacitors as a modern approach to energy storage in satellites.

The BDSAT project is divided into two parts. First at all, it will test BD SENSORS pressure transmitters in open space conditions. These transmitters have to meet very demanding requirements both in terms of survival in harsh space conditions and in terms of maintaining accuracy and other technical parameters. The reliability of the technology is essential to the future space applications.

A base station for communication with the satellite will be located at the co-investigator CEITEC VUT, which will provide the command and data collection from the satellite.

The experiment also includes verifying the function of the supercapacitor bank. It is a powerful source for storing electricity for satellite systems. In the future, a supercapacitor bank can replace conventional battery power systems. The system will be charged with energy from solar panels during the flight phase facing the Sun. During the second phase of the flight without the power from the solar panels, the energy from this source will be discharged to an artificial load.
