Who We Are
We are a team of five young scientists and engineers who are building a CanSat - a small satellite with its real mission.
We come from Prague, which is the capital of the Czech Republic. All of us are members of the OK1RAJ amateur radio club.
As we are the winners of the Czech national CanSat competition, we are now preparing for the 2017 European CanSat launch campaign. This is going to take place at ZARM in Bremen, Germany.
Now we are working on our new CanSat, which is called RAJsat4.
I am the electronics and PCBs designer.
I am the main programmer. I am preparing the firmware for RAJsat4.
I am responsible for creating the website and informing people about our project.
My task is to prepare the ground station for receiving the data correctly.
My job is to choose the best parachute and to make sure that RAJsat4 is resistant to mechanical damage.
I am preparing the ground station and assembling the PCBs.
The New Dimension of CanSat
RAJsat4 brings lots of new features to CanSat construction:
RAJsat4 uses the powerful ATmega2560 microcontroller.
Information about RAJsat4's position is transmitted to the ground station. Additional systems are provided as well.
Charging the batteries is so easy! Solar cells or USB can be used.
Thanks to its construction, RAJsat4 can survive many impacts and shocks.
A lot of different modules can be connected in order to realize specific measurements. This also makes RAJsat4 easy to repair.
All the measured data are saved to microSD card and it can be later analyzed.
Our CanSat's secondary mission is to measure various physical quantities that describe air conditions and qualities. RAJsat4 measures air temperature and pressure, humidity and quantity of air contaminants. We also want to know what happens to our CanSat during the flight - that's why RAJsat4 also has accelerometer, gyroscope and compass module. A camera is included in our CanSat, too.
Aside from measuring a lot of interesting data, we want to visualize it during our CanSat's flight. It is possible to check temperature, pressure and humidity thanks to our web app. A meteo station, which shows current temperature & pressure status at the ground station, is another part of our CanSat project.
Czech National Competition
The Czech national CanSat competition final, held by ESERO Czech Republic, took place at the Letkov airport near Pilsen. Eight CanSats from teams around Czechia were dropped from a drone and started to perform their missions. Our team RAJsat won first place so we are going to participate in the 2017 European CanSat competition!
