development team. The requirements were set before launch.
B.
CanSat
CanSat is the main payload. Avionics and structure could be named as CanSat. There are several CanSat requirements. Different competitions have their own requirements, but can generalize some main requirements. These are;[1]
•Keywords-component; CanSat, Guidance, Navigation, Flight Control
All the components (CanSat, parachute etc.) shall fit in the rocket cargo.
I.
CONCEPT
•
CanSat concept was proposed by Prof. Twiggs in 1998. The main idea behind a CanSat was to create a simple satellite-like device by students, to gain hands-on experience. Generally LEO satellites have around 10min communication time.
The CanSatshall be compatible with the launching system.
•
The CanSat should have a recovery system like a parachute to be able to be reused after launch.
Typically a 4 km altitude launched CanSat also have around 10 min fly time. In CanSat mission students can read sensors on board and simply they can simulate a simple satellite. There are two important things to consider. These are the launcher and theCanSat itself.
A.
• •
CanSats can use RF communications. CanSats with RF Transmitters shall have properly licensed operators; Depending on the competition the total cost of the CanSat cannot exceed a certain amount. (in this case 50.000¥)
Launcher
The launcher is used to send the CanSat into a certain altitude. For launch rockets, helicopters, basically anything balloons, that UAV's, couldplanes or be used. flies
•
Volume: The CanSat should be equal or smaller than a cylinder with dimensions of Wcm radius and 26cm height.
Generally a rocket is used for competitions or main mission. For testing a balloon or a helicopter is more reliable and cheap solution. In this case a rocket is used for the main launch and a balloon is used for testing. For a safe launch a launch site was defmedfor this case. After the ejection the rocket opens its own parachute for a safe return.
• •
Mass: The CanSat mass is defined by the rocket, thus the heavier mass means lower altitude. For a safe parachute opening altitude mass of the CanSat should be lower than 1kg The CanSat should be able to eject when the cargo bay opens after reaching the apogee.

Rover Para-glider Glider
•
•
Surely the most successfully one of these methods is the rover. Rover is a simple toy -car which goes to the target after it lands. Landing is aided by a simple parachute. After landing the rover comes out of the parachute and simply navigates to the target by onboard avionics. Rover is successfulbecause it is simple, it doesn't require any complex flight systems. All it needs is to roll the tires until it reaches the target. Para-glider is simply a parachute with controller. It is easier compared to glider, due to its static stable nature. As a controller para-glider has two strings attached to the parachute. If the strmg on the right should be pulled the para glider will try to turn...
