Introduction

• Jetdrop 3000
• Altimeter for a rocket that delivers data down to the ground and

drops an object in a parachute at a certain height.

• Target audiance: Students at the Swedish technical school.
• Problem: Rocket modelers can always use a cool addition to their

rockets.

Use case

Figure 2: The Swedish flag [15]

• Customer selects what item he wants to drop
• Customer selects whether he wants to drop manually or

automatically at a certain height

Customer Needs

Figure 3: Our Swedish friends building the rocket at the [AA15]

CN0 To know the altitude of the rocket at any given time. CN1 To drop a thing down from the rocket. CN2 To get pictures or videos from the rocket.

Design: Modules

• 2 modules: Flight computer and mission control
• Altimeter (DP0) is on the flight computer
• Hatch (DP1) is also on the flight computer
• The item to be dropped (fx. a camera) is also on the flight

computer

• Hatch open command can be sent from mission control
• Hatch can be automatically opened at a certain height
