Description

Method

Test (if applicable)

The system shall be composed of a controller (implemented on a handyboard), a

workstation simulation of the Mars Lander, a graphics package (which shall be

supplied to the developer) and a serial interface (cable and software) to connect

the controller to the workstation.

Inspection

n/a

The Mars Lander simulation shall begin to execute on the workstation.

Test

The simulation ends when the Mars Lander softly comes to rest on the surface

of Mars, when it crashes into the planet, or when it rises above its initial

altitude.

Test

Demo

When the spacecraft is allowed to free fall (no thrust), it shall crash into the

Mars surface in approximately 16 seconds.

Test

Demo

With thrust, the user should be able to land the spacecraft softly on Mars.

Test

Demo

The controller shall operate as the user’s interface to the Mars Lander Vehicle.

Test

Upon receipt of a data packet (1 byte) from the simulation, the controller shall:

1. Display vehicle altitude and vehicle velocity (both plus & minus) on the

handyboard LCD.

Test

Demo

Upon receipt of a data packet (1 byte) from the simulation, the controller shall:

2. Light the LEDs if the “Fuel Out” bit is on.

Test

Demo

Upon receipt of a data packet (1 byte) from the simulation, the controller shall:

3. Format a data packet and send it to the simulation.

Test

This data packet shall contain a “thrust on/off” indication. When the start

button is depressed, the controller shall indicate a “thrust on” condition to the

simulation. This condition will remain “on” until the stop button has been

depressed (even through subsequent transmissions of the data packet to the

simulation). When the stop button is depressed, the controller shall indicate a

“thrust off” condition to the simulation. This condition shall remain until the

start button is pressed.

Test

The simulation will track fuel remaining and send a flag to the controller

identifying when the fuel is out. If the vehicle has run out of fuel, the

simulation will not process any more thrust commands from the controller.
