Skyward Software Development Assignment (2023-09)

Your task is to develop a simple program that mimics the main task of the flight software, detecting liftoff, apogee and landing events.

The structure is simple, the provided grader.c contains the actual main. It parses a csv file to read flight data, and calls first an init() funtion and then an update() function.

What you need to do is implement the two functions:

// This method will be called once to initialize your code.
void init() {
    // Your code here!
}

// This method will be called for every data point, simulating a full flight.
void update(float acc_x, float acc_y, float acc_z, float gyro_x, float gyro_y,
            float gyro_z, float baro) {
    // Your code here!
}

Then, inside your update function you will need to detect the appropriate events, and call the relative function at the correct time (liftoff(), apogee(), landed()).

You can look at the provided example.c for a very simple algorithm, that in practice would never work. In your implementation you should at least use the provided inputs to detect these events.

Measurement units and sensors

The input data comes from a 3-axis accelerometer, a 3-axis gyroscope and a barometer.

Here are the various measurement units:

data	unit
timestamp	us
accelerometer	m/s^2
gyroscope	rad/s
barometer	pascal
