coarse sun sensor in matlab

To utilize a coarse sun sensor in Matlab for satellite attitude determination, you can follow the steps below:

1. Define the characteristics and specifications of the sun sensor such as the field of view, sensitivity range, and output range.
2. Create a model that simulates the sun sensor output based on the given inputs such as the sun altitude and azimuth angles.
3. Implement an algorithm that computes the attitude of the satellite using the sensor readings and other sensor data.
4. Test the algorithm and make necessary adjustments and improvements as needed.

Here's a sample code snippet that simulates a coarse sun sensor output based on the sun's position in the sky:

main.m
% Define sun sensor specifications
fov = 60; % field of view in degrees
sensitivity = 0.1; % output voltage per degree
output_range = [-5 5]; % sensor output range in volts

% Generate sample sun position data
sun_azimuth = linspace(-180, 180, 361); % azimuth angle in degrees
sun_altitude = 30*ones(1, 361); % altitude angle in degrees

% Simulate sun sensor output
sensor_output = sensitivity*fov/2 - sensitivity*abs(sun_azimuth); % compute sensor output in volts
% Clip output range
sensor_output(sensor_output < output_range(1)) = output_range(1);
sensor_output(sensor_output > output_range(2)) = output_range(2);

% Visualize sensor output
plot(sun_azimuth, sensor_output);
xlabel('Sun azimuth (degrees)');
ylabel('Sensor output (volts)');

This code generates a plot of the sun sensor output as a function of the sun's azimuth angle. You can modify the parameters to simulate different sensor specifications and test the output with your attitude determination algorithm.
