![Test](https://github.com/iwishiwasaneagle/proportional_navigation/workflows/Python%20package/badge.svg) [![PyPI version](https://badge.fury.io/py/proportional-navigation.svg)](https://badge.fury.io/py/proportional-navigation) ![PyPI - Python Version](https://img.shields.io/pypi/pyversions/proportional_navigation) [![Coverage Status](https://coveralls.io/repos/github/iwishiwasaneagle/proportional_navigation/badge.svg?branch=master)](https://coveralls.io/github/iwishiwasaneagle/proportional_navigation?branch=master) [![Downloads](https://pepy.tech/badge/proportional-navigation)](https://pepy.tech/project/proportional-navigation)

A package to easily do [proportional navigation](https://en.wikipedia.org/wiki/Proportional_navigation). This navigation equation is popular for target-persuader Line-of-Sight applications, such as missiles. The popularity stems partially from it's simple implementation, and effectiveness.

## Explanation on notation

From the below figure, it is clear that we are using velocity/heading model for each body (`proportional_navigation.HeadingVelocity(psi,x,y,V)`). Such that V is the magnitude of velocity, psi is heading relative to world x-axis, and x and y of the body is relative to the world axes. However,`proportional_navigation.GlobalVelocity(x,y,xd,yd)` also exists for convenience.

```bash
git clone https://github.com/iwishiwasaneagle/proportional_navigation
cd proportional_navigation
python setup.py install
```
```bash
pip install proportional_navigation
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.
