# CUSF standalone predictor

Working on improving the Cambridge University Spaceflight landing predictor, used for predicting the flight path and landing location of latex balloons.  

## Install

The source for the prediction software itself is in pred_src and instructions for building it can be found there.  

The `predict/preds/` directory needs to have rwx access by the PHP interpreter and the `predict.py` python script. You will need to install the following python packages: pydap, numpy, json, simple-json.  

Other than that, just clone this repo to a non web-accessible folder and create symlinks to the `predict/` and `hourly-predictions/` directorys in the repo.  

## Information

A cronjob should be run to delete directories in the `preds/` directory after a given number of days, perhaps 7 or 10.  

The directory names are UUIDs comprised of an SHA1 hash of the launch parameters, and re-running predictions will overwrite data in the existing directory, rather than create a new one.
