Rocket Altimeter Application

This repository hosts a NuttX application that performs altimeter calculations for rocket recovery system deployment, altitude tracking and logging. It also contains tools for testing the altimeter logic without access to the direct sensor hardware.

This is intended to run on the peanut altimeter, but is written to at least partially work on other NuttX-based altimeter systems.

In order to use this application, just clone this repository in your nuttx-apps directory. It will be detected by Kconfig and can be selected/configured as normal through the NuttX build system.

$ cd nuttx-apps
$ git clone https://github.com/linguini1/rocket-altimeter.git

Mocking

To mock-test the altimeter logic, you should enable both the processing application(s) and the fake_baro application. Once you've configured both programs to your liking, run them in the following order:

nsh> fake_baro; altitude_fusion &; velocity_fusion & events_topic &;
nsh> deployment &

You can then look at the published data from the topics using uorb_listener, which is one of the stock NuttX apps.

It is likely preferred to do this mocking on the sim architecture. In this case, you can copy one of the data.csv files from the fake_baro test data collection to your main NuttX directory. When you run the simulator, the CSV file will then be accessible from data/data.csv.
