Sensor Array

Sky Hub's open source platform allows for effortless expansions and future device support. To enhance the Sky Hub system we are developing support for a sensor array 📡

The current System diagram shows an outline of the proposed direction.

The sensor array will be a collection of devices that monitor the local environmental readings and relay data to the tracker.

Developing sensor support is a continuing mission of the Sky Hub team. The hardware we consider goes through a proposal phase and is vetted though the Development, Hardware, and Science teams.

The work for this is very fluid. However, below are details of what platforms and sensors we are currently evaluating.

The Sensor Array is a Work in Progress and requirements may change significantly. We encourage you to join in the debate on the future hardware on our live chat channel.

Example setup

The image below shows a sensor array currently under evaluation which includes Raspberry Pi 4B, a variety of Grove Sensors, Nooelec SDR kit.

Sensor array platform

Another micro computer will be at the heart of aquiring data directly from the sensors. We are exploring the Raspberry Pi and the 2GB Jetson Nano. Eventually the chosen device will be deployed on the same LAN as the Tracker as shown in our see system diagram.

If you would like to join development and testing of the sensor array the starting point platform and recommended acessories you will need are as follows.

Sensors in development

Witmotion HWT901B High Precision 10-Axis Military-grade Pitch Roll Yaw (X Y Z axis) Accelerometer + Angular Velocity + Angle +Magnet Field + Air Pressure + Altitude data

We may deprecate support for the Witmotion in favor of a sensor that is Grove-based.

Pro Stick Plus Flight tracking data using high performance ADS-B with Built-in 1090 MHz filter. Range over 275nm/500km depending on installation quality.

We will likely to deprecate support for the Flightaware Pro Stick, in favor of a Nooelec SDR kit for ADS-B which is currently under evaluation.

Sensors under evaluation

Grove

We are currently exploring the Grove suite which offer wide range of sensor types that are easy to connect and use. The Grove platform requires a Grove Hat in order to connect the sensors to the Raspberry Pi.

If you would like to join our development and testing of the Grove sensors the main acessories you will need are:
