Quick Answer
Yes, Meshtastic radios can be used for group tracking, providing a low-cost, low-power solution for locating and tracing groups in various environments.
Setting Up a Mesh Network for Group Tracking
Meshtastic radios use the LoRa mesh protocol to establish a decentralized network. To enable group tracking, a minimum of three Meshtastic devices are required. These devices can be connected to a central hub or gateway, which relays location data to a central server or cloud-based platform for analysis.
Configuring Devices and Gateways
To configure a Meshtastic network for group tracking, devices must be paired and configured to communicate with each other. This involves setting the network ID, frequency, and transmission power for each device. A gateway, such as a Raspberry Pi or a dedicated device like the Meshtastic Hub, can be used to aggregate data from the mesh network and forward it to a central server for analysis. In a group tracking scenario, devices can be set to send periodic location updates to the gateway, which can then forward these updates to the central server.
Analyzing Location Data
To analyze location data from the Meshtastic network, a data platform like InfluxDB or a cloud-based service like AWS IoT can be used. This platform can store and process location data from the gateway, allowing for real-time tracking and analysis of group movements. Using tools like GeoJSON or Leaflet, location data can be visualized on a map, providing a clear view of group movements and trajectory.
