A search and rescue transponder device targeted for the use of Filipino fisherfolk and other stakeholders. Works on the ESP32 microcontroller with LoRa and GPS modules.

In fulfillment of the final project requirement for CMSC 205: Data Communications and Networking

This project was formerly known as fisherNET. The project's renaming was done in view of an expansion of the project's original vision.
