| The purpose of this project involves the development of a GNSS receiver for land surveying applications. The receiver will provide accurate positioning on-site and provide a user friendly application for viewing the generated perimeters. All these features will be available at the press of a button, where the precise position will be stored in a database. | The purpose of this project involves the development of a GNSS receiver for land surveying applications.

| The following flowchart of the software architecture shows the states and transitions which the application will execute. Initially, the application configures the required peripherals and I/Os and then performs updates on the incoming NMEA sentences. When an interrupt is detected on the designated digital I/O pins, the application performs additional instructions in which it constructs the GeoJSON and sends it to the remote database. | The following flowchart of the software architecture shows the states and transitions which the application will execute.

| The main challenge in this project was that the React frontend required a certain type of JSON, so multiple changes had to be made in order for it to work. Also in the frontend, in order to represent the pins as a perimeter, multiple Open Street Map overlays had to be implemented and used (it is also the reason why the pins are editable via the map). | The main challenge in this project was that the React frontend required a certain type of JSON, so multiple changes had to be made in order for it to work.

| The approach is feasible as the only on-site constraint is the availability of the wireless connection and the internet is becoming available worldwide due to the emerging Starlink. It still requires more user-friendly interactions, but this proof of concept is enough to validate this application type. | The approach is feasible as the only on-site constraint is the availability of the wireless connection and the internet is becoming available worldwide due to the emerging Starlink.
