The goal of the project was to create a communication system between a GPS receiver and an FTP server via GPRS. For this purpose, a programmable GPS receiver from Telit was used. A script was uploaded to the receiver, the compiled version of which the receiver executes every time it is turned on. The task of the script was to transmit the receiver’s navigation data using NMEA messages. A data file is created in real-time on the selected FTP server. The next stage is to properly format the received file and place it in a database table (created on the server). This is performed by an application run in any web browser. After this stage, the user can display the current navigation data of the receiver in the form of a webpage, selecting the characteristics of interest. An application was also created to convert measurement results into CSV format. It also allows for the selection of necessary data from the file.THE USE OF PYTHON PROGRAMMING LANGUAGE FOR DIRECT TELETRANSMISSION OF DATA FROM GPS RECEIVER TO FTP SERVER
The main goal of the experiment was to create a communication system between a GPS receiver and FTP server (via GPRS). For this purpose, there was used the programmable GPS receiver Telit, to which the Python script was uploaded, and its compiled version was run by the receiver on each start. The main task of the script was to send data, using NMEA sentences, to the file made in the real time on the selected FTP server. In the next step, the received file was appropriately formatted and transferred to the database on the server, which may be performed by any internet browser. After this stage, the user can see up-to-date navigational data on a website and choose the needed angle of characteristics. Software was also made for choosing and converting data to the CSV format, which helps to find the needed information in a file. (…)
