GPS Panel is a simple web application to present information from your GPS

GPS Panel

GPS Panel is a simple web application to present information from your GPS. It depends on gpsd daemon, which reads raw data from your GPS device.

Installation

GPS Panel is based on Python Flask micro-framework. It has a built-in webserver and by default listens on port 8625. Install the pre-requisites:

$sudo pip3 install -r requirements.txt 

Copy the gpspanel folder to DIRECTORY (eg. /var/www/)

Usage

The GPS Panel can be run as a standalone server. It can be started manually by invoking python:

$ python3 DIRECTORY/gpspanel/gpspanel.py

Then using your favorite web browser, go to http://your_ip_address:8625

Auto Start

To enable the GPS Panel to automatically start after a system reboot, a systemd service file is provided for your convenience:

[Unit]
Description=GPS Panel
After=multi-user.target

[Service]
Type=idle
User=nobody
ExecStart=/usr/bin/python3 DIRECTORY/gpspanel/gpspanel.py
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

The above service files assumes you copied the gpspanel directory to DIRECTORY - replace DIRECTORY with real path to gpspanel on your system.

Copy the gpspanel.service file to /etc/systemd/system:

sudo cp gpspanel.service /etc/systemd/system/
sudo chmod 644 /etc/systemd/system/gpspanel.service

Now configure systemd to load the service file during boot:

sudo systemctl daemon-reload
sudo systemctl enable gpspanel.service
sudo systenctl start gpspanel.service

After startup, check the status of the GPS Panel service:

sudo systemctl status gpspanel.service

If all appears OK, you can start using GPS Panel using any browser.

Testing

To test GPS Panel while you don't have your GPS connected you can use gps_test.log. Just run gpsfake in your terminal to emulate gpsd service:

gpsfake -c 1 gps_test.log

gpspanel's Issues

Visible satellites list get into signal strength graphics

Looks like there must be limit in displaying visible satellites list. Maximum number not getting over graphics is 13

Add a default empty image for GPS signal chart

Hi,

I am using gpspanel in astroberry.io, and when there is some issue when loading GPS data, the panel shows a broken image on the signal panel.

I suggest adding an empty transparent image, by substituting this code

gpspanel/templates/main.html

Line 225 in bbae6b8

<img id="sschart" src=""/>

And using this new code:

         <img id="sschart" src="data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs="/>

socket.io Bad Request

Hello,

I'm trying to use gpspanel in a personal project to monitor GPS status. Im using Raspberry Pi OS (32 bits) on a Raspberry Pi 4.

After installing requirements I tested as is suggested. I ran the following commands (in different shells).

• gpsfake -c 1 gps_test.log
• python3 DIRECTORY/gpspanel/gpspanel.py

In last console I get the following message
$ python3 gpspanel.py The client is using an unsupported version of the Socket.IO or Engine.IO protocols (further occurrences of this error will be logged with level INFO)

When I open the web I get the following errors in console (both in Chrome 103.0.5060.114-64 bits and Firefox 104.0-64-bit over ubuntu 20)
socket.io.min.js:1 GET http://allsky.local:8625/socket.io/?EIO=3&transport=polling&t=OBgF61P 400 (BAD REQUEST)

I will appreciate some idea to solve it.

Best regards,
