Dear Friends,

Just a stupid question about network security before ordering a probe:

Did you implement network security against hacking the firmware?
Is firmware publicly available and Free software?

Kind regards,
Kellogs

Dear Friends,

I am new here and first and I would like to congratulate you for the BlitzOrtung project. There was lightning in my area in France and I just discovered the project using Android BlitzOrtung project. It is great to see such a well-organized community project.

So my question is as follows: there are Billions of euros lost in lightning every year. Still, a large number of areas are not covered by BlitzOrtung around the world.

There are similarities with other projects. For example ground based GPS (GNNS) and differential GPS (RTK). Differential GPS are precise GPS stations providing positioning data. Some GNSS stations are located remotely in noise-free areas all around the world. And all of them have Internet access. Most of them are run by scientists, for example in observatories or meteorological labs.

Maybe ground GNSS stations would be interested to host a BlitzOrtung receiver. GNSS stations are usually organized in communities. So we know the precise positioning of each station.

Here is a partial map. In fact, there are way more of them:



Here is a list of station networks that could become partners:

EUREF Permanent GNSS Network
Based in Belgium.

All network is extreme quality.


In 2015, Africa had 54 ground-based GNNS stations:

Brasil: IBGE Brasil

Brasil map for GNNS with hundreds of receivers (I guess so, but I don't speak Brasilian):

French Guyana
Think about IGN or Arianespace.

Glonass stations (not official list)

or from ESA:

Do you think it would be valuable to list all possible GNNS stations worldwide and try to contact them? Some of them should have direct interest to install a BlitzOrtung detector, just for safety of equipment and protection against lightning.

Maybe this was discussed before, but what would be the perfect grid for precision reception?
Can you describe it? How many sites would you need in South America and Africa?

Kind regards,

I'm finding I'm getting exactly 100 triggers per second on the H field antenna and I think it's down to house wiring as turning it so that it's 45 degrees off parallel with the x and y axis of my house reduces the noise. The auto amplitude filter is effective and cancelling out +/-47 and +/- 141mV

Antenna is a coaxial möbius with a 50 turn transformer. Settings below. Any thoughts?

Antennas- My Blue seems to be working great but I was wondering if I should be using the E-field antenna with the H-Field antenna. At the moment all I use is the H-Field.

Mountains- I may be moving to Durango, CO in a few months (current system will remain here if I can get another Blue). Do mountains pose a problem for receiving signals?

All,

New to the forum but long time user of the Lightningmaps.org website. I have noticed, where I work, the lightningmaps.org page will show dynamic, real-time updates of flashes but the en.blitzortung.org page does not. It only does a full page refresh every minute. Are there different internet data flow requirements (firewall access, PC/browser setup, etc.) between the two pages? What does it take to make the en.blitzortung.org show real-time flashes like it does at my home PC?

Thanks in advance,
Jeff

Thank you for the project.  I have a sensitive 11yr old daughter that has been both fascinated with weather and astronomy.  The live maps have helped her understand and feel more secure when storms run through our area. We have used the live map on the tv via chromecast to keep an eye on when things are getting close so they are not as much as a surprise.  

Its a really neat way of "seeing" the lightning via RF and triangulation.  It some what ties into the idea of how geocaching works so it was easier for her to understand. 

She would like to become a contributor to the network even though she fully understands our lone detector would not be a huge advantage to us as an individual but would make the network better in our area. 

Keep up the good work.

How do I find the status page in the controller so I can get the "Device ID"  and then log in and get an account?

I'm trying to track down an intermittent interferer that is being picked up by my H-field antennas.

The trouble is that I have no way to be notified that the interference has return unless I just happen to be by the unit or logged into the units webpage.

Am I overlooking a was of having the unit notify me somehow so I can know when to start my troubleshooting?

Thinking about antennas, before I have the system:

How far away from the top power line (residential street HV to the pole transformer) do I need to be?  How much 60 Hz rejection does the Blue system have?
