Sledgehammer

This is an update on the ADS-B device. I have written about this in the previous two communications, here and here. So, on Tuesday 2nd August the Raspberry Pi arrived. Since then I have been setting it all up so the receiver is no longer dependent on the PC being on.

 

The first thing was to install the correct OS on the Pi. The picture shows it in initial phase with monitor, ethernet, keyboard and mouse all connected. Once the OS was installed I had to tell it to not load the GUI and just run a command line. Then, I got it connected to the network and pretty much removed all the cables apart from power.

I can connect to the Pi using SSH and run script from the command line. Next phase was to load the USB stick drivers and software. This was reasonable. Next up was the ADS-B reading software, installing and getting it running seemed easy enough and then I had to adjust some code to make sure this service starts up from boot. Next software to load was the MLAT server program, this was easy enough although initially I couldn’t quite find the correct code to check it was running.

Then, the whole set up was tested in the dining room window.

Today has been the task of moving the unit to the loft. I didn’t have any power sockets up there so one had to be installed and that took the time! Once that was done the system just needed to be secured onto the main beam in the loft. The important thing is to keep the length of the cable from aerial to dongle as short as possible, this increases the signal going into the Pi. The loft set up has been tested and it is running fine.

I have access to the Pi either via the PC using a program called PuTTY or the iPhone using an SSH connection. I can shut down the Pi remotely and monitor the internal temperature of the device. It is running at a range of 50-60 Celsius. Using a Pi to run this software is a bit like taking a sledgehammer to a walnut. But, it is independent and runs remotely. I am happy this procedure was reasonably straight forward!

The next stage is to get a more specialist aerial and maybe a more specific USB Dongle. However, this is one of those things where the amount of money you spend can be unlimited. You know, I could just install a radar up in the loft. However, here is the current splat for the range of the aircraft from my ADS-B receiver.

Now that I’ve been reading a bit more about this type of thing I can explain a little more. ADS-B is broadcast by many aircraft and they send this on 1090MHz. These are the signals I receive in the loft and can see on my Virtual Radar Server software. I also send these signals over the internet to a new “radar” website. The ADS-B signals contain bits of information about position and heading, these are sent to a server which can determine positions of other aircraft by using time differences between signals arriving, this is called MultiLateration or MLAT. My Pi is part of this network allowing Radar360 to “see” more aircraft than just ADS-B alone.

ADS-B

I’m interested in aircraft. I don’t know why it started but it’s pretty much always been there. I grew up near Stansted airport and I can remember seeing the Space Shuttle visit in the early 80s, I saw the 747 and Shuttle circle around from the primary school playing field. When I studied art at secondary school every picture of mine contained an aircraft much to my teacher’s annoyance.

Nowadays it’s easy to see aircraft on the web. I have the planefinder app installed on my phone and often tweet when I spot an A380. I only really tweet the A380 as it’s massive and extremely beautiful.

My aircraft thing also meant I travelled to Stansted to see Air Force One take off a few months ago.

I wanted to find a way to see what military aircraft are doing in the skies and I found a website called 360Radar who have this information. The site isn’t open to public yet and I emailed to see if I could get a test account. They said yes.

I like the site. I like the filters and information that I can see. This site relies on people sharing their MLAT data with them and they will offer a free account if you share data. They have a great comprehensive guide to setting up a system that is currently here. I ordered a small aerial and it arrived today. Within about thirty minutes of getting to the computer I was running the data server and sending information to the network.

I have a USB aerial picking up 1090MHz signals from aircraft. I then have a small program running to collate that data and form it into useful data.

Screen Grab of ADS-B Signals

You can see that I am picking up an aircraft over Cherbourg which I think is quite impressive. All of my aircraft are south of my position because my aerial is placed in a south window. I will look into moving the aerial to a more central, higher position in the house so that I can pick up aircraft all over!

Here’s another screen grab of the output from my aerial.

How it works

Many aircraft broadcast position information on 1090 MHz. This information comes from the aircraft’s navigation system but does not require the pilot to be involved in the operation of the system. The position of the aircraft is determined by GPS. This output information is called Automatic Dependent Surveillance Broadcast. My little aerial picks this up and reads it. My computer then sends this information to a website which aggregates the information.

For aircraft that don’t output the ADS-B signal their position and direction can be known using multilateration [MLAT]. This involves two or more base stations and measuring the time difference between each station receiving a signal. It’s very clever!

Not A Thing

I should have learnt by now. I really shouldn’t look. But sometimes it’s a handy way to kill twenty minutes. I glance over the headlines of the Daily Mail online to see what crap they are infecting the populous with these days. I saw this:

dailyfail2

Please click on the picture to read more if you want but trust me, it’s propaganda and mostly an advert for an online ancestry DNA company. It also doesn’t tell you anything about your own ancestry.

Up front I should tell you that I have big issues with nationality and pride in our country. I don’t even understand why being born somewhere makes you different to people born in other places. I don’t understand good old British values. For instance, Leonard Da Vinci was born in the Republic Of Florence, but we would describe him as Italian if we wanted to. So where you were born has no influence on the nations that will rise after you and claim you for themselves.

This Ancestry company takes a swab of your DNA and then compares common components of it with that taken from people around the world. This is bullshit. They compare your DNA with that of people living now in other countries to see what you share. That’s what you share now. In this time. Not what you share that’s from a common ancestor. It doesn’t tell you about your “racial” or “nationality” make up. It tells you that you have a common ancestor with people in another country.

EVERY modern European is descended from Charlemagne. Go back far enough and everyone has a common ancestor. Someone having children 2000 years ago has contributed to the DNA of virtually all Europeans.

There is no such thing as race. There is no such thing as nationality.

Now, let’s get to the headline.

Saxons

The Saxons are from Germany. Saxony. In Germany. Or rather in what is now Germany and wasn’t Germany for many many years.

Angles

The Angles were from what is modern Germany. It’s why we are called English. It’s why the French talk about Anglais.

So, there are no British people. Just people who happen to be born on the island of Britain at some point in time.

Fuck the Daily Mail.

The Jungle Book

Busy cinema week for me I guess. Took another trip to Cineworld, Rochester. This time to see The Jungle Book. I rated this on IMDB, always look at this communication to explain the system I use.

I have to say that I hadn’t seen the other films. I knew the songs but most Disney stuff is not on my radar. There are many “classics” that I just don’t know. I watched some Disney films over the last year but I wasn’t really that impressed.

This film looked bloody gorgeous. It was worth seeing just to marvel at the animation. The animals are spectacular. It was brilliant.

The story was largely dull, not really something that I thought was brilliant. I was concerned that the animals seemed quite happy to forgive their jungle being burnt down. The overall story is that man is superior. So sad really. Humans may be in charge but we are also fucking the planet over rather well. Sod all this Brexit stuff, we have a much bigger problem to work together and minimise but the current political system won’t allow that.

I was really impressed with the Apocalypse Now! references and I wanted to laugh out loud but I don’t think that would have been understood!

I wasn’t that surprised that some of the songs were kept in the film but would rather they weren’t. Although they may have been the only songs in the animated film, I don’t know, I’ve not seen it.

Kentish Garden

Took a trip out to Sissinghurst in deepest darkest Kent. It’s a National Trust garden and although billed as a Castle Garden, there wasn’t much of a castle.

It was a nice few hours spent wandering around and see stuff. As someone who isn’t that bothered by plants I guess some of it was lost on me at a deep level. There were plenty of people stopping and smelling and touching the flowers but I didn’t. Yes, they look nice but I’m just not interested.

Here’s a gallery of green.

On a walk around the lakes there was a little door in the bank. How strange.

There did seem to be quite a few German visitors and this pleased me, the Germans coming over and spending their money, although granted it’s not as much money as before the referendum.

Kent Views

Not a great deal of writing with these. Here’s Maidstone bridge over the Medway.

Here’s another Medway bridge this time it’s for the M2 and railway (three bridges really).

Now a picture of a lavender field. There’s another one next to the A229 and from the corner of my eye it looks like an uphill lake!

Finally, here’re some boats, just because.

The Legend Of Tarzan

I went to the Cineworld cinema at Rochester to see The Legend Of Tarzan. As usual I have rated this film on IMDB and if you aren’t sure of my rating system then you should see this communication.

I thought the film was enjoyable. A good romp with those pesky colonial Belgians in charge. I was largely impressed with the CGI animals, very impressive and realistic. The story was ok but nothing special. My one quibble would be with the physics of swinging on vines and catching a train doing so, simply unrealistic, but a minor infraction for this particular film. I guess I should read the book.

By the way, the first corner at Zandvoort race track is called Tarzan. It is named after the man whose garden was used to create that part of the track.

New Wheels

Consider the state of these:

Tatty Trainers

I thought it was time to change them. I think I’ve had them for about 2 years and so they have probably done around 1000 miles! So I bought some new trainers. These ones are nice and bouncy!

Shiny!

Let’s see how long these ones last!

For God’s Sake Man It’s Only A Weather App

I recently saw that the Met Office had a new weather app. I think it popped up on the front page of the app store. I was interested as I’m quite fussy about my weather apps. Once you get used to one and the information it gives you it’s quite hard to change. Much like buying a new wallet, which I have to do soon and it fills me with dread. By the way, I don’t like the term “app”, I’m not particularly fond of the term “application”, to me these are programs and always will be.

Here’s the front page of the new app:

The new app had embedded video forecasts from the Met Office – these are not needed, I’m too old to care for video forecasts. Also, video on a phone is antisocial and useless, I can get the same information without the noise and movement. I think this may be a generational thing. I don’t need sound and people to inform me something that I can see in a diagram or map. It could possibly be why I also don’t like the news that is broadcast into our homes all the time [hint: change channel, which I do].

 

Here’s another view of the new app:

I’m not sure I like the days across the top. I think that’s mostly because I the older app [which is still available] had the days going down the screen. The worst part of the new app is the weather alert screen. This screen used to be a map with colours over it.

This is a good weather warning map. It tells me what I need to know. The new app just has text to read. I can’t be bothered to read it. The text is broken down into regions. I can be even less bothered to find my region and then decode the words. Oddly, I do like listening to radio weather broadcasts so maybe I’m just weird here.

One last thing. The new app has done away with proper weather charts. These actually mean something to me and I like them. They give an overall impression of what is really going on in the weather. Here are some examples of good stuff:

Day by day and then lovely extra information if you need it. There’s a page that will give hour by hour predictions too.

Look at these maps. Aren’t they pretty and lovely. They let you know what’s going on. The new app doesn’t have this. Which is a shame. I do get the feeling that sometimes things are “improved” to include lots of new functions but the reality is that they just fuck them up.

CCF Camp WITT

I recently spent a lovely week at RAF Wittering [EGXT] with the MGS CCF RAF Section. We were there with cadets and staff from Malvern College who all turned out to be great people. In fact, their Officer Commanding had been on my OIC course.

Harrier Fun
Harrier Fun

Here’s a list of activities we got up to followed by a small photograph gallery which could have been bigger but sometimes there are restrictions on what we can photograph.

  • High ropes course and power fan
  • Archery
  • Air Experience Flying with No 5 AEF
  • WHST
  • Shooting with the L98A2
  • Drill and drill competition
  • Command Tasks
  • Visit to Marshalls Aerospace Company
  • Visit to the American Cemetery near Cambridge
