I don't think they have thought about it. Leo and others (myself included) have spent a lot of time ensuring if we did enter air space of another country we did so comply as best we could with the radio regulations etc. For example Leo disables 70cms over China. However others may not be as careful and handing these balloons over to "millions" of people isn't going to end well.

Additionally terminating balloon flights either remotely or automatically is something that can be complex and prone to failure. 

Additionally I've yet to see any actual technical detail from Rockzip just lots of marketing fluff like "improve the lives of billions down on Earth" . Making these balloons is very labour intensive, I've seen nothing yet that would make me throw money their way.

Cheers,

Anthony M0UPU

Two high altitude balloon flights are scheduled for today and tomorrow.

Today (8/7): NASA's WASP/HYSICS is scheduled for launch at 1400 UTC.
This is a hyper spectral telescope payload. No amateur radio aboard.

Tomorrow (8/8): High Altitude Student Platform (HASP) is scheduled for
launch at 1400 UTC carrying 9 student built payloads, including
Embry-Riddle's EagleSat engineering model. This payload will carry APRS
and other engineering data transmitting on 436.500 MHz.

Both are expected to fly along the I-40 corridor to the West and may fly
as far as Kingman, AZ. Both should be visible for 100's of miles. Float
altitude should be about 125,000 feet. Upper winds to the West is
expected to be 50 kts.

I will give an update to the status later this afternoon.

Thanks Leo but it is your flights that are impressive.  aprs.fi makes it pretty easy to add overlays but you have to have a web server for it to fetch them from.

I did another prediction and it looks like M0XER-6 should hit Spain in a few days.  aprs.fi...  I obviously need to add some time markers to the overlays for your flights.

Re: New Flight Prediction Program [1 Attachment]

I have made a major update to the flight predictor program.  You can still find it here: http://www.s3research.com/tools/flightpredictorHere are the major changes. 
 
  • The weather data page is gone.  The program now downloads the wind data as it runs the prediction.  This means it will take some time to run long predictions.  Additional predictions done won't reload the wind data.
  • I have added more wind points.  It now uses 46 points from 1mb (150K feet) to 1000mb.  The interpolation between points has also been improved.
  • The above 2 improvements were needed to support floaters.  This is now working fairly well now.  I generated this aprs.fi overlay for M0XER-6 a little over 24 hours ago. So far it is under 100miles off the predicted path.  I think this is more from a stable balloon and weather than the prediction.  Here is another I did for M0XER-3 this afternoon.
  Known issues:
  • I wouldn't try to do a prediction over 100 hours (6000 minutes).  There are some memory issues that pop up if you try much more than that.
  • It looks like I have a boundary issue at latitude +180/-180 boundary.  At this point that probably only affects Leo.
  • I have had a request to be able to use your own weather data.  I haven't implemented that yet.
Give it a try and let me know what you think.  If you see something that needs to change or be improved let me know.

[Attachment(s) from Jerry Gable included below]
Over the past couple of months I have been talking with Keith Kaiser about doing a new flight prediction program.  We think it is to a point where we need to get some more people looking at it.  I still consider it Beta software but appears to be pretty functional.

Here are the key features:
  • Downloads a variable size portion of the GFS 0.5 x 0.5 forecast for the prediction.  This is 42 pressures from 10mb to 1000mb.
  • Create multiple predictions and display them on the same map (screen capture attached).
  • Load csv files of a flight onto the map as well.  Currently understands aprs.fi and findu.com export formats.
  • Displays altitude graph of the predictions and flights.
  • Movable "Ruler" that allows you to measure distances.
  • Upload a prediction overlay to aprs.fi (example the same as the attached screenshot: aprs.fi/#!kml=http...).
  • Support for short "Floater" flights.  Does not support longer  (>4 to 6 hours) because only one forecast time is included in the weatherdata.

There are still some things that need to be done but I wanted to get some opinions on the tool before I call it done.  The things I know that need to be done are:
  • There are very few checks on the data.  You can enter values that will cause problems.
  • It currently has issues on Android and IOS tablets.
You can find the tool here: http://s3research.com/tools/flightpredictor/.  There is a list of the overlays that have been uploaded here: http://s3research.com/tools/overlays/.  At this point the overlays are all my test cases.

If you try it let me know what you think, good or bad.

Re: M0XER-6 has re-emerged W of WA state

James Ewen VE6SRV
 

Wow, what a sad statement on the ability of people to look after their equipment, and to keep it in optimal operating condition.

As M0XER-6 crossed Canada, the raw packet feed was nearly spotless for problems. i-gates fed the packets heard directly from the payload to the APRS-IS stream. Rarely was a direct packet missed, with only an occasional digipeat seen before being gated to the APRS-IS stream.

Now that the payload has crossed the 49th parallel, and is flying over Wisconsin, we see almost nothing but delayed packets being forwarded to the APRS-IS by poorly maintained i-gates (and possibly KPC-3 KISS based digipeaters). The noise level of the delayed packets overwhelms the good packets to the point where the track is showing what looks like holes in the tracking due to Hessu's algorithm's attempt to sanitize the garbage it is being fed.

Findu.com doesn't try to correct these errors, and shows multiple backtracks of the path.

http://www.findu.com/cgi-bin/track.cgi?call=M0XER-6

We see lots more digipeaters showing in the used path because the delaying i-gates are feeding expired data into the APRS-IS stream long after it was heard on the air.

Due to delayed packets, we are seeing anomalies being reported, such as flight speeds of 884 km/h. This is simply due to the math calculations between an old long past position being updated with a newer, possibly current position report.

Unfortunately there's nothing that can be done from the source to correct these delayed reports. 

The only thing one can do is to fly with a no-hop path. This removes the possibility of digipeated packets from the stream. Only packets heard directly by an i-gate will be forwarded to the APRS-IS. This helps remove the possibility of some of the packets being heard by delaying i-gates, as well as the possibility that a KPC-3 KISS based digipeater delaying the packets.

Gang,

We launched a small 150g balloon with a 100g payload this past weekend, consisting of a cheap $8 "808" camera and one of Alan Adamson's (W7QO) Peach trackers in a plastic bottle. It reached a surprising 13,500m. We had filled it with a lot of gas to keep the flight short. It was windy that day.

Re: ARHAB record rules

Mike Manes
 

Hi Leo et al,

Records of the length of the actual path may not exist; e.g. M0XER-6
which "vanished" over Mongolia well over a week ago and which has
just today popped up offshore from WA state. The on-board log can fill
in the last 5 days prior to its reappearance, but who knows where it
traveled before that? So although the actual travel distance seems
to be the soundest criterion, a great circle or constant latitude path
length might be more reproducible. Then again, it's flight >duration<
that's really the key piece of the art here; yes, picking the right
altitude for best winds sure helps, but that choice favors the winter
in the N hemisphere rather than Leo's summer launches.

Re: ARHAB record rules

Mark Conner N9XTN
 

The GPSL list began about 14 years ago as a list for discussing, not surprisingly, the annual Great Plains Super Launch.  However, over time it has become a general ARHAB discussion list as many who have never attended a GPSL have subscribed to it.  I've suggested in the past renaming this list and starting a new list focused more strictly on the GPSL events, but the consensus at the time was to leave things as they are.

As far as the ARHAB records go, Steve is right that many of the records were developed well before the era of routine floaters.  Most of them were formalized (if you can call it that) around 2000.  Practically no consideration was given to the concept of an around-the-world flight as something we'd have to keep records for.  As usual, the innovators have outrun the "administrative" aspects.

It is probably time to revisit ARHAB record-keeping.  When this was done before, we started with one person's volunteer efforts (Ralph W0RPK), made a few tweaks, and then published them.  At that time, the hobby was fairly US-centric and focused on amateur radio hobbyists launching latex balloons.  Since then, there are many more academic launches, use of non-ham bands (either by choice or by regulation), floaters, very-long-duration flights, etc.  We have no organizing body (in general, "organized" and "ARHAB" are antonyms) so it may be hard to come up with a rules committee who have the time and interest that's acceptable to all parties.  

If we revisit this, I would suggest doing so in the (Northern Hemisphere) winter, rather than when everyone is also trying to prepare and launch balloons.  This should help participation and keep from being distracted with real-time events (like watching three balloons circle the earth).  Certainly interested parties should make notes and draft a rule set that can be applied.

First let me say this is in absolutely no way a criticism of Keith or the ARHAB work he does - which is an outstanding effort and quite difficult negotiating in what can be a highly emotive area.

I do have a couple of axes to grind here:
a) There seems to be an implicit assumption that ARHAB is somehow part of GPSL or visa versa (else I’m not sure why we are discussing this here). 

b) the current ARHAB process seems to be publish first and then sort it out if someone complains - particularly with reference to the ITLAC01 debacle.   I think at a minimum 1st place record claims (particularly altitude / distance / duration) should have a pier review before publishing. 

Iv’e suggested rule changes before and the reply was - we can discuss that at the next GPSL.    Hummmm - see point a)

My 10 pence worth: Great circle distance isn’t a very good metric for long flights - it certainly isn’t proportional to the technical achievement. Developed at a time where up-down flights were the norm I suspect.  Also not clear how to apply it to multi lap of the earth flights.

SABRE-21 meets a watery end.

Bruce Coates
 

Hi

On Saturday we finally got a nice a day to launch SABRE-12.  There was thick fog at 7:00 but that quickly dissipated after the sun hit it.  The flight went without any significant issues although we didn't reach or goal of 100,000 feet.  The real problem came at touch down.  It's been a wet spring an summer in Saskatchewan so there are lakes, sloughs and puddles where they haven't been for years.  SABRE-21 found one of those.  It was only about 200 yards across but our payload landed right in the middle.

In 2008, when we started flying, Bob, VE5RGM (now VE7RGM) brought along an inflatable dingy.  When he moved to BC he left the boat behind.  We've taken it on every flight and this is the first time we needed it.  Thankfully it still held air.  Also thankfully one of the engineering students from the university volunteered to captain the little craft to rescue payload.

Some of our payloads are water proof and others are not.  We're still not sure of the final damage.
