I was balls-out on the hamfest all day (chair).  Never actually saw the hamfest, but I did go out and see the balloon directly overhead.  Folks were going to tune into the UHF APRS, but have not heard reports.

 

Looks like it went well for you.  Congrats on another success.

HASP Flight Complete, Recovery Today

Jack Crabtree
 

The 2014 flight of High Altitude Student Platform (HASP) is complete. After attaining a float altitude of 125,000 feet for 5.5 hours, the payload was brought down North of Winslow, AZ. The 1800 lb payload was launched from the Columbia Scientific Balloon Facility in Ft. Sumner, NM using a 11.8 MCF zero pressure Raven Aerostar balloon. Recovery of the payload will occur today after coordination with the Navajo Nation. See http://towerfts.csbf.nasa.gov/Maps/ConvGps649N.htm for the actual flown flight path.
 
Embry-Riddle Aeronautical University of Prescott, AZ flew one of the 9 student payloads aboard the HASP flight. This payload consisted of an engineering model of the school’s EagleSat, a 4 inch cubesat spacecraft scheduled to be put in orbit in late 2015. The half watt 70 cm communications subsystem provided telemetry and APRS position data throughout the flight with the call sign of N7ERU. Commands were executed via the comm system from the ERAU campus ground station at up to 300 mile distance.
 
Thanks to those who provided reception reports and even one visual report during the flight.

Web Site Renewal and News

Keith Kaiser, WA0̷TJT
 

Aeronauts,

OK for all you nervous types out there, the ARHAB.org web site domain and hosting has been renewed for the next 6 years thanks to the generosity of the following;

Charles Goldsmith
Daniel Wietchy
Douglas Hanson
Bruce Coates
Anthony Stirk
Steve Daniels
Keith & Deb Kaiser
California Near Space Project
If I forgot someone please let me know so I can acknowledge your contribution to the community.

I want to thank the people and groups who offered to host the system. After discussion and looking at the history of many other web pages I made the decision to stay with an independent (from the HAB community) and commercial solution for hosting. GoDaddy does all the backups and site protection on a massive scale as well as offering many other services, making this one less thing to worry about.


In other news:

If you have not had a chance to check out the new flight prediction program at; <http://s3research.com/tools/flightpredictor/> I encourage you to take a look. Jerry Gable has made a wonderful contribution to our hobby. Some of the key features include:  
  • Downloads a variable size portion of the GFS 0.5 x 0.5 forecast for the prediction.  It uses 46 points from 1mb (150K feet) 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 weather data.
  • and more..
Jerry is constantly updating the program with new features so keep an eye on it.

Re: Fw: Arizona Near Space_Rockzip

Anthony Stirk
 

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.

Re: New Flight Prediction Program

Jerry
 

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]

Jerry
 

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.
