Good luck to the ANSR-87 launch team tomorrow!

We're launching TAOrem-3 from near Knoxville TN in late afternoon, and
welcome monitoring. The flight path will probably be northeast (see
attach simulation from 2 days ago).


*Past and future students and amateur astronomers are invited. Launch of
this remote sensing balloon is planned for 4 PM on 1/17/2015 from
Tamke-Allan Observatory in East TN, USA, 35.8325 Lat, -84.618 Lon.
Transmissions are 110baud ASCII, 8b, 2s, np on 433.97462 MHz upper
sideband, with ID WA4ADG-1 as announced on
http://arhab.org/hab_launch_list.php and on http://www.roanestate.edu/obs
and***tracked* on Twitter @TAOrem so please contribute observations.

Our 2 launches of 2014 used instrumented weather balloons (monitoring
position, temp, ionizing radiation, solar insolation, etc.), and
attained about 100,000 foot altitude before bursting as expected.. This
is more experimental, using a 1/3 filled non-expanding bladder -- we're
hoping for constant-volume altitude stabilization at perhaps 30,000
feet. If the heat seals hold, then flight duration may be substantial.*
*This is an underfilled sealed poly balloon and we're hoping for a long
flight.

Cheers and 73 de David, N4HBO

Hi all,

Upgrade complete and everything appears to check out. We are now using
the new datasets. If you notice anything amiss, please do let us know.

Credit as usual is due to Daniel Richman who interrupted his last
evening before term starts to fix everything up.

Cheers,

Hi all,

Due to a scheduled upgrade of the NOAA/NCEP service that provides the
wind data the predictor relies on, there will be an unknown (but
hopefully short) period of downtime on Wednesday, around noon UTC.
With any luck the only effect will be the 06Z dataset remaining in use
longer than usual but no promises.

The upgrade adds an even higher resolution dataset which we may swap
to in due course, but it also moves everything else around and renames
several parts of the system we access. As such we'll have to upgrade
the predictor backend when the service upgrade is complete.

There are some more details on the upgrade (for those curious) here:
http://www.nws.noaa.gov/os/notification/tin14-46gfs_cca.htm

We'll update as the situation progresses.

Michael
 


Hello All!

I know we are not yet at GPSL 2015, but I would like to get facilities arranged and on the books here for GPSL 2016 at Pecan Plantation, Granbury, TX well ahead of time! If our hosting it is too far South for GPSL 2016, please let me know.

I'd like to schedule GPSL at a time that will avoid Field Day, the VHF Conference and Dayton of course!

Dates in 2016 to avoided?:

Dayton is May 20,21,22
Field Day is June 24, 25, 26th
Plano Hamfest: June 10-11
independence Day July 4th
Central States VHF Conference: July 29,30,31

Possible Dates for GPSL:

June 3,4,5 2016
June 17,18,19 2016
July 8,9,10 2016
July 15,16,17 2016
July 22,23,24 2016

Please let me know by 1/16/2015 what you would prefer, include multiple dates if a few options are good as well.

Again this is for GPSL 2016, not 2015! :)

Particles detected by tubes on ARHAB Flights

Michael
 


Hello!

At GPSL I remember a few people talking about using a couple of tubes, one stacked atop another to detect "real" [your particle here] particles. What were the intended particles to detect?

I gave a talk on High Altitude Ballooning to our local EAA group. This was one of the topics (types of payloads) and I could not remember what particles were being sought.

BTW, the local EAA group is very excited about GPSL 2016 (not to be confused with 2015) being here at Pecan Plantation / Granbury, Texas, even volunteering chase planes, hangars and help on the field!

Re: Which SPOT (or other satellite tracker)?

I couldn't agree more regarding that connector -- I"m baffled as to why their engineers chose that one. Yes, it's small, but overkill IMHO given the # of connections and signal speeds associated with the interface.

Hi Ted,


  I've developed an Iridium board with built-in processor, u-Blox 7 GPS and is based on the SBD-9602 Iridium modem. I haven't tried the smaller 9603 module yet since it appeared to be more difficult to mount to a daughter board than the 9602 and more difficult to attach an antenna directly to a board. I've flown my Iridium prototype on 30 missions and it works great. No altitude limits as long as you configure the u-Blox for Air mode and works once it hits the ground and you can customize your telemetry output. I use a helical antenna (more expensive than a patch) but it does allow the payload to transmit successfully to the Iridium satellite network even when upside down or in odd positions while on the ground.

  The processor on my board is programmable in Arduino format so can be easily configurable. I had a problem finding a replacement antenna as good as the Sarantel ones that were discontinued and that has held up my production release, but I have finally found a helical antenna that works as well and just got them in. I also just received my new PC boards and am putting together the first production board so will be offering these soon online after I test them out. It's a real shame that Sarantel has gone belly up....it really caused a lot of grief and delay trying to find equivalent antennas out there.

  I have written a program that takes the emails you receive from Iridium, parses that info and then plots it onto APRS.FI just like it came from an APRS transmitter.

There is a monthly subscription that is more reasonable than a Spot and allows you 12,000 bytes of free data per month which is more than enough for several ARHAB flights. I also use NAL Research for the subscription plan as they are the most reasonable that I could find.

 I will let you know when I finish up this new board and when it will be available.

I recently flight tested a Spot TRACE unit. It didn't work at all during the ascent portion of the flight and didn't start working until below 38k feet. However it reported every 5 mins during the final descent and also reported the final landing location. It's small and lightweight and reasonably priced. However it will not report altitude or any telemetry and won't work above 38,000 feet or so. The older Spot units also work but are limited in altitude and do not report altitude either. If you hack a Spot Messenger and pay the expensive message units, you can send reports in any format but I have not tried that one out since the Iridium was more reasonable in cost to operate. I can get about 2 to 3 minute updates on the Iridium board but for best cost effectiveness I usually set it up for 5 minute intervals. Oh, one more advantage to the Iridium system is that you can email a command TO the balloon payload and have it activate things or change the data updates.

Hello,

I'm considering joining the club and adding a SPOT tracker to the traditional APRS tracking devices I use for balloon launches.  Questions:

1.  I see a variety of SPOT devices, with the Trace ad Gen3 models looking most appropriate for balloon use.  What are you all using, and why did you choose that one?

2.  Is there any way to subscribe to the required SPOT tracking service for shorter periods of time than a full year?  I only expect to use the service occasionally. 

3.  Anyone using RockBlock (or another Iridium approach) as a SPOT alternative?

Thanks.

Rockblock is just the modem so you'll need to interface this with something. This is a much better approach that the SPOT as you can then utilise a GPS module that is known to work at altitude such as the Ublox modules and do fancy stuff like 2 way comms. Also you can sub on a month by month basis on this one. However you do need to design a tracker around it.

My thoughts on the Iridium...

I've created a board that integrates an Iridium 9603 with a 32-bit Cortex-M4 CPU and some other bells and whistles, works like a charm, but:

- The Iridium 9603 is much smaller (and lighter)  than the 9602 used in the Rockblock, but otherwise functionally identical. The connector used on the 9603 is very small, and very fragile. I wonder how will it would stand up to the rigors of normal handling not to mention the  post-burst chaos unless it's very well protected.  I've seen at least one or two connectors fail for no apparent reason.

- I wonder how well the antennas for these modules work unless pointed straight up?  Not a problem for regular use, but I've heard that some have developed custom gimbals to keep the antenna pointed  up.

- In my opinion, it's difficult to get more than 1 packet through every 2-3 minutes due to retries and timeouts associated with failed comm attempts.

- My carrier lets me cancel service at anytime, but it does cost about $20 to activate (Nal Research).

All in all, this Iridium technology is very cool, especially since it lets you do two way communication, and doesn't require use of the APRS infrastucture.

Feel free to contact me off-list if you'd like more information about the boards I've created.

Hi Ted,

1.  I see a variety of SPOT devices, with the Trace ad Gen3 models looking most appropriate for balloon use.  What are you all using, and why did you choose that one?

IMHO SPOT aren't suitable for balloon use apart from being a backup tracker to something else like APRS or RTTY. They don't work above a certain altitude so certainly aren't suitable as a flight tracker. I'm not familiar with the different models, the other thing to watch is they don't work upside down. 

2.  Is there any way to subscribe to the required SPOT tracking service for shorter periods of time than a full year?  I only expect to use the service occasionally.  

I know some people rent them out but this is in violation of SPOT's T&C's

3.  Anyone using RockBlock (or another Iridium approach) as a SPOT alternative?

Rockblock is just the modem so you'll need to interface this with something. This is a much better approach that the SPOT as you can then utilise a GPS module that is known to work at altitude such as the Ublox modules and do fancy stuff like 2 way comms.

1.  I see a variety of SPOT devices, with the Trace ad Gen3 models looking most appropriate for balloon use.  What are you all using, and why did you choose that one?

2.  Is there any way to subscribe to the required SPOT tracking service for shorter periods of time than a full year?  I only expect to use the service occasionally. 

3.  Anyone using RockBlock (or another Iridium approach) as a SPOT alternative?

Thanks.

Re: Transpacific manned balloon flight attempt starts tomorrow

The flight has been delayed.  The upper winds are not favorable enough to launch.  They are deciding whether they can wait at the launch site (the balloon is laid out but not inflated) or whether to repack everything and wait for another day.  Their overall window extends through about February 20th.
