High altitude balloon Christmas wishlist 2015

This year we have 2 items to add onto your Christmas gift wish list but, given the price tag, direct these too your wife/husband/partner and not your children.


By far the best bang for your buck this year is the 4GEE camera by EE. The Go Pro style action camera has two key features that HAB enthusiasts will like. The first is the ability to easily stream launches online; which  is quite unique amongst action cameras. You can also interchange your phone and camera sim card to share the data allowance and avoid having to have two separate mobile phone accounts.


Second is the camera performance. The camera battery performs well beyond the 3 hours specified by the manufacturer and will often exceed most simple ‘up and down’ high altitude balloons flights. While the camera is limited to producing video at 1080p, the storage demands for 2K and 4k images currently preclude their use for HAB many flights.

The camera is a little heavier than equivalent Go Pro cameras but we still recommend you ask Santa Claus for one of these.

The 4GEE camera is £299.99 to buy outright or £17 per month with data.

Flight computers

If you would like to move your tracking to the next level complexity then we suggest a ‘Pi in the Sky’ board or PITS for short. The PITS is a radio tracker and SSDV imager based on the successful Raspberry Pi computer. The PITS offers you the ability to radio track (or have others track) your flight from launch, to balloon burst, and landing (or close to it).  A step by step guide offers a relatively easy scheme to set up the board, listen to it using a radio and computer, and to put the trackers location on an online map. The only difficulty we found with using the PITS is decoding the radio signals using a programme called DlFl digi. But with some practise and, for us, 5 days of our time, most groups should be able to get it up and running.

The PITS board itself costs about £130 but this is just the start. You also need to budget for a Raspberry Pi, a suitable real radio or computer based radio, antenna, desktop or laptop (which you obviously have), and a Raspberry Pi camera. You also need to be able to make your own antenna for the PITS board…. but what are boxing days for!

Fun Challenges of Radiosondes

What is the cost of using a Radiosonde?

Who can I contact for more information?

WHAT:radiosonde Conduct scientific ballooning campaign using radiosondes from multiple locations across the 8/21/2017 total eclipse path, from Oregon to South Carolina. These balloon-borne devices provide basic atmospheric measurements including temperature, relative humidity, wind speed, wind direction, and pressure. The eclipse gives us the opportunity to conduct the largest geographic campaign of balloon flights ever undertaken. The focus on increased spatial and temporal resolution of data for scientific and forecasting purposes is extraordinary. With cross agency collaborations we have the potential for this to be the largest geographic radiosonde campaign ever undertaken.


  • Public engagement. Total eclipses are rare and very impactful events. For those who have witnessed them, it is a memory they keep forever. The continental US hasn’t had a total eclipse since 1979 (northwest only). The NASA Space Grant network is in a unique position to engage the public in an awe-inspiring and educational way at a surprisingly small cost.
  • STEM pipeline development. Conducting radiosonde flights presents an amazing hands-on learning opportunity for students. Participation in these launches encourages students to follow STEM paths through college. The engaging STEM content resulting from this project is not limited to the timeframe immediately following the launch, but introduces a permanent dataset that can be analyzed by students, extending the impact of the flights to future classrooms as well.
  • Partnerships. We will develop several potentially long lasting partnerships with other federal agencies and with industry; an effort we hope will include a broad range of leveraged assets.

WHO: 150 teams consisting of partnerships between university and pre-college programs is the goal with a dozen teams already lined up to participate should support be available.

WHEN: Eclipse totality starts on the Oregon coast at about 1:20 PM Eastern on August 21, 2017 and ends about 2:50 PM Eastern on the South Carolina coast.

WHERE: Teams will be coordinated with both the large balloon launch sites and surface mesonets (mesoscale network environmental monitoring stations).

Project milestones:

– 2015: Fundraise, organize, and select participants

– December 2015: Distribute radiosonde systems

– July 2016: Hold workshop on best practices of data collection

– June 2017: Hold dry run with at least one flight per location

FUN CHALLENGES: While radiosonde launches are done twice daily by the National Weather Service, carrying out a coordinated network of such flights among academic institutions from across the country presents a few challenges. These challenges are broad – technical, political, administrative – but provide interesting training opportunities for the student participants and make the project exciting and very worthwhile for the participating teams. Challenges include: precise timing of the launches for temporal resolution targets, collaborating with groups of mentors and students at locations spread across the country, making the necessary arrangements with NASA so that the data can be linked to the NASA eclipse (or main) web page, developing the infrastructure for data analysis by the undergraduate students, and developing the curriculum for the 7-12th grade students to be utilized after the event.http://gps-tracker-review.toptenreviews.com/index.html</p&gt; <p>The web page ‘Top ten Reviews’ has done a partial review of some GSM/GPS locators on the market.

The exception is the Garmin GTU 10 which is just an annual contract service. The Loc8tor company (http://www.loc8tor.com/uk/ ) is discontinuing the ‘pay by message’ service and moving all of their clients to a pay by month service. Often HABists will only use as little as 10 location messages per flight, which makes the Garmin and now Loc8tor trackers an uneconomical option for HAB.

Here’s the flight track (click on the pic for a bigger version).</p> <p><i>Geronimo</i> itself was packing a Garmin GTU-10 tracker and a Tiny-Trak TU-601 APRS. The latter “initially gave a correct reading prior to launch and then gave anomalous readings throughout the flight”, Professor Kissel noted.</p> <p>That wasn’t the only malfunction the plane suffered. Kissel said: “Somewhere before or after burst, we’re not sure, the nose cone of the plane fell off (it had been cemented on shortly prior to launch), and our two tracking devices fell out.</p> <p>“The Garmin GTU-10 landed unscathed, gave off its signals at low altitude as intended, and was picked up north of Carmi, Illinois shortly after the other pods had been recovered in Indiana.”</p> <p>Jack Sweet was the lead of the paper plane tracking device team and has given an overview of using the Garmin GTU. Jack said, ”  Initially it was believed that we only had to log the release of the paper plane with a time stamp and altitude with the help of an APRS TU-401.  Once the guidelines were received from Guin., it was found that we had to track the entire accent and decent of the plane.  Thus, we had to switch to a different form of location device and place it into the plane.  The selected device was an APRS TU-601.  We also included the Garmin GTU-10 for redundencey.   To begin, I will give you the pros.</p> <p>Pros:</p> <p>The price of the unit used was approximately $200.00.  Included with the purchase, a 1-year subscription to the service was included.  In  addition to the baseline service, we also purchased the Deluxe Tracking Package for $4.99.  This Deluxe package allowed the unit to enter a continuous tracking mode in which the user could define a time interval in which the Garmin would transmit location continously.  The unit performed as needed when on ground level.  The Garmin could transmit the position to within 15 feet of actual location.  The unit also has an app for ISO and Android devices to allow tracking capability for anyone with a smartphone.  Battery use of the unit was incredible.  No problems there.  The simplicity of the device, having only a power up button, left little room for error.</p> <p>Cons:</p> <p>Once the unit reached an altitude of 8,000 – 10,000 ft, it failed to transmit its location.  Once the unit fell below this threshold on the decent, the Garmin reestablished transmission and the team could locate the attached equipment.  The Garmin also does not offer a way to export the data in manner to be recorded.  This kept the team from being able to plot the line of travel of the balloon.  In addition, the data is only stored on Garmin’s website for seven (7) days.  This put a time constraint into the equation in which the team had to gather as much data as possible to recreate the voyage.</p> <p>In conclusion, the device is great if it is only intended to  locate an item below 8,000 ft with no available data.  If data is needed up to the point of release or burst, the unit is not recommended.  Overall, I say the unit did exactly as it stated.  It is strictly a locator, not a tracker.  If you have any other questions, please feel free to email me directly at this address.  If you could also include a link to your article about this item, I would enjoy reading it.  Thank you very much for taking interest in our attempts. ”</p> <p>For more information go to https://sites.google.com/site/usihab2011/home</p> <p>Another project using the Garmin GTU 10 can be found at <a href="http://www.bertha2.com">http://www.bertha2.com</a></p&gt; <p>According to the US Garmin web site, the Garmin GTU 10 only works in mainland USA. <a href="https://buy.garmin.com/shop/shop.do?pID=67686&amp;ra=true">https://buy.garmin.com/shop/shop.do?pID=67686&amp;ra=true</a&gt;, however it has been used in HAB flights in Scandinavia.</p> <p><em><strong>Solution to a frustrating glitch for some CattraQ users</strong></em></p> <p>23rd October 2012</p> <p>Caitlin Knight from Australia found a glitch in the CattraQ operating system. She found that after initializing the devise with her mobile number, she could not get a location from the devise; just an acknowledgement that the sms function was ready. Caitlin said, “I recently purchased the CatTraQ Live 3 model and have been trying to test it for possible use in a research project i will be conducting, however when I program it using my phone I am getting messages like “Autrhorize okay” “Sms okay” “Loc okay” “Link okay” but am never actually getting any output in terms of GPS locations and I have no idea why.”</p> <p>Mr Lee from CattraQ said, “After checking back with software development the problem is that the authorized number does not match the number of the incoming call. This can happen for example if you authorize your phone number in international format like +44321556677 but your phone provider is just transmitting the local format 0321556677. Please check if that’s the case.</p> <p>If there is no match of the incoming callers number with the authorized number, then you will get an acknowledgement but no coordinates.”</p> <p><em><strong>Comparing Enhanced GPS trackers</strong></em></p> <p>updated 19th October 2012</p> <p>Posted by Chris Hillcox</p> <p>There are now a range of enhanced GPS trackers on the market so it would be useful to compare what is out there.</p> <table border="1"> <tbody> <tr> <td>Unit</td> <td>Weight Inc battery (g)</td> <td>Dimensions</td> <td>GSM Band</td> </tr> <tr> <td>Cattraq Live3</td> <td>44g</td> <td> 50mmx42x23mm</td> <td>Quad band</td> </tr> <tr> <td>TK102</td> <td>60g</td> <td>195mm x 130mm x 60mm</td> <td>Tri Band</td> </tr> <tr> <td>GT30B</td> <td>70g</td> <td>76.0(L) X 45.0 (W) X 16.0(H) mm</td> <td>Quad band</td> </tr> <tr> <td>Pingme</td> <td>32g</td> <td>60x35x13mm</td> <td>Tri band</td> </tr> <tr> <td>TK203 Fordex</td> <td> NA</td> <td>70mm x 43mm x 17mm</td> <td>Tri band</td> </tr> <tr> <td>Loc8tor pet GPS</td> <td>60g</td> <td>66mm (H) x 36mm (W) x 20mm</td> <td>Quad band</td> </tr> <tr> <td>Track Pod 2</td> <td>58g</td> <td>65mmx35mmx20mm</td> <td>Tri BandQuad band upgrade available</td> </tr> </tbody> </table> <p>TK102 is made by Xenun Inc of China. The unit has a cool feature in that it includes a google map link in the sms message. It is a real value product but is only tri band so don’t use it if your payload may drift over to the continent; intended or otherwise (http://www.xexun.com/ProductDetail.aspx?id=102). At the time the review was written, TK102 was available for £40 from Amazon.co.uk.<strong>*Warning* Many pirate copies of TK102 are available on Amazon and they come with very poor quality lithium batteries which obviously pose a safety risk.</strong></p> <p>CattraQ Live3 is made by Mr Lee Enterprises in Germany/USA (http://www.mr-lee-catcam.de/ct_index_en.htm). CattraQ 3 is a big improvement on Cattrack2. It has the standard sms tracking function as well as a live tracking mode using GPRS data networks. The unit also takes a 2gb micro sd card to record positions during flight. The sms location message as been improved to include a google map link. All of this, and the unit is less heavy than Cattrack2 at 44g. Cattrack can be bought from the manufacturers web site and costs £73.</p> <p>GT30B is made by Smart Tracker. Like the TK102, the cool feature of this unit is the google map link to the tracker location. The unit also has quad band function. Unfortunately it is on the heavier side of the range of trackers. At the time the review was written, GK30B was available for £68 from Amazon.co.uk.</p> <p>Pingmee   is made by Defuturo Ltd  (http://www.pingmee.co.uk/). The cool thing about this tracker is it’s weight. It is half the weight of comparable trackers due to the battery type. I have no data on battery performance which is a critical parameter. It also has a tracking web page and has UK based customer support. At the time the review was written, Pingmee was available for £65 from Amazon.co.uk.</p> <p>TK203 is made by Fordex. This unit has little to shout about. It is expensive and has only tri band function.</p> <p>Loc8tor pet GPS (http://www.loc8tor.com/uk/primary-products/loc8tor-pet-gps.html) is comparable to the Smart tracker and Cattrack. The big difference is the price tag at over 200 pounds. The unit does come with a free case and tracking web site but I cannot see and cool feature that justifies this price.</p> <p>Track Pod 2 is distributed by Track Shop UK (<a href="http://www.trackershop-uk.com/TRACK-Pod+2+LiveMap+GPS+Tracker-p-59.html">http://www.trackershop-uk.com/TRACK-Pod+2+LiveMap+GPS+Tracker-p-59.html</a&gt;) . It’s functions and mapping extras are broadly comparable with loc8tor. Also, as with loc8tor, there is no option to use a mobile phone simcard. The ‘credit’ on the tracker is topped up on the tracking web site. The basic unit costs £159 though does come bundled with 100 position credits and 25 command credits. Interestingly it has a sleep mode when stationary to save power and can be re activited by command.</p> <p>I short the TK102 wins on price and Pingmee wins on weight, but I do need more information on how it’s battery performs.</p> <p><em>Rogue data from SPOT Messenger 1</em></p> <p><em>20th April 2012</em></p> <p>Review posted by Chris Hillcox</p> <div> <dl> <dt><a href="https://balloonnews.files.wordpress.com/2012/01/spot-tracking1.jpg"><img title="spot tracking" alt="" src="https://balloonnews.files.wordpress.com/2012/01/spot-tracking1.jpg?w=300&quot; width="300" height="150" /></a></dt> <dd>Spot tracking with rogue data</dd> </dl> </div> <p><em>Today I assisted on a project by South Cheshire college to launch simple payloads on 1200g balloons.

Thankfully the rogue points were not during the landing phase. Spot is a great tracker but I am now mindful that if can have glitches.</em></p> <p>Here is what the operator of SPOT had to say, “The reason that point 6 is  “off” may be due to the fact that the gps tries to get a satellite fix for 3 minutes.  If 3 or more satellites are not in direct contact  during that time, it gives an estimate .  That estimate may not always be accurate.”</p> <p>CatTrack live 2 GPS – Assisted GPS tracker  <a href="http://www.mr-lee-catcam.de/pe_cc_o2_en.htm">http://www.mr-lee-catcam.de/pe_cc_o2_en.htm</a></p&gt; <p><img alt="" src="http://www.mr-lee-catcam.de/PICS/CTL_S.JPG&quot; /></p> <p>Review posted 7th Jan 2011 by Chris Hillcox</p> <p>The Cat Tracklive 2 worked very well and in line with manufacturers spec.

At 80 Euros it was also cheaper than competitors, like Loc8tor Pet GPS.  CatTrack live uses GPS and GSM technology to give you the location of the tracker during its approximate 48 hours of battery life. It is light weight, small, and uses standard pay as you go or contract sim cards (I used Orange) . In mission one the hand warmers failed and the payload landed in the Neatherlands but as soon as it was in mobile signal coverage, I was able to call the tracker and got a text message giving longitude and latitude. The trackers stand by time is 48 hrs (manufacturers spec) and I was able to use mine for something between 24 and 48 hrs with, during which I was able to contact it 6 times.</p> <p><a href="http://nsballoonproject.files.wordpress.com/2012/01/img_1496.jpg"><img title="IMG_1496" alt="" src="http://nsballoonproject.files.wordpress.com/2012/01/img_1496.jpg?w=224&amp;h=300&quot; width="224" height="300" /></a></p> <div> <p>CatTrack message</p> </div> <p>This was on a full battery charge. The tracker could be improved by providing height data but this is a minor point. The manufacturer has recently upgraded Cat Track live to version 3 and we would certainly like to test it and hope that its low price is matched by the power of it’s predecessor. Our hope now is that with repeated use, the small lithium batteries hold their charge after deep discharges which are not recommended. Well worth the money for a secondary or primary tracker (if you are willing to risk missing a drop zone within mobile phone coverage).</p> " data-medium-file="" data-large-file="" class="size-medium wp-image-388 aligncenter" src="https://i2.wp.com/eclipse.montana.edu/wp-content/uploads/2015/09/radiosonde2-300x169.jpg" alt="radiosonde2" width="300" height="169" />

USE OF THE DATA: Possible interesting total eclipse experiments include but are not limited to: measuring temperature fluctuations, ozone fluctuations, and gravity wave development. Links to information and pictures about each team’s launch will be included online.

COSTS PER TEAM (for 20 flights): Due to the early phase of the project and the diverse situations for each team, the following numbers are very rough estimates.

  • Radiosonde ground station: $6,000 – $8,000
  • Radiosondes, balloons, helium/hydrogen, basic flight supplies: $5000
  • Travel to launch sites: $2,000

Total: $13,000 – $15,000/team. This estimate is based on eight radiosondes to be used during the eclipse at fifteen minute intervals. Two radiosondes will be extras during the eclipse in case of any technology errors and ten radiosondes will be used to prepare for the eclipse event. This total does not include faculty, staff, or student support, which is highly desirable.
