Is it legal?

Yes it is, we are flying under FAA 101 exemption rules.

Our Mission and Goal
To launch a high altitude balloon for long duration and multiple trips around the world. For this flight we will use a balloon called the SBS-13 (expensive) that has the capability of flying in the altitude range of 43000-45000 ft.. It will
be filled with hydrogen to obtain higher altitude. We hope to fly around 45,000 ft. It will be solar powered only (no batteries so it will only transmit during daylight). We will receive tracking every 10 minutes via  WSPR on HF.
Tracking data will give us Altitude, Speed, Voltage, Temperature, future course predictions. Entire payload is approx 9 Grams. Transmissions will be turned off over the UK, Yemen, and North Korea due to regulations.

About the Tracking
We are solar only so no data or reports
during the dark hours. Due to regulations no transmissionsover North Korea, Yemen, or UK.

HabHub
This site gives you speed, heading voltage, Altitude, Temp, lat and Lon. Under settings you can set things like metric or imperical measurements. If you click on Hysplit, it will give you estimated prediction paths for the balloon.
WSPR
Our WSPR transmitter works on HF at 14 Mhz and has a range of over 5000 miles. It is only running 10 mw of power. Baud rate for data is 1.4 Baud. Yes you read it right 1.4. The signal bandwidth is only 6 Hz wide. Standard WSPR does not give us all the data we need. We are using a modified WSPR protocol which uses an additional time slot to send gps data information.

The payload consists of a  home made tracker (yo3ict design) that contains the GPS system, and an HF transmitter running only about 10 milliwatts.This is less power than most of your blueTooth devices at home.We are trying a different power system on this launch. Ths solar panel is a single 3.6 volt 100 ma panel. We are using s 2 F super capacitor across it and have implemented a 3.3 v regulator to get the proper voltage to the tracker board. See Pictures at the right of this page.

Day 13 Sat May 23, 2020  Great flying today  Communications and tracking was perfect. connected every 10 minutes solid. First half of the day we were moving little over 100 mph but it slowed down to 50-60 mph as it approached the mainland U.S.   We are about 400 miles off shore when we lost sun light tonight. The balloon should appear over San Francisco in the morning around 8:15 AM pacific time. (1500 utc)

 

Day 11, 12  Thurs and Friday May 21-22, 2020  We crossed China , the yellow sea, and Japan. Speeds up to about 115 mph.  Communications problems have gone away. We are getting solid updates every 10 minutes.  Altitude still good at 43,000 ft.   Comm problems over the middle east were probably propagation and the fact that not many use wspr in that area of the world.

Day 9, 10  Tues and Wed May 19-20  We ar finally moving again  Crossing Saudi Arabia, Iraq, Iran, and Afghanistan.  Communications problems are hurting us.  only a few reports per day. Altitude goos at 43,000 ft.  and we are picking up speed to about 50-70 mph.

Day 8 Monday May 18th, 2020 Still stuck in Egypt and not moving.  Cant get a break to get out of here.  Also communications starting to get spotty.  Are we developing issues with our tracker transmitter on 20 meters?

Day 7 Sunday May 17, 2020 Still stuck in slow speed in Egypt. Looks like we have turned east and might break out of the slow speed in the next 12 hours. Altitues is good at 43,241 ft.  It woke up today at 0510 UTC and went back to sleep at about 1510 UTC.  We should wake back up about 9:00 PM Central time and the balloon should be over Israel.  We hope at that point we start picking up speed again.

Day 5-6  May 15, 16, 2020 We seem to be stuck in a weather pattern  the past 3 days where we are pretty much sitting still.  Speeds are around 8 mph and we are slowly heading south in Egypt.  altitude still great at 43,000 ft. 

Day 4 May 14, 2020  Woke up exactly on the time we predicted today.  Awake at 0540 UTC over Italy.  Balloon has slowed down some as we only covered about 350 miles during the night. Altitude has increased to 43,635 which is very good. Speed is about 25-30 mph.  sunlight ended around 1520 UTC today and the tracker went to sleep.  We expect it to show up over Turkey when it wakes up.  Estimating the wakeup time to be around 11:50 PM central time tonight (0750 UTC Sat) All systems working great.

Day 3   May 13, 2020  It woke up today at 0750 UTC just off the coast of Morocco.  Flying at a steady 42,000 ft and reached the north border of Morocco by time to go to sleep again.  Speed averaged about 90 mph.  Went to sleep at 1710 UTC.  its course is not heading to Italy.  We should pick it up over italy in the morning once sunlight appears there.

Day 2   May 12, 2020  Things went well today as we crossed the Atlantic. No issues. We flew a steady 42,000 ft and were averaging 100 mph. It went to sleep at 1950 UTC as we lost the sun.

 

Day 1 Launch  May 11, 2020  Everything looked good. Great launch.  Wind was only about 1-2 mph. We are using less free lift on this flight. Only 6.5 grams of hydrogen. Reached our float altitude of 42,500 ft in 3.5 hours.  The tracker reported its position every 10 minutes for about 9 hours and 30 minutes until we lost the sun on the east coast.

Shown is the finished tracker we are flying for W5KUB-18.   The tracker and voltage regulator are glued and taped under the back side of the solar panel.  The gps antenna sticks up off the edge of the panel. A 20 meter dipole completes the entire system. The antenna is 34 ft total.  One half (17 ft) goes from the tracker up to the balloon, and the other half (17 ft) hangs below the tracker.

This is a relaunch from a previous failed mission

UPDATE: We had a great launch on April 6, 2020. flew at 30,000 ft and speeds up to 100 mph.  We are having some trouble with the transmissions. The balloon is not reporting every 10 minutes like designed.  There are periods of 2 - 4hous where it does not transmit.  It is still flying and not down. We should get reports from time to time. Keep checking. 

UPDATE  APRIL 10, 2020.  The balloon reported this morning with altitude of 1500 ft. It was going down. There were a lot of storms in Spain over night. We may have also had a balloon failure. It went down In the mountains near Luque, Spain.

Day 4   March 10, 2020   Still no transmissions from balloon today. We are guessing it is down somewhere around the UK.  Each day of no reports gets us closer to verifying that it is down. Sun angles are very low up there. It is possible that it moved very north and into the dark.  There have been some balloons that stopped transmitting and then started again 90 days later.  We just need to keep an eye out for this one. Possible it might show up later but doubtful. We are already working on a new launch to go around the world. 

Day 3 March 9, 2020   nothing heard today.  It could still be up. The solar cells do not function when the sun angle is about 30 degrees or less.  We estimated it near London today but the highest sun angle at London was only 34 degrees. Also the predicted path took us way north of the UK meaning that the sun was even lower up there.  Probably max height was below 30 degrees.  We did go through some storms in the Atlantic last night but that was during a period of no transmissions.  We will have to wait until tomorrow to see if the balloon comes back alive. Others that have sent balloons up have gone into that region and it is dark up there and their balloons did not report for weeks. 

Day 2  March 8, 2020    the tracker came back alive around 8:00 am local time near Bermuda this morning when it started receiving the sun.  We are following the NOAA prediction path very closely.  Present speed at 11:00 AM central time was 154.8 mph.  The altitude is at 32,808 ft. 

Day 1 Launched at 12:10 AM March 7, 2020 Launch went great. Balloon went straight up. Vertical rate of climb was around 165-200 feet per minute. Low level winds was only moving the balloon about 25-30 mph as it increased altitude. Once we hit 27,000 we got in to an air stream running around 55 mph and it should turn into 80-90 mph in the next couple hours.  Used hydrogen and no safety issues. We still have all our eye brows and our fingers. The solar panels do not function when the sun gets below 32 degrees therefore we will lose it around 3:30 pm each day. We now have to wait until tomorrow track to see how it is doing.  We are solar panel power only so no tracking during the night. It is running uner 3 calls.  On WSPR you can track it using W5KUB. On APRS you can track using W5KUB-12, and on HabHub you can track it as KUB1

Update: March 14, 2020 the aprs on the balloon started sending today. It appears to be on the ground on the beach of the Baltic sea in Poland. Hams are trying to get to it but the coronavirus has stopped people from traveling there to look for it.

LOST   Looks like we went down somewhere around the Russian boarder. Once it became night and we crossed the board we never heard it again

Day3 March 1, 2020 We have made it all the way to Germany. Average speed across ocean was about 115 mph.   Over Europe we were only traveling about 55-65 mph. Once we passed over Stuttgart, Germany we picked up speed to 99 mph. Must have hit the autobahn.  Finally went dark, so no more tracking for about 12 hours.  We should be in Poland by 3:00 PM central time.  Everything working perfect. And because we have a heavy payload (25 grams) we are stuck at about 28,500 ft.   This means we could hit the top of some storms.

Day 2 Feb 29, 2020  as predicted wspr is showing it mid way over the Alantic. we only have wspr so no altitude, lat, long, etc. Not much going on as the balloon is in the dark most of our daylight.

Launch date: Feb 28, 2020 at 0915 Central.  Filled a test balloon to launch for wind direction. No one injured, still have all fingers and eye brows. Payload was a little heavy (25 grams) . We used 2 Chinese Qualtex balloons ($2.00 each). A little cloudy but cleared up to be a totally sunny day about 15 minutes after launch. Each balloon carried 3 grams of free lift.  It took about 11 minutes to reach 2700 ft. Climb rate at 9000 ft was about 170 ft per minute.   Average speed 117 mph. By 4 PM eastern it had made it almost to the Atlantic coast of North Carolina .At that point we went into darkness and no transmissions until next day.No tracking during dark hours due to solar power only.

Day 29, Feb 25, 2020  Still no word from the balloon.  We think we hit a major storm off the coast of Africa. It has gone dark. There have been other similar balloons that went silent for over 94 days and then came back alive and started reporting. Its a small chance this will happen but we will keep checking each week on this balloon's status. In the mean time we are planning a new launch of a small balloon around mid March.

Day 6 Feb 1, 2020 We have not heard from the balloon in 3 days. Last report it was entering Africa.  Probably has gone down but we are not certain. We will keep watching over the next week to see if it reappears.  It was flying great and have no indication it was losing altitude. It was flying steady at 41,000 ft. We went into darkness so no reports during the time frame in question.  We are already working to build our next tracker based on YO3ICT. tracker weighs only 1.5 grams. Should be built by end of Feb and we will schedule another launch soon.  In the meantime lets keep watching for this one to re-appear.

Day 2 Jan 27th, 2020  as predicted wspr is showing it mid way over the alantic. we only have wspr so no altitude, lat, long, etc. Not much going on as the balloon is in the dark most of our daylight.

Launch date: Jan 27, 2020 at 0945 Central.  Filled a test balloon to launch for wind direction. It exploded on us. No one injured, still have all fingers and eye brows. Payload was a little heavy (27 grams) and we added 8 grams of Hydrogen as free lift. Today was about the last option to launch. WX prediction was to be partly cloudy. We had some clouds on launch but within about 45 minutes the skies were clear. Wind was averaging about 3-4 mph. Upon launch the balloon went almost straight up. It was already reporting position by 6000 ft.  Cloud ceiling was low. Average speed 100 mph. By 4 PM eastern it had made it 100 miles from east coast and we lost sunlight so no tracking. solar panel is flat and horizontal. Sunset was at 6 pm but it was straight off the side of the panel so no voltage. It should show up on wspr sometime in the morning over the ocean during daylight.
