    MIAMI HIGH ALTITUDE CIRCUMNAVIGATING BALLOON PROJECT plans to launch four High Altitude balloons that should reach an altitude of approximately 10,000 meters (32,800 feet), hopefully circumnavigating our planet Earth.

    They are tentatively scheduled to be launched in November 2019, December 2019, January 2020 and February 2020.

    Each balloon voyage after launch should be trackable. They will be carrying a very light payload powered by Solar Cells, with GPS and sensors capable of transmitting in HF in Hybrid WSPR Mode every two minutes during daylight: its ID, Location, Altitude, Temperature, and Voltage.

    If you are a Teacher, or an Advanced Student at any of our Colleges and Universities Science, Technology, Engineering or Math Programs and are interested in what we are doing we would love to hear from you. Please contact us at

    Their documentation states they will send their telemetry in Hybrid WSPR mode. I'm not familiar with the hybrid form of WSPR. Does it rearrange the decoded material to make it easier to see the voltage, temperature, altitude, and other data in place of the usual SNR, grid, power, etc.? Is this the spreadsheet "decoder" or has there been an application created that's easier to use?

    Does the balloon circle around the earth or does the earth rotate under the balloon?

    Thank you Tom.
    Hopefully, the balloons will join the Jet-stream when reaching altitude. Then they should start their voyage around the planet, if they survive storms and other hazards, one of which is that its payload could stop transmitting...

    Not trying to be a smart Alec, but isn't the altitude of 32,000 feet right where commercial aircraft fly? Would this be a danger to air travel if it "circumvents the planet"?

    Just seems really LOW to me for stuff like this, with range covering "Earth"

    What would be the result if a 737 or A320 "at cruise altitude" encountered one of the balloons? I fly quite a lot for business, and just yesterday they announced my cruising altitude for the flight from Salt Lake to Seattle was at.... 32 thousand feet!

    Just curious - not trying to be critical - just wondering what the safeguards are since this is declared as "circumnavigates the planet" x four such balloons...

    Thank you Dave.
    One OUNCE has 28.5 GRAMS... Our payload weight only about 8.5 Grams. Our balloons are inexpensive like Party Balloons and the gas is pure Helium.
    Hundreds of weather balloons are launched each day with payloads of several pounds.
    I suggest you google Pico Ballons and High Altitude Balloon launches and youtube for more info. and .

    If that is the case just for safety they really need ADS- B reporting transponder, since the payload is over 10,000/18,000 ft and not higher than 60,000, for aircraft safety, FAA law on 1/ 2020 requires aircraft,to be in compliance

    Would you kindly print here the text of FAA Law that you refer to? We would all be interest to read it, as well as all those in the U.S. and all over the world engaged in this Hobby. With regards and 73, Juan /K4LCD
