Infrasound and Gravity Waves Over the Andes Observed by a Pressure Sensor on Board a Stratospheric Balloon

Journal of Geophysical Research D: Atmospheres, 2020
The study of infrasound (acoustic) and gravity waves sources and propagation in the atmosphere of a planet gives us precious insight on atmosphere dynamics, climate, and even internal structure.

Flight performance simulation and station-keeping endurance analysis for stratospheric super-pressure balloon in real wind field

Aerospace Science and Technology, 2019
For the absence of the propeller system to resist wind load, the balloon will float everywhere with unstable position. In order to fix the balloon within a specific district and extend the station-keeping endurance, an effective approach that utilizes ...

Reinventing Stratospheric Ballooning

AIAA Balloon Systems Conference, 2007
The modern stratospheric balloon was invented in the late 1940’s in Minneapolis Minnesota. Collaborative efforts between General Mills and the University of Minnesota, sponsored by the Office of Naval Research, advanced the state of the art rapidly in the 1950’s.

A stratospheric shuttle balloon

12th Lighter-Than-Air Systems Technology Conference, 1997
This paper introduces theoretical analysis of a balloon shuttling between the stratosphere and the ground surface. As an analytical model, an axisymmetrically elliptic balloon is adopted which consists of an outer envelope and two inner gas bags. Two inner bags respectively hold helium; one for lifting its payload and the outer envelope weight, and ...

Stratospheric Balloon Attitude and Position Determination System Based on the VHF Omnidirectional Range Signal Processing: TARDIS experiment

IEEE International Workshop on Metrology for AeroSpace, 2019
The aim of the experiment "Tracking and Attitude Radio-based Determination In Stratosphere" (TARDIS) is to develop an alternative navigation system based on digital processing of the VHF Omnidirectional Range (VOR) radio-navigation system signal.

Superpressure Balloon Flights in the Tropical Stratosphere

Science, 1969
Seven balloons were launched successfully from Ascension Island in January 1969. The balloons, flown at altitudes of 20 and 24 kilometers, will make possible a detailed analysis of the stratospheric circulation near the equator and will hopefully lead to an understanding of the quasi-biennial stratospheric oscillation in the tropics.

Global stratospheric balloon constellations

Advances in Space Research, 2002
A revolutionary concept is discussed for a global constellation and network of hundreds of stratospheric superpressure balloons that can address major scientific questions relating to Earth science. Global Aerospace Corporation is proposing this role for a new generation of stratospheric platform based on advanced balloon technology, called the ...
