Orbital evolution of high-altitude balloon satellites
We investigate the motion of artificial satellites with large area-to-mass ratios in high-altitude low inclined orbits, perturbed simultaneously by solar radiation pressure andEarth’s oblateness. Our study is based on recent theoretical advances in circumplanetary dust dynamics (Hamilton & Krivov 1996). Applying these methods to the motion of balloon satellites, we write down and analyze the or...
متن کاملImplementation of Solar Tracking Onboard a High-Altitude Balloon Platform
The HELIOS program is a series of four solar tracking missions with the goal to demonstrate the feasibility of solar tracking on a high altitude balloon platform while maintaining a low mission cost. For this purpose, a tracking system was developed that could be accurate, simple, and cost efficient. This paper documents the tracking system utilized by HELIOS III and IV both physically and algo...
متن کاملA Telemetry Beacon and Digital Camera Controller System for Experimental High Altitude Balloon Flights
A simple and inexpensive flight payload system for experimental high altitude balloon flights is described. The payload includes a simple 2m FM/CW telemetry beacon transmitter, an automated ID'er/controller which can provide up to 16 different CW telemetry status messages and also control an inexpensive digital camera for collecting still images at predetermined intervals during the balloon fli...
متن کاملSum-Rate Analysis for High Altitude Platform (HAP) Drones with Tethered Balloon Relay
High altitude platform (HAP) drones can provide broadband wireless connectivity to ground users in rural areas by establishing line-of-sight (LoS) links and exploiting effective beamforming techniques. However, at high altitudes, acquiring the channel state information (CSI) for HAPs, which is a key component to perform beamforming, is challenging. In this paper, by exploiting an interference a...
متن کاملCerebral Venous Sinus Thrombosis Masquerading as High Altitude Cerebral Edema at Extreme Altitude
Introduction: Extreme altitude travel has gained popularity globally for adventurous, scientific, and military endeavors. Cerebral venous sinus thrombosis (CVST) at extreme altitude is a rare, covert, and emergent condition requiring immediate intervention. Case Presentation: A case of CVST masqueraded as high altitude cerebral edema (HACE) at 6700 m/22000 ft i...
