“…The stratospheric balloon model based on transport phenomena (momentum, mass and heat transfer), Gas-Compress-Release system and wind driven balloon dynamic performance used in this work were validated in author's previous studies (Kayhan et al, 2016;Kayhan and Hastaoğlu, 2014).…”

“…When wind drag over the balloon is not manipulated wind drifts the balloon from the floating coordinate. Dynamic forces in the presence of the wind over the balloon were determined author's previous study (Kayhan et al, 2016) and were calculated by using following equations below (Farley, 2005):…”

“…Author's previous study (Kayhan and Hastaoğlu, 2014) implies modeling of stratospheric balloon using transport phenomena and gas compress -release system to place balloon at its orbit without using ballast, to control the vertical movement and extend the flight time. Also, author studied simulation and control of serviceable stratospheric balloon traversing a region via transport phenomena and PID (proportional-integral-derivative) control (Kayhan et al, 2016) to place the balloon at target altitude and ensure balloon's horizontal flights over desired coordinates and interfere with the balloon system whenever technical service is needed. These two studies were proposed for the first time.…”

One of the most difficult problems in stratospheric balloon's design is to keep the balloon's geographic coordinates. Stratospheric wind speeds vary significantly both daily and throughout the year. Wind drag acting on the balloon should be manipulated to control the horizontal coordinates (longitude and latitude degree) of the stratospheric balloons. In this paper, propulsion unit is applied to a wind driven stratospheric balloon to keep balloon's coordinate over flight area. The simulation was applied to a zero-pressure high altitude balloon using actual wind profile for the first time to control the horizontal movement of the balloon. In addition, required thrust power and some parameters effects on it have been investigated. The results indicate that propulsion unit would be helpful to manipulate the horizontal motion of the balloon and to achieve keeping the balloon's geographic location.

“…As an excellent solution for regional positioning, ICPBs have many advantages. Compared with ground-based pseudolites and traditional air-based pseudolites, IPCBs have a wider coverage and can serve more users because their flight altitude can reach tens of kilometers [8,9]. Furthermore, IPCBs have a low energy requirement since they can accomplish its flight primarily relying on buoyancy and wind rather than oil or electricity [10,11].…”

IPCBs (Intelligent Pseudolite Constellations based on high-altitude balloons) are a novel type of air-based pseudolite application with many advantages. Compared with ground-based pseudolites and traditional air-based pseudolites, IPCBs have a wider coverage and a lower energy requirement. Compared with LEO satellite constellations, IPCBs have a stronger signal, a lower cost, and a shorter deployment period. These merits give promising potential to IPCBs. In IPCB applications, one of the key factors is geometry configuration, which is deeply influenced by the balloon’s unique features. The basic idea of this paper is to pursue a strategy to improve IPCB geometry performance by using diverse winds at different altitudes and balloons’ capability of altering flight altitude intelligently. Starting with a brief introduction to IPCBs, this paper defines an indicator to assess IPCB geometry performance, an approach to adjust IPCB geometry configuration and an IPCB geometry configuration planning algorithm. Next, a series of simulations are implemented with an IPCB composed of six pseudolites in winds with/without a quasi-zero wind layer. Some IPCB geometry configurations are analyzed, and their geometry performances are compared. Simulation results show the effectiveness of the proposed algorithm and the influence of the quasi-zero wind layer on IPCB performance.
