Abstract: A control system for an atmospheric balloon system includes a navigation parameter system having a meteorological characteristic input, a balloon kinematic monitor, an objective input and a parameter range generator configured to generate an altitude search range for the atmospheric balloon system based on air stream vectors, balloon kinematics, and a target balloon position. An onboard balloon control system is in communication with the navigation parameter system and includes a comparator to determine a course difference of a measured course relative to a course range. An altitude selection module selects a target altitude within the altitude search range having an air stream vector that decreases the course difference. A propulsion selection module is configured to select a propulsion value that decreases the course difference.

Abstract: Methods and apparatuses for providing wide-area surveillance with a radar and/or other sensors from a stratospheric balloon launched from a land or ship platform for detection, tracking, and classification of maritime, land, and air objects such as ships, people/vehicles, or aircraft are described generally herein. In one or more embodiments, an apparatus is battery operated and includes a stratospheric balloon filled that is filled with helium when it is launched and a gondola with a radar system and communication equipment suspended therefrom. When launched, the apparatus can travel with the wind until it reaches an altitude of approximately 68,500 ft., then it can move substantially horizontally with the stratospheric winds until it returns to earth via a parachute. Multiple apparatus launches at periodic intervals can help provide continuous coverage of the surveillance area. The apparatus can be recovered and re-used or can be considered expendable.

A controller can be coupled to one or more of the power source, the power source actuator, the first and second thrust generators and the sensor. The controller can maintain a pitch of the hull by translating the power source within the pod in association with the pitch signal.

The information of each potential respondent includes an identifier of a mobile device associated with the potential respondent. The method further includes a step of sending invitations to participate in the survey to a group of target respondents selected from the potential respondents based on retrieved application data from the mobile devices associated with the potential respondents. A system, including data storage and a processor, is also presented. The data storage stores information of potential respondents, including an identifier of a mobile device associated with the potential respondent. The processor retrieves data from the mobile devices and sends invitations to participate in the survey to mobile devices associated with a group of target respondents selected from the potential respondents.
