Advanced Support Systems

CSBF Flight Systems
  • Longer flights require systems with higher reliability
  • Unique systems for these longer flights are also required
  • The long duration Super Pressure flight systems are similar to those provided for the NASA LDB missions
  • CSBF has developed new systems as well as new unique systems for the long duration Super Pressure Balloon flights
    • Reliable solar power and charging systems for long flights
    • Flight control and data storage including redundant flight computers for telemetry, ballast, and terminate
    • Communication systems for line of sight as well as long duration flight
    • Other flight systems to support unique needs for Super Pressure Balloon flights including differential pressure measurement, environment measurements, tendon loads and more
    • Camera systems smaller, lighter weight, fixed focal length, pan/tilt/zoom systems, and systems to obtain images from over the horizon on very long flights
  • Balloon, launch & recovery services, payload development support

Flight Trajectory Control
  • The potential for flight trajectory control will be an enabling technology for long Super Pressure Balloon flights
  • Typically a balloon floats along with the prevailing winds for the length of its flight
  • The goal of trajectory control is to slightly modify the balloon flight track over time to be able to steer the system to preferred flight latitudes
  • This would allow a balloon to be launch from one location and then to be shifted to a latitude band where there will be little population or land to overfly during the mission. Toward the end of the mission, the balloon would be steered back to a desire location to safely terminate the flight and recover the science instrument.
  • Flight Trajectory Control is a long term advanced support system desired by the NASA Balloon Program Office
