Abstract: Wind information in much greater detail than that provided by conventional Rawinsonde equipment has long been desired by designers of missiles and space vehicles. A development project has been taken up to develop indigenous Jimsphere which is a constant volume, super-pressure, self-reflecting aerodynamically stable spherical balloon. In its first phase, development of Constant Volume Balloon (CVB), which is a super-pressure self-reflecting balloon, is developed and flight tested. In this paper a brief description of development of CVB and comparison of its wind profile with that of the Rawin are made. It is confirmed from the radar data that the CVB is providing signals that are more stable than those from the Rawin, resulting less noise in the data. From the comparison of wind profiles obtained from CVB and Rawin, it is found that CVB is more responsive to small scale wind variations than the Rawin because of its inherent advantages like less mass, constant volume, omission of reflector and avoidance of induced pendulum oscillations. The CVB has a steadier rate of ascent than the Rawin.
