LAUNCHERS

AVAPS launchers are either manually operated or fully automated. In manual launchers, an operator initializes and loads the dropsondes into the launch tube. The release valve may also be operated manually or through an electronically controlled valve. Fully automated launchers are much more complex and designed for remote controlled operation. In these launchers, the dropsondes are transported from a storage bin into the launch tube, initialized, and then launched by a fully robotic system. The operator controlling the system may be onboard the aircraft or may be located at the mission control center on the ground. Manual systems are still used by the bulk of AVAPS community, but there is growing interest in automated systems.Currently, there are only 2 fully automated AVAPS Launchers.  One is implemented on the NSF/NCAR G-V and the other is on the NASA Global Hawk.
