Definition

  • [Source: "Global Hawk In-flight turbulence Sensor", Ru-Shan Gao, Laurel Watts, Steven Ciciora, and David Fahey, NOAA Earth System Research Laboratory, Boulder, CO, 2010, ftp://ghrc.nsstc.nasa.gov/pub/doc/grip/gripghis/GHIS_Description.pdf.] The NOAA Global Hawk In-flight turbulence Sensor (GHIS) is an autonomous instrument that can be placed at various GH instrument locations to detect 2-axis local accelerations (the instrument is normally placed such that one axis is horizontal and the other one is vertical; both are perpendicular to the line of flight) caused by turbulence and local vibrations. The GHIS instrument may also be reprogrammed to test command, control, and communication (C3) links. The instrument will broadcast the User (10 Hz) and Status (1 Hz) UDP packets with parameters of local acceleration as well as the local air temperature and pressure at the instrument location and the voltage of the aircraft DC power. The entire dataset is also stored on the instrument as CSV text files. The GHIS specifications are given in Table 1.
