NOAA's new G-IV SP, N49RF, has a
certified ceiling of 45000 feet, a range of 4075 nm, and a
cruising true air speed of 440 knots. The aircraft is instrumented
to measure 1-Hz flight-level data, including GPS position, radar
altitude, pressure, all three wind components, temperature, and
humidity. The primary instrument systems are the GPS dropwindsonde
system, a main aircraft data system and local area network capable
of handling specialized sensors, and a workstation (HAPS) for processing and
coding the data from the GPS sondes for direct transmission to NHC
and NMC via a 9600 baud (2400 bd initially) satellite communications
link.
