Research: UAS Mission ASCI 530 - Unmanned Aerospace Systems John Van Geem To pursue responsible Arctic region stewardship and strengthen international cooperation, the National Oceanic and Atmospheric Administration (NOAA) is looking at a number of UAS for atmospheric observations. To accomplish this mission, the NOAA is looking at specifications for the IAI HERON, AEOVEL FlexRotor, and AAI Aerosonde UAS, (Coffey, 2014). It is NOAA’s vision that UAS will bring a comparable impact to observing strategies, as satellites have done in the past. Some of the mission profits that these UAS can contribute to is ice ridge monitoring, marine mammal monitoring, search and recovery scenarios, oil spill monitoring, and tracking marine debris from ships, (Coffey, 2014). The IAI Heron is capable of SATCOM communications for extended ranges, helping out for mission over deep ice where no previous transportation is possible. Proved to be operable in extreme cold, snow, and icy s...

UAS in the National Airspace System ASCI 530  John Van Geem April 14, 2017 The Traffic Collision Avoidance System (TCAS) is a common collision avoidance detection system used by aircraft within the National Airspace System (NAS). TCAS can give an early alert or warning if two aerospace platforms are on imminent trajectory for mid-air crash or collision. In order for a airframe to use TCAS, it has to be fitted with a transponder that emits a specific frequency for detection amongst other TCAS systems. However, TCAS is only a requirement on aircraft with a weight of over 12,600 lbs or above (FAA, 2009). According to the Department of Defense UAS Groups, which designates they type of UAS according to size and operating altitude capabilities, only groups 4 and 5 could even be close to TCAS standards, though Group 3 is able to reach altitudes just under flight level 180.  Examples of the types of UAS in group 3 are the RQ-7B Shadow, RQ-21 Blackjack, and ...
