The National Institute of Environmental Health Sciences keeps track of relevant research. [9] Historically, there has been concerns about the effects of aerial applications of pesticides and the chemicals' effects as they spread in the air. For example, the aerial application of mancozeb is likely a source of concern for pregnant women. [10] [11]
A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1]
Airborne Real-time Cueing Hyperspectral Enhanced Reconnaissance, also known by the acronym ARCHER, is an aerial imaging system that produces ground images far more detailed than plain sight or ordinary aerial photography can. [1] It is the most sophisticated unclassified hyperspectral imaging system available, according to U.S. Government ...
The vector from B to C is the wind velocity (W/V), and the third vector is the actual track (TR) and ground speed (GS). The drift angle is marked in red. While dead reckoning can give the best available information on the present position with little math or analysis, it is subject to significant errors of approximation.
Senator Reid in 2002. Initiated by then Senate Majority Leader Harry Reid (D-Nevada) [9] as the Advanced Aerospace Weapon Systems Applications Program (AAWSAP) to study unexplained aerial phenomena (UAP) at the urging of Reid's friend, Nevada billionaire and governmental contractor Robert Bigelow, [10] and with support from the late senators Ted Stevens (R-Alaska) and Daniel Inouye (D-Hawaii ...
Autonomous air combat maneuvering instrumentation (AACMI) are second-generation GPS-based ACMI systems.. Unlike first-generation ACMI systems, which use ground radars to track and record the position of the aircraft on the range, AACMI systems use aircraft-mounted satellite navigation systems such as the US NAVSTAR GPS system.
A Yamaha R-MAX, a UAV that has been used for aerial application in Japan. Japanese farmers have been using Yamaha's R-50 and RMAX unmanned helicopters to dust their crops since 1987. [149] [150] Some farming initiatives in the U.S. use UAVs for crop spraying, as they are often cheaper than a full-sized helicopter.
A U.S. Air Force E-8C Joint STARS, in flight. Airborne ground surveillance (AGS) refers to a class of military airborne radar system (Surveillance aircraft) used for detecting and tracking ground targets, such as vehicles and slow moving helicopters, as opposed to Airborne early warning and control, whose primary role is detecting and tracking aircraft in flight.
