Raven Aerostar Tethered Aerostats in xyHt Magazine
xyHt Magazine's October 2014 issue explores why high-tech helium balloons may be a better choice than UAVs. Craig Laws, senior product manager of aerostats and military decoys, explains how Raven Aerostar's tethered aerostats provide unmatched performance and complete situational awareness for a multitude of needs.
GEOSPATIAL PROFESSIONALS are able to choose from an increasingly wide array of platforms on which to deploy ever more accurate and smaller sensors. Lately, unmanned aerial vehicles (UAVs) have been getting most of the buzz (pun intended). However, in many situations, high-tech versions of one of the earliest flying devices, tethered aerostats, are a better option. Like UAVs, they are much cheaper per flight hour to operate than manned aircraft; however, they can carry a much larger payload than small UAVs, can stay up for a much
longer time, and are legal to use in the U.S.
I discussed tethered aerostats with Craig Laws, senior product manager of aerostats and military decoys at Raven Aerostar. The company manufactures aerostats ranging in size from 250 cubic feet (about twice the size of a car) to 120,000 cubic feet (about the size of a high school gymnasium) with a payload capacity ranging from 5 pounds up to 1,500 pounds. They can generally operate with wind speeds of up to 50 knots. “It really doesn’t matter that much what the payload is. It is all about size, weight, and power” or SWAP.
