«Because of the broadcast from the space station, AAUSAT5 is at a much lower
altitude than the satellites we've previously sent up.
Not exact matches
A constellation of more
than two dozen GPS
satellites broadcasts precise timing signals by radio to electronic GPS receivers which allow them to accurately determine their location (longitude, latitude, and
altitude) in real time.
(Suborbital means the vehicle can fly only to a lower
altitude than is necessary to start orbiting the Earth — it would have to travel higher, and faster, to reach
altitudes achieved by orbiting
satellites or the International Space Station, for example.)
As a result, scientists typically ignore
satellite data for
altitudes lower
than 15 kilometers, Ridley says.
It doesn't get much better
than this 2018 Jeep Grand Cherokee
Altitude, which boasts a push button start, a navigation system, stability control, traction control, and Sirius
satellite radio.
And, as the
satellite observations of Spencer and Braswell showed, as the planet warms over a period of several months, clouds act as a net negative feedback (the reflecting low -
altitude clouds increase more
than the absorbing high -
altitude clouds with warming).
It is measured by two independent methods (balloons and
satellites) and they both show the warming at
altitude is similar (indeed, slightly less)
than at the surface.
Anderson and his colleagues start with a new and unexpected observation, based on high -
altitude flights and
satellite measurements: powerful updrafts from powerful summer thunderstorms can send moisture much higher into the stratosphere
than anyone had thought.
