	Automatic vehicle ground speed control convertible to manual operation - Patent 4727710
		In harvesting a crop with a combine, it is desirable to adjust the ground speed so as to feed the crop to the processor at a rate that permits it to be efficiently threshed and cleaned without excessive loss of grain in discharged material.
		It is a further object of this invention to provide a ground speed control for a combine having automatic and manual modes of operation which includes a manually operable speed control lever which may be shifted in a nonspeed changing direction to establish the automatic mode of operation.
		The ground speed control also includes a control member in the form of a motion transmitting gear segment 32 to which a manually operated control lever 33 is connected.

	DICKEY-john Europe - Radar III Ground Speed Sensor
		The most modern manufacturing technologies and an intelligent construction of the component and especially the antenna allow the sensor to be one of the smallest sensors available on the market.
		Typical applications for the Radar III sensor can be found in the area of the agriculture as for example for the traction control system on tractors, for speed measurement on intelligent planters and drills, sprayers and spreaders.
		But also in other application areas like for construction or forestry equipment it can be necessary to determine the speed regardless of the wheel rotation or the rotation of the shaft.

	Relative Velocity - Aircraft Reference
		Ground speed is also a vector quantity so a comparison with the airspeed must be done according to the rules of vector comparisons.
		Wind speed is the vector difference between the airspeed and the ground speed.
		Comparing this example with the ground reference, we see that the magnitudes of all the velocities are the same, but the sign of the wind speed has changed with the reference velocity direction.

	Relative Velocity - Ground Reference
		We are neglecting cross winds, which occur perpendicular to the flight path but parallel to the ground, and updrafts and downdrafts, which occur perpendicular to the ground.
		Ground speed is also a vector quantity so a comparison of the ground speed to the wind speed must be done according to rules for vector comparisons.
		In the wind tunnel, the ground speed is zero because the model is fixed to the walls of the tunnel.

	Relative Velocity - Ground Reference
		It is important to understand the relationships between the wind speed, the ground speed, and the airspeed.
		Airspeed cannot be directly measured from a ground position, but must be computed from the ground speed and the wind speed.
		The relationship between airspeed, wind speed, and ground speed explains why wind tunnel testing is possible and how kites fly.

	Aerospaceweb.org \| Ask Us - Airspeed and Ground Speed (Site not responding. Last check: 2007-11-06)
		The difference between ground speed and airspeed is caused by the influence of winds on the overall velocity of the aircraft.
		The aircraft is still moving at the same cruise speed of 500 mph with respect to the air, but the difference in the direction of motion of the air means that the wind speed must be subtracted from the plane's airspeed in order to determine the ground speed.
		As indicated in the question, the speed of sound at 35,000 ft is 663 mph (1,067 km/h) according to the standard atmosphere model.

		On the ground or aloft, the wind should be measured on the upwind or lateral side of the volcano in order to be out of any turbulence created by the volcano or topography near the volcano.
		Later, wind speeds were determined from differences in aircraft ground speed (obtained from FAA radar measurements) for flight paths parallel to the plume in both directions (Casadevall and others, 1981).
		Likewise, minimum aircraft ground speeds are recorded when the aircraft is flying directly into the wind and are shown by the solid circles in figure 2.

		A position estimate, based on prior positions and ground speed, is sometimes used to better synchronize the position coordinates with the physical position of the aircraft.
		Ground speed was calibrated by using two reference points established a known distance apart.
		Time and ground speed data recorded during the time interval between flying over the first and second reference point were used to compute the average GPS ground speed and the average ground speed (distance/elapsed time).

		As directed by the High Speed Ground Transportation Act of 1965 and follow-on legislation, the Federal Railroad Administration (FRA) has sponsored the development of High-speed ground transportation (HSGT).
		HSGT is self-guided intercity passenger ground transportation that is time-competitive with air and/or autos on a door-to-door basis for trips in the approximate range of 100 to 500 miles.
		A corridor is a natural grouping of metropolitan areas and markets that, by their proximity and configuration, lend themselves to efficient service by ground transport.

		Ground speed is the speed at which an airplane is moving with respect to the ground.
		(Think of airspeed as the speed at which its propulsion system is set to move it along.) If an airplane is flying with the wind then its ground speed will be enhanced.
		Imagine an aircraft is flying with a heading of 45 degrees and a speed of 100 knots.

		As I broke ground, a particularly nasty gust of wind dropped a wing, and for several seconds, full opposite stick rudder, and elevator were necessary to pick it up.

	MSN Encarta - Magnetic Levitation Train
		Magnetic levitation train technology can be used for urban travel at relatively low speeds (less than 100 km/h, or less than 62 mph).
		Train speeds of 552 km/h (343 mph) have been demonstrated by a full-size maglev vehicle in Japan, while in Germany a maglev train has run at 450 km/h (280 mph) and in China a maglev train has reached a peak speed of 432 km/h (268 mph).
		This new commercial line was expected to relieve passenger demand on the Shinkansen high-speed trains, which currently operate at peak speeds of 300 km/h (186 mph).

		While wing in ground effect technology is not new, there is not a large amount of available data regarding design and performance of these crafts since much of their development has been confined to military applications.
		The theory behind the technology is based on the phenomenum of the observed gain in lift obtained by a craft flying in close proximity to the ground or water surface.
		At cruising speed, these craft trap a cushion of air between the wings and the surface of the water.

	True Heading and Ground Speed
		This routine calculates the heading to be used and the resultant ground speed given true airspeed, desired course, wind speed and direction.
		This is not a problem, as the heading is the same as the course and wind speed is just added or subtracted from the true airspeed in this case.
		(You could also call this the negative drift from the heading?) It will finish with the heading to steer (35.17 degrees) in the Y register and ground speed (156.45 knots) in X. You can verify this is correct by using the polar to rectangular conversions and summation function.
