The Gps In Fertilizer Apply
(Amitesh)
The GPS in
Fertilizer Apply.
The GPS in Fertilizer Apply has
24 satellites in six orbital planets. The first one had its launch in February
1978, while the last one, in November 6, 2004.Each of the satellites orbits
around the earth twice every day at an altitude of 20,200 kilometers.
These satellites take atomic
clocks and continually broadcast the precise time in accordance with their own
clock, along with administrative information comprising the orbital elements of
their own motion, just as a set of ground-based observatories determine.
Though the receiver is not in need of a precise clock, but it requires a clock
with good short-term stability and the ability to receive signals from
satellites to determine its own latitude, longitude, elevation and the precise
time.
In Fertilizer receiver, a
handheld portable, proves to be highly helpful and useful navigational
equipment for any of the outdoor activity and can be particularly functional
for the Militia member who are taking part in disaster respite and relief or
search and rescue operations. But it should be kept in mind that the system is
reliable to the U.S government for constant operations and the satellite
signals are easy to be shut off or degraded at any time.
GPS (Global positioning
systems) may be very helpful to determine the precise part of the field that a
tractor is crossing. This way, the producers are allowed to map fertility
levels and adjust fertilizer application rates to the particular areas of a
field. The ability which is used to differ the application rates on the go is
known as ?variable rate technology? or other such names: site-specfic
application, prescription farming, of precision farming, to list some.
Signals to a ground-based station, as well as
to the receiver on a tractor, are sent through satellites in GPS or global
positioning systems. And on the other hand, ?correction signal ?are sent to the
tractor by the ground-based station. Thereafter, the tractor?s on-board
receiver stores all of this information together to locate the area of the area
field that the tool is passing over.
