It is very
much possible for resumption of communications between base station and the
satellite. It also is possible to re-establish communications with the
previous satellites that left our solar system decades ago.
As it was explained before when the transmission reaches its destination the satellite
is not at that place anymore and it has moved miles away from the previous
place. Scientists do calculate the movements of Earth and satellite, the
signal that is sent reaches it, The signal tells the computer on board to
open memory and start recording the data; but by the time the transmission
is over and the signal indicates that I am done and "end of transmission"
the satellite is not there anymore. By referring to the formula, it shows there is
223 meters of
Wave-Shift in every second of transmission to Pioneer 10, which is
located only 12 hours (it is shown as 0.00137 of a light year) from Earth.

If a transmitter or
a relay unit is aboard a plane or the transmission is sent to a relay satellite
that travels at the speed of 500Km/h in the direction of east to west on the
same latitude as Canberra, the wave-shift is minimized by almost two third and
is reduced to 89 meters, which is still receivable by the satellite. (Click
here to see
the formula). The transmissions are sent back by satellite can be received
by the ground facilities as the returned signal is not subjected to a
wave-shift because the satellite is rotating like the Earth does.
Corrections must be made to the way we transmit for a successful
result in transmitting signals.
The
Correction Transmitter can also be put on a train that travels at 150Km/h
from east to west on a straight line. (Click
here to
see the formula). At this speed the wave-shift is reduced to 176 meters
from 223, at this rate we are still able to receive a fainted and distorted
transmission. The transmission is sent from the ground station to the moving
train, plain, or the stationery satellite and retransmitted to the
satellite. The signal after received by the satellite is processed and sent
back and 12 hours later is received by the ground station. The total time
for the transmission would take anything more than 24 hours. This is
important to know that there are other ways to reduce this wave-shift even
further, and it can be used re-establish communications with other satellites
that previously lost communication with.
