To determine a spacecraft's position in space, NASA generally uses a downlink , or radio signal from the spacecraft to a radio dish in the Deep Space Network of ground receivers.
The supercell - which has been applied effectively worldwide in point-to-multipoint systems - consists of 24 sectors, with each sector supporting a downlink and an uplink.
Ground stations can downlink or uplink information collected on the other side of the globe nearly instantaneously.
The pattern of zeros and ones in the digital readouts ensures that the user segment receivers synchronize only on a NAVSTAR satellite downlink and not on some other electronic signal.
Verizon claims 300-500 Kbps in the downlink , 50 Kbps in the uplink.
The Partners in Flight project has particularly encouraged participation in the downlink from students in groups traditionally under-represented in science and mathematics fields.
The signal is located 97 degrees west longitude with a downlink frequency of 12146.00 MHz.
The IRD is one type of receiver for modulated signals arriving on a satellite downlink .
any TV station can downlink just about any game
Thousands more will view sessions via satellite downlink at 51 sites in 28 states and Canada.
