Digital Satellite System is the initialism expansion of the DSS digital satellite television transmission system used by DirecTV. Only when digital transmission was introduced did direct broadcast satellite (DBS) television become popular in North America , which has led to both DBS and DSS being used interchangeably to refer to all three ...
The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth. After the despreading or removal of the direct-sequence modulation in the receiver, the information bandwidth is restored, while the unintentional and intentional interference is substantially reduced.

Newer Digital Spread Spectrum (DSS) variants spread their signal over a range of frequencies, providing more resistance to signal fade. This technology enabled the digital information to spread in pieces among several frequencies between the receiver and the base, thereby making it almost impossible to eavesdrop on the cordless conversation.
The new box, called XUMO, replaces the old set-top cable box and has several new features.
DSS-46 was decommissioned in late 2009. In May 2010 the American Institute of Aeronautics and Astronautics declared the antenna a Historical Aerospace Site, and the antenna remains in place. [9] DSS-49: Active: 64m: Radio telescope at Parkes Observatory, capable of linking in to provide support, though it is a receiver only and is incapable of ...
Construction of the first radio telescope, DSS 11 or the Pioneer Deep Space Station, was begun by the United States Army and taken over by NASA after its creation. It is a 26-metre (85 ft) parabolic Cassegrain antenna capable of receiving signals in the 1 to 3 GHz range. [ 9 ]
It generates a stream of real-time decryption keys which are broadcast over the Internet to remotely located satellite receivers. Limiting factors in the number of remotely located satellite receivers are the network latency and the period between the updated keys and the ability of the card client's receiver to use the decrypted key stream.

A software GNSS receiver is a Global Navigation Satellite System (GNSS) receiver that has been designed and implemented using software-defined radio.. A GNSS receiver, in general, is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position, velocity and time (of the receiver).
