A Deep Space Optical Communication demonstration is included with NASA's Psyche mission, launched on October 13, 2023. The Psyche spacecraft will explore the metal asteroid 16 Psyche, reaching the asteroid belt in 2029. [10] [11] [12] DSOC first light was achieved on November 14, 2023. The experiment successfully transmitted a 15-second ultra ...
The U.S. Navy's Communications Satellite Program Office (PMW 146) of the Program Executive Office (PEO) for Space Systems in San Diego, is lead developer for the MUOS program. [4] Lockheed Martin Space is the prime system contractor and satellite designer for MUOS under U.S. Navy Contract N00039-04-C-2009, which was announced on 24 September 2004.
However, the design concept surpassed the technological capabilities of the time, leading to the cancellation of the program in May 1962. The Initial Defense Communications Satellite Program (IDCSP) was proposed as one of two recommended follow-up approaches to deliver a working satellite. Philco (now Ford Aerospace) was contracted for the work.
Satellite communications are affected by moisture and various forms of precipitation (such as rain or snow) in the signal path between end users or ground stations and the satellite being utilized. This interference with the signal is known as rain fade. The effects are less pronounced on the lower frequency 'L' and 'C' bands but can become ...
It routinely downloads high-volume data from the Sentinel 1A/B and Sentinel 2A/B spacecraft to ground. So far (April 2019) more than 20000 links (11 PBit) have been performed. [23] As of May 2023, EDRS has over one million minutes of communications [24] with more than 50,000 successful inter-satellite links. [25] [26]
