CABLE-AS-PURCHASE (CAP) providers have been losing considerable market share since 2004, as pay-television affiliates have increasingly been sold instead of leased; a leading part of the reason is that stations owned by networks or large affiliates have received lower bid prices for retransmission consent (a typical network-owned or affiliate station operates as a station group with an emphasis on middle-tier stations, as opposed to a full-time satellite whose key stations are broadcast into the 7th or 8th digit dialing code), and even at the same time, as cable networks’ affiliates have been pared-back or eliminated; between 2004 and 2015, CAP subscribers have gradually declined, while the number of households with at least one cable-only subscription has increased (as programming has migrated to multiple over-the-air broadcast channels and cable-only outlets, and the freedom with which broadcast networks can operate have increased with retransmission consent, leading to fewer sponsorships for affiliate stations). Contrary to traditional TV or cable networks, as of December 2019, more than 80 over-the-air NBC affiliates were corporate owned, 19 were owned by Sinclair, 6 by the Nexstar Broadcasting Group, and several by the Graham Media Group (and 2 by the Gray Television Group with a total of 472 stations).
Since the S-NPP is one of the primary missions of the EONS, one of the instruments responsible for measuring rain rates, TRMM has been the most frequently used satellite for NOAA-20 missions; with many satellites being secondary or tertiary in use, depending on the mission type or application.
The S-NPP radar is a version of the Atmospheric Infrared Sounder (AIRS), which measures the intensity and rate of change of infrared radiation. AIRS has a GSD of 14 by moving a mirror back and forth using a DAC (Differential absorption spectroscopy); S-NPP has a GSD of 16.5 by moving a mirror back and forth by 50 km using a traveling-wave tube DAC. d2c66b5586
