Television Infrared Observation Satellite allow integration of additional payloads. A change from the TIROS-N through NOAA-D spacecraft was that spare word locations in the low bit rate data system TIROS Information Processor (TIP) was used for special instruments such as the Earth Radiation Budget Satellite (ERBE) and SBUV/2. The search and rescue (SAR) system became independent, utilizing a special frequency for transmission of data to the ground. Television Infrared Observation Satellite TIROS, or Television Infrared Observation Satellite, is a series of early weather satellites launched by the United States, beginning with TIROS-1 in 1960.

Sirius Satellite Radio addition to the audio programming, the Sirius broadcast stream also carries a "Data Services" channel that is utilized by capable receivers and graphical display hardware. Some of the data services offered are traffic speed and flow, marine weather, and fuel prices to name just a few. Examples of capable hardware are the Raymarine SR100 Satellite Weather receiver and the Alpine NVE-N872A Satellite Traffic Ready navigation system. The Sirius signal is separated into three carriers, one each for the two satellites, and the third for the terrestrial repeater network where available. Sirius receivers decode all three 4 MHz carrier signals at
