The GOES-16 Advanced Baseline Imager before satellite integration. On 23 May 2018, NOAA announced that there were problems with the cooling system of the Advanced Baseline Imager. [9] [10] Due to the cooling failure, infrared and near-infrared imaging was only possible 12 hours per day. The issue affects 13 of the infrared and near-infrared ...
A satellite whose orbital period is an integer fraction of a day (e.g., 24 hours, 12 hours, 8 hours, etc.) will follow roughly the same ground track every day. This ground track is shifted east or west depending on the longitude of the ascending node , which can vary over time due to perturbations of the orbit.
The Geostationary Operational Environmental Satellite (GOES) program began as a joint effort between the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) in 1975 to develop geostationary weather satellites following the success of the Applications Technology Satellite (ATS) and Synchronous Meteorological Satellite programs ...
The Earth-observing ERS-2 satellite first launched on April 21, 1995, and it was the most sophisticated satellite of its kind at the time to be developed and launched by Europe.
A GPS disciplined oscillator unit with a GPS antenna input, 10 MHz and 1 pulse-per-second (PPS) outputs, and an RS-232 interface.. A GPS clock, or GPS disciplined oscillator (GPSDO), is a combination of a GPS receiver and a high-quality, stable oscillator such as a quartz or rubidium oscillator whose output is controlled to agree with the signals broadcast by GPS or other GNSS satellites.

While the number of satellites launched into orbit is relatively low in comparison to the amount of space available in orbit around the Earth, risky near-misses and occasional collisions happen. The 2009 satellite collision entirely obliterated both spacecraft and resulted in the creation of an estimated 1,000 new pieces of space debris larger ...
