Three US government weather-watching satellites have been scheduled to formally enter the end-of-life stage on June 16th by the National Oceanic and Atmospheric Administration. NOAA has announced that the satellites - 15, 18 and 19 - which are part of the Polar Operational Environmental Satellites, or POES system, will no longer be updated or repaired.
As quoted in the blog USradioguy.com, NOAA said that this means signals will continue to be transmitted but should not be used by anyone for purposes involving safety or other critical matters. Hobbyists will still be able to download weather satellite imagery either via Automatic Picture Transmission on 137 MHz with a V-dipole antenna or via High Resolution Picture Transmission on 1.7 GHz with a tracking dish antenna.
Like the other POES satellites, this trio had provided data that was used in monitoring the environment, forest fires, volcanic eruptions and global vegetation.
