POES satellites include: Defense Meteorological Satellite Program (DMSP), Landsat, SPOT and NOAA Polar-orbiting Operational Environmental Satellites (NPOES). The DMSP and NPOES satellites are operational meteorological satellites. Imagery from successive orbits overlay each other, providing global daily coverage from each satellite. Commercial polar orbiters like Landsat and SPOT, on the other hand, are intended for geophysical remote sensing, with an emphasis on high-resolution and multispectral imagery, at the cost of daily global coverage. POES have meteorological and geophysical importance because of their high-resolution global coverage and well calibrated channels. They are designed to stay in a low earth orbit and reach high latitudes. The POES program began in 1960 with the launch of TIROS-1. Later satellites in the Improved TIROS Operational Satellite (ITOS) program were expanded to capture concurrent multiple-channel data on a daily basis.
