Remote sensing satellites orbit Earth and other planets to study them from space using electronic cameras and instruments. They provide important applications in agriculture, soil analysis, forest monitoring, disaster management, and tracking water and land resources. India has launched 23 remote sensing satellites since starting their program, with most still in service today providing remote imaging data.
