The paper describes a satellite automatic picture transmission (APT) ground receiving station, designed and developed at the Instruments Division, Meteorological, Office, Poona. The station has been in operation at Poona for over six months and has provided good quality Visible and infrared pictures from meteorological satellites ESSA.2, ESSA.8, Nlmbus.3 and ITOS.
The station uses a high gain right circularly polarized helical antenna, a highly sensitive and selective FM receiver and a Mufax facsimile recorder modified suitably to record the satellite cloud pictures. The paper highlights the design details of the antenna and the FM receiver and also described the necessary modifications to the 'Mufax' facsmile recorder for recording correct satellite pictures. Future development plans are also briefly discussed.
