IONOSPHERE FIELD STATION

BRIEF HISTORY IONOSPHERE FIELD STATION

  • The Ionosphere Field Station was established in1953 by Prof. Sisir Kumar Mitra at Haringhata, about 50km north-east of Calcutta at a place of relatively low radio frequency interference.
  • Professor Mitra assembled the first manual Ionospheric Sounding System in Asia in 1954 and established it at the Field Station in 1956 thereby putting Calcutta University in an elite global chain of Ionospheric Sounders.

NBS-C2 Ionosonde data for the period 1957-1976 from Ionosphere Field Stationat Haringhata available at the Space Physics Interactive Data Resources (SPIDR) website under the National Geophysical Data Center located at Boulder, Colorado, USA.

In 1966, the Satellite Beacon Group of the Institute of Radio Physics and Electronics was established by Dr. Santimay Basu and tracking of beacons from Low Earth Orbiting satellites, namely, Explorer-22 and -27 startedat 20, 40 and 41 MHz respectively.

During 1972-1973, 136 MHz telemetry transmissions from the near-synchronous satellite INTELSAT-2F2 was used with a rotating Yagi antenna for continuous measurement of TEC and scintillations. This was the first geostationary satellite observation in India.

Signals from the geostationary satellite ATS-6 were recorded at this station at 140MHz in 1975-1976.

The first long-term (1977-1990) measurement from this station with a VHF beacon was performed with the Japanese geostationary satellite ETS-2(130 ° E) by recording the polarization and amplitude of its telemetry signal at 136MHz with an electronically switching polarimeter.

Amplitude recordings from VHF beacon of another satellite, FLEETSATCOM-2 at 244MHz were started in1981.

With the increasing use of space-based navigation and communication systems like the GPS operating in the lower microwave band, it became necessary to observe scintillations with geostationary satellites in this frequency range. Recording of the amplitude of the 1537MHz signal from INMARSAT-2F1 (64 ° E) was started in 1990 with a view to studying scintillations on geostationary satellite signals at lower microwave band.

PROTON PRECESSION MAGNETOMETER (PPM)

  • The PPM has been manufactured by the Indian Institute of Geomagnetism (IIG).
  • It is capable of measuring the total intensity of Earth’s magnetic field over the range of 25000-75000nT with an accuracy of 0.1nT.

COMPUTER ROOM FOR DATA ANALYSIS

  • WiFi facility is available

Late Dr. Santimay Basu and Dr. (Mrs.) Sunanda Basu has kindly endowed a sum of US$30000 to the Institute of Radio Physics and Electronics for various developmental work. A part of the endowment has been utilized for developing the infrastructure of an Auditorium at the Ionosphere Field Station, Haringhata . This auditorium has been named Santimay Basu and Ashish DasGupta Sabhagriha vide resolution taken at the Departmental Committee meeting held on August 24, 2012.
