The raw magnetic data obtained by regular observations at magnetic observatories are the basis for research in many fields of science. The reliability, regularity and efficiency of the data ensure the quality and effectiveness of researches, including in the field of the space weather forecasts. Hardware developers with technical and technological advances provide observatories with the wide range of digital magnetometers, the modern information and communication systems of the data storage and database formation provide the scientific community with access to the results of the measurements. Processing of raw data on the primary analysis step has a significant importance. The report shows that much of this work can not be delegated to the outer data centers, and must be carried out directly at the observatories. First of all, this is due to the need to consider local environmental factors that affect the results of the measurements, as well as monitor the state of the equipment and make timely operational decisions for possible faults, failures, etc. In spite of the intensive development of information and communication systems and technologies, there are substantial gaps in methodological (to a lesser extent) and software (largely) support of the magnetologist workplace, which are being addressed in this work. The authors developed specialized software system, including all stages of the processing of the magnetic data, since their primary analysis to high-tech mathematical methods for the study of processes in the magnetosphere-ionosphere system. Much attention is paid to the creation of effective, reliable and user-friendly software for magnetologist, including procedures - on identification and removal of noise, control the baseline values, filling gaps in the data, as well as the preparation of the final data with the status of Adjusted, Quasi-definitive and Definitive, required by the INTERMAGNET standards. A significant part of the programs implemented and effectively used at "Paratunka", "Khabarovsk", "Magadan" and "Cape Schmidt" magnetic observatories of IKIR FEB RAS (Russia), testing the individual modules is performed at "Hyderabad" and "Choutuppal" observatories of CSIR-NGRI (India). This work was supported by Indo-Russia collaborative project of RFBR No 16-55-45007.
