The paper considers the possibilities of study of the Earth's magnetic field using data not only from the magnetic observatory, but also from repeat stations and sensor networks. The first section describes the equipment of the magnetic observatory. The second section describes the possibility of using various instruments for absolute magnetic measurements at the observatory and at Repeat stations, as well as the specification of the fluxgate sensors developed at the Novosibirsk magnetic observatory. The third section discusses the possibility of building low-cost sensor networks as the basis for cost-effective measurements of the Earth's magnetic field.
