Early Soviet satellite magnetic field measurements over 1964 and 1970

Abstract. We present the collection of magnetic field absolute measurements performed by early Soviet magnetic satellite missions Kosmos-49 (1964) and Kosmos-321 (1970). Totally 17300 measured values are available for Kosmos-49 mission, covering homogeneously 75 % of the Earth's surface between 49° north and south latitude. About 5000 measured values are available for Kosmos-321 mission, covering homogeneously 94 % of the Earth's surface between 71° north and south latitude.
