Early soviet satellite magnetic field measurements from 1964 and 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.

Both satellites had two measurement devices. The data from Kosmos-312 derives from the device that provided the stronger signal during the time of measurement. In case of Kosmos-49 the devices were switched on and off regularly, resulting in the two herein presented data tables for this mission.
