The USSR launched Meteor-1-1 as its first fully operational Meteor weather satellite. It was designed for near-global observations to support day-to-day forecasting, including cloud cover and ice/snow monitoring. This launch marked the start of Meteor as an operational satellite system rather than a set of prototypes.
The Soviet Military Industrial Commission (VPK) ordered development of GMKS, a “Unified Hydro and Meteorological Space System.” The intent was to organize satellites, ground stations, and data distribution into a coordinated system for weather and related environmental monitoring. This helped push Meteor toward larger, networked operations.
A dedicated production line for Meteor satellites was set up at VNIIEM’s Istra branch. Moving from small-batch work to a production line supported more frequent launches and more standardized spacecraft. This change was important for keeping a steady stream of satellites in orbit for routine weather coverage.
The first Meteor-Priroda spacecraft was launched into a near-polar orbit. Meteor-Priroda expanded Meteor’s role beyond basic weather imaging toward broader Earth observation, including multi-spectral measurements (observations in multiple wavelength bands). This helped connect meteorology with resource and environmental monitoring applications.
The first Meteor-2 satellite was launched, starting flight testing of the second-generation system. Meteor-2 built on Meteor-1 with improved instruments and a higher operating orbit, supporting more capable weather observations. This step began the transition from the initial operational system to a more modern replacement.
Meteor-Priroda was declared operational, formalizing it as a working part of the Soviet Earth-observation effort. This milestone reflects the program’s move from trial flights to routine service, with regular data for civil and scientific users. Operational status also implied stable ground processing and distribution workflows.
Meteor satellite imagery helped identify areas of thinner sea ice for the icebreaker Sibir during a pioneering Arctic transit from Murmansk toward the Bering Strait. This demonstrated how satellite-based Earth observation could support real-world navigation and operations in difficult environments. It also highlighted the value of routinely delivered satellite data, not just research images.
The USSR declared the Meteor-2 network operational, indicating the system had reached a level of coverage and reliability suitable for routine forecasting support. A declared network typically meant satellites, ground stations, and data delivery were integrated for sustained service. This was a key “steady-state” moment for Soviet meteorological satellite operations in the 1980s.
Kosmos 1484, a Resurs-OE prototype Earth-imaging satellite, was launched using a spacecraft bus derived from Meteor. This shows how Meteor hardware and experience fed into broader Earth-observation systems beyond weather, including imaging for resources and mapping. It reflects a wider Soviet trend: reusing proven satellite platforms to speed development of new applications.
The first Meteor-3 spacecraft was launched as Kosmos 1612. Meteor-3 represented a third generation, aiming for improved sensing and different orbital choices to enhance coverage. Early Meteor-3 development was difficult, and the initial launch did not achieve its intended results, underscoring the challenges of upgrading an operational satellite system.
Meteor-3-1 was launched as the first “official” Meteor-3 mission after the earlier attempt. This step helped restart momentum toward a functioning third-generation system. Meteor-3’s higher orbit and updated instruments aimed to improve how much of Earth could be observed in each pass and to refine weather-related measurements.
Meteor-3-4 launched in April 1991, the last Meteor-family launch before the USSR dissolved later that year. By this point, the Meteor program had evolved from basic weather imaging (Meteor-1) into a wider Earth-observation and meteorology infrastructure that also supported international payload cooperation. The Soviet Union’s collapse in December 1991 reshaped funding, institutions, and program ownership, marking a clear transition point for Meteor’s Soviet-era phase.
