About YAMAL 300K

Yamal-300K is a Russian geostationary communications satellite operated by Gazprom Space Systems and constructed by JSC Information Satellite Systems Reshetnev (ISS Reshetnev). Launched on November 1, 2012, it carries the NORAD catalog identifier 38978 and the international designator 2012-061B. The satellite provides C-band and Ku-band telecommunications services and remains operational in a near-perfect geostationary orbit above the equator. Its arrival in orbit marked a notable shift in the Yamal satellite program's choice of manufacturers, reflecting broader changes in the Russian commercial satellite industry.

Mission and Purpose

Yamal-300K was developed to extend and reinforce the communications capacity of Gazprom Space Systems, the satellite subsidiary of the Russian energy giant Gazprom. The satellite carries a communications payload supplied by Thales Alenia Space, comprising eight C-band transponders and eighteen Ku-band transponders, each operating with a bandwidth of 72 MHz, for a combined equivalent of 52 transponders at the standard 36 MHz reference bandwidth. Transmitted power reaches 110 watts in C-band and 140 watts in Ku-band, enabling the satellite to deliver television broadcasting, broadband internet, corporate data links, and other telecommunications services across its coverage footprint.

The Yamal program has historically been central to Russia's commercial satellite telecommunications infrastructure, providing connectivity to regions including Siberia and other parts of the Russian Federation that are difficult to serve through terrestrial networks. Yamal-300K fits within that broader mission, supplementing earlier Yamal satellites and helping to sustain service continuity while newer platforms were under development. Although the specific mission objectives and the current operational status of the satellite are not formally recorded in public tracking catalogs, its design life and payload configuration clearly position it as a commercial broadband and broadcast communications platform.

Orbit and Tracking

Yamal-300K occupies a geostationary orbit, the class of orbit in which a satellite matches Earth's rotational period and thus appears stationary relative to a fixed point on the ground below. This characteristic makes geostationary satellites especially suitable for telecommunications applications, since ground-based antennas can be pointed at a fixed location in the sky without the need for continuous tracking adjustments.

The satellite's orbital parameters reflect a very well-maintained station. Its apogee stands at 35,799 km and its perigee at 35,792 km, a difference of only 7 km, indicating an orbit that is very nearly circular. Its inclination is recorded at 0.0°, confirming that it remains precisely aligned with the equatorial plane — the hallmark of a well-controlled geostationary slot. Its orbital period is 1,436.2 minutes, closely matching the length of one Earth sidereal day and confirming its synchronous character. As of the time of writing, Yamal-300K remains in orbit and has not undergone any recorded reentry or decay event.

Tracking data for Yamal-300K is maintained through the standard NORAD two-line element (TLE) catalog and updated regularly. Because it is a payload object — not a rocket body or debris fragment — it is tracked as a primary cataloged object. Observers using satellite-tracking software can locate the satellite at the geostationary arc using its NORAD ID of 38978 or its COSPAR designator 2012-061B.

Design and Operator

Yamal-300K was manufactured by ISS Reshetnev, a Russian satellite manufacturer based in Zheleznogorsk (formerly Krasnoyarsk-26) that specializes in building spacecraft for geostationary and other high-orbit applications. The satellite was built on ISS Reshetnev's Ekspress-1000 platform, an unpressurized bus designed specifically for direct injection into geostationary orbit without the need for a dedicated apogee engine stage aboard the satellite itself. The bus generates 5.6 kilowatts of electrical power and was designed with a service life of fourteen years, meaning the satellite was built to remain operational into the mid-2020s under nominal conditions.

The satellite has a launch mass of 1,870 kg, placing it in the medium-capacity class of geostationary spacecraft. While larger than some regional fixed-service satellites, it is considerably smaller than the heaviest commercial platforms that entered service around the same period. The Ekspress-1000 bus offers a relatively efficient design envelope for its power class, and its unpressurized architecture simplifies some aspects of thermal management and integration.

The communications payload itself was delivered by Thales Alenia Space, a European aerospace manufacturer with significant experience in satellite transponder systems. This international division of labor — Russian bus, European payload — is consistent with practices seen across the Russian commercial satellite sector in the years surrounding Yamal-300K's development, when Western payload technology was regularly integrated with domestically produced satellite platforms. Gazprom Space Systems, as the operating entity, is responsible for managing the satellite's on-orbit resources and providing service to its customers.

Significance and Program Context

Yamal-300K holds particular significance within the history of the Yamal satellite program because it represented a departure from the program's established supplier relationships. The preceding generation of Yamal satellites had been built by RSC Energia, the prominent Russian space and rocket company. However, disagreements between Gazprom Space Systems and RSC Energia over both the cost and the delivery schedule of two planned satellites — Yamal-301 and Yamal-302 — ultimately led Gazprom Space Systems to seek an alternative supplier. ISS Reshetnev was selected to fill that role, and Yamal-300K became the first satellite in the Yamal program to be delivered by a manufacturer other than RSC Energia.

This switch had broader implications for the Russian satellite industry. ISS Reshetnev, already well-established as the manufacturer of Russia's governmental and military communication satellites, gained a commercially significant contract, while RSC Energia's position in the commercial satellite market was weakened. The episode illustrated the competitive pressures and scheduling challenges that were characteristic of the Russian satellite industry during this period, as domestic operators increasingly weighed their options and, in some cases, turned to international alternatives.

The satellite was launched on November 1, 2012, as part of a rideshare mission designated 2012-061, of which Yamal-300K was the secondary payload (hence the "B" suffix in the COSPAR identifier). Its co-passenger on the mission shared the launch vehicle, a common arrangement for geostationary orbit insertion missions when payload mass allows for a dual-manifest configuration.

Since entering service, Yamal-300K has contributed to Gazprom Space Systems' orbital fleet, which serves commercial, governmental, and broadcasting customers. Its C-band capacity is well-suited to wide-area regional coverage and is less susceptible to rain fade than Ku-band, while the Ku-band complement supports higher-throughput applications including direct-to-home broadcasting and enterprise connectivity. Together, the two frequency bands allow the satellite to serve a diverse range of customer applications from a single orbital platform.

The satellite's operational and mission status are not formally recorded in the public tracking catalog, and no detailed official statements about its current service configuration are reflected in available reference data. It continues to appear as an active cataloged payload in orbital databases and has not been reported as decommissioned or relocated to a graveyard orbit.

Current Status and Tracking Notes

Yamal-300K remains a tracked object in the geostationary belt as of current catalog records. Its orbital elements show no indication of significant drift from the equatorial plane, with its inclination holding at 0.0° and its orbit remaining very nearly circular. These characteristics are consistent with a satellite that is receiving regular station-keeping maneuvers — the controlled thruster firings that geostationary operators use to compensate for gravitational perturbations from the Moon, Sun, and Earth's equatorial bulge.

Because geostationary satellites do not move appreciably across the sky as seen from the ground, Yamal-300K is not a target of interest for casual visual observers in the way that low-Earth-orbit satellites such as the International Space Station or large rocket bodies might be. It appears essentially fixed at one point in the sky, and at its orbital altitude of approximately 35,795 km it reflects very little sunlight and is not visible to the naked eye. Dedicated observers using optical telescopes or radio tracking equipment, however, can confirm its presence in the geostationary arc using the published tracking data associated with NORAD ID 38978.

For users of satellite-tracking services, the object can be found under its catalog name YAMAL 300K or the common form Yamal-300K, with the COSPAR identifier 2012-061B serving as an unambiguous international reference across tracking databases worldwide.
