EXPRESS-AT2

EXPRESS-AT2 (also cataloged under its Russian designation Ekspress-AT2) is a geostationary communications satellite operated by the Russian Satellite Communications Company (RSCC) and built by JSC Information Satellite Systems Reshetnev, one of Russia's leading spacecraft manufacturers. Launched in March 2014, it forms part of the long-running Ekspress family of Russian communications satellites, a series that has served as a backbone of domestic and regional telecommunications infrastructure for decades. The satellite carries the NORAD catalog identifier 39613 and the international COSPAR designator 2014-010B, and as of the current catalog date it remains in active orbit.

Mission and Purpose

EXPRESS-AT2 was lofted into geostationary orbit on March 14, 2014, as part of a broader Russian effort to modernize and expand the country's satellite communications capacity through the Ekspress program. The RSCC, a state-controlled enterprise responsible for managing Russia's civil satellite communications infrastructure, relies on the Ekspress constellation to deliver broadcasting, broadband, and telecommunications services across the vast geographic span of the Russian Federation and neighboring regions.

The "AT" designation within the Ekspress family is generally associated with satellites configured for direct-to-home television broadcasting and related services, distinguishing them from other variants in the series intended primarily for trunk telecommunications or data relay. Russia's enormous east-to-west extent makes geostationary satellites particularly valuable for uniform national coverage, as terrestrial and even low-orbit solutions struggle to provide consistent service across all time zones and latitudes simultaneously.

Specific details about the precise payload configuration of EXPRESS-AT2 — including the number of transponders, frequency bands, and exact coverage footprint — are not recorded in the publicly available orbital catalog. The satellite's mission type is listed as unknown in current tracking records, and its operational status is similarly not confirmed through catalogued data. Nevertheless, its membership in the RSCC fleet and its placement in geostationary orbit are consistent with a communications role serving Russian and regional customers.

Orbit and Tracking

EXPRESS-AT2 occupies a position in geostationary Earth orbit (GEO), the specialized orbital regime approximately 35,786 kilometers above the equator where a satellite's orbital period matches the Earth's rotational period, causing it to appear stationary relative to a fixed point on the ground. This characteristic makes geostationary orbit uniquely suited to communications and broadcasting applications, since ground-based antennas can point at a fixed position in the sky without requiring tracking systems.

The orbital data for EXPRESS-AT2 confirms its placement in this regime with considerable precision. Its apogee stands at 35,796 km and its perigee at 35,794 km, a difference of only 2 km that reflects an orbit of remarkably low eccentricity — essentially circular. The orbital inclination is recorded at 0.0°, meaning the satellite tracks almost exactly above the equatorial plane, as expected for an operational geostationary spacecraft. Its orbital period is 1,436.2 minutes, very close to the roughly 1,436-minute sidereal day, confirming its geosynchronous timing.

The satellite's near-zero inclination and near-circular orbit are the products of active station-keeping maneuvers conducted by ground operators. Geostationary satellites naturally drift from their assigned orbital slots over time due to gravitational perturbations from the Moon and Sun, as well as the non-uniform distribution of Earth's mass. Onboard propulsion systems counteract these forces, maintaining the satellite's position within tightly defined tolerances stipulated by international orbital slot agreements administered through the International Telecommunication Union. The extremely close apogee and perigee values in EXPRESS-AT2's current catalog entry suggest that these station-keeping operations have been effective in maintaining a well-circularized orbit.

For tracking purposes, EXPRESS-AT2 is monitored by the United States Space Surveillance Network and maintained in the publicly accessible orbital catalog under NORAD ID 39613. Because geostationary satellites appear essentially fixed relative to the Earth's surface, their tracking presents different challenges than low-orbit objects: rather than sweeping passes across the sky, they occupy a single point on the geostationary arc as seen from any given location. The satellite launched as part of the launch event identified by the COSPAR designator 2014-010B, indicating it was the second payload associated with the tenth launch of 2014 in the international registry.

Design and Operator

EXPRESS-AT2 was designed and manufactured by JSC Information Satellite Systems Reshetnev, headquartered in Zheleznogorsk, Krasnoyarsk Krai, Russia. Reshetnev (also written as Reshetnev ISS or ISS Reshetnev) is among the most prolific manufacturers of Russian communications and navigation satellites, with a heritage that includes the GLONASS navigation constellation and numerous Ekspress-series platforms. The company has long served as the primary industrial partner for RSCC satellite procurements.

The spacecraft has a recorded mass of 1,326 kg, placing it in the medium-weight class of geostationary communications satellites. This figure most likely represents the satellite's launch mass or on-orbit dry mass as recorded in the catalog; communications satellites of this class typically carry a significant proportion of their mass as propellant to support both the apogee insertion burn (if applicable) and years of on-orbit station-keeping. The specific bus architecture and payload details are not documented in the public catalog record.

The Russian Satellite Communications Company itself operates as an open joint-stock company with the Russian government holding a controlling interest. As the national operator of civil satellite communications capacity, RSCC manages orbital slots registered to Russia and provides capacity to broadcasters, internet service providers, and telecommunications carriers. The Ekspress series represents RSCC's primary fleet, with satellites constructed by domestic manufacturers like Reshetnev and occasionally incorporating components from international aerospace suppliers.

Current Status and Legacy

As of the catalog data reflected here, EXPRESS-AT2 remains in orbit with no decay or reentry date recorded, consistent with normal operations for an active or retired geostationary satellite. Geostationary satellites that reach the end of their operational service lives are typically raised into a "graveyard" or disposal orbit several hundred kilometers above the geostationary belt, where they pose no interference risk to active spacecraft. Whether EXPRESS-AT2 is actively providing service, has been placed in a reserve capacity, or has been retired to a disposal orbit is not specified in the publicly available catalog entry.

The Ekspress program as a whole reflects Russia's sustained investment in national satellite communications sovereignty — the desire to maintain independent, domestically operated infrastructure for broadcasting and telecommunications rather than relying on foreign satellite capacity. For a country spanning eleven time zones and containing vast regions where terrestrial broadband and cable infrastructure are impractical, geostationary satellites serve a critical social and economic function, delivering television signals, voice communications, and data connectivity to remote communities in Siberia, the Far East, and the Arctic fringe.

EXPRESS-AT2's place in this legacy is as one component of a broader constellation effort. Its launch in 2014 came during a period of active fleet renewal for RSCC, as older Soviet-era and early post-Soviet satellites were replaced with newer platforms. The partnership between RSCC and Reshetnev for domestic satellite manufacturing has been central to maintaining Russian industrial capabilities in spacecraft construction, sustaining expertise across a supply chain that feeds into both commercial and government space programs.

The satellite's orbital parameters — a circular equatorial orbit at geostationary altitude with a 1,436.2-minute period — are expected to remain essentially stable as long as station-keeping operations continue. If and when the spacecraft is eventually retired, standard international guidelines would call for its removal to a disposal orbit above the protected geostationary band, clearing its orbital slot for future use by successor satellites.

Observability

EXPRESS-AT2 is not considered a visually notable object for amateur observers. Geostationary satellites at approximately 35,795 km altitude are, by virtue of their extreme distance, far dimmer than objects in low Earth orbit even when the geometry is favorable. They do not produce the swift, bright passes characteristic of large low-orbit spacecraft; instead, they appear as extremely faint, essentially stationary points of light in the sky, indistinguishable to the naked eye under any normal observing conditions. Dedicated amateur astronomers equipped with telescopes and using precise ephemeris data derived from the NORAD catalog entry can in principle locate EXPRESS-AT2 on the geostationary arc, but this requires significant equipment and skill. The satellite is not listed among objects commonly targeted for casual naked-eye observation.
