EXPRESS-AM5

Express-AM5 (also catalogued as Ekspress-AM5, COSPAR designator 2013-077A, NORAD ID 39487) is a Russian geostationary communications satellite owned and operated by the Russian Satellite Communications Company (RSCC). Launched on December 25, 2013, the spacecraft forms part of the long-running Ekspress series of commercial and government communications satellites that have served as a backbone of Russian satellite telecommunications infrastructure. The satellite was built by MDA Space and has a launch mass of 3,358 kg, placing it in the medium-to-large category of commercial geostationary platforms. As of this writing, Express-AM5 remains in orbit, stationed in the geostationary arc above Earth.

Mission and Purpose

Express-AM5 belongs to the Ekspress family of geostationary communications satellites, a series developed to provide Russia and neighboring regions with reliable satellite-based telecommunications services. Satellites in this family have historically supported a broad range of applications, including direct-to-home television broadcasting, broadband internet access, government communications, and telephony across Russia's vast and geographically challenging territory. Russia's sheer size — spanning eleven time zones and encompassing enormous stretches of land far beyond the reach of terrestrial networks — makes geostationary communications satellites a practical necessity rather than a luxury, and the Ekspress series has long played a central role in meeting that need.

RSCC, the designated operator, is a state-controlled enterprise tasked with managing Russia's civil satellite communications infrastructure. The organization oversees a fleet of geostationary satellites providing coverage across Russia, the Commonwealth of Independent States (CIS), and in some cases extending to other regions of Europe, the Middle East, and Asia-Pacific. Express-AM5 fits within this broader operational portfolio.

The specific mission parameters for Express-AM5 — including its assigned orbital slot, transponder configuration, and the precise services it supports — are not recorded in the publicly available satellite catalog entry reviewed here. While the satellite's mission type and current operational status are listed as unknown in the tracking catalog, the general design lineage of the Ekspress-AM series strongly suggests it was intended for multi-band commercial and governmental telecommunications service over Russian territory and adjacent regions.

Orbit and Tracking

Express-AM5 operates in a geostationary orbit, the class of orbit in which a satellite's orbital period closely matches Earth's rotational period, causing the satellite to appear essentially stationary when viewed from the ground. This characteristic makes geostationary satellites ideal for continuous, fixed-footprint communications coverage without the need for ground stations to track a moving target.

The satellite's orbital parameters, as currently recorded, reflect a near-perfect geostationary placement. Its apogee stands at 35,797 km and its perigee at 35,792 km, giving it an essentially circular orbit with a difference of only 5 km between its highest and lowest points. The orbital inclination is 0.0°, confirming that the satellite's orbital plane lies precisely along the equatorial plane — another hallmark of operational geostationary satellites. Its orbital period is 1,436.1 minutes, or just over 23 hours and 56 minutes, which corresponds closely to one sidereal day and is the defining characteristic of a true geostationary orbit.

NORAD tracks Express-AM5 under catalog number 39487. The international designator 2013-077A indicates it was the primary payload of the 77th orbital launch of 2013. For observers and engineers alike, the satellite's fixed apparent position in the sky means that once its longitude slot is known, a suitably equipped ground station can maintain a constant link without active steering.

Design and Operator

Express-AM5 was manufactured by MDA Space, a Canadian aerospace company with extensive experience producing satellite buses and components for both commercial and government customers worldwide. MDA Space is known for contributing to complex, high-capability satellite platforms, and its involvement in the Express-AM5 program reflects the international industrial partnerships that characterize modern satellite development even for state-affiliated programs.

The satellite has a recorded mass of 3,358 kg. In the context of geostationary spacecraft, this places Express-AM5 in a class of substantial commercial platforms capable of hosting a significant complement of transponders and operating over an extended service life. Geostationary satellites in this mass range typically carry sufficient onboard propellant for station-keeping maneuvers over a design lifetime that can span fifteen years or more, though the specific design lifetime for Express-AM5 is not confirmed in the catalog data available here.

The operator, the Russian Satellite Communications Company, is the primary state enterprise responsible for civilian satellite communications in Russia. RSCC manages orbital slots assigned to Russia under international telecommunications union coordination procedures, and it operates its fleet commercially, leasing transponder capacity to broadcasters, internet service providers, and government users. The Ekspress-AM series — of which this satellite is a member — represents one of RSCC's primary product lines for high-capacity service delivery.

Launch and Current Status

Express-AM5 lifted off on December 25, 2013, with launch occurring at 19:00 Eastern Standard Time (00:00 UTC on December 26, 2013). The satellite was launched from Russian territory, consistent with the standard practice for Ekspress-series spacecraft, which have typically been orbited on Russian launch vehicles. The Christmas Day launch placed the spacecraft into its intended geostationary transfer orbit from which it would have subsequently raised itself to the operational geostationary arc using onboard propulsion.

The satellite remains in orbit as of the most recent catalog update and has not undergone atmospheric reentry or decay. Its current orbital parameters — with an apogee and perigee separated by only a few kilometers and an inclination held at 0.0° — indicate that the satellite is, or was recently, being actively maintained through station-keeping operations. Without active station-keeping, a geostationary satellite gradually develops a non-zero inclination and its orbit begins to drift in longitude; the very low inclination recorded here is consistent with a satellite that has been receiving regular north-south station-keeping maneuvers.

The mission status is listed as unknown in the tracking catalog, meaning no definitive operational or non-operational determination has been recorded in the publicly available data reviewed for this article. Whether Express-AM5 is currently providing active service, has been placed in a reduced-operations mode, or has been retired but not yet maneuvered to a graveyard orbit above the geostationary arc cannot be confirmed from the catalog record alone.

Significance and Context

Express-AM5 represents one node in Russia's broader effort to maintain an independent, domestically controlled satellite communications infrastructure. For a country of Russia's geographic scale, the ability to relay signals over remote Siberian territories, Arctic regions, and the Russian Far East — areas where fiber and terrestrial microwave links are often economically or logistically impractical — makes geostationary communications satellites a strategic national asset as much as a commercial one.

The Ekspress-AM series as a whole has faced a complicated history, with earlier satellites in the family suffering from technical anomalies and shortened operational lives, prompting RSCC and Russian space planners to pursue more robust designs and international manufacturing partnerships in subsequent generations. The involvement of MDA Space in Express-AM5's construction is one reflection of that evolution, representing a decision to draw on established international expertise to improve satellite reliability.

The satellite's launch on December 25, 2013, made it one of the final orbital payloads of that calendar year and contributed to what was then an active period of Russian commercial geostationary launches. Its continued presence in the geostationary belt — now more than a decade after launch — demonstrates the longevity typical of well-designed large geostationary platforms, which routinely operate for fifteen years or longer before being retired.

For researchers, engineers, and space-watchers monitoring the geostationary arc, Express-AM5 serves as a representative example of the class of large-body commercial telecommunications satellites that collectively form the dense band of operational and retired spacecraft stationed approximately 35,786 km above Earth's equator. Its tracking data, maintained in the public catalog under NORAD ID 39487, provides a continuous record of its orbital evolution and any station-keeping activity observable in the form of subtle parameter changes over time.
