ASTRA 2G

Astra 2G is a commercial geostationary communications satellite operated by SES S.A., the Luxembourg-based satellite services company. Catalogued by the United States Space Surveillance Network under NORAD ID 40364 and internationally identified as 2014-089A, the spacecraft occupies a coveted orbital slot above the equator and forms part of SES's well-established Astra fleet. It was launched in late December 2014 and remains operational in orbit today, contributing to the cluster of satellites that together deliver television, broadband, and data services to audiences primarily across Europe and beyond.

Mission and Purpose

Astra 2G was placed at the Astra 28.2°E orbital position, a slot that has historically been one of the most commercially significant broadcast locations in the geostationary arc. The 28.2°E position is closely associated with direct-to-home television distribution in the United Kingdom and Ireland, where satellite reception dishes have for decades been oriented toward this location. The Astra fleet at this longitude forms a virtual cluster that allows broadcasters and service providers to concentrate their signal capacity and offer viewers a large number of channels through a single fixed dish alignment.

As with other satellites in SES's Astra series, Astra 2G was conceived to reinforce, expand, or replace capacity at this orbital position, ensuring continuity of service as older spacecraft age toward end of life. The satellite carries transponders operating in frequency bands suited to high-volume broadcast and broadband applications, enabling the relay of large quantities of digital television programming, including high-definition and ultra-high-definition content, to millions of households. The specific payload configuration and transponder count for Astra 2G are not publicly detailed in the available catalog data, so individual figures have not been confirmed here.

SES, as the operating company, is among the world's largest satellite operators by fleet size and revenue, managing dozens of satellites from its operational headquarters. The Astra brand specifically has been synonymous with European direct broadcast satellite services since the late 1980s, and successive generations of Astra satellites have been deployed to maintain and grow that footprint. Astra 2G represents one of the more recent additions to the fleet at 28.2°E, helping to sustain the long-term commercial viability of that orbital neighborhood.

Orbit and Tracking

Astra 2G occupies a near-perfect geostationary orbit approximately 35,000 kilometers above Earth's equator. Tracking data places its apogee at 35,816 km and its perigee at 35,774 km, reflecting an orbit of very low eccentricity — the difference between the highest and lowest points of its path is only about 42 kilometers, meaning the satellite traces a nearly circular track around Earth. Its orbital inclination stands at just 0.1 degrees relative to the equatorial plane, an extremely close alignment that is characteristic of well-maintained operational geostationary satellites whose operators actively expend onboard propellant to counteract natural perturbations, particularly those caused by the gravitational influence of the Moon and Sun.

The satellite completes one full revolution around Earth every 1,436.2 minutes — just over 23 hours and 56 minutes — which is essentially synchronous with Earth's rotation period. This near-perfect match between orbital period and Earth's spin means Astra 2G remains effectively stationary when viewed from the ground, hovering persistently above a fixed point on the equator. It is this property that makes geostationary satellites so valuable for broadcast and telecommunications: receiving dishes can be installed and left in a fixed orientation without any need for tracking mechanisms.

Because Astra 2G is a geostationary payload, it does not pass across the sky in the manner of low-Earth orbit satellites. Instead, it sits at a constant elevation and azimuth angle for any given location on Earth's surface. From the United Kingdom, for instance, a dish aimed at the 28.2°E position points toward the southern sky at an elevation that varies depending on the observer's latitude. The satellite is visible to ground observers only with optical aid, given its extreme altitude, and it appears as a slow or essentially stationary point of light relative to the star field.

NORAD catalog entry 40364 is used by space surveillance systems globally to track the spacecraft and distinguish it from the numerous other objects in the geostationary belt. The international designator 2014-089A marks it as the primary payload of the 89th orbital launch of 2014.

Design and Operator

The manufacturer of Astra 2G is not recorded in the publicly available catalog data. SES contracted the satellite's construction as part of a broader fleet renewal and expansion strategy, but specific details about the satellite bus, propulsion system, design lifespan, and onboard mass have not been confirmed in the verified catalog record and are therefore not stated here.

SES S.A. is headquartered in Betzdorf, Luxembourg, and is publicly listed on stock exchanges in both Luxembourg and Paris. The company operates satellites across multiple orbital slots and frequency bands, serving broadcast, government, maritime, aeronautical, and enterprise customers worldwide. The Astra sub-brand focuses on direct-to-home broadcast in Europe, while SES's other orbital assets address a wider variety of applications globally. SES holds the orbital rights and spectrum licenses associated with the 28.2°E position through coordination with the International Telecommunication Union, which manages the global framework for orbital slot assignments.

Astra 2G was launched on 26 December 2014, lifting off from the Baikonur Cosmodrome in Kazakhstan. Baikonur is one of the world's oldest and most active launch facilities, operated under a lease arrangement by Russia and historically the site of many landmark space missions. The rocket delivered Astra 2G into its intended transfer orbit, from which the satellite used its onboard propulsion to raise itself to geostationary altitude. The launch vehicle used for this mission placed the satellite at the intended slot above 28 degrees east longitude, and the spacecraft was formally positioned at that location shortly after launch.

Operational Status and Significance

As of the date of this reference, Astra 2G remains in orbit and has not undergone atmospheric reentry or decommissioning according to catalog records. The satellite continues to be tracked as an active payload at its geostationary position. Whether it is currently transmitting services or has transitioned to a backup or storage status is not confirmed by catalog data, though the satellite's continued presence at its designated slot is consistent with ongoing operational use.

The 28.2°E orbital position served by Astra 2G and its sister spacecraft is frequently cited as one of the most spectrum-dense and commercially active slots in the entire geostationary arc. Dozens of transponders operated by SES at this location collectively deliver hundreds of television channels and data services, and the aggregation of multiple satellites at closely adjacent longitudes — sometimes called a satellite neighborhood or cluster — amplifies the attractiveness of the position for broadcasters and service providers. A single modest receive dish can capture signals from all spacecraft in the cluster simultaneously, making it highly efficient from an end-user infrastructure standpoint.

The deployment of Astra 2G in late 2014 came at a period when European pay-television operators were investing heavily in high-definition content and beginning to plan for ultra-high-definition services. The additional capacity brought by newer spacecraft at 28.2°E supported the bandwidth demands these higher-quality formats impose. In this respect, Astra 2G's arrival was part of a broader technological and commercial transition across the satellite broadcasting industry.

For SES as an organization, each successive Astra satellite also represents an extension of a fleet genealogy stretching back to the earliest days of pan-European commercial broadcasting. The longevity and continuity of the Astra name at key orbital positions reflects sustained investment and the durable economics of geostationary broadcast infrastructure. Astra 2G, as one of the newer members of that family as of its launch date, contributes to ensuring that the 28.2°E position remains well-served with modern, high-capacity assets for the foreseeable future.

How to Observe Astra 2G

Because Astra 2G occupies a geostationary orbit at an altitude of approximately 35,800 km, it does not move across the sky in any visually meaningful way from a ground observer's perspective. It will not produce a pass prediction in the manner of the International Space Station or other low-Earth orbit objects. Instead, it remains fixed at a constant point in the sky corresponding to its equatorial longitude of 28.2°E. From locations in Europe, North Africa, and parts of the Middle East, the satellite sits at a fixed elevation angle in the southern or southwestern sky, depending on the observer's geographic position.

Visual detection without optical instruments is not generally feasible given the satellite's extreme altitude, and even with binoculars or a small telescope it would appear only as a faint, essentially stationary point. Observers with equatorially mounted telescopes and access to precise ephemeris data can locate it by its fixed celestial coordinates. In practice, Astra 2G is most meaningfully "observed" through the television or broadband services it enables rather than through direct visual astronomy.
