APSTAR-7

APSTAR-7 is a geostationary communications satellite operated by APT Satellite Holdings, a Hong Kong-based satellite services company, on behalf of the broader Apstar fleet. Launched on 30 March 2012, the spacecraft has served as a vital relay platform for telecommunications, broadcasting, and data services across the Asia-Pacific region and beyond. Cataloged by the United States Space Surveillance Network under NORAD identifier 38107 and internationally designated 2012-013A, the satellite remains in service in geostationary orbit and continues to be tracked by space situational awareness networks worldwide.

Mission and Purpose

APSTAR-7 was conceived and deployed as a direct successor to an earlier spacecraft in the Apstar fleet, replacing the aging Apstar 2R satellite that had been in operation since 1997. By the time APSTAR-7 entered service, its predecessor had been on orbit for roughly fifteen years — a lifespan that, while respectable by the standards of its era, had begun to constrain the operational flexibility and capacity available to APT Satellite Holdings. The introduction of APSTAR-7 allowed the operator to refresh its on-orbit assets and expand service capability across one of the world's most densely populated and communications-hungry regions.

Communications satellites of this class typically provide transponder capacity leased to broadcasters, internet service providers, telecommunications carriers, and government agencies. These services support everything from direct-to-home television distribution and VSAT broadband networks to maritime and aeronautical connectivity. The specific payload configuration of APSTAR-7 — including precise transponder counts, frequency bands, and beam coverage geometries — is not fully detailed in publicly available catalog records, and the mission type is formally listed as unknown in the satellite's official catalog entry. Nevertheless, given the operator's established commercial focus and the satellite's placement in geostationary orbit, its general role as a commercial communications relay platform is consistent with APT Satellite Holdings' operational history and the broader Apstar program's mandate.

APT Satellite Holdings has operated the Apstar system for decades as a commercial enterprise targeting the Asia-Pacific market, providing satellite capacity to customers across China, Southeast Asia, South Asia, the Pacific Islands, and parts of the Middle East and Africa. APSTAR-7 was intended to extend that reach and ensure continuity of service as older assets aged out of operational viability.

Orbit and Tracking

APSTAR-7 occupies a position in geostationary Earth orbit (GEO), the band of space approximately 35,786 kilometers above the equator where an object's orbital period matches the Earth's rotational period. At this altitude, a satellite appears essentially stationary relative to a ground observer, making it ideal for continuous coverage of a fixed geographic footprint — a property that is fundamental to the commercial communications missions such satellites support.

The satellite's current tracked orbital parameters confirm its geostationary classification. Its apogee stands at 35,808 km and its perigee at 35,782 km, placing it in a very nearly circular orbit with minimal eccentricity — a hallmark of a properly stationed geostationary spacecraft. The orbital inclination is recorded at 0.0°, meaning the orbital plane is aligned precisely with the equatorial plane, and the orbital period is 1,436.2 minutes, which corresponds closely to one sidereal day. Together, these figures describe a textbook geostationary configuration.

The satellite was launched on 30 March 2012 and, as of the time this record was compiled, remains in orbit with no reentry or decay date on file. Active geostationary satellites are routinely maintained in their orbital slots through periodic station-keeping maneuvers using onboard propulsion systems, which counteract the gravitational perturbations introduced by the Moon, Sun, and the non-uniform distribution of Earth's mass. When a geostationary satellite is finally retired, operators typically perform a "graveyard" or supersynchronous disposal maneuver, raising the spacecraft into an orbit several hundred kilometers above the geostationary belt to free the valuable slot for future use.

APSTAR-7 carries a cataloged mass of 5,054 kilograms, placing it firmly in the category of large geostationary communications platforms. Satellites of this mass class are generally launched on heavy-lift launch vehicles and may carry substantial fuel reserves to support a long operational lifetime of fifteen years or more in some cases.

Because geostationary objects appear fixed in the sky from any given ground location, they are not typically prime targets for casual visual observation in the way that low Earth orbit satellites are. APSTAR-7 does not appear on standard lists of visually prominent satellites, and a dedicated section on naked-eye spotting is not warranted here.

Design and Operator

APSTAR-7 was designed and manufactured by Thales Alenia Space, the Franco-Italian aerospace company that has produced a large number of commercial geostationary telecommunications satellites for operators worldwide. Thales Alenia Space has an extensive heritage in building large GEO platforms, and satellites produced by the company are in service with operators across Europe, Asia, the Americas, and Africa. The selection of a European manufacturer for a Chinese-operated satellite reflects the globally integrated nature of the commercial satellite industry, in which spacecraft procurement frequently crosses national boundaries based on technical capability, schedule, and commercial terms.

The satellite is registered to China as its owner country and is operated by APT Satellite Holdings, which is headquartered in Hong Kong. APT Satellite Holdings is a publicly listed company with a long history of operating commercial satellite capacity over the Asia-Pacific region. The Apstar brand encompasses multiple generations of satellites, with APSTAR-7 representing one of the more recent additions to a fleet that has evolved substantially since the company's earliest orbital assets entered service in the 1990s.

The specific satellite bus, power generation capacity, design lifetime, and transponder payload details for APSTAR-7 are not confirmed in the publicly available tracking catalog for this spacecraft. What is confirmed is the spacecraft's substantial launch mass of 5,054 kilograms, which is consistent with the large, multi-mission bus platforms that Thales Alenia Space routinely produces for the commercial GEO market. Satellites in this mass range typically accommodate significant solar array area to power large transponder complements and carry considerable propellant loads to sustain many years of on-orbit station-keeping operations.

Significance and Current Status

APSTAR-7's most immediate significance lies in its role as the operational successor to Apstar 2R, effectively bridging one era of APT Satellite Holdings' fleet to the next. The transition from a mid-1990s spacecraft to a 2012-era platform would have brought modernized transponder technology, improved power efficiency, and expanded capacity — all factors that are commercially important in a market where demand for satellite bandwidth has grown steadily alongside the proliferation of broadband services, high-definition broadcasting, and mobile connectivity across the Asia-Pacific.

More broadly, APSTAR-7 represents a data point in the gradual expansion of China-affiliated satellite operators as significant players in the global commercial satellite market. While the spacecraft was manufactured in Europe and draws on the international supply chain that underpins the entire geostationary satellite industry, its operation under a Chinese-affiliated entity and its coverage of a region central to Chinese strategic and commercial interests gives it a place in the wider story of space infrastructure development in the Asia-Pacific.

As of the catalog data available for this entry, APSTAR-7 remains on orbit with no decay or reentry date recorded. This is consistent with an actively operated geostationary satellite, which would be expected to remain in its assigned orbital slot and continue providing service until the end of its operational lifetime, at which point disposal into a graveyard orbit would be the standard procedure. The mission status is not formally categorized in the public catalog record, and no public announcements regarding the satellite's retirement or end-of-life timeline are reflected in the available data.

For researchers, engineers, and satellite enthusiasts using this tracking platform, APSTAR-7's orbital elements provide a stable reference point in the geostationary belt. Its near-zero eccentricity, equatorial inclination, and period closely matching the Earth's rotation are the defining characteristics of this class of spacecraft, and APSTAR-7's parameters demonstrate all three with precision. The satellite can be identified in tracking databases by its NORAD catalog number 38107 or its international designator 2012-013A, both of which uniquely associate it with its 2012 launch and its position as the first payload cataloged from that particular launch event.
