ARABSAT-5A

Arabsat-5A (NORAD catalog ID 36745, international designator 2010-032B) is a geostationary communications satellite operated by the Arab Satellite Communications Organization, commonly known as Arabsat. Launched on 25 June 2010, the spacecraft was placed into a near-equatorial geostationary orbit from which it provides telecommunications services across a broad footprint spanning the Arabian Peninsula, much of Africa, and parts of Europe. It remains in operation as of the most recently updated catalog data, stationed in a stable position consistent with commercial broadcasting and telecommunications use.

Mission and Purpose

The primary function of Arabsat-5A is to serve as a telecommunications relay platform, delivering television broadcasting, internet connectivity, and telephone services to subscribers and operators throughout its coverage region. These three pillars of modern communications infrastructure — broadcasting, broadband data, and voice — represent the core commercial mission that geostationary satellites of this class are typically built around.

The satellite's service territory reflects Arabsat's broader mandate as a regional communications organization. Its footprint encompasses not only the Arabian Peninsula, the heartland of the organization's membership base, but also extends south and west across the African continent and reaches northward into European reception zones. This wide arc of coverage makes Arabsat-5A a valuable asset for broadcasters, internet service providers, and telecommunications carriers seeking to offer connectivity across regions that, in many cases, are underserved by terrestrial infrastructure.

Television distribution has historically been among the most commercially significant uses for geostationary satellites serving this region, with direct-to-home broadcasting representing a large share of satellite capacity demand across the Middle East and North Africa. In addition to entertainment and news broadcasting, satellites in this orbital position are routinely employed for educational broadcasting, government communications, and emergency telecommunications — roles that, while not specifically documented in the public catalog entry for Arabsat-5A, reflect the standard operational profile of spacecraft in this class.

The specific mission status of Arabsat-5A is not detailed in the current catalog record, and any finer-grained description of its operational condition, current transponder utilization, or service contracts would require reference to information beyond what is publicly verified in the tracking catalog.

Orbit and Tracking

Arabsat-5A occupies a geostationary orbit with an apogee of 35,818 km and a perigee of 35,772 km above Earth's surface. The relatively small difference between these two figures — a spread of only 46 km — indicates that the satellite is operating in a nearly circular orbit, as would be expected for an operational geostationary spacecraft. Its orbital inclination is just 0.1°, placing it almost exactly over the equatorial plane. The orbital period is 1,436.2 minutes, which is closely matched to Earth's own rotation period and is what defines the geostationary characteristic: from the surface, the satellite appears to remain essentially fixed in the sky.

This type of orbit, classified broadly as GEO (geostationary Earth orbit), is situated roughly 35,786 km above the equator — the altitude at which an object's orbital velocity naturally synchronizes with Earth's spin. By parking at this altitude with near-zero inclination, Arabsat-5A holds a consistent position in the sky as seen from ground-based antennas, allowing fixed dish installations to maintain a stable link without needing active tracking systems. This is the defining advantage of geostationary orbit for commercial communications: it eliminates the need for complicated steerable antenna arrays on the receiving end.

For satellite trackers and enthusiasts using LowEarth, Arabsat-5A can be located by its NORAD ID 36745 or its COSPAR designator 2010-032B. Because geostationary satellites move with the Earth, their apparent motion in the sky is negligible — they do not pass overhead in the conventional sense that low-Earth-orbit objects do. Instead, observers at a given location will always find Arabsat-5A at the same fixed azimuth and elevation, determined by the observer's geographic coordinates and the satellite's geostationary longitude. Precise positional data for Arabsat-5A is available through the tracking tools on this site.

It is worth noting that geostationary objects, while individually stationary in appearance, are part of a densely populated orbital band. The geostationary belt is an internationally managed resource, with slot assignments coordinated through the International Telecommunication Union to prevent interference between neighboring satellites.

Design and Operator

The Arab Satellite Communications Organization — Arabsat — is a satellite operator headquartered in Riyadh, Saudi Arabia, and is owned collectively by member states of the Arab League. Founded in the 1970s with the goal of establishing an independent Arab regional satellite communications system, Arabsat has grown over the decades into one of the more significant telecommunications satellite operators serving the Middle East and North Africa region. Arabsat-5A is listed in the catalog with Saudi Arabia as the owner country, consistent with Arabsat's headquarters and primary governance structure.

The manufacturer of Arabsat-5A is not recorded in the current tracking catalog, so no claims can be made here about the spacecraft bus, construction heritage, or specific technical specifications. Similarly, the satellite's mass is not publicly available in the verified catalog record. What is known is that the spacecraft falls under the payload classification in tracking databases — meaning it is the primary operational object from its launch event, as opposed to a rocket body or debris fragment.

Arabsat-5A was launched on 25 June 2010. The satellite was assigned the international designator 2010-032B, indicating it was the second cataloged object from the 32nd launch of 2010 as tracked by the international space object registration system. This designator provides a permanent, internationally recognized identifier for the object separate from the NORAD catalog number used in day-to-day tracking operations.

Significance and Current Status

Arabsat-5A represents part of Arabsat's sustained effort to expand and modernize its fleet of geostationary telecommunications spacecraft. The launch in June 2010 came during a period of significant investment by regional satellite operators, as demand for direct-to-home television services and broadband internet continued to grow across the Middle East and African markets.

The satellite continues to orbit Earth as of the most recent data in the tracking catalog — it has not decayed or reentered the atmosphere, and there is no recorded decommissioning date. Geostationary satellites at this altitude are far too high for atmospheric drag to cause orbital decay on any human-relevant timescale. When commercial spacecraft in this region of space reach the end of their operational lives, they are typically maneuvered into a higher "graveyard" orbit a few hundred kilometers above the geostationary belt, preserving the valuable GEO slot for future use and reducing the risk of collision or interference with active satellites.

Whether Arabsat-5A is currently active, in standby, or otherwise disposed of is not specified in the catalog record available here. Its continued presence in the catalog confirms that it remains a tracked, cataloged object in geostationary orbit with no recorded reentry.

From a regional communications perspective, Arabsat-5A and spacecraft like it play a structural role in the telecommunications infrastructure of countries that may have limited or uneven terrestrial broadband and broadcasting networks. The ability to deliver television signals, broadband data, and voice services simultaneously across a continent-spanning footprint from a single geostationary position is a capability that remains commercially and socially relevant across much of the satellite's service region.

The 5A designation within the Arabsat fleet name sequence reflects Arabsat's iterative approach to fleet development, building successive generations of spacecraft to expand capacity and replace aging infrastructure. While the specific relationship between Arabsat-5A and other satellites in the broader Arabsat fleet is a matter of the organization's own program history, the naming convention is indicative of an ongoing, multi-satellite program designed to ensure service continuity over time.

For researchers, communications professionals, and satellite enthusiasts tracking the geostationary belt, Arabsat-5A serves as a representative example of the type of mid-career commercial communications satellite that quietly underpins broadcasting and internet services for hundreds of millions of people across three continents. Its orbital parameters remain stable, its position fixed relative to the Earth below, and its catalog record accessible through the standard international tracking frameworks that govern the transparency and safety of Earth's increasingly crowded orbital environment.
