HISPASAT 30W-6

HISPASAT 30W-6 is a geostationary communications satellite operated by the Spanish telecommunications company Hispasat. Registered under NORAD catalog ID 43228 and international designator 2018-023A, it was launched on 5 March 2018 and continues to operate in orbit today. Built by Lanteris Space Systems and weighing 6,092 kilograms at launch, it represents a significant element of Spain's commercial satellite communications infrastructure, providing coverage across multiple continents from its position over the Atlantic.

Mission and Purpose

The primary role of HISPASAT 30W-6 is to serve as a multi-purpose communications platform capable of supporting a broad range of telecommunications services. These include direct-to-home television broadcasting, broadband internet connectivity, corporate network links, and other telecommunications applications that require reliable, high-capacity relay from geostationary orbit. This range of services reflects the growing demand placed on modern commercial communications satellites, which must increasingly serve not just traditional broadcast customers but also enterprise users and internet service providers seeking to extend connectivity into underserved or remote areas.

HISPASAT 30W-6 was placed at 30° West longitude in geostationary orbit, a slot that carries considerable strategic value for Hispasat. From this position, the satellite is geometrically well situated to provide coverage reaching across the Iberian Peninsula, the Canary Islands, and significant portions of Latin America and the Atlantic region — a geographic footprint that has historically been central to Hispasat's business model as a company with strong cultural and commercial ties between Europe and the Americas.

One of the defining purposes of this satellite was to replace its predecessor at the 30° West slot, Hispasat 1D, which had been serving that orbital position for many years. The transition to HISPASAT 30W-6 was therefore not merely an expansion of capacity but also a generational upgrade, bringing newer technology and greater throughput to an orbital position already well established within Hispasat's operational fleet. Such slot continuity is common practice in the industry, ensuring that ground infrastructure, uplink facilities, and regulatory coordination built around an orbital position can continue to be leveraged without interruption.

Orbit and Tracking

HISPASAT 30W-6 operates in geostationary Earth orbit, a regime that places it at an altitude where its orbital period closely matches the rotational period of the Earth itself. With an apogee of 35,821 kilometers and a perigee of 35,770 kilometers, the orbit is nearly perfectly circular, as is typical and necessary for a satellite intended to maintain a fixed apparent position over the same point on the equator at all times. Its inclination is recorded at 0.0°, confirming that the orbit lies essentially in the equatorial plane — a defining characteristic of true geostationary orbit.

The orbital period of HISPASAT 30W-6 is 1,436.2 minutes, or approximately 23 hours and 56 minutes. This figure corresponds closely to one sidereal day — the time it takes for the Earth to complete one full rotation relative to the stars rather than the sun — which is precisely why geostationary satellites appear stationary to observers on the ground. From a tracking standpoint, a satellite in this type of orbit does not drift noticeably across the sky as low-Earth orbit objects do; instead, it holds a fixed position in the celestial sphere as seen from any given location on Earth's surface.

This stable geometry makes geostationary satellites like HISPASAT 30W-6 ideally suited for communications applications, since ground antennas can be pointed at a fixed azimuth and elevation without the need for active tracking systems. Fixed dishes on homes, commercial buildings, and broadcast facilities can maintain a permanent link with the satellite, which is central to the economics and practicality of satellite television and broadband services.

The satellite's NORAD ID of 43228 allows it to be tracked and cataloged by space surveillance networks, which monitor its position and periodically update its two-line element sets. As of the time of this article's writing, HISPASAT 30W-6 remains in orbit with no decay or reentry date recorded.

Design and Operator

HISPASAT 30W-6 was manufactured by Lanteris Space Systems and has a launch mass of 6,092 kilograms, placing it firmly in the category of large commercial geostationary satellites. Satellites in this mass range typically carry substantial payload capacity — multiple transponders operating across various frequency bands — along with the onboard power systems, attitude control hardware, and propulsion systems necessary to maintain station-keeping over the course of a multi-year operational life.

A notable design feature of the satellite is its use of four SPT-100 plasma propulsion engines. The SPT-100 is a type of Hall-effect thruster, a form of electric propulsion technology that accelerates ionized propellant using electric and magnetic fields to generate thrust far more efficiently than conventional chemical rockets. While Hall-effect thrusters produce only very small amounts of thrust at any one time, their high specific impulse — meaning they extract far more velocity change per kilogram of propellant consumed — makes them highly valuable for the station-keeping maneuvers that geostationary satellites must perform continuously throughout their operational lives. Without regular small corrections, gravitational perturbations from the Moon, Sun, and Earth's slightly non-uniform gravitational field would gradually cause a geostationary satellite to drift from its assigned slot. By using electric propulsion for these corrections, satellites like HISPASAT 30W-6 can significantly reduce the amount of propellant they must carry, thereby freeing up mass budget for additional payload capacity or extending operational lifespan.

The satellite was launched aboard a Falcon 9 rocket, SpaceX's workhorse commercial launch vehicle, from what was at the time a well-established platform for delivering heavy geostationary payloads to their target orbits. The launch took place on 5 March 2018.

Hispasat itself is a Spanish satellite telecommunications operator with deep roots in the Iberian market. The company has historically played a central role in connecting Spain, Portugal, and their respective communities in Latin America through satellite services, and HISPASAT 30W-6 continues in that tradition by occupying one of the most strategically important slots in the company's orbital portfolio.

Current Status and Significance

As of the latest catalog data, HISPASAT 30W-6 remains operational in geostationary orbit, with no reentry or decay event recorded. Its mission status and precise operational condition are not publicly detailed in the satellite catalog, and specific figures regarding its current health, fuel reserves, or expected end-of-life date are not part of the verified public record available here.

What can be said with confidence is that the satellite occupies a position of genuine significance within Spain's commercial space and telecommunications landscape. Hispasat has long been one of the more prominent satellite operators in the European and Ibero-American market, and the 30° West orbital position represents a key piece of that portfolio. By replacing an aging predecessor at the same slot with a more capable and modernly equipped spacecraft, Hispasat ensured continuity of service while also upgrading its ability to meet growing demand across its coverage area.

From a broader industry perspective, HISPASAT 30W-6 also illustrates several trends that have come to characterize large commercial geostationary satellites in the late 2010s and into the 2020s: the adoption of electric propulsion systems to improve efficiency, the use of commercially available launch vehicles such as the Falcon 9, and the growing expectation that individual satellites must serve multiple market segments simultaneously rather than being designed around a single application. The combination of broadcast, broadband, and corporate network capabilities in a single spacecraft reflects the convergence of telecommunications services that has reshaped the industry over the past two decades.

The satellite's mass of 6,092 kilograms at launch is a testament to the scale of modern commercial geostationary platforms. Spacecraft in this weight class represent substantial investments and are typically designed to operate for fifteen years or more, making each one a long-term strategic asset for its operator. Whether HISPASAT 30W-6 is currently in full commercial service, in a reduced operational mode, or otherwise cannot be confirmed from publicly available catalog data, but its continued presence in orbit underscores the durability of well-constructed geostationary platforms.

For satellite enthusiasts and researchers, HISPASAT 30W-6 can be found in orbital databases under NORAD ID 43228 and COSPAR designator 2018-023A, and its two-line element data is routinely updated to reflect its maintained position near the geostationary arc.
