SPOT 7

SPOT 7, also cataloged under NORAD ID 40053 and international designator 2014-034A, is an Earth observation satellite that has been operating in low Earth orbit since its launch on June 29, 2014. Better known in some contexts by its secondary designation Azersky, the spacecraft occupies a near-circular sun-synchronous orbit and continues to circle the globe as of this writing. The satellite is operated by Airbus DS Geo and is associated with Azerbaijan as its owner country, marking a notable milestone in that nation's engagement with space-based remote sensing infrastructure.

Mission and Purpose

Azersky — the name by which SPOT 7 is known in the context of its Azerbaijani ownership — represents Azerbaijan's first dedicated Earth observation satellite, a distinction that carried considerable symbolic and practical significance for the country's ambitions in the geospatial and remote sensing sectors. Earth observation satellites of this class are designed to capture high-resolution optical imagery of the planet's surface, supporting a wide range of applications including urban planning, agricultural monitoring, environmental assessment, disaster response, and national mapping programs.

The satellite is capable of capturing imagery at a ground resolution of approximately 1.5 meters, placing it firmly within the category of high-resolution commercial remote sensing assets. At that resolution, individual structures, road networks, and land-use patterns become distinguishable, making the data produced by the satellite commercially and strategically valuable. This level of detail is comparable to other members of the SPOT (Satellite Pour l'Observation de la Terre) constellation, a French-originated series of Earth observation satellites that has been central to commercial satellite imagery for decades.

Although the satellite's current mission status is not publicly recorded in the tracking catalog, the SPOT/Azersky platform was built to serve both the commercial imagery market and the specific geospatial needs of Azerbaijan. The arrangement through which Azerbaijan came to own and operate the satellite — under the Azersky designation — reflects a broader trend of nations acquiring dedicated remote sensing capacity either through direct satellite construction programs or through commercial acquisition agreements with established aerospace manufacturers.

Orbit and Tracking

SPOT 7 / Azersky operates in a sun-synchronous orbit (SSO), one of the most common orbital regimes for Earth observation missions. Sun-synchronous orbits are engineered so that the satellite passes over any given location on Earth at approximately the same local solar time on each revisit. This consistency is critically important for remote sensing work: because the sun angle remains roughly constant from one pass to the next, images acquired on different dates can be compared with greater reliability, minimizing the confounding effects of varying illumination on the analysis of surface changes over time.

The satellite's orbit is nearly circular, with an apogee of 695 kilometers and a perigee of 693 kilometers, yielding an altitude difference of only 2 kilometers between the highest and lowest points of each pass. This tight margin confirms that the orbit is exceptionally well-maintained and close to perfectly circular. The orbital inclination is 98.1 degrees relative to the equatorial plane, a value slightly beyond 90 degrees that is characteristic of retrograde sun-synchronous orbits — the satellite travels in a direction slightly counter to Earth's rotation, which is precisely what allows the orbital plane to precess in step with Earth's movement around the sun.

Each orbit takes approximately 98.5 minutes to complete, meaning the satellite circles Earth roughly 14 to 15 times per day. At an altitude of roughly 694 kilometers, SPOT 7 / Azersky moves at a velocity of several kilometers per second relative to the ground, sweeping its imaging instruments across successive ground tracks on each pass. The combination of orbital altitude, inclination, and period ensures broad global coverage and regular revisit times, both desirable qualities for an Earth observation platform.

For observers and analysts using satellite tracking tools, the satellite can be located using its NORAD catalog ID 40053 or its COSPAR international designator 2014-034A. These identifiers are the authoritative references used by tracking networks worldwide to distinguish this object from the thousands of other cataloged objects in Earth orbit.

Design and Operator

SPOT 7 / Azersky was manufactured by Space Systems and has a recorded mass of 712 kilograms, placing it in the medium-class range for Earth observation satellites. At that mass, the spacecraft is substantial enough to carry meaningful optical instrumentation while still being manageable in terms of launch vehicle requirements and orbital insertion complexity.

The satellite is operated by Airbus DS Geo, the geospatial data division of Airbus Defence and Space, one of Europe's foremost aerospace and defense manufacturers. Airbus DS Geo has long been involved in the commercial satellite imagery market, managing constellations and data services for governmental and commercial clients globally. The SPOT program itself has been one of the flagship remote sensing initiatives in commercial satellite history, tracing its origins back to the 1980s and evolving through successive generations of spacecraft with increasingly capable sensors.

The SPOT series, of which SPOT 7 is a later member, was designed with a modular and iterative philosophy, each new generation improving upon the resolution, revisit time, and data throughput of its predecessors. By the time SPOT 7 was developed, the platform had matured considerably, incorporating advances in optical design, onboard data handling, and ground segment compatibility. SPOT 7's 1.5-meter resolution capability reflects this evolution, representing a significant improvement over earlier generations of the series.

The dual naming convention — SPOT 7 within the manufacturer and operator's fleet designation, and Azersky in the context of its Azerbaijani ownership — is not unusual in the commercial satellite industry. Satellites are sometimes sold or leased to sovereign operators while retaining their original series designation in tracking databases and technical documentation, allowing continuity in orbital management and historical records even as commercial arrangements shift.

Significance and Legacy

The acquisition of Azersky placed Azerbaijan among a growing cohort of nations that have invested in dedicated space-based Earth observation capability. For a country of Azerbaijan's size, operating a satellite with 1.5-meter resolution imagery capacity represents a meaningful step toward geospatial sovereignty — the ability to independently acquire detailed imagery of territory and regions of interest without reliance solely on third-party commercial providers.

Earth observation satellites have become foundational tools for national governance and development planning. From monitoring agricultural output across large territories to tracking urban expansion, assessing the aftermath of natural disasters, or supporting national security and border monitoring applications, the data produced by a high-resolution satellite like Azersky has wide-ranging utility. Azerbaijan's investment in this capability, formalized through its ownership of the satellite under the Azersky name, signals an awareness of the strategic value that space assets increasingly represent for mid-sized nations.

Within the broader context of the SPOT program, SPOT 7 / Azersky is one of the later additions to a lineage that has made an outsized contribution to the development of commercial satellite imagery as an industry. The SPOT series helped establish the commercial viability of selling remotely sensed Earth imagery before the market became as crowded and competitive as it is today, and later members of the series like SPOT 7 have built on that heritage with substantially improved technical capabilities.

The satellite remains in orbit as of the current catalog update, with no decay or reentry date recorded. Its near-circular orbit at roughly 694 kilometers altitude is well above the altitude range where atmospheric drag causes rapid orbital decay, suggesting the platform has considerable remaining orbital lifetime under normal conditions, contingent on any onboard propulsion being used for station-keeping as required.

How to Spot It

SPOT 7 / Azersky is a medium-sized spacecraft at approximately 712 kilograms and orbiting at around 694 kilometers altitude, which means it is theoretically visible to the naked eye under favorable conditions, much like many other satellites in similar low Earth orbits. Observers on the ground may be able to see the satellite as a steadily moving point of light crossing the sky during twilight hours — shortly after sunset or before sunrise — when the satellite is illuminated by sunlight while the observer is in darkness.

To find a visible pass opportunity, use the NORAD ID 40053 in any compatible satellite tracking application or pass prediction tool. The satellite's 98.5-minute orbital period means multiple passes may be observable on a given night from mid- and high-latitude locations, given the 98.1-degree inclination that carries its ground track across virtually all latitudes on Earth. Passes that climb high in the sky — above 40 or 50 degrees elevation — will generally appear brighter and easier to follow than low, grazing passes near the horizon.
