DUBAISAT-1

DubaiSat-1 is an Earth observation satellite operated by the Mohammed bin Rashid Space Centre (MBRSC) of the United Arab Emirates. Launched on July 28, 2009, it represents one of the earliest milestones in the UAE's effort to develop an indigenous space capability, combining international technical partnership with domestic institutional ambition. The satellite continues to orbit Earth today, catalogued by the United States Space Surveillance Network under NORAD ID 35682 and international designator 2009-041B.

Mission and Purpose

DubaiSat-1 was developed primarily as a remote sensing platform, designed to capture imagery of Earth's surface from low orbit. Remote sensing satellites of this class serve a wide range of civil and governmental purposes, including urban planning, environmental monitoring, agricultural assessment, border surveillance, and disaster response. For the UAE, a nation whose land area encompasses both densely developed coastal cities and expansive desert interior, access to reliable overhead imagery carries particular practical value.

Beyond its direct imaging utility, the mission carried a strong capacity-building dimension. The project was structured not simply as a procurement exercise — buying a finished satellite from an overseas vendor — but as a collaborative development effort intended to transfer technical knowledge to Emirati engineers and scientists. This approach reflected a broader policy priority within the UAE: to establish the foundations of a sustainable national space industry rather than remain dependent on foreign providers indefinitely. The involvement of MBRSC as operator placed institutional ownership of the satellite firmly within the UAE's governmental framework, giving the country direct operational experience with a space asset of its own.

The specific details of DubaiSat-1's imaging capabilities, resolution specifications, and sensor suite are not comprehensively recorded in publicly available catalog data, and the mission type is not formally classified in the satellite registry used by this site. What is well established, however, is that the satellite belongs to the category of medium-resolution Earth observation spacecraft that were increasingly common in the late 2000s as smaller space agencies and emerging space nations began entering the field.

Orbit and Tracking

DubaiSat-1 operates in a sun-synchronous orbit (SSO), a particularly useful orbital regime for Earth observation missions. A sun-synchronous orbit is engineered so that the satellite passes over any given point on Earth's surface at approximately the same local solar time on each successive visit. This consistency in lighting conditions is highly advantageous for optical imaging, since it means that shadows, sun angles, and illumination remain comparable across images taken on different dates — a critical factor when analysts are trying to detect changes in land use, vegetation cover, infrastructure, or other surface features over time.

The satellite's orbital parameters reflect a well-maintained low Earth orbit. Its apogee stands at approximately 657 km and its perigee at approximately 641 km, giving it a nearly circular profile with very little eccentricity. The orbit is inclined at 98.0° to the equatorial plane, which is characteristic of sun-synchronous trajectories — inclinations slightly beyond 90° are necessary to produce the retrograde precession that keeps the orbital plane aligned with the Sun throughout the year as Earth moves around it. DubaiSat-1 completes one full orbit of Earth in approximately 97.6 minutes, meaning it circles the planet roughly fourteen to fifteen times per day.

At an altitude of roughly 650 km, the satellite is well within the low Earth orbit band, which extends from a few hundred kilometers up to approximately 2,000 km. Objects at this altitude are subject to residual atmospheric drag, though at 650 km the atmosphere is extremely thin and orbital decay is a slow process. DubaiSat-1 has remained in orbit continuously since its launch in 2009 and shows no sign of imminent reentry based on current tracking data.

The satellite is tracked continuously by ground-based radar and optical sensor networks and its orbital elements are regularly updated in public databases. Observers and researchers can use its NORAD catalog number, 35682, to retrieve current two-line element sets (TLEs) and predict its ground track and visibility windows with standard satellite tracking software.

Design and Operator

DubaiSat-1 was built through a collaborative arrangement between the Mohammed bin Rashid Space Centre and Satrec Initiative, a satellite manufacturing company based in South Korea. Satrec Initiative has a well-established reputation in the development of small to medium-sized Earth observation satellites, and its involvement provided the MBRSC team with access to proven spacecraft engineering expertise. The partnership was structured to ensure that Emirati engineers participated directly in the design and integration process, giving them hands-on experience that could be applied to future missions.

The Mohammed bin Rashid Space Centre, named after the ruler of Dubai and Prime Minister of the UAE, is the principal space agency of Dubai and has grown into one of the most active space institutions in the Arab world. MBRSC has overseen an ambitious portfolio of missions in the years since DubaiSat-1's launch, including subsequent Earth observation satellites and, most prominently, the Emirates Mars Mission — also known as Hope — which successfully entered Mars orbit in 2021. DubaiSat-1 stands near the beginning of that trajectory, representing the organization's first operational experience with a satellite in orbit.

The specific mass of DubaiSat-1 is not recorded in the catalog data available to this site. The satellite's manufacturer, as formally listed in tracking registries, is also not specified. Based on the orbital parameters and the general class of remote sensing spacecraft built by Satrec Initiative during this period, DubaiSat-1 is consistent with a small satellite platform, though precise mass and dimensions are not confirmed here.

Significance and Current Status

When DubaiSat-1 was launched in the summer of 2009, the UAE had no heritage of operating its own orbital assets. The satellite's successful deployment and operation marked the country's entry into the community of spacefaring nations — a distinction that carries both symbolic and practical weight. For a country of the UAE's size and age, reaching orbit with a domestically operated spacecraft within decades of national founding was a notable achievement, and DubaiSat-1 served as the proof-of-concept that underpinned subsequent investment in the space sector.

The satellite also holds significance within the broader context of emerging space nations in the Global South and the Middle East. During the 2000s, a growing number of countries — including several in Asia, Africa, and the Arab world — began pursuing small satellite programs as a means of accessing space-based capabilities without the enormous budgets historically required for large government space agencies. DubaiSat-1 was part of this wave, and its partnership model with an established foreign manufacturer became a template that other emerging space programs have followed.

As of the data available to this site, DubaiSat-1 remains in orbit. Whether the satellite is currently operational, in a reduced-service state, or simply maintaining orbit without active use is not confirmed in the catalog. Satellites at this altitude can remain aloft for extended periods even after their operational missions conclude, and the line between an active Earth observation satellite and a dormant but tracked object is not always publicly documented in official registries. What is certain is that DubaiSat-1 has been circling Earth for more than fifteen years since its launch, continuing to contribute to the orbital environment it joined in 2009.

How to Spot It

DubaiSat-1 orbits at an altitude of roughly 650 km in a sun-synchronous orbit inclined at 98.0°, which means its ground track carries it over most populated latitudes. Like most small to medium satellites in low Earth orbit, it is not ordinarily visible to the naked eye under typical conditions, but it may be detectable with binoculars or a small telescope during favorable passes — particularly during twilight hours when the satellite is sunlit against a darkened sky.

The best opportunities for visual observation occur within the first one to two hours after local sunset or before local sunrise, when the observer is in darkness but the satellite, still high above the horizon, remains illuminated by direct sunlight. At its orbital period of approximately 97.6 minutes, DubaiSat-1 makes multiple passes over most locations each day, though not every pass will be visible from a given site. Dedicated satellite tracking applications and websites — including this one — can calculate precise rise times, maximum elevation angles, and azimuth headings for any location using current TLE data derived from NORAD catalog entry 35682.
