KAZSAT-2

KazSat-2 is a Kazakhstani geostationary communications satellite operated by JSC KazSat, the state satellite operator of Kazakhstan. Carrying the NORAD catalog identifier 37749 and the international designator 2011-035B, it was constructed under a collaborative arrangement between two established space manufacturers and launched into a high geostationary orbit in July 2011. The spacecraft represents Kazakhstan's continued effort to build an independent national satellite communications infrastructure, following the earlier, troubled KazSat-1 mission. As of the time of writing, KazSat-2 remains in orbit, stationed in the geostationary belt above the equator.

Mission and Purpose

KazSat-2 was developed to provide communications services over the territory of Kazakhstan and neighboring regions. The satellite is the second in Kazakhstan's KazSat national satellite series, a program intended to give the country sovereign control over key satellite communications capacity and reduce dependence on foreign orbital slots and transponder leases.

The context of KazSat-2's development is important. Its predecessor, KazSat-1, suffered significant operational problems following its launch and ultimately could not fulfill its intended service life, leaving Kazakhstan without a functioning national communications satellite for a period. KazSat-2 was therefore a high-priority replacement and continuation of the national program, designed to restore and expand domestic satellite communications capability.

The specific operational details of KazSat-2's payload configuration — including the number and type of transponders, frequency bands employed, and the exact geographic coverage footprint — are not recorded in publicly available tracking catalogs. What is publicly established is that the satellite was built to serve telecommunications functions consistent with a national communications infrastructure satellite, potentially including services such as television broadcasting, internet connectivity, and government communications. The mission type is not formally cataloged in available data.

Orbit and Tracking

KazSat-2 occupies a geostationary orbit, one of the most strategically valuable orbital regimes available to satellite operators. In a geostationary orbit, a satellite circles Earth at an altitude where its orbital period precisely matches the planet's rotation period, causing the satellite to appear effectively stationary above a fixed point on the equator as seen from the ground. This characteristic makes geostationary satellites ideal for communications applications, as ground-based antennas can be aimed at a fixed point in the sky without the need for tracking mechanisms.

The orbital parameters cataloged for KazSat-2 confirm a near-perfect geostationary configuration. The satellite has an apogee of 35,798 km and a perigee of 35,791 km, giving it an extremely circular orbit with negligible eccentricity. The orbital inclination is recorded at 0.0°, meaning the satellite's orbital plane is aligned precisely with Earth's equatorial plane — exactly as required for a true geostationary orbit. The orbital period is 1,436.1 minutes, which corresponds closely to one sidereal day, the fundamental requirement for maintaining a stationary position relative to Earth's surface.

These parameters collectively indicate that KazSat-2 is operating in a tightly controlled station-kept orbit, as is standard for active commercial geostationary satellites. Operators routinely perform small thruster burns to counteract gravitational perturbations from the Moon and Sun, as well as solar radiation pressure, all of which would otherwise gradually alter the satellite's position over time.

Because KazSat-2 resides at approximately 35,800 km altitude, it is not a practical target for casual visual observation. Geostationary satellites do not move against the star field and appear only as faint, stationary points of light even under ideal conditions and with optical aid. Tracking the satellite in the conventional sense used for low Earth orbit objects is not applicable; instead, its position is monitored through radio frequency methods and periodically updated in orbital element sets.

Design and Operator

KazSat-2 was manufactured through a division of labor between two contractors. The satellite bus — the structural and engineering core of the spacecraft, housing the propulsion system, power systems, attitude control, and onboard computing — was built by the Khrunichev State Research and Production Space Center, a major Russian aerospace enterprise with extensive experience in launch vehicles and spacecraft. Khrunichev is perhaps best known internationally as the manufacturer of the Proton rocket series and as a contributor to the International Space Station.

The communications payload — the mission-specific equipment responsible for receiving, amplifying, and retransmitting signals — was designed and supplied by Thales Alenia Space, a Franco-Italian aerospace company with a substantial portfolio of commercial and governmental communications satellites. Thales Alenia Space's involvement spans the full KazSat series; the company also provided the payloads for both KazSat-1 and the later KazSat-3, giving the Kazakh national program a degree of technological continuity across its satellite generations.

KazSat-2 has a recorded mass of 1,330 kg. This places it in the medium-mass category for geostationary communications satellites, consistent with a satellite designed for regional rather than global coverage.

The satellite was launched on July 14, 2011, by a Proton-M launch vehicle with a Briz-M upper stage — the same Russian launch system that has lofted many geostationary communications satellites for international customers. The Proton-M/Briz-M combination is a well-established flight configuration routinely used to deliver payloads to geostationary transfer orbit, from which the Briz-M then raises the spacecraft to its final geostationary position. It should be noted that the Wikipedia-derived background for this satellite records the launch time as 23:16:10 UTC on July 16, 2011, while the verified catalog data lists the launch date as July 14, 2011; minor discrepancies of this nature sometimes arise between tracking databases and other sources due to differences in how pre-launch, liftoff, and orbital insertion events are recorded.

The satellite is operated by JSC KazSat, the Kazakhstani state-owned entity responsible for managing the country's national satellite assets. JSC KazSat operates under the broader framework of Kazakhstan's space policy, which has sought to establish the country as a capable spacefaring nation with control over its own orbital infrastructure.

Significance and Current Status

KazSat-2 holds a meaningful place in Kazakhstan's space history. When KazSat-1 encountered severe technical difficulties that curtailed its operational usefulness, the national satellite program faced a significant setback. The successful development and deployment of KazSat-2 represented a recovery and a validation of Kazakhstan's commitment to maintaining a sovereign satellite communications capability — one that is strategically important for a large, landlocked country where terrestrial communications infrastructure is unevenly distributed across vast distances.

By establishing a functioning national satellite, Kazakhstan gains control over its own orbital slot in the geostationary arc, an internationally allocated resource governed by the International Telecommunication Union. Holding and actively using such a slot has geopolitical and economic dimensions beyond mere communications capacity.

KazSat-2 was followed in the series by KazSat-3, which extended the national program's coverage and capacity. The KazSat series as a whole demonstrates Kazakhstan's broader ambitions in the space sector, which include the Baikonur Cosmodrome — the world's first and historically one of the busiest orbital launch facilities — located on Kazakhstani territory and operated under a long-standing arrangement with Russia.

As of the current catalog data, KazSat-2 remains in orbit with no reentry or decay date recorded. The satellite's mission status is not publicly detailed in available tracking databases. For an active geostationary communications satellite of its age and design, continued station-keeping operations and payload service would be the expected operational profile, though this cannot be confirmed from orbital tracking data alone. Whether the satellite remains in active commercial service, has been placed in a graveyard orbit, or is in some intermediate operational state is not established by the information available in the tracking record. Observers and users seeking current operational status would need to consult JSC KazSat or official Kazakhstani telecommunications authorities for authoritative confirmation.

KazSat-2 thus stands as a documented artifact of Kazakhstan's early twenty-first century effort to build independent space capabilities — a program that, despite early difficulties with its first satellite, established a functioning series of national communications spacecraft serving one of Central Asia's largest and most resource-rich nations.
