On 25 April 2026, a Long March 6 (CZ-6) rocket launched the PRSC-EO3 – Pakistan’s third and final electro-optical remote sensing satellite – from the Taiyuan Satellite Launch Center in China’s Shanxi province. The PRSC-EO3 satellite entered its planned sun-synchronous orbit, marking the 640th mission of China’s Long March rocket series.
The PRSC-EO3 was developed by the Space and Upper Atmosphere Research Commission (SUPARCO), Pakistan’s national space agency, as the final satellite in the Pakistan Remote Sensing Satellite Electro-Optical System (PRSC-EOS) program. According to SUPARCO, the PRSC-EO3 will support disaster management, environmental protection, agricultural assessment, and natural resource surveying.
Pakistan’s President Asif Ali Zardari described the Pakistan satellite launch as a “historic milestone” and cited it as evidence of the country’s growing technical expertise. SUPARCO officials have also framed the PRSC-EO3 as an example of Pakistan’s pursuit of self-reliance in satellite design and production.
PRSC-EO3 Specifications: What May Differentiate It From SUPARCO’s Earlier Satellites
SUPARCO has not released detailed technical specifications for any of the three PRSC-EO satellites. However, the available reporting offers some basis for inference.
The PRSC-EO1, launched in January 2025, was described as Pakistan’s first indigenously built electro-optical imaging satellite. Its predecessor – the Chinese-supplied PRSS-1 – captured multi-spectral images at a resolution of roughly 3 m.
The PRSC-EO1 likely represented a step forward, potentially achieving sub-1 m resolution in its panchromatic band if SUPARCO drew on the specifications of the planned PRSS-O2 that was originally in the pipeline before the PRSC series replaced it. According to a SUPARCO official, the PRSC-EO1 has a designed lifespan of five years.
The PRSC-EO2, launched from a sea-based platform via China’s Smart Dragon-3 (SD-3) solid-fuel rocket in February 2026, carried a high-resolution EO payload. Quwa had previously noted that it was unclear whether SUPARCO planned a dedicated third EO satellite or whether the HS-1 had absorbed that role. The arrival of the PRSC-EO3 confirms that SUPARCO proceeded with a full three-unit EO constellation as originally planned.
The PRSC-EO3 appears to carry a more advanced payload suite than its predecessors. According to official descriptions cited by multiple outlets, the PRSC-EO3 satellite includes three experimental systems: a Multi-Geometry Imaging Module, an advanced energy storage system, and an onboard artificial intelligence (AI)-powered data processing unit.
The AI-powered processing unit is described as enabling “real-time analysis and intelligent decision support.” This is the first time any PRSC satellite has been reported to carry an onboard AI capability. In practical terms, this suggests the PRSC-EO3 can perform at least some image processing or anomaly detection onboard – filtering or prioritizing data before downlinking it – rather than transmitting all raw imagery to ground stations for post-processing.
This is a noteworthy development. As Quwa has previously noted, the gap in Pakistan’s space-based imaging capability has not solely been about hardware in orbit, but about the software and processing pipelines that convert raw imagery into actionable outcomes. An onboard AI processor represents a step towards closing that gap at the satellite level itself.
The PRSC-EO3’s Multi-Geometry Imaging Module, meanwhile, suggests a capability to capture images from multiple viewing angles or geometries in a single pass. This technique can enable stereo or tri-stereo imaging for 3D terrain modelling and elevation mapping.
Given that the PRSC-EO3 reportedly exceeds 500 kg – making it Pakistan’s largest domestically developed satellite – it likely incorporates a more substantial payload suite than its predecessors.
One can assume that each successive SUPARCO satellite has incorporated incremental improvements in resolution, data handling, or onboard processing, consistent with SUPARCO’s stated goal of building indigenous design capabilities through iterative development.
That said, in the absence of confirmed specifications from SUPARCO, the precise resolution, swath width, and spectral band configuration of the PRSC-EO3 remain uncertain.
