GÖKTÜRK-3 SAR Satellite Programme

Current status

GÖKTÜRK-3 is Türkiye’s programme to acquire its first satellite system carrying a Synthetic Aperture Radar (SAR) payload. SSB states that the development contract was signed in 2024 between SSB and Turkish Aerospace.

Unlike electro-optical observation satellites, SAR can provide imaging in darkness and through many weather conditions. SSB therefore frames GÖKTÜRK-3 as a major expansion of the Turkish Armed Forces’ space-based imaging and intelligence capability, while also identifying civilian uses in disaster management, agriculture, maritime monitoring, cartography, geodesy and geology.

The key editorial point is that GÖKTÜRK-3 should currently be described as a development programme, not an operational satellite. ASELSAN’s 2025 reporting states that the programme’s Mission Definition Review and System Requirements Review were completed during 2025. This indicates progress through programme-definition and requirements milestones after the 2024 contract, but it does not establish launch readiness.

Turkish Aerospace has published design information for GÖKTÜRK-3 in its space-systems material, including a sun-synchronous-orbit concept and multiple SAR imaging modes. Those figures may evolve as system design matures and should therefore be presented as published design data rather than fixed operational performance until programme authorities confirm the final baseline.

Why it matters

GÖKTÜRK-3 closes a major sensing gap between optical reconnaissance and all-weather radar imaging.

For military users, a national SAR satellite can improve persistence against cloud cover, darkness and environmental conditions that constrain electro-optical sensors. It also broadens the type of information that can be extracted from space-based surveillance, including maritime activity, terrain and change detection.

The programme also matters industrially because the value lies in more than the spacecraft. SAR payload technology, signal processing, ground stations, mission planning, data exploitation and secure dissemination all contribute to sovereign space-based ISR.

GÖKTÜRK-3 should therefore be tracked as an integrated space-and-intelligence system, not merely as a future launch.

What we track

System reviews and design maturity

Track preliminary and critical design reviews, payload qualification, spacecraft integration and environmental testing.

SAR payload

Follow frequency band, resolution, imaging modes, swath, revisit performance and domestic contribution only when the final programme baseline is publicly confirmed.

Ground segment and exploitation

A reconnaissance satellite’s operational value depends on tasking, receiving, processing, exploitation and dissemination. Track fixed/mobile ground segment and integration with national intelligence architecture.

Launch schedule

Do not publish an inherited or speculative launch date as current. Use only the latest SSB, Turkish Aerospace or other responsible government source.

Space heritage and domestic subsystems

Track which subsystems are derived from İMECE, GÖKTÜRK and TÜRKSAT 6A experience and which are new to the SAR mission.

Follow-on constellation potential

Monitor whether GÖKTÜRK-3 remains a single-satellite system or becomes part of a broader radar-imaging constellation or replacement architecture.
