What is RTLS?
Return-To-Launch Site (RTLS) is a booster recovery technique where the first stage of the launch vehicle returns to its original launch pad for a vertical powered landing.
This method minimizes time between launches, eliminates complex ship recovery logistics, and significantly reduces cost per launch.
Key Capabilities
π― Precision Landing: GNSS + terrain-relative navigation for touchdown within 5-meter accuracy
π§ Autonomous Guidance: Onboard decision engine with wind, drift, and engine margin compensation
π₯ Retro-propulsion: Multi-burn profile with boostback, reentry, and landing burns
π Pad Integration: Shock-absorbing landing pads with thermal-resistant flame shields
β»οΈ Reuse Cycle: Designed for up to 15 flights with minimal refurbishment
Integrated Across Gatkul Vehicles
RTLS is embedded in the design of Vajra, Trishul, and PADMA-class launch vehicles. Each stage integrates gimbal-capable Ragam engines,
deployable landing legs, and heat-protected control surfaces to enable controlled return to the pad β even under high-mass or windy conditions.
Landing Sequence
Boostback Burn: Post-staging retrofire to reverse downrange momentum
Controlled Reentry: Grid fin stabilization + passive drag shaping
Landing Burn: Final descent with throttle ramp-down for soft vertical touch
Landing Pad Lock: Autonomous leg deployment and pad capture confirmation
Strategic Advantages
π Rapid booster turnaround (under 48 hours)
π Environmental benefit: No recovery ships, no ocean drop
π° Lower operating cost per kg to orbit
π‘ Ideal for orbital and suborbital missions from coastal pads
2026: Orbital-class RTLS from Trishul-1 core stage
2027: Multi-pad turnaround testing with PADMA boosters
Landing the Future
With RTLS, we're closing the loop on expendable launch. Every return is a beginning β
one that brings aerospace logistics closer to terrestrial efficiency. Gatkulβs precision RTLS systems unlock high-cadence launches
with minimal overhead, enabling space infrastructure at scale.
