S.L.N Technologies Private Limited (SLN) is a premier Electronic Systems Design and Manufacturing (ESDM) company, delivering high-reliability and ruggedized electronic solutions for the Aerospace and Defence sectors.
With over three decades of sustained contribution to India’s defence self-reliance, SLN has established itself as a trusted indigenous partner for mission-critical systems deployed across air, land, and naval platforms.
SLN offers complete lifecycle solutions spanning concept design, development, testing, qualification, manufacturing, integration, and long-term maintenance.
Our capabilities support both Build-to-Specification (BTS) and Build-to-Print (BTP) engagement models, enabling customers to accelerate programs while ensuring uncompromised reliability and compliance.
SLN specializes in advanced embedded and hardware-centric disciplines, including:
Our systems are engineered for harsh environments and long operational life, aligning with stringent aerospace qualification requirements.
S.L.N’s solutions address a wide spectrum of airborne, ground, and naval applications, including:
SLN has deep expertise in complex electronic interfaces such as Analog, Discrete, RS-232/422/485, Ethernet, USB, SPI, CCDL, MIL-STD-1553B, ARINC-429, ARINC-717, Audio, and Video.
We are proficient in industry-proven bus architectures including PCI, CompactPCI (cPCI), VME, VME64x, VPX, PXI, PMC, and Custom Bus Architectures.
Our development and qualification processes align with stringent aerospace standards:
SLN is an AS9100D certification. We are a CEMILAC-certified Design House for airworthy systems and a DSIR-recognized In-House R&D Unit under the Department of Scientific and Industrial Research, Government of India.
SLN is an approved and registered vendor to leading Indian defence organizations including HAL, BEL, ECIL, DRDO, and BDL.
SLN’s high-reliability embedded systems are operational in some of India’s most demanding programs. Key deployments include:
SLN continues to invest in indigenous technologies across:
S.L.N has successfully designed, developed, qualified, and flight-approved the SSFDR for Su-30 MKI, overing the complete journey from interface definition to certification. The system reliably samples aircraft sensors and cockpit voice data for post-flight analysis and crash investigation. This program established S.L.N as one of India’s leading indigenous manufacturers of Flight Data Recorders.
Building on this expertise, S.L.N developed the CVFDR for the Light Utility Helicopter (LUH)—a compact, low-power solution optimized for rotary-wing constraints. Today, S.L.N is capable of supplying CVFDR solutions for both fixed-wing and rotary-wing aircraft.
S.L.N’s deep understanding of embedded systems enables the design of robust, accurate, and scalable ATE solutions for systems, sub-systems, and electronic modules. Our ATE portfolio includes:
S.L.N is a leading indigenous developer of Antenna Control Systems for Radar and SATCOMapplications. We have developed and deployed seven variants of radar ACS,operating reliably across diverse environmental conditions. Our ACS solutions include:
S.L.N stands among India’s elite Electronic Systems Design and Manufacturing companies, delivering state-of-the-art indigenous solutions comparable with leading global OEMs. With continuous investment in engineering talent, infrastructure, and R&D, S.L.N remains committed to advancing high-reliability embedded systems for mission-critical aerospace and defence applications,strengthening India’s technological sovereignty.
