What Constelli does
Constelli (legally Constelli Signals Private Limited) is a Hyderabad, India-based defense electronics and signal processing company founded in 2017 by Satya Gopal Panigrahi (CEO) and Avinash Chenreddy (CTO). The company designs and manufactures hardware and software for Electronic Warfare, Radar, and Communications applications serving India's Ministry of Defence, DRDO, and select international defense contractors. Its product portfolio centers on India's first IRIG-106 standard digital telemetry receiver (covering PCM/FM, SOQPSK-TG, BPSK, QPSK at 10 Mbps), a DRFM-based Compact Radar Target Echo Simulator (CRTS 2816) covering L through Ka frequency bands, the CEWS-G electronic warfare emitter simulation suite, and the Constelli Radar Toolkit (CRTK) — a LabVIEW add-on that extends NI's RF and FPGA platforms (VST, USRP, VSG, VSA) with radar waveform generation and analysis frameworks. Supporting products include a Compact Telemetry Station, Digital Telemetry Transmitter, Drone-Based Telemetry Receiver Payload, and the free PINGALA Calculator mobile app for RF/Microwave/DSP/Radar field calculations.
The company's underlying technology stack combines proprietary DRFM algorithms, FPGA firmware, and RF/microwave hardware design with tight integration into the NI/Emerson LabVIEW ecosystem. Constelli generates revenue through three streams: (1) hardware sales of EW systems, radar target simulators, and telemetry receivers/transmitters to defense ministries, DRDO, and defense contractors; (2) software licensing of CRTK and other software products with development and deployment license tiers; and (3) custom engineering services for aerospace and defense system development, testing, and validation. Pricing is not publicly disclosed; sales follow the standard defense procurement model of quote-based direct engagement with technical and procurement decision-makers, supplemented by conference participation (ADECS, ICORT, IEEE Radar Conference, MAPCON, NI events). Geographic reach spans India (primary) and export markets in South Korea, Australia, Singapore, and Turkey. The company has raised $23 million cumulatively — $3M pre-Series A from Pravega Ventures (January 2025) and $20M Series A led by General Catalyst (February 2026) with 360 One Asset Management also participating.

Constelli product offering
Product offeringCore offering
Constelli designs, develops, and sells defense and aerospace electronics across three domains: Electronic Warfare, Radar, and Communications. The product portfolio includes digital telemetry receivers and transmitters (including India's first IRIG-standard digital telemetry receiver), DRFM-based radar target echo simulators, drone-based telemetry payloads, and the Constelli Radar Toolkit for LabVIEW software. The company also delivers electronic warfare signal generation and testing suites, with end-to-end capabilities spanning hardware and in-house developed software.
Product overview
Constelli delivers a comprehensive portfolio of defense and aerospace electronics solutions organized across three core domains: Electronic Warfare, Radar, and Communications. The product lineup centers on telemetry systems (Digital Telemetry Receiver, Compact Telemetry Station, Digital Telemetry Transmitter, and Drone-based Telemetry Receiver Payload) and radar solutions (Radar Target Echo Simulator). Supporting these are software tools including the Constelli Radar Toolkit for LabVIEW (CRTK) for radar development and CEWS-G for electronic warfare testing and validation. The Pingala Calculator app provides a complementary field tool for engineers. All products are designed for seamless integration, real-time performance, and operational flexibility across defense testing and airborne ISR missions.

Constelli competitors and assessment
Company assessmentBroad incumbents
- L3Harris Technologies: Large US defence prime with deep portfolios in electronic warfare, RF/microwave, tactical communications and avionics. Directly comparable technology base to Constelli's EW, radar and telemetry products, though serving a much broader global customer set across many more platforms.
- Bharat Electronics Limited (BEL): Indian public-sector defence electronics PSU supplying radar, EW, communications, and telemetry systems to the Indian MoD and DRDO. Directly comparable in target customer (same Indian defence buyers) and many product lines (radar, EW, communications), with much larger scale.
- RTX (Collins Aerospace / Raytheon): Global defence prime with major EW, radar, and tactical communications franchises. Comparable product categories (EW processors, radar, datalinks) but operates at vastly larger scale and across broader platforms than Constelli.
- Northrop Grumman: US prime with leading electronic warfare, radar and integrated air/missile defence portfolios. Competes with Constelli in adjacent capability areas (EW, SIGINT, radar signal processing) but as part of a much broader systems portfolio.
Direct peers
- Mercury Systems: US-based defence electronics company specialising in RF, microwave, signal processing and mission-critical subsystems for EW, radar and intelligence applications. Closest peer in terms of product/solution mix (DRFM, radar processing, EW subsystems) and customer type (defence primes and government).
- Data Patterns (India): Indian defence and aerospace electronics company designing and building radar, EW, communications and avionics subsystems for Indian defence programmes. Closely comparable in size, product scope (radar/EW/comms), and customer base (DRDO, MoD, Indian primes).
- Astra Microwave Products: Indian-listed company developing RF/microwave components, subsystems and modules for radar, EW, telemetry and space applications. Comparable technology base (RF/microwave, DRFM-adjacent subsystems) and customer overlap with DRDO, ISRO and defence primes.
- Centum Electronics: Indian defence and aerospace electronics company supplying RF/microwave modules, embedded systems, and electronic warfare subsystems to global defence customers including Indian and US primes. Closely comparable product categories (EW, radar, telemetry/communications modules).
- Saankhya Labs: Indian wireless communications and signal processing company with defence product lines in software-defined radio, satellite communications and electronic warfare. Comparable as a domestic Indian peer building indigenous signal-processing hardware/software for defence.
Others
- Keysight Technologies: Test and measurement equipment vendor whose RF/vector signal analysis platforms are used in radar and EW development workflows alongside NI's instruments that Constelli's CRTK integrates with. Comparable as an ecosystem participant in defence RF test and validation, not a direct competitor.
