Silicon Valley startup Apolink, founded by 20-year-old Jammu native Onkar Singh Batra, is advancing plans to eliminate global satellite communication blackout periods using a low Earth orbit orbital relay constellation. Batra, who built an open-source satellite in high school and taught engineering concepts at IIT Jammu before founding Apolink in Palo Alto, secured $4.3 million in venture seed funding led by Y Combinator. The company’s initiative aims to maintain continuous data transmission for orbital assets without requiring proprietary hardware retrofits, addressing a persistent spatial telemetry gap that has historically delayed critical Earth-observation data.
PALO ALTO, Calif. — A California-based aerospace startup led by 20-year-old Jammu native Onkar Singh Batra is moving forward with orbital testing for a satellite communication network designed to resolve data blackouts in low Earth orbit.
Founded in Palo Alto in 2024, the company, Apolink—a name derived from “apogee” and “link”—is developing a 32-satellite constellation to act as orbital relay stations. The venture secured $4.3 million in seed funding in 2025 at a $45 million valuation from investors including Y Combinator. In July 2026, Apolink successfully deployed its first demonstration satellite into orbit aboard a SpaceX rideshare mission, marking a key milestone in efforts to establish continuous line-of-sight connectivity for commercial and governmental space assets.
Early Technical Milestones in Jammu
Batra’s path to Silicon Valley began in Jammu, India, where exposure to information technology through his father’s professional background sparked an early involvement in software development. At age 7, Batra launched his first website, earning recognition from Guinness World Records as the world’s youngest male webmaster. By age 12, he had authored a computer science book, and at 13, he launched an initial technology startup.
During the COVID-19 pandemic, the President of India awarded Batra the Rashtriya Bal Puraskar (National Child Award) for developing an interactive web platform designed to distribute emergency resources. By 2020, at age 14, Batra turned his focus toward space systems engineering.
While completing his 12th-grade studies in Jammu in 2022, the 16-year-old Batra led the development of InQube, a 1-kilogram satellite recognized as India’s first open-source satellite project. Designed with fully published schematics to allow educational institutions and independent developers to replicate the technology, InQube attracted regional academic interest. Before completing his secondary school education, Batra was invited to guest lecture on space systems engineering to undergraduate students at the Indian Institute of Technology (IIT) Jammu.
The Physics of Orbital Blackout Period
During the development and testing of InQube, Batra confronted a long-standing challenge in orbital mechanics: communication latency caused by terrestrial ground-station geometry.
Low Earth orbit (LEO) satellites typically operate at altitudes between 300 and 2,000 kilometers above the Earth’s surface, traveling at speeds near 7.8 kilometers per second. At these velocities, a single orbit takes roughly 90 to 120 minutes. Because ground stations have a limited line of sight due to the curvature of the Earth and geographic constraints, LEO satellites regularly spend up to 40 minutes per orbit out of contact with terrestrial receivers—a phenomenon known in space operations as a “dead zone.”
For operational earth-observation platforms monitoring real-time events—such as wildfires, oceanic flooding, or geopolitical developments—these coverage gaps delay critical data delivery to first responders and decision-makers on the ground.
Traditional approaches to mitigating these blackouts carry high technical or financial burdens:
- Ground Network Expansion: Constructing, licensing, and maintaining global terrestrial ground stations requires significant capital and faces diplomatic and geographic constraints, particularly across oceanic expanses.
- Geostationary Relays: Positioning relay satellites in higher geostationary orbits (roughly 35,786 kilometers above Earth) provides wide coverage, but conventionally requires customer satellites to carry heavy, specialized hardware and directional tracking antennas. Most legacy or lightweight small satellites lack the mass, power budget, or volume to accommodate these retrofits.
Silicon Valley Expansion and the Apolink Architecture
Seeking to resolve the hardware compatibility problem without requiring specialized retrofits on existing satellite fleets, Batra moved to the United States to launch Apolink in 2024.
The startup’s proposed solution centers on a ring constellation of 32 small satellites deployed in low Earth orbit. Each Apolink unit integrates dual optical (laser) and radio-frequency (RF) communication payloads. Acting as an orbital mesh network, the constellation intercepts signals from customer satellites operating in surrounding orbits and relays the data laterally from space asset to space asset until it reaches a node positioned over an available ground terminal.
By utilizing standard, non-proprietary RF frequencies alongside high-bandwidth laser links, the architecture allows legacy and newly deployed satellites to transmit data continuously without modifications to their original bus designs or antenna configurations.
Addressing investors and aerospace industry representatives during a technical briefing in California following the seed funding round, Batra outlined the practical focus of the initiative:
“The core limitation of low Earth orbit operations has never been data collection; it has been data transit,” Batra said, presenting the constellation schematics to an audience of venture partners. “When an earth-observation platform captures high-resolution imagery of an active disaster zone, that data loses value for every minute it sits in onboard storage waiting for a ground station pass. By building an open-protocol relay network in orbit, we make space data instantly accessible regardless of where the satellite happens to be floating at that moment.”
With the successful July 2026 launch of its inaugural test asset aboard a SpaceX falcon rocket, Apolink has commenced in-orbit validation of its payload systems, high-speed data cross-links, and compatibility protocols. The company plans to proceed with phased constellation deployments over the coming years as it seeks to build out a seamless global communications layer for the growing orbital economy.
