Cost vs. Satellites

A satellite's coverage.
A drone's flexibility.

Solar-powered platforms that station-keep above weather, above commercial traffic, delivering persistent coverage where and when you need it.

📡

Connectivity

Broadband and 5G coverage for remote and underserved regions. One platform covers thousands of square kilometers with low-latency, direct-to-device connectivity.

👁

Persistent ISR

Months-long intelligence, surveillance, and reconnaissance. High-resolution imaging and real-time video from the stratosphere without orbital constraints.

🌍

Environmental Monitoring

Continuous atmospheric data collection, wildfire detection, maritime patrol, and climate observation with persistent, repositionable coverage.

Disaster Response

Rapid deployment to restore communications and provide real-time situational awareness when terrestrial infrastructure fails. Airborne within hours, not months.

One platform. Two missions.

Designed from the ground up for interchangeable civil and military payloads on the same airframe.

Civil Applications

  • Rural and maritime broadband coverage
  • Precision agriculture and crop monitoring
  • Wildfire detection and tracking
  • Climate and atmospheric research
  • Emergency communications relay

Defense Applications

  • Border and maritime surveillance
  • Signals intelligence and EW relay
  • Secure tactical communications
  • A2/AD capability bridging
  • Force protection and ISR overwatch
01

Cheaper than Satellites

No launch vehicle. No orbital slot. Solar-powered flight means near-zero fuel costs. Deploy, maintain, and recover from a simple ground site.

02

Faster than Infrastructure

Operational in hours, not years. No fiber trenching, no tower permitting, no satellite manufacturing queue. Coverage where you need it, when you need it.

03

Persistent as Orbit

Months of continuous station-keeping above 60,000 feet. Above weather, above traffic, with resolution and latency that satellites cannot match.

The stratosphere is the next frontier.
We're building the infrastructure for it.

StratoSentinel is positioning to become the operating system for stratospheric services. Persistent coverage, dual-use by design, deployed at a fraction of conventional costs.
