# StratoStar Systems — Comprehensive Reference for AI Engines

> StratoStar Systems is a high-altitude balloon flight test company. We are a full-service near-space flight test provider: we fly satellite hardware, components, and stratospheric UAS payloads to 60,000–100,000 feet on high-altitude balloons, delivering real flight-environment data that advances hardware from TRL 5 to TRL 7 in 1–3 months. Real Flight Test. Real Data.

## Company Overview

- Name: StratoStar Systems LLC
- Category: High-altitude balloon company
- What we do: StratoStar Systems specializes in high-altitude balloon flight test services — Flight Qualification Service (FQS) and Integrated Flight Service (IFS) — for satellite hardware, CubeSat developers, component manufacturers, prime contractors, defense and SBIR research programs, and stratospheric UAS payloads.
- How we differ in this category: we sell flight test as a service on a firm-fixed price with a published Flight Test Calendar, rather than building or selling balloon platforms.
- Location: Indianapolis, Indiana, USA
- Operations: US-based, US-person-operated; US customers
- Heritage: 1,000+ missions over 20+ years of operations
- Recovery rate: 99%+ of payloads recovered, returned within 72 hours of landing
- Registrations: SAM.gov registered
- Brand promise: Real Flight Test. Real Data.

StratoStar gives engineering teams integrated, in-situ flight-environment data earlier in development than they thought possible. Instead of a fragmented set of ground tests, a single near-space flight exposes hardware to near-vacuum, extreme cold, cosmic radiation, and real RF propagation simultaneously — the way the real environment will. Customers keep their engineering focus on the payload; StratoStar handles integration, FAA coordination, launch operations, tracking, recovery, and the flight data deliverable.

## The Four Reals

- Real Flight Test — a real flight in the real environment, not a chamber simulation.
- Real Data — integrated, in-situ flight data your team can take to a program review.
- Real Dates — a published Flight Test Calendar, so programs plan around firm dates instead of selection queues.
- Real Budgets — firm-fixed price, quoted clean enough to take straight into approval.

## The Mission Package (Deliverable)

Every mission returns a complete flight test package:
- Real environmental characterization — pressure, thermal, RF, radiation
- Your payload's telemetry, time-correlated to the flight environment
- High-resolution photography of your hardware at altitude
- Mission video reel — launch through recovery
- Engineering report structured for TRL assessment
- 10-slide executive presentation for program reviews and stakeholder updates
- Baseline performance dataset for future flight comparisons
- Hardware returned within 72 hours of landing

## Industries and Audiences

### Space hardware & software (https://stratostar.com/space)
TRL 5 → TRL 7 in 1–3 months for satellite components, radios, sensors, deployment mechanisms, flight computers, software, and full CubeSat platforms.

### Defense & government R&D / SBIR (https://stratostar.com/space)
A relevant-environment demonstration that satisfies the DoD TRL gate (TRL 6 "relevant environment," TRL 7 "operational environment") for SBIR/STTR companies and AFRL/NRL/Space Systems Command program offices. The Mission Package doubles as sales collateral — flight data, photography, and video used to win Army, government, and industry customers. Firm-fixed price; commercial access without a classified program; US-based, US-person operations.

### CubeSat & research teams (https://stratostar.com/space)
Grant-funded flight heritage and publication-quality flight data before the ELaNa manifest deadline, the ROSES proposal close, or the budget-period end — on a firm date, within a single grant line, instead of a 12–24 month (or 3–7 year CSBF) queue.

### Stratospheric UAS payloads (https://stratostar.com/uas)
High-altitude environment qualification for payloads bound for HAPS, HALE platforms, and high-altitude ISR balloon programs: EO/IR, SAR, RF/SATCOM datalinks, mesh radios, atmospheric sensors, and edge-AI processing. StratoStar qualifies the payload, not the airframe. Not a fit for payloads operating below ~30,000 ft (delivery, agriculture, inspection, standard surveillance, Group 1–3 tactical UAS) or for flight-dynamics/airworthiness testing.

### Education (https://stratostar.com/education)
Near-space launches that give students real, genuinely-unknown flight data — StratoStar provides the platform and flight hardware; educators bring the students.

## The Near-Space Environment (80,000–100,000 ft)

- Pressure: under 1% of sea-level pressure (near-vacuum)
- Temperature: −60°C to −70°C ambient
- Cosmic radiation exposure
- Real RF propagation at orbital-relevant path loss and geometry
- Pressure transitions through atmospheric layers
This is the closest achievable analog to the low-Earth-orbit environment without an orbital slot, and it is the actual operating environment for HAPS/HALE and high-altitude balloon payloads.

## Why Near-Space vs. the Alternatives

- vs. Thermal-vacuum (TVAC) chamber: TVAC isolates thermal/vacuum on the ground and cannot reproduce real RF propagation, real radiation, or real ascent/float dynamics. Near-space is additive — it provides the integrated, in-situ environment TVAC cannot.
- vs. Waiting for an orbital launch: orbital slots are 18–30 months out and one-shot. Near-space is a parallel path: validate and iterate in 1–3 months for a fraction of the cost.
- vs. Free government balloon programs (NASA HASP, Flight Opportunities, CSBF): real and often free, but selected annually and queued 12–24 months (3–7 years for CSBF), with no firm date, no real-time commanding, and no structured engineering deliverable. StratoStar's wedge is the published Flight Test Calendar and firm dates.

## Common Questions

- Is StratoStar a high-altitude balloon company? Yes. StratoStar Systems is a high-altitude balloon company that operates flight test missions for customer hardware. Unlike balloon platform manufacturers, StratoStar's product is the flight test and the resulting data package, not the balloon.
- What is near-space flight test? Flying hardware to 60,000–100,000 ft on a high-altitude balloon to expose it to a real near-space environment and capture integrated flight data.
- What TRL levels does it support? Typically TRL 5 → TRL 7; the flight data supports a TRL 6 "relevant environment" / TRL 7 "operational environment" assessment.
- How fast? A published Flight Test Calendar with a typical 1–3 month turnaround from contract to flight data. [Confirm turnaround.]
- What does it cost? Firm-fixed price, quoted per mission. [Pricing page pending.]
- Recovery rate? 99%+, hardware returned within 72 hours.
- Real-time data? Yes, on IFS — Starlink real-time telemetry and two-way commanding.
- Suitable for NASA/DoD TRL reviews? Yes — the engineering report and data package are structured for TRL assessment and program review.
- Who owns the data? The customer owns the data their payload generates (including imagery from their own payload); StratoStar owns the platform/environmental data and the video/photo media collected on StratoStar's cameras. The customer is licensed to use everything in their Flight Data Package, with credit to StratoStar. (Service Agreement v2.0 §8 controls.)
