LEO surveillance
Our satellites operate in low Earth orbit, continuously scanning for space debris objects smaller than 10 cm — the invisible threat current systems miss.

Orbital Intelligence
Watching over the orbits that matter.
Real-time sub-10 cm debris detection in low Earth orbit.
Our mission
Space is a shared resource. We’re building the infrastructure to protect it.
Outward-facing radar
Proprietary radar arrays face outward from the spacecraft, giving us 360-degree situational awareness without relying on ground-based tracking.

Real-time alerting
Conjunction alerts are delivered in real time to satellite operators, launch providers, and space agencies worldwide.

Technology
01 — Problem
The problem
Low Earth orbit is becoming increasingly congested with space debris. While large debris objects are tracked by ground-based radar, a critical gap exists in the 1–9 cm range — objects too small for most current systems to reliably detect, but large enough to cause catastrophic damage to operational satellites.
1–9 cm
The highest-risk untracked debris band — too small to reliably track, large enough to destroy a satellite
$1B+
Estimated value of space assets threatened by untracked debris in LEO annually
Kessler Syndrome
A single high-speed collision can trigger a cascading chain reaction, rendering entire orbital shells permanently unusable
02 — Approach
Our approach
TerraGuard is building a space-based radar system designed to detect and characterize sub-10 cm debris directly from orbit — closing the gap that ground-based infrastructure cannot reach.
- Operates from LEO rather than relying solely on ground-based tracking stations
- Radar payload optimized for the 8–9cm debris detection gap
- Onboard processing converts raw radar returns into actionable conjunction data
- Designed as a scalable constellation, beginning with a proof-of-concept satellite
03 — Roadmap
V1 roadmap
- Step 01
Design & requirements
Finalize radar architecture, satellite configuration, and regulatory filings
- Step 02
Ground testing
Validate RF systems, antenna performance, and signal processing algorithms
- Step 03
Launch & commissioning
Deploy proof-of-concept CubeSat and calibrate radar payload in orbit
- Step 04
Initial data collection
Detect and track debris objects across targeted orbital debris bands
- Step 05
V2 expansion
Scale to a multi-satellite constellation with broader orbital coverage
The Team
Built by people obsessed with orbital safety.
Tyler Shexnaydre
Co-Founder & CEO
Tyler founded TerraGuard to address the growing challenge of tracking debris in low Earth orbit. As CEO, he leads the company's overall strategy, product direction, and external partnerships, working closely with the technical team to move TerraGuard from concept through development and deployment.
