(Very short) story time
It all really started with EISCAT_3D...
So what is
NOSTRA
- ESA Project: P3-SST-VIII EISCAT 3D Performance Analysis
- ESA Project: AO10111 EISCAT 3D Radar Processing Preliminary Design
Background: EISCAT
So what is
NOSTRA
- ESA Project: P3-SST-VIII EISCAT 3D Performance Analysis
- ESA Project: AO10111 EISCAT 3D Radar Processing Preliminary Design
- Tri-static high-power large-aperture phased-array capability...
is fantastic!

is fantastic! - Research instrument - not Space Traffic Management
- Not optimized for Space Surveillance and Tracking
- Global need for more and better data in heaps

NOSTRA
Soooooo could we just build a dedicated SST radar?
Background: EISCAT
NOSTRA
- Mono-static radar $\mapsto$ 5-15 seconds for orbit determination
- Tri-static radar $\mapsto$ 0.1 seconds for initial orbit determination
- Capacity increases by a factor of 50-150 with a factor of ~3 in cost
- Maintainable catalogue size is limited by radar time
- Fast enough to measure "all" objects within FoV
- Three transmitters $\mapsto$
system redundancy, higher accuracy, and mono-static operations for each site possible - Nordic location $\mapsto$ existing infrastructure, polar orbits, "science park"

Project S2-SD-04:
NOrdic multi-STatic space debris Radar Architecture
Finish in ~October 2025
- Research questions
- Long-term atmospheric drag characterization
- Debris shape characterization
- Effect of space weather events on space objects
- Fragmentation events
- Scheduling optimization
- Atmospheric effects of re-entry
- ...
Closing question:
what research do you think would be possible with such a system?
