Global Phased-Array
RADAR NETWORK
A unique, commercial data source from LeoLabs. Each radar is built in less than one year.

LeoLabs’ radars track satellites and debris around the clock.
- They are unaffected by sunlight, clouds, rain, snow, and wind.
- Each radar tracks thousands of objects per hour — they use phased-array technology to switch from one object to the next every millisecond
- The Kiwi Space Radar (KSR), and future radars, track debris as small as 2 centimeters using S-band electronics
- The first two radars use UHF electronics that have been in operation for over 10 years
LeoLabs is building a network of 6+ radars.
This network will:
- Cover the Southern Hemisphere
- Cover the Equator (low inclination orbits)
- Cover the Northern Hemisphere
- Revisit satellites many times per day
- Protect satellites from small debris
- Track newly launched satellites within hours of deployment
LeoLabs has 3 radars in operation today.

PFISR

MSR
The Midland Space Radar, located near The City of Midland, Texas. LeoLabs’ first demonstration of a one dimensional phased-array radar for space. A UHF radar covering mid-inclination orbits, including the International Space Station (ISS). Operating since 2017.

KSR
The Kiwi Space Radar, located in New Zealand. LeoLabs’ first S-band radar, making it the first to detect small debris. It covers the Southern Hemisphere and mid-inclination orbits. Operating since 2019.

See the data from these radars in action. Building a tracking service used to mean building radars, building software, and staffing. This took decades and billions of dollars. LeoLabs handles all of that. Tracking services are now available in real-time, over the internet, from a network of proven radars.
