Space Domain Awareness
We cover Low Earth Orbit (LEO) between approximately 300 kilometers and 2,000 kilometers in altitude. Our radars cover inclinations between 30° and 150° today (and all inclinations in the next couple of years).
Today our radars track objects that are 10 centimeters across and larger. The Kiwi Space Radar (KSR), located in New Zealand, can detect smaller objects and data on those objects will be available to subscribers in the future.
As of early 2020, there are about 14,000 objects in LEO that are 10 centimeters across and larger. We are tracking those today. Approximately 1,700 of these are functional satellites. The rest are dead satellites, rocket bodies, and other debris.
Tracking satellites in LEO is difficult. LEO satellites move quickly so you cannot simply stare at a satellite with a single sensor for hours on end (like you can with GEO satellites). A satellite in LEO completes a full lap around the Earth every 90 minutes. It’s important to measure a satellite’s position and heading frequently because a satellite’s orbit can change due to variations in the atmosphere and due to intentional maneuvers. Frequent measurements can only be made with a network of sensors. With 3 radars in our network, a satellite passes over our radars up to 6 times per day.
No, we use radars because they can operate through rain, snow, wind, clouds, and daylight. We run them around the clock.
We used phased-array technology so our radars can switch from one object to the next every millisecond. At any given moment each radar is switching between multiple objects.
Our system is regularly tracking all the satellites in our catalog so we may have already scheduled the measurements you need. Subscribers can check the radar schedules multiple days in advance. We also offer a prioritization service so you can get many radar passes per day on the satellites you care about. Contact us for details about tasking and searching services.
Yes, a subscription gets you access to real-time data flowing from our network of proven radars. The subscription price covers everything you need. Separate charges for radar construction, radar operations and maintenance, software development, Information Technology (IT) operations, and the like, are relics of the past.
Yes, we run a fully automated Tasking, Collection, Processing, Exploitation, and Dissemination (TCPED) pipeline. Subscribers can access the data at the points in the pipeline that make sense for their applications.
You can access our online dashboards today. By subscribing to a dashboard seat license you can see dynamically generated content that shows detailed reports of the latest events in LEO. These dashboards also permit access to our archived data.
With our API you can easily route our data feeds into your software system. Our Field Applications Engineers stand ready to assist you. Plus, our API documentation is freely available online at https://platform.leolabs.space/documentation/api_quickstart.
No data should be trusted blindly. At LeoLabs, we believe in building trust through transparency. We report critical quality metrics, metadata, and operational status – the things you need to build the trust required to use our services operationally. This includes radar biases and residuals, state vector covariances, scheduled radar maintenance windows, the schedule for future measurements, and an archive of the schedule for past measurements. Our satellite operator customers compare our measurements and states to the state vectors they derive from their on-board GPS units. Multiple third-parties have evaluated our data with very positive results.
