Adding Value … And Pushing it To the Right

Eating Your Own Dogfood

As a microsat company with a multi-faceted mission competing against larger, more narrowly-focused platforms, we require analytic capabilities to ensure our data has the fidelity required to make a difference....

… Fortunately, we are our own analytics company.

AIS: TOA and FOA Estimation

If we can derive a noise-free version of our received signal, then we can bring error sigmas down by a factor of root 2.

But that’s a big if
