I'm the Head of Analytics and Operations at OneSky Systems Inc., where I lead the design and development of our analytical services. I'm also a GNSS subject matter expert, specializing in the fields of GPS navigation accuracy and risk assessment.
I'm currently working on methods to quantify risk for UAV pilots and operators.
The analytical services documentation is located here. If you'd like to try them out, contact me - I can get you a demo API key..
This application lets you use a few of the GPS services I've made available.
This application allows you to analyze comm link budgets for any given set of transmitters, against a receiver moving along any route.
The service that this application is built on has more capabilities than this - you can also add jammers or other emitters to see their effect on your receiver.
