Interferometry Techniques

Abstract

Most of today’s receivers use the pseudorandom C/A- and P-code pulse sequences broadcast by the GPS satellites to obtain their current positioning solutions. But a more sophisticated technique called interferometry derives information for its navigation solutions from the sinusoidal carrier waves coming down from the satellites. Interferometry solutions, which are also called carrier-aided solutions, are more difficult to obtain, but, in situations where they are valid, they can provide surprisingly large reductions in the navigation errors, especially for static and low-dynamic surveying applications. Some airborne and spaceborne applications can also benefit from carrier-aided processing techniques.
