Global Navigation Satellite System Software Defined Radio

Abstract

There are two major trends that are driving the nature of GNSS receiver development today. First, there is a growing numberofGlobalNavigationSatelliteSystems(GNSS) thatexistorareunderdevelopment,sothat inthenearfuture, users will potentially have access to many more satellites and systems than they do today. The second major trend is the growth in computing power and flexible signal processing capability. These two factors, combined together, point to the value of having a software-defined radio that is able to acquire and track as many GNSS signals, from various systems, as possible. This research describes the development of a GNSS software receiver at the Advanced Navigation Technology (ANT)Center at AFIT. This software receiver uses data collected by a high-quality receiver front end developed by Ohio University, which has a 24 MHz bandwidth and a 12-bit sampler operating at 57M samples per second. The ANT Center Software Receiver currently runs in a post-processing mode, and is able to simultaneously acquire and track signals from multiple GNSS systems.
