Page 4: Introduction
Figure 1 represents how NEO-D9S and ZED-F9 work together: Figure 1: NEO-D9S and ZED-F9 scenario NEO-D9S is a satellite data receiver for L-band correction broadcasts, which can be configured to work with a variety of correction services. This document provides instructions on how to configure NEO-D9S for this purpose and provides configuration examples for the PointPerfect service, SPARTN L-band correction, and ZED-F9 receivers. - Page 5 For more details, see the u-center user guide [3]. The easiest way to test how to configure the NEO-D9S and ZED-F9 receivers is to make use of the C099-F9P and C101-D9S application boards. See the related user guides [6] and [7], and in particular Chapter 4 of the C101-D9S User Guide.
