To Understand the Receiver Status Screen Data
One of the key indicators on the screen is the ACQUISITION
status indicator. It shows “ GPS 1 PPS Valid ” as soon as satellite
information is sufficient.
Refer to Chapter 3, “Using the Receiver Status Screen,” in this guide
for a tutorial on how to use the status screen (shown in Figure 1-3).
A reference section that defines the different data indicated in the
status screen is also provided in Chapter 3.
