Specifications and Characteristics
F-5 Operating and Programming Guide
Other Information
The standard 59551A does not include a display or a keypad. While not
necessary, it may be convenient to track the Receiver’s progress during
installation and startup by monitoring the satellites being tracked,
location (position), time and other parameters. The 59551A, however,
is supplied with a small Windows 3.1 program named SatStat (59551-
13401), which can serve to display important parameters. SatStat
operates on any PC that can run Windows 3.1, and that has an
available serial interface.
SatStat provides several useful functions. It continuously polls the
RS-232C interface and displays Receiver information most likely to be
of interest. This includes satellites being tracked along with their
elevation and azimuth, SmartClock State (locked, holdover, etc.),
antenna coordinates, time and frequency figures of merit and other
data. In addition, a clock window is provided to display time of day in
real time. Finally, SatStat allows you to easily change many receiver
parameters, such as antenna delay, by simply picking the item from a
pop-up menu and entering a new value. With SatStat and a PC,
you can monitor and control many aspects of the Receiver status
without developing software.
Achieving accurate time of day requires care in determining cable
delays, Receiver bias, position (Lat, Lon, Alt), atmospheric conditions
and other parameters which are dependent on each individual
installation.
