WEFAX receiver takes the 1691MHz input signal
and outputs an audio signal to the PROsat interface
program can thus obtain images from both the polar
orbiters and GEO sats. The program includes various

After I left
Sweden, Prof. Thomas Lindbald and Bruce Lockhart
continued to develop the ground station and went
beyond weather satellite imaging. Using a tracking
system developed by Bruce, a second dish was installed
with a motorized
rotor system that allows the dish to track
a moving satellite as it crosses the sky.

projects, e.g. for senior theses, in which the
student can learn to receive and analyse actual

in the development stage, they have succeeded
already in obtaining signals from the IMAGE

Bruce and Thomas were able to receive a signal
from Image but unfortunately they never got beyond
this to the point of decoding data from the satellite.
It was difficult to get the assistance needed
from the Image group within the time before Bruce
retired. A program at Goddard to assist student
groups in building ground stations also never
it is difficult to obtain the necessary technical
specs, hardware, and software needed to pickup
