GPS PC Data Path

A diagram of the data path for pre-processing can be seen in Figure 3. This figure shows the
programs and functions that operate on the user supplied data to generate the data for the FPGA.
Most of these programs were supplied by Tracking and Imaging Systems, Inc. Several attempts
were made to shorten the data generation process, such as generating the Position file from the
Traj program directly in ECEF and obtaining a line-of-sight distance output from the EnRAP
v9.0b program. Neither of these methods worked as desired, as the data did not match what was
9
generated by the original data path. These are calculations that are possible to perform, but there
is some error in the current implementations.
