Abstract: For many applications, access to unbiased or error-controlled Global
Positioning System (GPS) observations can be very useful. This paper is devoted
to the description of the simulated GPS observation generator (SiGOG), a
software that simulates GPS observations. It presents the results of tests
of SiGOG accuracy using GPS processing software, and demonstrates its
successful performance as a differential GPS (DGPS) correction provider.
Note: There are two Fortran 77 programs available here: SIGOGbcst.for, which
creates simulated observations output to a RINEX observation file using a
GPS broadcast ephemeris and user-defined site coordinates and antenna offsets;
and SIGOGprcs.for, which does the same but uses three sequential precise ephemerides
in SP3-a format for the input orbit data.
