SatGen software
A short Video introducing the capabilities of SatGen software can be found on the LabSat 3 SD card and also
on the LabSat 3 HDD.
SatGen software is a powerful tool for defining and creating RF playback scenario files for use with the
LabSat Simulator. For many applications LabSat 3 can record and playback real world, live sky data, but
there may be times when you need a more controlled, user definable signal. When this is the case, SatGen
provides all of the tools necessary to create a predictable, stable and accurate RF output from LabSat.
SatGen has the distinct advantage of allowing for the creation of scenarios with any dynamics, location,
date or time.
Why use SatGen software?
You might be based in Europe, but your GPS devices
will be deployed throughout the world. With SatGen
you can create a test scenario based on a user-
generated trajectory file for virtually any location,
including hostile areas for which live-sky field testing
might be impossible. This allows you to verify that
your GPS equipment design performs as required, in
a variety of locations that may be geographically
remote from your facility. It also means the same
scenario can be replayed repeatedly to see how the
device under test (DUT) performs.
Of course, LabSat 3 can record and replay live data, but creating an artificial scenario allows you to precisely
control the data content, and create a ‘gold standard’ file for carrying out true comparisons between
receivers. From your bench you can try different acceleration levels, crossing different time zones, the
equator, leap second roll-overs and many hard to replicate tests.
Artificial scenario files can easily be created from a static position, draw a route, import a file (NMEA,
Google.kml, and VBOX.vbo) and user defined instructions with inclusive pre-defined examples.
There are three versions of SatGen software available to suit a range of testing requirements. These are:
RLLSSGSW03-1 SatGen v3 Single Constellation
Create single constellation scenario files for GPS L1, GLONASS L1 or BeiDou B1¹.
RLLSSGSW03-2 SatGen v3 Dual Constellation
Create single or dual constellation scenario files for GPS L1, GLONASS L1 or BeiDou B1¹.
RLLSSGSW03-3 SatGen v3 Triple Constellation
Create single, dual or triple constellation scenario files for GPS L1, GLONASS L1 or BeiDou B1¹.
SatGen simulation software can crate RF files for ‘LabSat’ 1bit and ‘LabSat 2 or 3’ 2bit. The RF data output
can be created in static or dynamic modes: User configurable time, date and duration for static scenario
creation. SatGen v3 dynamic scenario creation with draw a route, file upload and user defined command
options.
¹ BeiDou B1 will be available in the next SatGen release as a free upgrade.
