Factory Supplied GNSS Files

This topic provides information on the Advanced Real-time Signal Generation mode of factory supplied scenario files along with the almanac, trajectory and ephemeris files used to create the scenario files. Some of the scenarios use multiple constellations. For these scenarios, only the constellations for which an advanced license was purchased will function in the scenario. Additional scenario files are located at the "N7609B Signal Studio for Global Navigation Satellite Systems" website: www.keysight.com/find/N7609B.

Scenario Files

All of the following factory supplied scenarios were generated with the NATO model for troposphere and the Klobuchar model for ionosphere. The ionosphere parameters are listed in the following table:

Trajectory Files

Beijing.gga

This 48-minute trajectory is created by a real GPS receiver on a driving car. The GPS receiver is moving along the north segment of 4th ring road in Beijing, starting from latitude = 40.0096853333333, longitude = 116.478479666667, which is the location of Keysight Beijing Campus.

Circle.gga

This 58-minute trajectory is created by trajectory generator tool in N7609B. The GPS receiver is moving along a circular path with a radius of 1 km, centered at latitude=37, longitude= -122, at a speed of 100 km/hr.

Rect.gga

This 43-minute trajectory is created by trajectory generator tool in N7609B. The GPS receiver is moving along a 660m x 660m rectangular path, starting at latitude=38.4816929666667, longitude= -122.7121684, at a speed of 36 km/hr.
