Satellite Navigation About GNSS How Are the GNSS Components Simulated? User segment Finally, the receiver decodes the navigation message (ephemeris and almanac) broadcasted by the GNSS satellites, obtains information regarding the satellites orbit, clock, health etc. and calculates the satellites coordinates. The receiver also measures the signal propagation time (i.e.

Satellite Navigation About GNSS How Are the GNSS Components Simulated? Ionospheric effects You can also simulated the effect of the atmospheric (ionospheric and tropospheric) errors on the positioning accuracy. For details, see "Tropospheric and ionospheric models" on page 102. GNSS errors sources Additionally to the real-word and the ionosphere effects, you can simulate signal errors by manipulating the navigation messages of the satellites.
The simulated GNSS system depends on the installed options. For instance, if R&S SMW-K44 is installed, it is GPS C/A signal in the L1 band. For any of the GNSS systems, the simulation starts on 19.02.2014 at 6 am UTC time and satellite constellation corresponds to the one seen by a static receiver located in Munich.

Satellite Navigation Data Logging 15 Data Logging Data logging is a feature that enables you to acquire and download navigation data. Data is acquired (i.e. logged) in real time or offline. Logged data is stored in files on the hard disk, in any network directory or on a remote computer. Download and offline postprocessing of navigation data can be useful source for basic analysis, for example for validation of the received parameters, for monitoring or docu- mentation tasks.
Page 172
Satellite Navigation Data Logging The number of logged records is defined by the logged time span and by the log- ging resolution ("Log Step"). ● First logged record In real-time mode, the timestamp of the first logged record is the time indicated with the parameter "Simulation Start Time".
Satellite Navigation Data Logging Data Logging General Settings = Logging time; first record made at "Time Offset + Log Step" = Logged are 4 GPS satellites (SV IDs = 14, 15, 18, 25) = Logged parameters (not all possible are enabled) Rows 4, 5 = Difference in time between the rows 4 and 5, 8 and 9 etc.

Satellite Navigation Signal Generation Control Trigger Settings Routing and enabling a trigger The provided trigger signals are not dedicated to a particular connector. Trigger signals can be mapped to one or more globally shared USER or local T/M connectors. Use the Local and Global Connector Settings to configure the signal mapping, the polarity, the trigger threshold and the input impedance of the input connectors.
Page 197
Satellite Navigation Signal Generation Control Trigger Settings An "Arm" stops the signal generation. A subsequent trigger event (internal with or external) causes a restart. ● "Armed Retrigger" The signal is generated only when a trigger event occurs. Then the signal is gener- ated continuously.

Satellite Navigation RINEX Files RINEX Format Description B RINEX Files The RINEX file format consists of three ASCII file types: observation data file, naviga- tion message file and meteorological data file. The navigation RINEX files comprises the Ephemeris information of all visible satellites at a control station or a commercial receiver.
Satellite Navigation NMEA Scenarios C NMEA Scenarios The National Marine Electronic Association (NMEA) is a broadcasting standard sup- ported by all navigation receivers. The NMEA files comprise information about com- mon parameters related to the satellite constellation, navigation parameters, time, receiver location and dynamics.

Satellite Navigation Ionospheric Grid File Format F Ionospheric Grid File Format Customized ionospheric grids can be exported and saved as *.iono_grid files. Such files can be imported and used for the simulation of the MOPS-D0-229D iono- spheric model. If imported together with *.ems or *.nstb files, custom ionospheric grid files can also be mixed with the SBAS files, for example to create an ionospheric grid covering the entire world map.
