NAVIGATOR DAB/DAB+/T-DMB

Mobile measurement campaigns, driving or on foot, with GPS Positioning



Navigator DAB/DAB+/T-DMB has been designed to perform mobile measurement campaigns for DAB, DAB+ and T-DMB networks. This handheld equipment can be used in a vehicle, or on foot (indoor or outdoor).
The campaign can be dedicated to a single channel (frequency) or for multiple channels (sequential measurement).

The main measurement functions are the following:

  • Real time measurements and display of RF and data structure analysis.
  • Automatic logging of measurement data with GPS position on the internal hard disk. 
  • Audio real-time decoding.
  • Map-based display of the measurement data.
  • In-depth post processing with filtering possibilities and automatic data export (Google Earth, LS Telcom…)

Scanning of band 3 and L-band



The Navigator DAB/DAB+/T-DMB can perform a scan of the frequency band to automatically detect the available multiplex channels.


Data export



The recorded measurement data can be exported as a CSV file (Excel compatible), to  map software (Google Earth, MapPoint…) or to radio spectrum planning software (like ATDI, LS Telcom…) in order to compare the predicted coverage with measured data obtained in a real world environment.


Campaign analysis with GoldenEye


Campaign representation

  • During a campaign, all the measurements (with their GPS position, if available) are logged and stored on the internal hard drive. The campaign file containing all this data can then be downloaded onto a PC and opened with GoldenEye.
  • GoldenEye creates a geographical representation of the campaign with a different color for each level value (or field strength). Clicking on a point, you get information such as the modulation parameters and the speed.
  • In the “Superimposed” tab, GoldenEye plots level curves. If the campaign contains data from several multiplexes, the curves can be superimposed for easy comparison.
  • All details of each measurement point can be found in the measurement table (GPS position, SNR, BER,  …)
