Populate the following settings:
No thermal noise (dBm/Hz) : On the GSG, signal strength is specified in dBm.
The Record and Playback generation relies on a decibel offset value. This offset
value maps the NMEA signal strength (in dB) to the GSG signal strength (in dBm).
An offset value of [‐160] is recommended to begin with. This value can be adjus
ted up or down until the offset is satisfactory.
Stationary period (s) : Choose to add a stationary period to your trajectory if the
movement starts immediately. If the recording already contains a stationary
period, then adding an additional one is not necessary.
SNR change threshold
: The Signal-to-noise ratio (SNR) is used to compare the
level of a desired signal to the level of the background noise. SNR is expressed in
decibels (dB) and is used to describe the GNSS signal strength in NMEA‐0183
GSV sentences.
