 Parameter Fields 

The following configuration parameters can be set and saved: 

 

Baud rate

:   Not applicable for the TW5210 USB version.  Leave as default 4800 baud 

 

Options: 

 

Output on fix instead of UTC second

:   

The TW5210 will immediately output NMEA sentences on acquiring a fix 

 

Enable SBAS

:   

When set and if data is currently received from an SBAS satellite, the TW5210 
includes the SBAS corrections in the calculated position. 

 

Output version info on reset

:   

The TW5210 will outputs its firmware version on reset 

Enable 1PPS output

: Not applicable for the TW5210 USB version 

1PPS on trailing edge: 

Not applicable for the TW5210 USB version

 

 

NMEA Messages

:  Select NMEA sentences to be output.  The default messages output 

are RMC GGA, VTG,GSA and GSV. 

 

GPS Mask Angle ( degrees) 

:  Sets the subtended elevation angle of a GPS satellite 

below which its data will be ignored.  The default is 4: 

 

GPS Tracking Threshold:  

This parameter sets the minimum C/N0 threshold to track a satellite. Any GPS satellite, 
with C/N0 less than the threshold value is dropped and the GPS engine searches for 
another satellite with a stronger signal level.  Increasing the tracking threshold 
decreases the GPS sensitivity, but helps prevent errors due to multipath. The value must 
be in the range 10 to 40. 

 

SBAS PRN

:  Set the SBAS satellite number to track. 

 

GGA Decimal Digits: 

 Sets the number of decimal digits output for lat and long.  The 

default is 5 but can be changed to 3 or 4
