All our receivers are now able to compute position based on BeiDou satellites only and combined GPS+Glonass+BeiDou. Firmware is in beta stage now and soon will be released.

Below there are some graphs (with some numbers), collected in Moscow region:

Combined GPS+Glonass+BeiDou positioning (3 days long data):

• Computed position
  
  
• Example of range residuals for one Geo, one IGSO and one MEO satellite during their path
  
  
• Number of Used svs

BeiDou-only positioning (10 hours log-file with reasonable GDOP):

• Computed position
  
  
• Number of used svs
  
  
• DOPs
