  • Page 2 GNSS engine offers outstanding RTK performance even in areas with poor and multi-path satellite coverage. When used in conjunction with an RTK base station or NTRIP correction service, VBOX Sigma is accurate to within a centimetre and is the ideal reference for ground truth.
  • Page 3 • Data Recording - VBOX Sigma records data at 10 Hz and saved it to an SD card for data analysis. • CAN Bus Output - VBOX Sigma has a CAN Bus output for connection to a 3rd party data logger or another device.
  • Page 4 When comparing two signals, we are measuring a time delay of about ~0.07 s. This is the time delay from satellite to receiver, which is about 20,000 km. https://en.racelogic.support//Product_Info/VBOX_Data_Loggers/VBOX_Sigma/VBOX_Sigma_User_Guide/01_- _VBOX_Sigma_Introduction...
  • Page 5 This means that the positional accuracy when using corrected GNSS signals (called code-phase signals) alone is around 0.5 m. To obtain a higher level of accuracy, up to 1 cm, another technique needs to be used in conjunction. https://en.racelogic.support//Product_Info/VBOX_Data_Loggers/VBOX_Sigma/VBOX_Sigma_User_Guide/01_- _VBOX_Sigma_Introduction...
