01 - VBOX Sigma Introduction
VBOX Sigma (RLVBSIGMA) is a cost-effective, RTK enabled 10 Hz data logger with integrated NTRIP modem. Its multi-
constellation, multi-frequency 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.
The in-built NTRIP modem makes it easy to receive RTK correction messages from an NTRIP network, either via Wi-Fi
or a 4G cellular connection. In order to use this type of correction you have to register and subscribe to a cellular data
plan with your local NTRIP provider, such as Topnet in the UK and Germany, Swepos in Sweden or Unavco in the USA.
