In addition to our other GNSS/INS products, we offer GNSS/INS modules that feature an integrated Real-Time Kinematic (RTK) GNSS receiver. Using RTK makes the position estimate of the GNSS receiver more accurate. By using RTK, you can improve your positional data from meter-level accuracy to centimeter-level accuracy. The added benefit of an external RTK model is that it can handle and process high-accuracy position data from external receivers.
A RTK is your best choice if you are in need of the following data:
3D acceleration, 3D rate of turn, 3D magnetic field
Free acceleration (no gravity component)
Roll/pitch (inclination)
Yaw (relative/gyro-based) or Yaw (absolute/magnetic North-referenced)
Latitude, longitude, altitude
3D velocity
Solving unknowns to mitigate error
With standard GNSS, a variety of error sources can cause significant inaccuracies in the estimated position of the receiver. This is because the GNSS uses the estimation of the pseudo-range between satellites and receivers to determine the receiver’s 3D position on earth. Clock errors between the GNSS satellite and GNSS receiver as small as one microsecond will produce an error of 300 meters. By establishing a GNSS fix with four or more satellites at the same time, an RTK receiver can solve for four unknowns: its 3D position and its clock error with respect to the global time.
Atmospheric delays and inconsistencies distorting the radio signals between receiver and satellite are another source of error in standard GNSS position estimation. An RTK GNSS collects correction information to mitigate these errors.
