IMU needs to provide a varied range of data to give Status the best opportunity to improve all those states. Red and green flash. The system is asleep. Contact OxTS support for further information Red flash. The operating system has booted but the GNSS receiver has... - Page 3 Setup Install hardware Initialise Mount the INS in/on the vehicle If using a land vehicle use “dynamic initialisation” and accelerate up to the initialisation speed (5 m/s). Ensure Position the GNSS antennas and measure the lever you maintain trajectory until initialisation is complete. arms to the INS measurement point If using a UAV ideally use “static initialisation”...
- Page 4 NOTE: This warm-up period can be further reduced by using OxTS’ combined post-processing solution. During this warm-up period, it is important to exert the INS to dynamic motion that will help to resolve any errors and unknowns in the configuration, particularly GNSS lever arm errors.
- Page 5 Validate and Commit Validate config Stop the vehicle and review the live system accuracies in NAVdisplay to ensure every state is optimised. If a configuration has been validated in previous surveys then the user will build confidence in their warm-up procedure, allowing for the survey to start almost straight away.
- Page 6 Warm-down Survey Fly your survey route, intermittently review system accuracies in NAVdisplay if a data link is available. NOTE: Avoid spending extended periods in GNSS-denied environments so that the IMU does not drift. Try to include acceleration throughout the survey to keep the kalman filter up to date.
- Page 7 Survey Warm-down (for post-process) Download data Repeat the warm-up procedure at the end of the survey It is possible to download the data from the system to provide similar linear and angular acceleration to the immediately, via NAVsolve or FTP, or later. The onboard system as the initial warm-up.
