Inertial Explorer® post-processing software from our Waypoint® Products Group is a powerful and highly configurable processing engine that allows for the best possible GNSS/INS accuracy using all available GNSS data. Inertial Explorer software takes advantage of features like local base station differential processing, processing forward and reverse in time, backward smoothing and application of precise satellite clock and orbit information, to generate a much more accurate solution than is possible in real time.
Inertial Explorer integrates rate data from six degrees of freedom Inertial Measurement Unit (IMU) sensor arrays with GPS information. It is designed to utilize strapdown accelerometer (Dn) and angular rate (Dq) information to produce high rate coordinate and attitude information from a variety of IMUs, including high accuracy navigation grade to Micro Electro-Mechanical Systems (MEMS) sensor types.
Inertial Explorer runs within our familiar Waypoint GrafNav processing environment and data analysis is performed with the same plotting tools. This provides it with all of the same features available in our GrafNav. Inertial Explorer brings GNSS and IMU data together in two different ways:
It is the user’s responsibility to time tag each set of inertial measurements to the GPS time frame during the data collection process. NovAtel’s SPAN® technology offers this. For more information on SPAN, click here.
