What is the difference between the new Trimble TIP technology and the legacy Trimble SurePoint tilt compensation technology found in the Trimble R10 and R12?
Trimble® TIP™ technology uses an Inertial Measurement Unit (IMU) comprised of three accelerometers and three gyroscopes to provide the necessary information for the positioning engine to precisely determine the attitude of the rover, allowing the tilt heading and thus the position of the pole tip to be computed in real time.
On the other hand, Trimble SurePoint™ technology, first introduced in the Trimble R10, uses a magnetometer to determine the tilt heading. Because the heading provided by the magnetometer depends on an accurate global model of the earth's magnetic field, and because the sensor itself is susceptible to local sources of magnetic interference which can render it unusable, the achievable tilt angle is less (15°), compensated points cannot be measured in all instances, and the system must remain static when measuring a compensated point. It is therefore also not possible to use Trimble SurePoint technology for stakeout, whereas Trimble TIP technology doesn't require the system to remain static and is therefore suitable for both measurement and stakeout workflows.
Finally, because Trimble TIP technology uses sensor data to automatically align the IMU to the GNSS reference frame in the field, it is not necessary to perform specific steps to calibrate the sensors, as is the case with the Trimble R10 and Trimble SurePoint technology.
