OxTS has improved the configuration of the Inertial+ when used with the Leica GS50 GPS receiver. The new configuration means that the Inertial+ is able to follow the path reported by the GS50 much more accurately. The Leica GS50 didn’t fit the generic NMEA model used by the Inertial+ very well, particularly on its velocity measurements.
The new configuration is documented in the Leica GS50 integration manual, which can be downloaded here…
The Inertial+ transforms the output of the Leica GS50 from a low data rate to 100Hz. It removes jumps from the GS50 output and fills in gaps when the GS50 is not able to make a measurement. The Inertial+ can also measure roll, pitch and heading; these are useful for geo-referencing information from sensors.
The Inertial+ uses three gyros and three accelerometers to provide an independent measurement of position. This is blended with the measurements from the GS50 to give an optimized output. Wheel speed can be used to improve the measurements when GPS is not available. A dual antenna version of the Inertial+, the Inertial+2, can be used to improve heading measurements in low dynamic conditions.
The Inertial+ offers a very cost-effective solution to road surveying, LIDAR, aerial surveying and photogrammetry. The Inertial+ outputs its measurements in NMEA format and can be fitted between the GS50 and the end application.
The GS50 is a GIS quality GPS receiver from Leica and is popular with surveying companies. Combining the GS50 with the Inertial+can improve yield and speed up surveying particularly in mobile applications.
