What Makes The Leica iCON GPS 70T Different?

Updated: July 4, 2018

The new Leica iCON GPS 70T combines GNSS and Inertial Measurement Unit (IMU) to deliver the first true tilt compensation solution enabling construction professionals to measure any point faster and easier without the need to hold the pole vertical and watch or level the bubble.

The Leica iCON GPS 70T is different from any other product in the market because  it does not rely on a magnetometer to correct the pole tilt for each measurement. Magnetometers are affected by metallic objects, like vehicles, iron fences and even reinforced concrete, all of which are often found on construction sites.

Different to magnetometer-based GNSS antennas, the GPS 70T’s tilt compensation does not need to be calibrated and is immune to metallic object interference thanks to the newly developed powerful and lightweight inertial micro unit (IMU), which is built into the GNSS antenna. The real-time tilt compensation combines GNSS data with the IMU’s tilt and direction values.

The Leica iCON GPS 70T is also a self-learning GNSS Smart Antenna with a high-class performance. This adaptive measurement engine with RTK plus provides measurement engineers on construction sites with the best position by automatically selecting the optimal signal combination.



With a conventional GNSS RTK rover, points such as building corners, walls, fences, light posts or points underneath obstacles, like cars, cannot be directly measured with a vertical pole. To measure a building corner for example, you would have to measure a point nearby, and apply an offset to the point or measure it with an alternative method such as a total station – both options are time consuming.

With the Leica iCON GPS 70T, a building corner can be measured directly because the pole can be tilted and the pole tip placed easily and quickly to the corner. The same goes for all other difficult to reach objects, GPS 70T literally makes measuring easier and quicker than ever before.


We certainly live in exciting times. The  Leica iCON GPS 70T can be combined with Leica iCON Site software turning complex data into realistic and workable 3D models. The GPS 70T also starts to introduce augmented reality into the field crews’ workflow as the unit measures the direction the antenna is heading and any data displayed in the 3D viewer on the controller is laid out in front of the user. This makes viewing the design in the field easier than ever before.
