Hyperion

The Hyperion LiDAR module is part of the CityMapper systems.

Compared to the Hyperion2, the Hyperion is only capable of gated mode and can therefore only collect data in a single MPiA zone.

Sensor Misalignment Calibration

Lines for misalignment calibration

For best accuracy, 4 lines should be flown at 2000 m AGL. Two of the lines should use the flower pattern and two should use the circular pattern. They should be flown in N->S, S->N, E-W and W→E direction, see table below.

Lines for misalignment calibration need to be flown in gated mode.

Lines for verification

Also, as a verification, at least two additional lines should be flown using the circular pattern. It is possible to use production lines for verification if applicable. If two dedicated verification lines are chosen, they should be flown in opposite directions with respect to each other and have a side overlap of 100 percent. If production lines are instead used at least four lines are needed and they should have a side overlap of more than 20 percent.

Lines for verification can be flown in either gated or ungated mode.
