yes, it is possible to define a MultiScanner as documented here in the Wiki. So for your application, you would add a new scanner to scanners_tls.xml, which has two "channels". For each channel, you can define a different beamOrigin with the position relative to the platform) and a rotation (rot).
This could look somewhat like this (assuming you are using something like the simple_linearpath platform):
<scanner id="navvis_vlx_3" ...> <!-- put all the scanner settings here like accuracy, wavelength, pulse frequency, max. scan angle, etc. -->
<channels>
<channel id="0">
<beamOrigin x="0" y="0" z="1.9"> <!-- the one on top -->
<rot axis="y" angle_deg="90"/> <!-- to scan horizontally -->
</beamOrigin>
</channel>
<channel id="1">
<beamOrigin x="0" y="0.3" z="1.3"> <!-- the one at the front -->
<rot axis="z" angle_deg="90"/> <!-- to scan (vertically) towards the side -->
</beamOrigin>
</channel>
</channels>
</scanner>(Not tested though 😉)
When executing the surveys, you can then add the option --splitByChannel to get one file per device or leave it out to get the merged point clouds from both devices (per leg, as always).
I hope this helps. Good luck, and just ask if you have further questions.
Best,

Describe the solution you'd like Is there a possibility in HELIOS to use 2 scanners (e.g. one horizontal with different height, and one vertical one) in one simulation ?
Describe alternatives you've considered To do 2 simulations with seperated scanners included and merging e.g. the resulted point cloud afterwards would be an alternative or ?
Additional context I want to simulate this total scanning device. (see picture below)
Thanks a lot !
