I would like to simulate areas where my vehicle is blocked by a building during a simulation. What is the way to model this in Skydel? ---

Hi @Yona, The best way to simulate an obstruction like buildings in Skydel is to use the antenna pattern tool. You can model an antenna sequencer (link –\> [Orolia Skydel User Manual](https://orolia.com/manuals/skydel/index.html#_sequencer)) to simulate obstructions of your vehicle while the simulation is in progress. This process can also be easily set up using the API. Regards ---

Don’t forget to consider multi-path during this testing Yona. In fact, in urban environments many vehicles are actually navigating many times with a lot of multi-path signals instead of direct line of sight. You can create 4 multi-path signals fairly easily in Skydel.
