Hi @bastianhjaeger, what's the status of this PR? The code to add ToElement looks good, but making NavSat on actors work might need more work in gz-sim.

Thanks for the contribution, but since there hasn't been any updates for a while, I'll remove it from the Jetty milestone. But please don't let this stop you from pushing on this PR. Once the initial feature freeze window is over, we'll be able to merge this.
