 ## GPS-Denied Configuration
 
 In MAVProxy console:
 
 ```bash
-# Disable all pre-arm checks
+param set ARMING_CHECK 0   # Disable pre-arm checks
-param set ARMING_CHECK 0
-
-# GPS-free flight modes
 mode stabilize             # Manual with stabilization
-mode alt_hold       # Altitude hold
+arm throttle force         # Force arm
-mode guided_nogps   # Guided without GPS
 ```
 
 ## GPU Support
 
-The launcher auto-detects your GPU:
+Auto-detects: NVIDIA > Intel > AMD > Software
 
-| GPU | Status |
+Check your GPU:
-|-----|--------|
-| NVIDIA | Best performance |
-| Intel integrated | Good for laptops |
-| AMD | Good performance |
-| Software | Works but slow |

 ## Troubleshooting
 
+### "No JSON sensor message"
+
+Gazebo isn't sending data to SITL. Check:
+1. Start Gazebo FIRST, then SITL
+2. Plugin path is set:
+```bash
+echo $GZ_SIM_SYSTEM_PLUGIN_PATH | grep ardupilot
+```
+
 ### Simulation laggy
+
+Check GPU is being used (not software):
 ```bash
 glxinfo | grep "OpenGL renderer"
-# Should show GPU, not "llvmpipe"
+# Should NOT show "llvmpipe"
 ```
 
 ### Can't arm
+
 ```bash
 param set ARMING_CHECK 0
 arm throttle force
 ```
-
-### No camera
-Use `./scripts/run_ardupilot_sim.sh camera` for camera world.
