+# Summary: Geophysical Measurement Configuration for strapdown-sim
+
+## Changes Made
+
+This update adds interactive configuration support for geophysical measurements (gravity and magnetic anomaly) to the `strapdown-sim config` command.
+
+### 1. Core Library Changes (`core/src/sim.rs`)
+
+#### Added `geophysical` field to `SimulationConfig`
+- New optional field: `pub geophysical: Option<GeophysicalConfig>`
+- Updated `Default` implementation to include `geophysical: None`
+- This allows the main simulation configuration to include geophysical parameters
+
+### 2. CLI Changes (`sim/src/main.rs`)
+
+#### New Prompt Functions
+Added five new interactive prompt functions:
+
+1. **`prompt_enable_geophysical()`** - Asks if user wants to enable geophysical navigation
+2. **`prompt_geo_resolution(measurement_type: &str)`** - Prompts for map resolution (15 options from 1° to 1")
+3. **`prompt_gravity_config()`** - Configures gravity anomaly measurements:
+   - Map resolution
+   - Measurement bias (mGal)
+   - Noise standard deviation (mGal, default: 100.0)
+   - Map file path (optional, auto-detect if empty)
+4. **`prompt_magnetic_config()`** - Configures magnetic anomaly measurements:
+   - Map resolution
+   - Measurement bias (nT)
+   - Noise standard deviation (nT, default: 150.0)
+   - Map file path (optional, auto-detect if empty)
+5. **`prompt_geo_measurement_frequency()`** - Sets measurement frequency in seconds
+
+#### Updated `create_config_file()` Function
+- Added "Geophysical Navigation Configuration" section
+- Calls new prompt functions after GNSS degradation config
+- Validates that at least one measurement type is enabled
+- Builds and includes `GeophysicalConfig` in final `SimulationConfig`
+
+### 3. Documentation
+
+#### New Documentation File (`docs/GEOPHYSICAL_CONFIG.md`)
+Comprehensive guide covering:
+- Overview of geophysical configuration
+- Step-by-step wizard usage
+- Configuration file format
+- Available resolution options
+- Default values
+- Example usage
+- Notes and requirements
+
+### 4. Example Configuration (`examples/configs/geonav_example.toml`)
+Complete example configuration demonstrating:
+- Gravity anomaly measurements setup
+- Magnetic anomaly measurements setup
+- Integration with closed-loop simulation
+- TOML format with comments
+
+### 5. Test Script (`test_geo_config_wizard.sh`)
+Automated test script to verify the wizard functionality with simulated user input.
+
+## Features
+
+### User-Friendly Configuration
+- Interactive prompts with clear options
+- Default values for common parameters
+- Input validation with helpful error messages
+- Option to quit at any point with 'q'
+
+### Flexible Measurement Configuration
+- Enable/disable gravity measurements independently
+- Enable/disable magnetic measurements independently
+- Must enable at least one type if geophysical navigation is activated
+- Auto-detection of map files if not specified
+
+### Resolution Options
+15 resolution levels available for both gravity and magnetic maps:
+- From coarse (1 degree) to fine (1 arcsecond)
+- Default: One Minute (good balance of accuracy and file size)
+
+### Integration with Existing Workflow
+- Seamlessly integrated into existing config wizard
+- Follows same patterns as other configuration sections
+- Compatible with all simulation modes
+- Works with existing TOML/JSON/YAML config formats
+
+## Usage Example
+
+```bash
+# Run the configuration wizard
+strapdown-sim config
+
+# When prompted:
+# 1. Enable geophysical navigation: y
+# 2. Enable gravity measurements: y
+#    - Select resolution: 11 (OneMinute)
+#    - Set bias: 0.0
+#    - Set noise std: 100.0
+#    - Map file: (press Enter for auto-detect)
+# 3. Enable magnetic measurements: y
+#    - Select resolution: 11 (OneMinute)
+#    - Set bias: 0.0
+#    - Set noise std: 150.0
+#    - Map file: (press Enter for auto-detect)
+# 4. Set measurement frequency: 1.0 (seconds)
+
+# Use the generated config
+strapdown-sim --config your_config.toml
+```
+
+## Configuration File Example
+
+```toml
+[geophysical]
+gravity_resolution = "OneMinute"
+gravity_bias = 0.0
+gravity_noise_std = 100.0
+magnetic_resolution = "OneMinute"
+magnetic_bias = 0.0
+magnetic_noise_std = 150.0
+geo_frequency_s = 1.0
+```
+
+## Benefits
+
+1. **Easier Setup**: No need to manually edit configuration files for geophysical measurements
+2. **Reduced Errors**: Input validation prevents common configuration mistakes
+3. **Better UX**: Interactive wizard guides users through all options
+4. **Documentation**: Clear prompts explain each parameter
+5. **Flexibility**: Users can enable only the measurements they need
+
+## Testing
+
+- ✅ Code compiles without errors
+- ✅ No clippy warnings in modified files
+- ✅ All existing tests pass
+- ✅ Markdown documentation passes linting
+- ✅ Integration with existing config wizard verified

+## Files Modified
+
+1. `/home/james/Code/strapdown-rs/core/src/sim.rs`
+2. `/home/james/Code/strapdown-rs/sim/src/main.rs`
+
+## Files Added
+
+1. `/home/james/Code/strapdown-rs/docs/GEOPHYSICAL_CONFIG.md`
+2. `/home/james/Code/strapdown-rs/examples/configs/geonav_example.toml`
+3. `/home/james/Code/strapdown-rs/test_geo_config_wizard.sh`
+
+## Next Steps
+
+Users can now:
+1. Run `strapdown-sim config` to create configurations with geophysical measurements
+2. Refer to `docs/GEOPHYSICAL_CONFIG.md` for detailed documentation
+3. Use `examples/configs/geonav_example.toml` as a template
+4. Test the wizard with `test_geo_config_wizard.sh`
