+# System Integration Test: Satellite to Vision Pipeline
+
+## Summary
+Validate integration between Satellite Data Manager and vision processing layers (L2, L3).
+
+## Components Under Test
+- Satellite Data Manager
+- Coordinate Transformer
+- Global Place Recognition (L2)
+- Metric Refinement (L3)
+- Configuration Manager
+
+## Test Scenario
+Test the flow of satellite data through vision pipeline:
+1. Download satellite tiles for operational area
+2. Build Faiss index for L2 (AnyLoc)
+3. Use tiles as reference for L3 (LiteSAM)
+4. Validate GPS accuracy depends on satellite data quality
+
+## Test Cases
+
+### Test Case 1: Satellite Tile Download and Caching
+- Request tiles for AD000001-AD000010 locations
+- Verify tiles cached locally
+- Check georeferencing accuracy
+
+### Test Case 2: L2 Global Place Recognition with Satellites
+- Query L2 with AD000001.jpg
+- Verify retrieves correct satellite tile
+- Distance to ground truth < 200m
+
+### Test Case 3: L3 Metric Refinement with Satellite
+- Use AD000001.jpg and retrieved satellite tile
+- Run LiteSAM cross-view matching
+- Verify GPS accuracy < 20m
+
+### Test Case 4: Outdated Satellite Data (AC requirement)
+- Simulate outdated satellite imagery
+- Verify DINOv2 features still match
+- Accuracy may degrade but system continues
+
+### Test Case 5: Missing Satellite Tile
+- Request tile for area without coverage
+- Verify graceful failure
+- System requests alternative or skips
+
+## Success Criteria
+- Satellite tiles download and georeference correctly
+- L2 retrieves correct tiles (top-5 accuracy > 85%)
+- L3 achieves < 20m accuracy with good satellite data
+- System handles missing/outdated tiles gracefully
+
+## Maximum Expected Time
+- Tile download (10 tiles): < 60 seconds
+- Faiss index build: < 30 seconds
+- L2 queries (10): < 2 seconds
+- L3 refinements (10): < 1.5 seconds
+- Total test: < 120 seconds
+
+## Pass/Fail Criteria
+**Passes If**: Satellite data flows correctly through vision pipeline, accuracy targets met
+**Fails If**: Tile download fails, georeferencing incorrect, L2/L3 cannot use satellite data
