 | `3` | Level 1'e ek olarak acquisition/tracking/navigation durum gecisleri, warning/error mesajlari, integrity bilgileri ve periyodik ayrintili `[FUSION] state=...` durumu. |
 | `4` | Level 3'e ek olarak performans, scheduler, nav-bit/parser, uydu/olcum ve dusuk seviye TRACE tanilari. UART yuku en yuksek seviyedir. |
