Küresel Konumlama Sistemlerinin Kullanılamadığı Durumlarda Ataletsel Navigasyon Sistemlerinin Başarımının Korunması - Preserving Accuracy of Inertial Navigation Systems in GNSS-Denied Environments

Bu bildiride, küresel konumlama sistemlerinin (KKS) elektronik karıştırma nedeniyle kullanılamadığı durumlarda özellikle elektro optik/termal (EO/IIR) arayıcı başlık veya kızılötesi hedef tespit sistemi (FLIR) gibi görüntüleyici sistemlere sahip akıllı mühimmat/füze sistemlerindeki ataletsel navigasyon sistemlerinin (ANS) göreve devam edebilmesi amacıyla yeni bir yöntem önerilmektedir. Platformun elektro-optik ya da kızılötesi görüntüleyici algılayıcısı tarafından daha önceden döşenmiş sinyal yayıcılara kilitlenilmekte ve pasif yer ölçme yöntemlerinin geliştirilerek hava platformuna uyarlanması sonucu elde edilen algoritmalar ile konum güncelleme ölçümleri yapılmaktadır. Önerilen yöntemin, önerilen konum güncelleme/kestirme algoritmaları için sinyal yayıcıların uygun yerleşimi sonucunda Ataletsel Navigasyon sisteminin (ANS) KKS olmaksızın görev yapabilme başarımını arttırdığı gösterilmiştir. In this work, a new method is proposed to improve performance of Inertial Navigation Systems (INS) of onboard missiles and smart weapons in GNSS (Global Navigation Satellite System) jamming. Previously laid beacons are used by the platform's electro-optic/infrared (EO/IIR) seeker or forward looking infrared systems (FLIR) to take bearings at them and position updates are performed by using modified survey algorithms. It is emphasized that, the proposed method along with the position update algorithms increases platform's capability to operate without GNSS aiding with the proper deployment of beacons
