Kinematik PPP-AR ve Geleneksel PPP Yöntemlerin Performanslarının Değerlendirilmesi: Antarktika Yarımadası Örneği

PPP (Precise Point Positioning-Hassas Nokta Konumlama) yöntemi ile hem statik hem de kinematikmodda tek GNSS (Global Navigation Satellite Systems) alıcısı ile bağıl (rölatif) konum belirlemeyöntemine oldukça yakın bir seviyede konum bilgisi elde edilebilmektedir. Bu yöntem hem maliyet hemde oldukça kolay uygulanması sebebi ile beklenen doğruluk ve hassasiyeti karşılaması durumunda bağılkonum belirleme yöntemine bir alternatif olarak kullanılmaya başlanmıştır. Bu çalışmada, AntarktikaYarımadasında bulunan Livingston Island’ da bir Zodyak botu ile iki farklı günde bir dizi GNSS ölmeleriyapılmış ve GNSS verileri; bağıl yöntem, PPP-AR (Ambiguity Resolution) ve Geleneksel PPP yöntemleriyleayrı ayrı değerlendirilmiştir. PPP-AR ve Geleneksel PPP yöntemlerinin kinematik konum belirlemeperformansı bağıl yöntemle karşılaştırılmıştır. Sonuçlar PPP-AR yönteminin üstünlüğünü açıkçagöstermektedir.

Evaluating Performance of Kinematic PPP-AR and Traditional PPP Methods: Antarctic Peninsula Case

Positioning information using PPP (Precise Posint Positioning) method can be obtained with a single GNSS (Global Navigationing Satellite Systems) receiver in both static and kinematic mode at a level very similar to the Relative Positioning method. This method has been used as an alternative to the relative method in recent years since it provides both cost and ease of application and also provides the expected accuracy and sensitivity for location information. In this study, on Livingston Island, which is located in the Antarctic Peninsula, has been made a series of GNSS measurements on two different days with a Zodiac boat. GNSS data were evaluated separately by the relative method, PPP-AR (Ambiguity Resolution) and Traditional PPP methods. Kinematic positioning performance of PPP-AR and Traditional PPP method were compared with the relative method. The results clearly demonstrate the superiority of the PPP-AR method.
