A New Kinematic Algorithm For Processing Data From Stand-Alone GPS Receiver and its Ability of Determining Structural Vibrations
Abstract
In this study, detectability of high-frequency structural vibrations based on only one GNSS receiver and developed kinematic model solution was investigated. For this purpose, two data sets generated from dual frequency GNSS receiver attached on flexible steel bar(rod) which oscillates one way direction were used. Free decayed sinusoidal oscillation experiments were performed to produce both the first mode and the second mode frequency together. GNSS observations were processed by both the developed kinematic model algorithm and PPP (Precise Point Positioning) method in kinematic mode. Structural vibrations of the rod in time and frequency obtained by both methods were compared. The results have demonstrated that the developed kinematic algorithm can determine high-frequency structural vibrations as much as PPP method. Keywords : Single point kinematic solution, Kinematic-PPP, GPS.

Tek GPS Alıcısı Ölçülerinin Değerlendirilmesinde Yeni Bir Kinematik Algoritma ve Yapısal Titreşimleri Belirleme Kabiliyeti
Abstract
Bu çalışmada tek GNSS alıcısı ve geliştirilen kinematik model çözümüne dayalı yüksek frekanslı yapısal titreşimlerin belirlenebilirliği araştırılmıştır. Bu amaçla, esnek ve tek yönlü salınım yapan bir çubuk üzerinde monte edilmiş GNSS alıcısı ile üretilmiş 2 farklı titreşim veri seti kullanılmıştır. Titreşim deneyleri hem birinci mod hem de ikinci mod temel frekansları içeren sönümlü sinisoidal özellikte gerçekleştirilmiştir. GNSS ölçüleri geliştirilen kinematik model algoritması ve kinematik PPP (Precise Point Positioning) yöntemiyle değerlendirilmiştir. Çelik çubuğun her iki yöntemle elde edilen titreşimleri hem zaman hem de frekans bölgesinde incelenmiş ve karşılaştırılmıştır. Sonuçlar, geliştirilen kinematik algoritmanın yüksek frekanslı yapısal titreşimleri kinematik PPP yöntemine benzer şekilde belirleyebildiğini göstermiştir. Anahtar Kelimeler: Tek nokta kinematik çözüm, Kinematik PPP, GPS.
