Hassas Nokta Konumlama (PPP) Tekniğinin Ağaçlık Alanlardaki Konum Belirleme Performansının CSRS-PPP Yazılımı Kullanılarak İncelenmesi [PDF]
Afyon Kocatepe University Journal of Sciences and Engineering, 2023 GNSS teknolojisi, orman kaynaklarının araştırılması ve izlenmesi için güçlü bir araç haline gelmiştir. Ancak, ormanlık/ağaçlık alanlarda orman örtüsü GNSS sinyalleri ve uydu sayısı üzerinde olumsuz etkiye sahiptir. Bu yüzden hassas konum belirlemek mümkün olmayabilmektedir.
