Sky-Plot
Diagram Sky-Plot merupakan diagram yang menjelaskan efek multipath dan efek kanduangan uap air pada data pengamatan. Diagram ini didapatkan dari pengamatan one-way (undifferenced) LC phase residual yang diproyeksikan pada bentuk diagram azimuth dan elevasi dimana lokasi titik tengah pada diagram tersebut merupakan lokasi antena pengamatan GNSS. Diagram ditampilkan setiap 4 jam dalam 1 hari pengamatan. Nilai residu yang tinggi ditempat yang sama dalam waktu yang berbeda-beda dikategorikan sebagai residu akibat multipath, sedangkan kemunculan nilai residu tinggi pada lokasi tertentu dan waktu tertentu merupakan residu akibat kandungan uap air. Lengkungan merah dan biru merupakan trek satelit, warna kuning dan hijau masing-masing menunjukan residu positif dan negative. Batang merah menunjukan skala yang dalam hal ini ditetapkan 10 mm.
Informasi Sky-Plot ini didapatkan dari hasil pemrosesan GAMIT harian.
Phase Residual Plots
Phase Residual Plots menunjukan dua hal: pertama, tampilan diagram batang residual pengamatan setiap elevasi (dalam hal ini setiap interval elevasi 10 derajat). Semakin diagram membentuk distribusi normal pada setiap interval elevasinya, menunjukan kesalahan sistematis pengamatan pada setiap interval elevasinya sudah tertangani. Kedua, tampilan menunjukan Phase vs Elevation Angle. Garis hijau menunjukan elevation-dependent noise model , titik-titik hitam menunjukan distribusi residual dari elevasi 0 derajat hingga 90 derajat, garis merah tebal menunjukan nilai residual hasil smoothing. Bentuk garis merah tebal yang tidak menyimpang dari garus hijau menunjukan tidak adanya kesalahan penggunaan model antena. Penyimpangan nilai residual pada elevasi menengah ke atas diakibatkan oleh efek atmosfer.
Informasi Phase Residual Plot ini didapatkan dari hasil pemrosesan GAMIT harian.
