Perairan Laut Natuna merupakan salah satu wilayah laut Indonesia yang sebagian besar wilayahnya digunakan sebagai kawasan aktifitas pelayaran. Tinggi gelombang sebagai salah satu faktor keselamatan aktifitas pelayaran perlu diketahui guna menciptakan kelancaran dalam beraktifitas. Oleh karena itu informasi mengenai karakteristik tinggi gelombang laut di Perairan Laut Natuna dibutuhkan masyarakat dalam aktifitas pelayaran. Penelitian ini telah dilakukan bertujuan untuk menggambarkan karakteristik gelombang menggunakan parameter gelombang signifikan sebagai acuan pelayaran yang terbentuk di permukaan laut dari hasil pengamatan teknologi penginderaan jauh yaitu produk satelit altimetri Jason dalam memberikan kontribusi informasi pelayaran. Data yang digunakan pada penelitian ini yaitu data satelit altimetri RADS (Radar Altimeter Database System) Jason dari tahun 2007 s.d 2016 diproses menggunakan software BRAT 4.1 dengan metode "BratAlgoFilterLoessGrid". Hasil penelitian kemudian diklasifikasikan menggunakan skala laut douglas untuk mengetahui klasifikasi karakteristik tinggi gelombang laut yang terbentuk. Berdasarkan hasil analisis komparasi data penelitian dengan data milik BMKG diketahui bahwa terdapat perbedaan hasil pengamatan tinggi gelombang laut signifikan. Terakhir hasil analisis tinggi gelombang laut didapatkan rata-rata di Perairan Laut Natuna sebesar 1,42 m dan karakteristik gelombang laut menurut skala laut douglas berada di skala 4 yaitu tinggi gelombang sedang.
