Fig. 9

Average of power spectral density (PSD) of each block of kinematic coordinates. ac North (a), east (b), and up (c) PSD before (black) and after sidereal filtering (SRF) without (green) and with (red) low-pass filtering (LPF) to the sidereal filter. A cut-off period of the low-pass filter is 500-s. Two vertical thick lines indicate a period of 200 and 500 s. Solid slant lines indicate PSD of random-walk (PSD  f−2 where f is frequency) and flicker noises (PSD  f−1). df Same as ac but for GODE-GODN. gi Same as a–c but for TSK2-TSKB
