<P>PROBLEM TO BE SOLVED: To provide a GNSS reception monitor in which reception status other than a signal level can also be confirmed and the reception status can be more easily grasped. <P>SOLUTION: A GPS reception monitor program displays a reception status display screen 30 on a display device of a computer. The reception status display screen 30 displays a sky plot display section 31, a signal level display section 32, a positioning result display section 33 and a correlation graph display section 34 side by side. The sky plot display section 31 displays a position of each GPS satellite. The signal level display section 32 displays a level of a signal received from each GPS satellite. The positioning result display section 33 displays a result of positioning based on signals received from at least a part of GPS satellites. The correlation graph display section 34 displays a correlation graph obtained by plotting a correlation value between the signal from each GPS satellite and a replica code with respect to a frequency and a phase of the replica code. <P>COPYRIGHT: (C)2012,JPO&INPIT |
