Sky Plot diagram of the Mission Planning dialog
Mission Planning dialog calculates the
observation conditions, such as satellites visibility and PDOP values for survey anywhere in the world.
MAGNET Field presents the calculated satellite observation conditions as four diagrams. Select a diagram to display from the drop-down list in the dialog's top right corner.
- Sky Plot - displays the satellites positions on the sky plot during the planned mission time (this diagram).
- Sat List - displays the specific satellite visibility on the planned mission time line.
- Sat Num - displays the quantity of visible satellites for every constellation on the planned mission time line.
- PDOP - displays the PDOP values on the planned mission time line.
To represent graphically the position of the satellites during the planned mission time.
- Displayed diagram represents the geographically oriented sky plot with its center defined by the mission planning point coordinates. To change the mission planning point coordinates, click
in the title bar, open the Mission Planning Setting dialog and measure or enter coordinates.
- Outer circle line is the horizon line.
- Bold circle line is the elevation mask line. Navigation satellites outside this line aren't observed, don't display, and will not be used in measurements. To customize the elevation mask, click
in the title bar, open the Mission Planning Setting dialog and enter required value.
- Observed satellites are shown according to their position on the sky plot during the planned mission. Color of a satellite is the color of the constellation this satellite belongs to. The satellite number also displays next to its respective icon.
- Use constellation icons above to display / hide its satellites. Each icon displays the number of visible satellites for the constellation. Click the icon to display / hide the constellation on the sky plot:
-
/
- GPS satellites constellation hide / display;
-
/
- GLONASS satellites constellation hide / display;
-
/
- Galileo satellites constellation hide / display;
-
/
- BeiDou satellites constellation hide / display;
-
/
- SBAS satellites constellation hide / display;
-
/
- QZSS satellites constellation hide / display;
-
/
- NavIC satellites constellation hide / display.
- Use the following buttons to manage the planned mission time line and to update the satellites positions for every ten-minute interval of the planned mission:
-
- return to the start time of the planned mission;
-
- move the time line backward with ten-minute intervals;
-
- move the time line forward with ten-minute intervals;
-
- pause the time line at any ten-minute interval.
- The diagram also displays:
- PDOP - the PDOP value for selected calculation moment.
- Local - the date and local time of selected calculation moment.
- Coordinates - the mission planning point coordinates in the job's coordinate system.
