Connect to your GNSS receiver
- From the home screen, select Setup.
- Next, select Mission Planning
Once connected to your receiver you can do one of the following:
- Click on the icon to get the coordinates from the connected receiver. Click the "X" to stop.
- Or, type in new coordinates or edit coordinates.
- Using the arrows, specify the date, start time and end time of planned observations.
- Click the green check to save your configuration.
Sky Plot
- Once you click the green check, the Mission Planning Setting dialog is closed.
- The Mission Planning dialog will calculate and show the position of satellites in the first ten minutes of the specified time on the Sky Plot (the celestial sphere).
- Click > or < to move forwards or backwards 10 min, respectively
- Click I< to return to start from the beginning
- Click II to pause at any ten-minute interval
- To view different graphical views, click on the dropdown menu to switch between Sky Plot, Satellite List, Satellite Number, and PDOP.
Satellite List
- Satellite List: Select the colored satellite icons to see when particular satellites will be visible. Different options will be available depending on your receiver and OAF.
Satellite Number
- Sat Num: number of satellites visible during that period of time. Ideally, you want to aim for times where you have more than 5 satellites.
PDOP
- PDOP: Position (3D) dilution of precision. This value represents the effect of the geometry of the satellites on the resulting precision. Low values mean a higher level of confidence in accuracy.
- Use the different views to calculate and determine the right time to do a GNSS survey. Look for periods of time with a high satellite count, low PDOP, and good satellite coverage (satellites in all 4 quadrants).
- NOTE: this is for GNSS receivers only.
