Mission Planning

Sometimes when working under canopy (urban or forest) there will be periods during the day when
the Rover will be unable or very slow to FIX. These unproductive periods can easily be predicted

using ‘Online Mission Planning’.

While not usually necessary when working in open conditions, high

canopy and multipath can make Mission Planning worthwhile.

There are many web and computer Based mission planning tools. The online resource

https://www.gnssplanningonline.com/

is used for this example.

First configure the settings: pay attention to the ‘Time Zone’ and approximate job

elevation. Set the

‘Elevation Cutoff’ to a high value like 25

- 30 degrees to simulate heavy canopy. Check GPS,

GLONASS and Galileo leaving BeiDou unchecked (as it probably will have minimal contribution.) Click

‘Apply’.

Click on ‘Charts’ and roll down to the PDOP chart:
