I would like to know what are the measurement units of Range, Skip and Track trail parameters in simulation configuration section.
thank you for reporting this.
The units for the fields shown in the Simulation panel are:
max radius for circle and spiral or side/2 for square in degrees
is the step for angular movement in degrees. Since tick period is constant, skipping plot steps increases speed. So it's used to adjust speed of movement.
how many track points to keep on screen. It affects only the display, not the gps results. If you decrease this number you get a short lived trail. Try 36 with the spiral shape to see the results.
I'll put the units next to the values in the next release.
