GPS/GNSS

Allegro 2 Geo models have GPS/GNSS with 2 to 5 meter

accuracy.

Using GPS/GNSS

To use GPS/GNSS, tap on the GPS/GNSS status gadget to

turn it on. The GPS/GNSS starts looking for satellites to use for

a x. The green LED on the keyboard blinks periodically, and

a satellite icon is placed on the title top bar.

Once enough satellites are found, information similar to the

following is shown:

5 SV The number of satellites used for the current

position.

3Diff The type of x you have. Three satellites are

required for a 2D x while four are required for a

3D x. 3Diff means an SBAS (WAAS/EGNOS/MSAS)

signal is being used for the GPS/GNSS solution.

PDOP A measure of accuracy. The lower the number,

the more accurate the x is.
