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 fix. 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 fix you have. Three satellites are

required for a 2D fix while four are required for a

3D fix. 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 fix is.
