Nesis III — Installation Manual

4.1

GNSS Signal Check

4.1

GNSS Signal Check

Nesis can show the GNSS satellite constellation and quality of the reception.
This is accessible under the

Info

icon.

1. Select

Options

on the main menu.

2. Select the

Info

icon.

3. Search for the

GNSS details

item and select it. A window like shown

on the Figure 14 will appear.

Figure 14:

An example of GPS and Glonass constellations. The satellite distri-
bution shows poor reception as most satellites appear in SE quad-
rant.

The window shows positions of the satellites on the sky. GPS constellation
is represented with disks and Glonass is represented with squares. All de-
tected positions are shown. Green color indicates satellites used in position
calculation. Grey color means that a satellite is being tracked, but it is not
being used in solution. Under unobstructed sky, satellites should be evenly
distributed.
