GPS Data Screen - it tells you which satellites your GPS is talking to

Tap the little Satellite icon on the Main Menu, or in the Cockpit or the Map screen, to open the GPS Data Screen where you can immediately see how many satellites you are (and are not) receiving.

The first time your turn your GPS on, when you haven't had satellite connection before, this screen will look very uninteresting - a dark grey circle with N S E W compass points on a light grey background (your virtual sky) and blank spaces underneath Accuracy, Elevation, Speed, Position and Date/Time.  The flashing green light indicates your GPS connection module is working and is just waiting to 'talk' to the satellites - but it doesn't know where it is. The red colour around the Satellite icon confirms your GPS is not yet talking to the satellites.

Take your GPS outside in the sun so it can map the satellites in the sky and establish connection (this will take up to 15 minutes). As soon as your GPS has full satellite connection, the screen takes a completely different look - it has little green, grey and red circles inside the larger grey circle, there are figures that make sense inside all the white boxes, and there is a black or grey shading in the boxes on the RHS next to each satellite's number.

The GPS Data Displayed in your virtual sky.

Your virtual sky on the left of the screen represents the currently visible part of the sky above you, with your position in the middle.

Your GPS receives data from both the green and the grey satellites. It uses only the data from the green ones to calculate your current location - it receives the data from the grey ones but doesn't use it. It cannot receive data from any red satellites. If you lose signal eg go indoors, you will see the green satellites change colour to red. They will change back to green again as soon as you go outside again (or into a position where you can get satellite reception).

On the right you can see the satellite signal strength bars. Black bars are for green satellites, grey bars are for grey satellites. The more satellites your GPS tracks (the green ones), the better your calcualted position will be. You need five green satellites for your GPS to define your position.

With five or more green satellites, your screen now shows the current time and date (as long as you have set your local time zone correctly), plus your current lattitude and longitude, height above sea level and an approximate speed.

Note: Accuracy can be affected by several atmospheric and other factors that the GPS cannot take into account. Use this accuracy information only as an estimate.

Note: your GPS connection indicator should always flash green - whether you have satellite connection or not. In the very unlikely event of it flashing yellow or red, please contact Logic Gear Customer Service
