Satellite Status

The Satellite Status panel shows a chart

indicating the strength of the satellite signals

being received by a connected GPS receiver.

The more satellites that are shown connected

and the stronger the signal (the higher the bar),

then the better the positional fix will be.

The Hdop value is a measurement of the GPS

position’s accuracy – the lower the value, the

more accurate the position. A value of 1.0 is

excellent, higher values are poorer. A value of 10

or more is very inaccurate.

If any of the bars are grey this indicates that they

are not being used by the GPS to calculate the

position. Note that this is completely within the

control of the GPS hardware, ViewRanger

cannot change which are used.

The time displayed at the top is the satellite time,

UTC. Raw GPS and sensor readings are also

shown, as is the type of the position currently

being used.

While the positioning services are trying to make a first fix, the graph may

switch between different sources.

The time, Vdop (vertical accuracy) and grey bars are not indicated on 2

edition

phones.

GPS & Navigation Settings

The Settings panel has a GPS tab containing GPS specific settings:

POI/wpt alarm Switch the alarm for arriving at a POI or waypoint on and

off.

XTE Alarm Switch the cross track error alarm on and off.

Arrival alarm

distance

When navigating, this setting determines the distance at

which ViewRanger first sounds its arrival alarm. A setting of

50m means the alarm will sound when you are within 50m

of the target point.
