Only one icon can be displayed at a time. The priority of icons,
from highest to lowest, is:
• No modem detected
• SMS message(s)
• Active or inactive connection.
For example, if you have unread SMS messages, and then
establish a data connection, the icon still displays as an unread
SMS message.
GPS Monitor window
The GPS Monitor window reports GPS data from your
modem.
The modem must have a fix on at least four satellites to report
latitude, longitude, altitude, velocity and heading. (The status
bar at the bottom of the GPS Monitor window indicates how
many satellites are being tracked.)
To open the GPS Monitor window:
1. In Watcher, select Tools > Display GPS .
‐ or ‐
Double‐click the GPS icon in the main Watcher
window (network operator dependent; this icon may not
be available).
The GPS Monitor window reports:
• Longitude and Latitude — your coordinates in degrees,
minutes, and seconds.
• Direction — your direction in degrees from true north (0),
increasing clockwise.
• Speed — calculated based on your current latitude and
longitude and the last reading (one second previous). This
is either in kilometers per hour or miles per hour,
depending on your chosen option.
• Altitude — your altitude relative to mean sea level, in
either feet or meters, depending on your chosen option.
• HEPE — Horizontal Estimated Position Error. Reflects
accuracy (horizontal/vertical precision).
