GPS Intermediate Driver
GPS Receiver Access for Multiple Programs
The GPS Intermediate Driver (GPSID) is used to allow more
than one program to use data from the GPS receiver. The GPS
Settings control panel controls how the GPSID is used. Internal
GPS is on COM7 and communicates at 38400 baud. These
settings are found on the Hardware page of the GPS Settings
control panel. If another GPS receiver is to be used, this is
where you connect that GPS receiver so that the GPSID can
access it.
The GPSID can output data on another COM port in a way that
allows multiple programs to access the same COM port. This is
called the Program Port and defaults to COM2. This can be set
up on the Programs page of the GPS Settings control panel.
The camera, GPS function and GPS compass function use
the GPSID to obtain GPS information. Turning off the GPSID
through the hardware port disables these functions.
NOTE: If an application accesses the GPS module directly on COM7,
the GPSID will not have access to the GPS. This prevents the camera
geotag and GPS from functioning.
GPS Accuracy
The GPS antenna is in the extended antenna bumper. Don’t
put your hand or another object over the cap. This will reduce
accuracy. The more items between you and satellites, the lower
the accuracy will be.
GPS Compass
The GPS compass is a simple navigation tool. You can set a
waypoint and navigate back to that location. To use the compass,
tap on the compass gadget. This activates the GPS function
if it is not already on. Wait until you have a fix. You need to
move in a line to get direction information.
