Working with the GPS

Tap Start / Settings / System / System Information / Wireless to

see if your unit has built-in GPS. COM2 is the dedicated hardware

port for the built-in GPS (COM1 is dedicated to the external 9-pin).

The GPS is compatible with applications that accept the NMEA

position information using a default setting of 9600 bps.

NOTE: The best GPS performance is obtained when the unit is in

the vertical position

Using A-GPS

If the GPS has been used in the prior 72 hours, Assisted GPS

(A-GPS) will retain a memory of the satellite paths. The A-GPS

satellite data is stored in memory for the satellites visible in your

current position. Therefore the Nomad can lock on the satellites

quickly, in less than 20 seconds in an open sky.

GPS settings:

If you are using only one GPS-aware application, these settings do

not need to be changed. However, to use multiple GPS-aware

applications, tap Start / Settings / System / GPS and select the

following tabs:

Access: The GPS Intermediate Driver allows multiple

applications to access the GPS receiver (disabled by default).

To enable the GPS Intermediate Driver, select the check box.

Hardware: COM2 is the hardware port dedicated for the built-in

GPS. Verify that COM2 is selected. The internal GPS

communicates at 9600 baud by default. If it has been modified

by a third party program, adjust to match the receiver baud rate.

Programs: Programs that use GPS need to know which port to

use to access GPS data. Ensure that the COM port on the GPS-

aware application is set to the same port as shown in the

Programs tab of the GPS applet. The programs port must be a

different port than the hardware port. NOTE: Some GPS-aware

applications may not communicate over GPD ports.

A-GPS: While Assisted GPS can improve time-to-first-fix, it may

reduce accuracy in some situations. Uncheck the box next to

Enable Assisted GPS and reboot your unit if you wish to

disable it.

If you are unable to connect to the GPS using the default GPS

settings, you can restore it to factory default settings by performing
