After you tap OK – and every time you turn on MobileMapper CE - it will
automatically set the correct time as soon as it tracks the first GPS satellite.
D. Set GPS recording parameters
The GPS Settings tool is used to control the precision required for GPS positions. To
access the tool, tap Start>Programs>GPS Utilities>GPS Settings. A more complete
description is contained in the tech note “Tech Note - MMCE's GPS Settings.”
In average environments, we recommend the following default settings:
DOP Type: PDOP
Maximum PDOP: 6
Minimum SNR: 24
Elevation Mask: 15
Under tree canopy, we recommend the following less restrictive settings:
DOP Type: PDOP
Maximum PDOP: 8
Minimum SNR: 32
Elevation Mask: 10
Editing GPS settings
You may edit any field on MobileMapper CE using the buttons on the keyboard or by
using an on-screen “soft keyboard” that you display on the screen. To use the soft
keyboard, tap the screen-and-pencil icon in the Windows CE task bar. Select the
Keyboard option to make the on-screen keyboard appear. Tap on the Maximum
PDOP field, for example, and then edit the number using the on-screen keyboard.
If the keyboard obscures anything on the display, you may tap and hold on the label
bar and drag it to another location on the display.
Saving GPS settings
To save and use your selections, tap the Apply button and then the OK button.
Important: The on-screen keyboard obscures the Rest to Default and Apply buttons
on the GPS Settings screen. When you are done editing the GPS settings parameters,
you must hide the on-screen keyboard by tapping the screen-and-pencil icon in the
Windows CE task bar and selecting the Hide Input Panel option.
E. Configure MobileMapper CE for real-time DGPS corrections
To launch the DGPS Configuration utility, tap Start>Programs>GPS
Utilities>CGPS Configuration. MobileMapper CE allows you to select specific
modes of real-time differential correction. When you select a mode, the receiver will
use only this mode and will not automatically switch to some other mode if the
selected source of real-time corrections is not available. If a selected source of
corrections is unavailable, the receiver will continue to record positions, but they will
not be corrected. The DGPS modes you select are None, WAAS, EGNOS, Beacon
(i.e., MobileMapper Beacon, specifically) and Other RTCM source (usually another
type of beacon receiver).
