About
GPS |
|
GPS (Global Positioning System) is developed
and maintained by the US Defence Department. The system
was initially deployed for military use but was later
open for civilian navigation. The system comprises of
24 satellites on different orbits. The GPS receiver on
the ground picks up signals from at least three satellites
and calculates its real time position by a set of mathematical
formulas generally known as “triangulation”.
GPS receivers must maintain line-of-sight with the satellites.
GPS won’t work indoor and its accuracy tends to
degrade significantly when the receiver is located under
sheltered area or near high-rise building structure or
terrain.
|
| GPS Setup |
GPS receiver needs to establish clear
line of sight to receive signals from satellites orbiting
in the space. If the receiver is placed inside a vehicle
or vessel, an extended antenna is normally required
to pick up signals beyond the enclosed area of the vehicle
or vessel. Please note that various types of I/O interface
exist among different types of pocket PC (even for the
same brand), you should ensure that the output interface
of the receiver is compatible with your pocket PC. Consult
the technical specifications or device dealer of your
receiver or pocket PC if you are in doubt about compatibility.
For Bluetooth GPS, you’ll need to setup the connection
between GPS receiver and your Device. Please follow
the manufacturer instructions and be reminded to press
‘Connect’ of GPS device before you start
using GPS |

| Position Information |
 |
1. Date/Time --- The clock
is accurate only until positioning succeeds.
2.
Vehicle Speed --- speed of vehicle by reading
GPS.
3. Vehicle direction --- The
estimate direction heading from last position.
4.
Altitude --- for 3D GPS positioning system will
need 4 good satellite signal or above.
5.
Current Position --- can be fixed only with minimum
3 or more satellites detected.
6. GPS status
--- 3 kind of status available, tick(?) for successful
position, question mark (?) for GPS warming up, cross
(X) for GPS not available.

| GPS Status |
 |
 |
 |
| Acquiring No Fix represents the GPS is achieving
position, all signals are not strong enough and
display in red. Time/date not tuned and the Pdop
value is big |
2D Positioning acquired when 3 fixed satellite
signals are in blue . |
3D Positioning acquired when 4 or more satellite
signals are fixed and the Pdop value is relatively
small. Remarks: Large PDOP value means weak signal |
|
| GPS Connection Problem |
A GPS testing program –GPS viewer
is included in the CD for checking the GPS Hardware/Software
status.
GPS Viewer Installation
Soft reset your pocket pc.
Install GPS viewer
Open GPS viewer from Pocket PC ‘Start’ ->’Program’

Press ‘Scan’, ‘FOUND GPS’ on COM7
will be displayed
After you scan the GPS, press ‘Open GPS’ to
start positioning, make sure you are on an open area.
