Prepare to use you CRUX II / BTGPS Receiver
To help you begin to use your CRUX II / BTGPSTM Receiver (“BTGPS”), read this User
Guide in the first step. This User Guide explains the detail how BTGPS operates,
functions, and common features of the BTGPS. A short glossary of GPS related terms
and abbreviations at the back of the User Guide.
Before you begin using your BTGPS, you must complete the application software
installation tasks on your host device like PAD, PDA mobile phone, MMS mobile phone,
handheld PC, and portable PC hardware. For information about the hardware
operation and application software installation, please refer to the documentation that
accompanies each product.
For operation detail information, please consult Chapter 3. In order to get more
familiar with your BTGPS, please first read Chapter 2 before starting to operate
BTGPS.
GPS signal reception
The Global Positioning System (GPS) is a space-based radio-navigation system. This
system consists of 24 satellites, which orbit the Earth at an altitude of approximately
17,500 kilometers, and ground control stations. Each of the 24 satellites, deployed in
6 orbital planes, circles the earth twice a day. The system satellites continuously
transmit signals contain the information of time and distance in a precise formation,
24 hours a day in any weather condition, everywhere around the world. By processing
the signals received, BTGPS provides users with helpful information of position,
velocity, and time for navigation and location awareness purposes anywhere anytime
on the Earth.
The BTGPS offers high position accuracy and fast Time-To-First-Fix (TTFF), which rely
on environment circumstances where receiver located as well as initial states of the
receiver. During attempting to a position fix, the receiver needs to lock on to at least
3 satellites and, uses the signal can be received as well as the data of latest position
stored in the receiver’s digital memory in order to compute the location of the device.
Environmental factors that influence the position accuracy and TTFF including such as
tall buildings,

13
narrow street and passageway,
protection film on glass,
heavy foliage,
large cliffs,
and other obstructions where the satellite signals may blocked, and, poor satellites
geometry situation. Initial state of the receiver, means latest status in memory of the
receiver, may mainly determine the time of TTFF. Position can be quickly fixed within
only 10 seconds from a hot-start state and needs 80 seconds typically from a
cold-start state. Or, might need at least 3 to 5 minutes from a completely restart-state,
for example, flying a distance over 500 kilometers from initial origin.
BTGPS uses the satellite signals to calculate an exact geodetic location through
triangulation method, contained in 10 meters CEP accurateness devoid of Selective
Availability (SA), which is good enough for general location awareness purposes. The
position data is then converted within the receiver to latitude and longitude
coordinates, which is usually provided in the geodetic datum on which GPS is based
(WGS 84). Position offsets of hundreds of meters or much more can result from using
the wrong datum.
In addition to datum used, there are number of positioning errors can occur, limiting
accuracy. The major errors including satellites orbiting error, poor satellites geometry,
multi-path signals, atmospheric delay and receiver clock timing.
The indication of GPS signal reception is described in section “Indication of BTGPS
operation” of Chapter 3.
Using optional external active antenna*
Your BTGPS is optional equipped with an external active antenna(optional accessory)
for convenience usage when operating under certain environment situation, such
inside vehicle where satellite signals are blocked. Detailed operation is described in
Operation chapter. Make sure using the optional external antenna supplied by EMTAC.
Use of unqualified antenna will severely degrade positioning performance or even
damage the receiver. Read basic guidelines before using external active antenna
accessory.
*The external active antenna is an optional accessory which not included in the standard package.

14
CAUTION and WARNING
The BTGPS contains a rechargeable Li-ion battery which supplies the power for the
operation of GPS and Bluetooth circuits inside. Care and caution must take into
account are:
zOnly use the charger supplied with the BTGPS. Use other charger can damage the
BTGPS and even dangerous at the risk of explosion.
zDo not expose BTGPS to high temperatures higher than 60°C (140°F) such in car
under direct sunshine. Expose BTGPS to high temperatures environment can not
only shorten the life of electronic devices and melt or drape certain plastics, but
also can damage the battery inside the BTGPS and even dangerous at the risk of
explosion.
zDo not try to open or break the receiver. There is no service accessory part inside
the receiver. Open the receiver will void the warranty.
