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,
narrow street and passageway,
protection film on glass,
14
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* for convenience
usage when operating under certain environment situation, such inside vehicle where

Glossary
Almanac data
A set of information that transmitted by each satellite on the orbits and state of every
satellite in the GPS constellation. Each GPS satellite contains and transmits the almanac
data set for the entire GPS satellite system network. Almanac data allows the GPS
receiver to rapidly acquire satellites shortly after it is turned on.
ACTIVE ANTENNA
An antenna that amplifies the GPS signal before it sends it to the receiver.
Altitude
The distance between the current position and the nearest point on WGS 84 reference
ellipsoid, usually it is expressed in meters or feet and is positive outside the ellipsoid.
Baud
Bits per second. Also referred to as a baud rate.
Channel
Channel refers to a set of hardware in the receiver that detects locks on and
continuously tracks the signal from a single GPS satellite. The more channels available,
the greater number of GPS satellite’s signals a receiver can simultaneously lock and
track. A receiver of 12 channels is the optimized design, considering the current
consumption, chip-package size and cost.
CEP - Circular Error Probable
CEP is the radius of a circle, centered at a true location, within which fifty percent of
positioning solutions fall. CEP is used to achieve horizontal accuracy.
C/No
Carrier-to-Noise density ratio. An indication of satellite signal strength received by the
GPS receiver.
COLD START
A condition in which the GPS receiver can arrive at a navigation solution without initial
position, time, current Ephemeris, and almanac data.
32
Constellation
Constellation refers to the specific set of of orbiting GPS satellites system, used in
calculating positions or all the satellites visible to a GPS receiver at one time. The
pattern created by the relative positioning of a GPS satellite network is designed to
achieve a very high probability of global satellite coverage even in the event of satellite
outages.
dB
Decibel. A notation of relative unit such as the satellite signal strength received.
DATUM
A math model which depicts a part of the surface of the earth. Latitude and longitude
lines on a paper map are referenced to a specific map datum. The map datum selected
on a GPS receiver needs to match the datum listed on the corresponding paper map in
order for the position readings to match.
Elevation mask
Elevation mask is an adjustable feature of GPS receivers that specifies a satellite must
be a certain number of degrees above the horizon before its signals are used for
positioning. Satellites at low elevation angles (five degrees or less) have lower signal
strengths and are more prone to loss of lock thus causing noisy solutions.
Ellipsoid
A geometric surface which all of whose plane sections are either ellipses or circles.
Ephemeris
Ephemeris is a set of parameters used by a global navigation satellite receiver to
predict the location of a satellite and its clock behavior. Each satellite contains and
transmits ephemeris data about its own orbit and clock. Ephemeris data is more
accurate than the almanac data but is applicable over a short time frame from four to
six hours. Ephemeris data is transmitted by the satellite every 30 seconds.
The predictions of current satellite position are transmitted to the user in the data
message.
Geodetic coordinate
A coordinate system whose elements are latitude, longitude and geodetic height. The
latitude is an angle based on the perpendicular to the ellipsoid. Longitude is the angle
measured in the XY plane.

GIS (Geographic Information System)
a computer based system that is capable of collecting, managing and analyzing
geographic spatial data. This capability includes storing and utilizing maps, displaying
the results of data queries and conducting spatial analysis.
Hot Start
Start mode of the GPS receiver when current position, clock offset, approximate GPS
time and current ephemeris data are all available.
L1 frequency
1575.42 MHz GPS carrier frequency which contains only encrypted P code, used
primarily to calculate signal delays caused by the ionosphere.
Latitude
A north/south measurement of position perpendicular to the earth's polar axis.
Longitude
An east/west measurement of position in relation to the Prime Meridian, an imaginary
circle that passes through the north and south poles.
Multipath
Multipath is the reception of a signal both along a direct path and along one or more
reflected paths. Multipath signals result in an incorrect pseudorange measurement.
NMEA (NATIONAL MARINE ELECTRONICS ASSOCIATION)
A U.S. standards committee that defines data message structure, contents, and
protocols to allow the GPS receiver to communicate with other pieces of electronic
equipment aboard ships.
Selective Availability (SA)
Selective Availability is a process whereby the U.S. Department of Defense dithers the
satellite clock and/or broadcasts erroneous orbital ephemeris data to create a
pseudorange error to prevent adversaries from using the extremely accurate GPS
positioning data.
SPREAD SPECTRUM
The received GPS signal is wide bandwidth and low power. The L-band signal is
modulated with a pseudo random noise code to spread the signal energy over a much
wider bandwidth than the signal information bandwidth. This provides the ability to
receive all satellites unambiguously and to give some resistance to noise and multipath.

TIME TO FIRST FIX (TTFF)
The time it takes to find the satellites is called the Time to First Fix (TTFF). If you have
not used your GPS unit for several months, the almanac data for the satellites may be
out of date. The unit is capable of recollecting this information on its own, but the
process can take several minutes. The time it takes after the user first turns on the
GPS receiver, when a GPS receiver has lost memory, or has been moved over 300 miles
from its last location.
TRIANGULATION
A method of determining the location of an unknown point, as in GPS navigation, by
using the laws of plane trigonometry.
Universal Time Coordinated (UTC)
UTC is the time as maintained by the U.S. Naval Observatory. Because of variations in
the Earth's rotation, UTC is sometimes adjusted by an integer second. The
accumulation of these adjustments compared to GPS time, which runs continuously,
has resulted in an offset between GPS time and UTC. After accounting for leap seconds
and using adjustments contained in the navigation message, GPS time can be related
to UTC within 20 nanoseconds or better. Greenwich Mean Time (GMT) is still the
standard time zone for the prime meridian (zero longitude).
Warm Start
Start mode of the GPS receiver when current position, clock offset and approximate
GPA time are input by user or by the application software. Almanac is retained, but
ephemeris data is clear.
Wide Area Augmentation System (WAAS)
Developed by the United States government, WAAS is a Satellite-Based Augmentation
System (SBAS) that calculates the errors in the GPS signal at several monitoring
stations around the country, then transmits error correction messages from
geostationary satellites to GPS receivers.
World Geodetic System 1984 (WGS 84)
The primary map datum used by GPS. Secondary datums are computed as differences
from the WGS 84 standard. WGS 84 is a set of U.S. Defense Mapping Agency (DMA)
parameters for determining global geometric and physical geodetic relationships.
Parameters include a geocentric reference ellipsoid; a coordinate system; and a gravity
field model. GPS satellite orbital information in the navigation message is referenced to
WGS 84.
