SAFETY

iii

WARNING

The battery pack at the rear of the

TRIMPACK

may
contain lithium batteries. Lithium batteries contain
flammable materials and require special handling. To
prevent rupture or leakage of battery fluid, the
following safety precautions MUST be observed:

•

Do not puncture batteries.

•

Do not short circuit batteries.

•

Do not heat batteries or place them in fire.

•

Do not recharge lithium batteries.

•

Do not install batteries backwards.

•

Do not dispose of discharged batteries except

as prescribed in Federal and State regulations.

•

Do not leave loaded battery pack in the direct

sunlight for extended periods.

•

Do not leave loaded battery pack inside closed

vehicles exposed to the sun.

WARNING

The case of the TRIMPACK conducts electricity, even
though it is made of plastic. When connecting the unit to
an external power source, be careful to avoid electrical
shock just as if the case were metal.
Failure to heed these warnings may result in personal
injury or death.

iv

CAUTION

The TRIMPACK is designed for rugged use in difficult
field environments. lt will operate continuously in air
temperatures from -30° to +65°C (-22° to +150°F)
and in environments with up to 100% humidity.
However, take reasonable care of the unit as with
any other piece of high-precision equipment.

ABOUT THIS MANUAL

This manual provides information to quickly familiarize you
with the TRIMPACK and enables you to use it to perform
positioning and navigation functions. This manual is arranged
in three main parts and two appendices which describe

TRIMPACK options:

Description: describes the Global Positioning System (GPS)
and the TRIMPACK receiver, identifies the controls, indicators,
and connectors, and defines basic operations.

Operation: describes how to prepare the TRIMPACK for use,
defines the functions it can perform, and provides essential
information for each of the display formats.

Maintenance and Reference: describes operator maintenance

and provides a list of the reference datums built into the

TRIMPACK.

Appendix A: describes the Have Quick/Pulse-Per-Second
option.

Appendix B: describes the 1089-Waypoints option.
The manual is organized for ease of use. In most cases,

example screens or figures are presented on the left-hand page,
and the corresponding text is located on the right-hand page. In
the Operation section, the descriptions of the operations are
arranged in the same order as the rotary switch positions which
select them.
For clarity, the same abbreviations displayed by the TRIMPACK
are used throughout the manual; refer to the Glossary for
their meanings.
Additional detailed information is provided in the TRIMPACK
Specification, Installation, and Reference Manual, Trimble
Part No. 13498.

GPS and the TRIMPACK

GPS and the TRIMPACK

GLOBAL POSITIONING SYSTEM (GPS)

GPS is a satellite-based radio navigation system. The system
ultimately will be a constellation of 21 active satellites and 3
spares in orbits around the earth. This configuration ensures
worldwide operation with 24-hour, all-weather coverage. Each
satellite transmits data that enables GPS receivers to provide
precise position and time.

NOTE

Until the constellation is complete, coverage may be
limited to specific hours of each day in certain areas
of the world.

TRIMPACK

The TRIMPACK is a hand-held, battery-powered navigation set
that receives data from GPS satellites and calculates and
displays position, velocity, time, and navigational data. Three­dimensional fixes are obtained when tracking 4 or more
satellites; 2-dimensional fixes can be obtained from 3 satellites
and user-entered altitude.
The TRIMPACK requires line-of-sight access to the satellite

signals. Hold the unit level, with its internal antenna facing
toward the sky. GPS navigation signals are similar to light, so
anything that blocks light will block or reduce the effectiveness
of the signals. The more unobstructed view of the sky you
have, the better your set will perform. Avoid placing your
hands on or over the antenna when the TRIMPACK is in
operation.

CONTROLS and INDICATORS

DISPLAY SCREEN

The

TRIMPACK

displays information on the backlit 4-line
LCD screen. The screen contents are determined by the
rotary knob and user-selected options.

ROTARY KNOB

This 8-position switch selects the type of operation that the
unit will perform—for example: "WPT" (waypoint)
operations.

tL-Ru

(Left-Right) SWITCH

This 2-way switch is used to select items on the screen
(indicated by a flashing box). Momentarily pressing the
switch to the

left

or

right

selects different screen items.

pINC-DECq

(Increment/Decrement) SWITCH

This 2-way switch is used to walk through numbers, letters
of the alphabet, or options (as on a list). Momentarily
pressing the switch

upward

or

downward

changes the value

of the selected item on the screen.
The

pINC-DECq switch is also used as a trigger when the

selected screen item represents an action to be performed
(indicated by brackets—<action>).

Both switches automatically repeat at a rapid rate when
held

on. This feature can be used to quickly roll up to high
numbers or to scan past many screen items to select one
farther on.

BATTERY PACKS and CONNECTORS

BATTERY PACKS

Three battery packs are currently available to support
specific user requirements. To remove or install battery
packs, refer to Section 3,

Maintenance

(page 43).

Battery Pack Battery Type (Qty.) Continuous Use

13827-00 Lithium BA5800 (2) 21 hours
13828-00 AA batteries (8) 3,5 hours
13829-00 Nickel Cadmium 5 hours

(rechargeable) (16-hrs. to recharge)

CONNECTORS

•

Power: Connects to a 9 to 32V, DC power source. When

operating on batteries, the mating cap must be installed

to

enable the unit to operate.

•

Dataport:

Connects for data transfer to another

TRIMPACK, a data recorder (computer), or a digital radio

channel. When not in use, the connector's mating cap
should be installed to keep the connector clean.

•

Remote Antenna:

Refer to TRIMPACK Specification, In-
stallation, and Reference Manual for detail on cable
requirements. When not in use, its dust cover should be
installed to keep the connector clean.

OTHER OPTIONS

•

Vehicle mounting brackets are available for the

TRIMPACK

and remote antenna.

•

A neckstrap can be attached by clipping it to the holes on

both sides of the

TRIMPACK.

COORDINATE SYSTEMS

The

TRIMPACK

can display position information in any of
four coordinate systems. The desired system can be selected
from option screens in the STS knob position. Once a
coordinate system is selected, all displays use that system.
The coordinate systems are described below.

DMS: Latitude/longitude-based system, with position
expressed in degrees (°), minutes ('), and seconds (") to a
tenth of a second.

DM.: Latitude/longitude-based system, with position

expressed in degrees and minutes. Minutes are displayed to
one-thousandth of a minute in decimal form.

UTM: Universal Transverse Mercator coordinate system,
providing the grid zone and the northing and easting
component values of the position in meters.

MGRS: Military Grid Reference System, providing the
grid

zone, the grid square, and the position coordinates in

meters.

NOTE
