Preface

W elcome to the Series 4 000 Recei ver Ref erence manual. This manual
describes all current models in the T r imble Serie s 4000 group of GPS
receiv ers. Thes e receivers are designed fo r a v ari ety of ap plica tions in
the areas of surveying, positioning, and navigation, but they share
many hardware and firmware components, and they behave alike in
many respects.

Scope and Audience

Even if you have used other Global Positioning System (GPS)
receivers we recommend that you spend some time reading this
manual. This manual provides detailed reference information about
members of Series 4000 GPS receivers. It assumes that you already
are familiar with the basic procedures for operating your receiver. If
you are not yet familiar with the receiver, see the first few chapters of
its User Guide.

This manual also assumes that you understand the application for
which you intend to use your receiver.

Series 4000 Receiver Reference xxi

Preface

You should be familiar with the principles of the
Positioni ng System (GP S), and with the terminology that is us ed to
discuss it. For example, you should understand such terms as space
vehicle (SV), elevation mask, and dilution of precision (DOP). If you
are not familiar with the
Trimble's booklet GPS, A Guide to the Next Utility. You can find a
complete citation t o tha t publi catio n in the Bibl iogra ph y at the end of
this manual.

To download and postprocess logged data, you should know how to
use personal computers runni ng the IBM DOS or MS-DOS operating
system. You should be able to run programs, create and use
directories, and use common DOS commands for cop ying, renamin g,
and deleting files.

The following section provides you with a guide to this manual, as
well as to other documentation included with this product.

Notes on Termino log y

Series 4000 receivers are used in several different applications that
have developed independently of each other, and this has led to a
certain amount of inconsistent terminology. For example, in static
surveying the point that a receiver's GPS antenna occupies during a
satellite observation has traditionally been called a station; in
FastStatic surveying it has been called a mark, and in kinematic
surveying it has been called a point.

NAVSTAR GPS

NA VSTAR

Global

, we suggest that you read

Trimble's documentation has adopted a consistent set of terms as far
as it is practical to do so. For the present, this will lead to some
inconsistency between documentation and equipment. For example,
documentation consistently uses the term mark for a point whose
coordinates are t o be determined, but the s tatic surveying procedure's
receiver screens continue to say station. Fut ure releases of software
will reduce or eliminate these inconsistencies.

xxii Series 4000 Receiver Reference

The first chapter of the Series 4000 Application Guide summarizes
the major changes in ter minology. These terms and others are defined
in the Glossa ry near the end of this manual.

How to Use the Series 4000 Manuals

Each Series 4000 GPS receiver is accompanied by several pieces of
documentation:

•

A User Gu i de introduces the recei ver and describ es those of its
features that are not shared by other members of the Series

4000.

•

The Series 4000 Receiver Reference (this document) describes
all features found in Series 4000 receivers, in complete detail.
It is useful when you need to know exactly how a particular
key or data display works, or you need technical information
about a receiver's power requirements, inputs, or outputs.

•

The Series 4000 Application Guide explains the applications
that Series 4000 receivers may be used for, such as FastStatic
surveying, navigation, and real-time positioning with
differential GPS. It discusses the purpose of each procedure,
explains how to perform the procedure, and gives suggestions
for planning the procedure and configuring the receiver.

Preface

•

Once you are familiar with the basics of using a receiver, the
Application Guide and the Quick Reference (below) should
ordinarily be the only pieces of documentation you need to
take into the fie ld.

•

A set of Series 4000 Quick References summarize the
procedures most often performed with each receiver. They are
much less detailed than the Application Guide, but their
compact format makes them very convenient to carry in your
shirt pocket or backpack.

manual. For more detailed descriptions of an individual receiver, see
that receiver's User Guide.

Series 4000 Receiver Reference 1-1

The Series 4000 Receivers

1.1 “Maxwell” Technology

The latest generation of Series 4000 receivers feature Trimble's
proprietary Maxwell technology, which provides more precise
position measurements by means of very low-noise C/A code
processing. In differential GPS (DGPS) applications, Maxwell
technology increa ses the prec ision of posi tion f ixe s from ±2--2-5 meters
RMS horizontal to bett er than ±1 meter. Also, the precisi on of car rier
phase measurement has been increased nearly to its theoretical limit.

The following model descriptions tell which receivers use Maxwell
technology.

1.2 Super-trakTM Technology

4000SSi series receivers feature Trimble’s Super-trak technology.
Super-trak ena bles acqu irin g lo w po wer sate llit e signal s, main taini ng
better lock on si gnal s once acquired and tracking unde r c ondi ti ons of
high RF interference. Super-trak is a combination of hardware and
firmware technology, including true multibit signal processing.
Performance tests show significantly improved jamming immunity
over lesser equipped receivers. Another system benefit is
measurement of the L2 range during P-code encryption. Receivers
with the SSi designation use Super-trak technology.

1.3 Dual-Frequency Surveying Receivers

Dual-frequency receivers (those equipped with the Dual Frequency
Option) observe satellite measurements on both the L1 and the L2
frequencies. They thus can perform FastStatic surveys and RTK
surveys (with the RTK Functions Option), as well as static and
kinematic surveys.

1-2 Series 4000 Receiver Reference

1

By measuring transmission time differences between the two
frequencies, dual-frequency receivers can compensate for
measurement errors due to atmospheric delay. They also produce
cleaner, lower-noise measurements than single-frequency receivers.
These features make them particularly useful for control surveying
and other applications that demand very accurate results over long
distances. Dual-frequency receivers also can operate under more
difficult conditions, such as interference caused by high ionospheric
activity.

The Series 4000 Receivers

The

4000SSE Site Surveyor

9 channels of L1 P-code and carrier phase, and 9 channels of L2 P­code and carrier phase. During periods when Anti-spoofing is active,
it uses L1/L2 cross-correlation to derive information from the
encrypted P-code. This receiver is capable of performing real-time
surveys. The system provides centimeter accuracy positions in real
time. It is suitable for short range control (up to 10 km), topographic
surveys and stake out operations. Real-time kinematic firmware is a
standard feature.

The

4000SSE Land Surveyor IID

provides carrier phase measurement on both L1 and L2, and P-code
measurement on L2 only. During periods when the Department of
Defense's Anti-Spoofing mode is active, it uses half-wave L2
processing to derive information from the L2 signal. It provides
economical dual-frequency measurement for surveying applications
that do not require more sophisticated features.

The keys to the left and right of the LCD (Figure 2-1 or Figure 2-2,
upper half) are closely tied to the operation of the LCD display itself.

The [<] and [>] keys move the underline cursor left or right on the
display. Press one of these keys briefly to move the cursor one
position, or hold it down for fast repeat movement.

The four softkeys to the right of the display perform different
functions at different times. The function labels fo r the softkeys are
displayed on the right side of the LCD. For example, the following
screen shows labels for the first, second, and fourth softkeys. (In this
example the third softkey has no function.)

example, you would press

The cursor skips over the degree and minute signs and the decimal
point, which the keyboard does not change. Therefore, to enter a
value with leading zeros you must enter the zeros. To enter

Each display is grouped into columns, each column
representing an SV on one receiver channel. For each channel, the
four lines show:

1. Which SV the channel is currently tracking or searching for.

URA (User Range Accuracy) is a measure of the errors that
may be introduced by Selecti v e A v aila bility and sate llite healt h
problems. Each SV's URA is set by the

NA VSTAR

system's
ground support (the Control Segment). The larger the number,
the larger the errors that are likely to occur when that satellite
is used to compute positions autonomously. A URA of 32
indicates that Selective Availability is enabled.

The Status Screens

SNRs appear only when satellites are being tracked. If a satellite is
visible but the receiver is not tracking it, it may appear with an
azimuth and elevation, but its SNR(s) will be blank. This is usually
because the satellite is below the user-specified elevation mask.

If an SNR value is followed by a ‘p’, the receiver is tracking P-code
on that frequency (L1 or L2) from that satellite. If an SNR value is
followed by an ‘x’, the receiver is doing cross-correlation processing
on that satellite's signals. In the 4000 SSi receivers, the SNR value is
followed by an ‘e’ indicating the P-code signal is encrypted and
Super-trak technology is being used to derive the L2 ranges.

A 3D position fix's maximum probable error, in meters, is
approximated by the product of the PDOP and the URA. As a rule of
