2 Tripod Set Up Procedure

2.1 For Tribrach with Non-rotating Optical Plummets

a. Extend tripod legs so the top of the tripod head comes up to your chin. Lock legs at this height

with the leg screws. If the ground is not level the legs will have to be extended at different
lengths.

b. Attach tribrach to tripod head using the large center screw on the tripod head. Make sure that

the leveling foot screws on the tribrach are centered half way between their range of move­ment.

c. Open tripod legs over the mark and step (set) one leg into the ground at about a 45o slant angle

and about 3 feet from the station mark. Look through the optical plummet and position the cross
hairs over the point using the remaining two tripod legs. If viewing or crosshairs are out of focus
adjust the crosshairs ring first until the crosshairs appear clear and crisp. Adjust the focus ring
until the image is in focus. To check for parallax slowly move your head around while looking
through the optical plummet. You should see no movement between the crosshairs and the
focused background (this is known as being out of parallax), nor should the crosshairs move
apart.

d. Once the cross hairs are within 1 cm of the point and the head of the tripod is visually level,

step the remaining two legs into the ground. At this point sand bag or tie down the tripod legs.

e. Precisely position the tribrach crosshairs over the point using the leveling foot screws on the

tribrach.

f. Level the bull’s-eye bubble on the tribrach by using two tripod legs. (Do not level using the tri-

brach foot screws.) At this point you are leveling the tripod head.

g. When the bubble is within the circle of the bull’s eye use the tribrach leveling foot screws to

precisely center the bubble.

h. Once the bull’s-eye bubble is precisely level, look through the optical plummet to ensure that

the crosshairs are over the point or at least within a few cms. Center the crosshairs precisely
over the point by loosening the tripod head screw and gently slide the tribrach over the point.
When centered tighten the tripod head screw.

i. Check the level bubble. If the level is outl:

♦ just a little - repeat steps g & h.
♦ by a lot - (more than a couple of mms) - repeat steps e,f,g,h.

j. Check the set up and calibration of the tribrach by attaching the plumb bob to the tribrach head

screw so it hangs over the point. It should hang precisely over the point +/- the plumb bob string
width. NOTE: This will not necessarily be true in windy conditions. In windy conditions the
plumb bob will be blown away from the mark. If the site is located in an area with high winds
the calibration of the tribrach can be checked indoors by performing the set up procedure.

July, 1995

2.2 For Tribrach with Rotating Optical Plummet

a. Proceed with steps 2-1(a-i).
b. Turn the tribrach so that the plate bubble tube is parallel to two footscrews. Center the bubble

by adjusting these two footscrews in equal and opposite directions.

c. Turn the tribrach through 90 degrees. Center the bubble with the third footscrew.
d. Turn the tribrach through 90 degrees so that the bubble is parallel to the first 2 footscrews. Note

position of bubble. If the bubble is centered between the middle divisions, then the tribrach is

5

level in this plane. If the bubble sits more than one division off center, then note how many
divisions off center it lies and by adjusting the two footscrews in equal and opposite directions
bring the bubble toward the center by half the amount it was off center before. Turn the tribrach
through 180 degrees again and check where the bubble rests. Repeat the process until the
bubble is within one division of the central division.

e. Now turn the tribrach through 90 degrees and check the level in this plane. Note the position

of the bubble. If the bubble is off center by more than one division, turn the third footscrew to
bring the bubble to a point halfway between the position noted and the centered position.
Rotate through 180 degrees and check again using the third footscrew for any fine adjustment.

f. Now rotate the tribrach through 360 degrees and check if the bubble remains within 1 division

of the center for any position.

g. Center the adapter precisely over the point by loosening the tripod head screw and gently slid-

ing the tribrach over the point. When centered tighten the tripod head screw.

h. Check the set up and calibration of the tribrach by rotating the adapter 180 degrees and check

the plummet. If the tribrach is off center by more then 1mm then loosen the tripod head screw
and gently slide the tribrach half the distance it was off. Rotate the adapter 180 degrees and
recheck the plumb. The offset should be the same. If not repeat this step again.

3 Trimble 4000 SSE Equipment

Configuration for GPS Surveys

3.1 Power Requirements

The Trimble 4000SSE Receiver operates between 10.5 dc volts (Vdc) and 35 Vdc. The receiver will
automatically shut off if the voltage drops below 10.5 Vdc and it will not turn on if the power is less
than 11.5Vdc.

The receiver draws 9 watts of power. A fully charged 12V battery with a 10 amp hour(Ah) rating will
theoretically power the receiver for about 13 hours(10Ah / 9W X 12V). However, the amount of time
a battery can power the receiver can be misleading since the actual length decreases depending
on the operating temperature and the number of charging cycles the battery has gone through.

All UNA VCO’ s 12V gel cell batteries are tested to last at least 8 hrs at room temperature when fully
charged.

Many different power configurations for 4000SSE receiver exist. Two common configurations are
shown in figures 3-1 and 3-2. The power configuration shown in Figure 3-1 has two gel cell batteries
powering the receiver. This power configuration should be used for observation periods less then
15 hours. The configuration shown in Figure 3-2 is recommended if the receiver is to be used con­tinuously for several days. In this configuration, two batteries and a set of solar panels are used.
Depending on available sunlight, the battery attached to the solar panels may sustain the receiver
for a week or more.

July, 1995

3.2 Preparing for a GPS Survey

3.2.1 Antenna set-up

a. Set the tripod over the mark. (refer to Chapter 2) Attach the antenna to the tribrach adapter.

Carefully slide the tribrach adapter into the tribrach, being careful not to disturb the tripod.

b. Carefully unroll the antenna cable.
c. Connect the antenna cable to the threaded connection on the antenna housing. Be careful not

to cross-thread the connection.

d. Connect the antenna cable to the antenna port on the receiver.
e. Orientate the antenna to true north and secure in place.
f. Secure the dangling antenna cable to the tripod so that it won’t blow in the wind.
g. Recheck the level and the centering of the antenna.

3.2.2 Power Configurations for the Trimble 4000SSE

a. Short-term Occupations (refer to figure 3-1)

1. Connect the two gel cell batteries to the two power ports.

♦

Note: The LIMO connection on the battery cable has a red dot. Line this red dot up
with the red mark on the power port.

b. Long-term Occupations (refer to figure 3-2)

1. Main Battery. Using the auxiliary battery cable, attach the car battery to power PWR 2/

3 port. Ensure the connections to the battery are correct. The positive (+) terminal is red or
white and the negative (-) is black.

7

2. Backup Battery. Connect the 12V gel cell battery to the PWR I/O 1 port on the back of

the receiver.

3. Solar Panels.

♦ Attach the solar panel regulator to the solar panels. Place the regulator in a plastic

bag. Fold close the solar panels. Connect the alligator clips to appropriate terminals
on the main battery.

♦ Open the solar panels one panel at time. This avoids creating a power surge. Place

the panels in the sun in perpendicular to the sun’s rays. Ensure the panels are placed
in an area that has maximum sunlight over the course of the day.

4 The Trimble 4000SSE Control

Parameters (ver 6.12)

For Trimble Receivers with V6.12 Nav Software

This guide indicates the receiver’s default settings to be used for normal surveys. This guide does not
cover pre-programming the Trimble receiver. The instructions are not intended as a substitute for the

Trimble 4000SSE Operation Manual

programmed.

The Trimble 4000SSE GPS receiver operates between 10.5 & 35 VDC 9 watts nominal power. One 12V
(~12 Ah) sealed dry cell battery will provide about 8 hours of operating time when in good condition and
fully charged. The system will simultaneously track up to 9 satellites in both L1 and L2 and can store
almost 224 hours of survey data (8 SVs at a 30 seconds collection interval) on its 5-Mbyte RAM memory.
The following are ground rules for the use of UNAVCO equipment:

a. At all times, UNAVCO equipment must be operated from a covered area (such as inside a car,

tent, or building).

b. UNAVCO equipment must never be transported outside of their cases.
c. Never leave the equipment unattended. The operator is held responsible for data acquisition

and safekeeping of equipment in their care.

d. Never attempt to modify nor repair any piece of UNAVCO equipment. If you break something,

call the UNAVCO project engineer immediately.

. Consult the project engineer if your receiver is to be pre-

The following is a list of the receiver default settings. These defaults should not be changed unless
instructed by the project Engineer.

When the power key is pressed, the 4000SSE system will first go through a number of self tests.

4.1 The Receiver’s Control Parameters

The Trimble 4000 SSE Front Display and Back Panel (fig. 3-3) the front view of the Trimble 4000SSE
display panel. Control inputs are accessed via the CONTROL key. The control parameters, with the
exception of deleting old data files, do not need to be changed each time the receiver is turned on. The
control parameters are preset at UNAVCO and should not be changed unless instructed by the field
engineer.

The following is a list of the receiver’s control parameters and a brief description of what they are used for.
At any point in the CONTROL menu the CLEAR key can be pressed one or more times to exit.

NOTE: Not all receivers will have all the options listed below. Some may have more too.

4.1.1 Logged Data Files

This control parameter allows you to check the receiver’s memory for stored files. In this menu, files can be
deleted or recovered.

12

July,1995

♦ Deleting Data Files

To delete files press the DELETE key. When the key is pressed the following screen will appear with the
data files from previous surveys.

SIZE OF FILE

To delete the file shown press the DELETE IT key. To delete other files in the receiver’s memory press the
NEXT FILE key until the desired file is displayed. To clear the receiver ’s memory press DELETE IT until
“FILE DIRECTORY IS EMPTY” is displayed. Press the CONTROL key to return to the main menu.

Deleting the files leaves a full block of memory for observations. When a file is deleted it can still be
recovered only if no other data has been written to the memory.

♦ Recovering Data Files

DELETE IT

If you need to recover previously deleted files, follow the same procedure as above but select RECOVER
instead of DELETE. Then select the data file to recover by pressing the NEXT FILE key until the desired
file is displayed: Once the desired file to recover is displayed press the RECOVER IT key.

4.1.2 RTCM-104 Controls

The option for RTCM-104 INPUTS and PORT SELECT should be off. This option allows the receiver to
compare previously stored coordinates with computed values from GPS measurements. The receiver can
then send out corrections to remote receivers via a communications system. An example of the use of this
option would be for navigating. For example, a receiver could be placed at a known base station at the
entrance of a harbor and then send out GPS corrections to incoming ships.

4.1.3 Power-up Mode

This option should be set to DEFAULT OF CONTROLS. This option is used in conjunction with the RTCM
option and other navigation options. It sets the receiver to default to certain parameters when power is lost
and then restored.

4.1.4 SV Enable/Disable

Each SV can be tracked in one of four modes, IGNORE HEALTH (SURVEYING), DISABLED, ENABLED,
and IGNORE HEAL TH (POSITIONING) . A satellite can be either listed healthy or unhealthy. The health of

a particular satellite can be changed without warning by the U.S. Government for a variety of reasons. No

1. NOTE: Only files that have been downloaded should be deleted.

13

July,1995

SVs should be DISABLED. For most GPS surveys IGNORE HEALTH (SURVEYING) will be used. To
check that all SVs are IGNORE HEALTH (SURVEYING) press the MORE MODES key. Under the

IGNORE HEALTH (SURVEYING) menu all the satellite numbers should be listed. If any option other than
IGNORE HEAL TH (SURVEYING) had SVs listed check with the project engineer to be sure this is correct.

The differences between the settings are:

♦ IGNORE HEALTH (SURVEYING): Receiver will attempt to log data fram a satellite

regardless of its health. The data can then be evaluated during post-processing.

♦ DISABLED: Receiver will not tract a specified satellite.
♦ ENABLED: Receiver will only track a satellite if it is healthy.
♦ IGNORE HEALTH (POSITION): Receiver will attempt to track satellite regardless of

health. This option is used in conjunction with navigation purposes. Only psuedo-range data
will be collecected.

4.1.5 Adjust Local Time

The TIME OFFSET (UTC-UTC) should be 0:00 and the TIME ZONE IDENTIFIER = UTC. For all surveys
the local time is UTC. This eliminates any time errors that could occur due to time zone differences within
the project area.

4.1.6 Baud Rate /Format

The settings for PORT 1 should be BAUD RATE: 9600 and FORMAT: 8 ODD 1. PORT 2 should be the
same. This option is used to control the communications between the receiver and any external device at­tached to it (e.g. a download computer).

4.1.7 Remote Protocol

This options is used in conjunction with external devices (i.e. a datalogger) and for making firmware up­dates. This option is not used for UNAVCO GPS surveys.

4.1.8 Reference Position

The default value is all zeros. The receiver uses an “anywhere fix” operation and does not need to know
where it is to start a survey.

4.1.9 Masks/Sync Time

This option allows you to change the elevation mask and sync time while a survey is in progress, however,
these values are entered into the receiver when the receiver is programmed for a specific survey.

4.1.10 Positioning Mode

The receiver can be set to determine it’s position using several different options.

♦ latitude, longitude, and height or latitude/ longitude (depends on # of satellites)
♦ latitude/ longitude (fixed height)
♦ height (fixed latitude/ longitude)
♦ latitude, longitude, and height always (depends on # of satellites)

The determined position can either have a weighted solution or not. The positioning mode is used mostly
for navigation purposes. For UNAVCO GPS surveying purposes all data is stored and then analyzed later.
The real time position is not used.

14

July,1995

4.1.11Power Control

This option is set to off. This option allows for the receivers internal battery charger to be turned on or to
power external devices plugged into the ports. The option can only be used if a Trimble Office Support
Module (OSM) is powering the receiver.

4.1.12 L1/L2 Operations

All 9 channels are configured to collect both L1 P (P-code) and L2P (P-code) data. During times of Anti­Spoofing (AS) the receiver will automatically switch to cross-correlation tracking mode (L1P and L2x).

4.1.13 NMEA-183 Outputs

All options should be set to off. NMEA-183 (National Maritime Electronic Association) is used for
navigation purposes. This option allows the receiver to output six different navigation parameters to aid
with other navigational sensors.

4.1.14 Cycle Printouts

This is a printer output option used for navigation purposes and is not needed for UNAVCO supported
surveys, therefor, ENABLE is OFF.

4.1.15 PPS Output and Time Tag

This option is a time strobe and its associated time tag. The 1PPS OUTPUT is [DISABLED], the SLOPE is
NEGATIVE and the ASCII TIME TAGS are set to [NONE].

4.1.16 Event Markers

This option is used to provide a precise GPS time tag for an externally generated pulse, i.e. a photogram­metric camera. This is option is always DISABLED.

4.1.17 Default Control Parameters

This option is used to set the receiver to a factory default condition. It should not be used unless instructed
by the field engineer.

6-7 Renaming files

If files were named incorrectly or if the receiver is programmed to use auto-survey mode1 (all files will have
the same name) it will be necessary to rename the files before continuing the downloading process. To
determine the correct name for each file look at the date of the file. The date will be the same as the date
the session started. For example:

Session Size Date Time

AAFB-084-0 5678 Mar 24 94 06:29

>

AAFB-084-0 5479 Mar 25 94 06:29
AAFB-084-0 1368 Mar 26 94 06:29

In this example the first survey was started on March 24 1994, which is julian day 084. All sessions that
follow have the same name, AAFB-084-0, even though they started on days 085 and 086. The new names
should contain the julian day that the survey was started.

a. To rename a file

♦ Select the file you want to rename using the arrow keys.
♦ Choose option F4 - Rename File by pressing the <F4> key.
♦ Rename the file (e.g. change the -084 to -085), then press <Enter>. The file will be

renamed and will appear on the screen as:

Session Size Date Time

AAFB-084-0 5678 Mar 24 94 06:29

AAFB-085-0 5479 Mar 25 94 06:29

AAFB-084-0 1368 Mar 26 94 06:29

Once the files are correctly named continue with the next step.

6-8 Selecting a Data File to Download

a. Use the arrow keys and space bar to select the files for downloading. If there were no problems

during tracking and you are deleting files after each download, there should be only one data
file. A selected file will be highlighted.

b. Press the <F10> key to initiate the download process. The computer will prompt you to ensure

that there is enough room on the drive where the data will be written. You will be prompted to

You will need to copy the files from the computer’s hard drive to the floppy disks.

a. Using the Help Menu

1. If you download files while the receiver is in a session, it will not lose lock on the satellites, however, it will stop logging data
during the duration of the download. If you download during a session you the file that the data is written being written to can be
downloaded. This file is incomplete as data will continue to be recorded to it until the end of the session.

♦ At anytime in the “Backup Menus” you can enter the help window by pressing the

<F1> key. The help menu gives a brief explanation of the options used to backup the

data.

b. Backup Current Menu

♦ Once the data has been successfully downloaded to the computers’ harddrive you

can then copy theses files to floppy disks. Choose the option:Backup Current
Menu. The computer screen will show a listing of all the data files you have just

downloaded from the receiver.

♦ To select a file to transfer to the floppy, use the arrow keys to highlight the desired

file. Then press “T”: for tag. Press “U” to untag the highlighted file.

♦ Once the desired file(s) is tagged press “C” to copy. The computer will prompt you to

“Put a NEW formatted data diskette in drive “A”. Press any key when ready.”

files. When copying is complete the computer will indicate it and ask you to press any
key to continue.

♦ When the computer returns to the data list menu a “#” will appear next to the file you

just copied. If a “φ” appears next to the file an error has occurred. This is the result of

either a bad data copy or the disk was not a new one. Retry the transfer with a new
disk. When transfer is complete, eject the disk and fill out a label. Label this disk “A
Copy”.

♦ Most UNAVCO GPS projects require two copies of the files on diskettes. Make

another copy and label it “B copy”.

♦ Once the files have been successfully downloaded to the floppies they will no longer

be listed in this menu once you exit the program. The files will still be stored on the
computer’s hard drive but they will not be accessible. Ensure you have made all the
necessary copies before exiting the program.

c. Backup Later Menu

♦ If files cannot be transferred to floppy disk immediately after downloading they can

be transferred at a later time. When the computer is turned off the files will be placed
in the “Backup Later” menu. Files can then be selected and transferred just as
described above in the “Backup Current Menu”.

♦ Once the files have be successfully downloaded to the floppies they will no longer be

listed once you exit the program
