(How To) GPS 2023

Check list

0.This is the start of preparing GPS Equipment to send out for work (Modules 1-6)
1.Grab a Machine control set as well as a Base/Rover set
2.Set up the GPS Base & Rover on a known control point
3.Ensure the piece of equipment which the GPS is on has all the attachments and posts in there correct working order
4.Set up the Machine control on your selected piece of equipment
5.Make sure the connection between both the Machine Control & GPS Base/Rover is consistent as well as Functional
6.Preform a final check by going through 3 connectivity tests which include the, TDL450, Pods, & Screen
This is the end of the GPS & Survey Guide

Part 1

If you are having troubles locating the necessary equipment, ask a GPS Manager to assist you in collecting all the GPS gear needed

Base & Rover Set
1x Base
1x Rover
2x Antennas
1x Tape Measure
1x Tripod
1x Tribrach (Including mounting Bracket)
1x Data Collector
3x Charged Batteries
1x Rover Pole
Machine Control Set
2x Matching Pods (MC All)
1x CB460 Screen

4x Coily cables

Make sure to ask GPS services if you need help adding files to equipment

Data Files (USB Stick) “Ask GPS Services”
Machine Control Data- Folder (Surface- SVD, Line Strings- SVL, Coordinate system- Cal)
Data Collector Files- DXF, CSV, TTM

Part 2

Locate an existing Control point and begin to Set up the GPS Base

Setting Up GPS Base Station
Grab all the GPS Base & Rover Gear
Set up Tripod directly over the Pin (The longer the legs are extended the easier it will be to level)
Once you’re happy with the Tripods positioning, grab the Tribrach and attach it to the Top of the Tripod
There is a small eye piece on the Tribrach along with some dales, Use those dales to center the bullseye like symbol you see when peering into the eyepiece, directly on the middle of the pin (You may need to use an object to guide your eyes to the pins location)
Once the bullseye is centered use the adjustable legs located on the Tripod to level the entire setup (The level is located on the Tribrach)
When everything is level, place the mounting bracket which came with the Tribrach onto the bottom of the GPS Base
Attach an Antenna to the GPS Base
Attach the GPS Base to the Tripod set up & make sure everything is still level
Retrieve the Data Collecter & turn it on
Connecting to the Base *Do before setting up the Rover   “Enter Project setup ” Select Connect device – GNNS Select Base- Bluetooth *Connect to the proper base device Correction Method – Radio & Receiver 1 Base 0 Repeaters Radio wireless mode – TT450S @9600 Radio Channel – 4:440.500 Base Position – Control Point Control Point – Select the point that lines up with your Bases position Antenna – Select the appropriate model based on what is attached to the Base being used Antenna Height – Measure from the top of the “Pinhead” to the (Bottom Notch) of the Satellite connected to the Base Elevation Mask – 10 Corrections – RTCM 3.0x * Could change depending on the base Base Station ID – Use the appropriate ID
Once the GPS Base has been setup, move on to the GPS Rover
Connecting to the Rover *Do after Base has been connected & fully setup   Connect the Rover to the Topo Pole Add an Antenna to the Rover and Turn it on “Enter Project set up” Select Connect Device – GNNS Select Rover – Bluetooth *Connect the Proper rover device – via Serial Number Correction Method – Radio & Receiver Radio wireless mode – TT450S @9600 Radio Channel – 4:440.500 *Make sure Channel matches the Base Connected to Base – RTCM0031 * This Could be different depending on the model of your base
This is the end of setting up the GPS Base & Rover

Part 3

 Head over to the Construction Shop to begin setting up the chosen piece of machinery with GPS

(Each piece of GPS Equipment- Excavators, Scrappers, Dozers, & Graders have there own unique setups)

GPS Machine Control Setup (Dozer)
Posts are straight and cable hangers point to the right.
Posts are steel (may need Danny to build some)
Screen isn’t floppy (may need new latch or foam between brackets)
The Pods fit snug on the posts
Coily Cables can fit properly in their hangers
Both power and radio cables are undamaged and functional for the TDL450

Part 4

Trimble Machine Control can be setup in the same manner on each piece of GPS plumbed machinery

Setting up GPS Machine Control
Put the Pods on the posts, with the power panels facing the heavy-duty Machinery’s cab
Connect the coily cables to the designated power ports on the heavy-duty machine (Make sure the safety pins are attached to the cable hangers)
Enter the cab and attach the TDL450 to the side of the machines cab, connecting power to the bottom & Radio to the top (The TDL450 should automatically come on, but if not hit the power button)
Place the CB460 screen into its designated holder and connect the power cable (Make sure the screen is tight and will not wobble around, as that will ware it out and wreck the finishing)

Part 5

This process is based on the correct setup of both the GPS Base & Rover- If the settings are not the same as what’s listed in Step 2, nothing will work

Ensure the TDL450 settings match what the GPS Base was setup as
Check Baud Rate
Check Radio Channel
Check Radio wireless mode
If everything was done correctly, a green blinking light will appear on the TDL450 Radio
Ensure the CB460 screen settings match what the GPS base was setup as
To perform these checks, you’ll need to be in managers mode- Press and hold the ok button and then select the power button, let go of the power button, but continue to hold the ok button for 15 seconds
Once the screen has booted up, insert the Machine Control USB stick
Select Add from USB & remove the USB
Select the 3 lines on the right side of the screen and use the down arrow until you find Restore Machine Settings
Find the machine you’re using and select that file
Hit the return button and find your way back to the top of the main menu
There is an option to select a design, add the most recent one (This is the design that was located on the USB Drive)
Once this is finished you can move onto the final GPS Base to Machine control test: Select the 3 lines on the right side of the screen    When the menu is open select the installation option on the right-hand side of said menu Locate the Connectivity Settings, then Control Box Radio Port drop down and change the baud rate to match what the TDL450 is set to    If there is still no communication, try changing the “COM Port” on that same screen
In some cases, the Left & Right Pods will not communicate, this can be checked in the GNNS page To get to the GNNS page find your way to the main menu of the CB460 and Select diagnostics click the bottom right icon that looks like a Satellite. Select GNSS diagnostics & change between Left and right pod using the button which is on the Top side of the CB460.
If one or both pods having no satellite’s, G1, or L1: Try changing Coily Cables Check Can Rate- Main Menu, scroll to the bottom, GNSS receiver Configuration- Top Right button- Can1 or Can 0 Check the Wiring where the Coily Cables hooks to the Dozer or other plumbed in piece of Equipment If none of these fix the problem- Call GPS Services
Once all those setting are change and or updated you can move to the last part

Part 6

The final part is running through various settings to ensure everything is communicating properly

Make your way over to the TDL 450
Check to see if the TDL450 is on
Check if there is a Flashing Green RTX Light, if so the TDL450 is working
Make your way to the main menu of the CB460 screen
Select diagnostics- Check if all connections are working
Select GNSS diagnostics- Check if all the boxes have numbers for both the left & right pod
Check if there are Flashing light on either side of the CB460
Return to the home screen & check to see if there is a machine on the screen
If all these checks were confirmed the piece of equipment is ready to go, if not Call GPS Services
