Page 7: Introduction
1 Introduction The GS9000 is a high-productivity GPR mapping system in the form of pushcart for manual operation. It is based on multichannel stepped frequency GPR technology patented by Proceq. The product consists of An iOS field app (GS) running on any iPad Pro tablet ¡...
Page 8: Scope Of This Document
1.1 Scope of this document This document is aimed to assist the user of GS9000 in the setup and operation of the system for productive use. To achieve so, a sequence of basic steps is suggested, alongside possible alternative steps, when suitable.
Page 9: Main Applications
Post-processing GPR Insights on web GPR Insights on local machine 1.3 Main applications The GS9000 sensor can be used for various applications, depending on the type of GPR module attached : High-frequency GPR applications ¡ These applications are attainable when the GS9000 is connected to the GX1 array.
Page 10 When the GPR system is used standalone without any geopositioning module, every scan point has a relative position to the scanned line, but not absolute. This is the default operation mode of GS9000 Lite, and applications focusing on immediate results on-site, such as damage prevention before digging, do typically not need any further action.

3.2 GNSS positioning GS9000 can accommodate a GNSS receiver (MA8000) developed by Proceq, with internet- based SSR corrections included. Alternatively, the GNSS receiver can receive NTRIP real- time corrections from a 3 party server, provided the right credentials are available.
Page 13 Figure 4 : Schema of differential GNSS corrections & current coverage of SSR service provided by Proceq The current coverage of SSR corrections includes: continental Europe, USA, Canada (trans-canadian corridor), South Korea, southeastern and southwestern Australia. The achieved accuracy is subject to the number of visible satellites and their geometry in the sky, atmospheric conditions, observation time, etc.

Page 17: Connecting The Gpr Multichannel Array Module
1. Place the GX1 or GX2 array module in front of the GS9000 pushcart, with the antenna connector (1) facing back and the straps released (2) 2. Lift the front (3) of the GS9000 and move it forward until it gently sits on top of and perfectly aligned with the GX array module.
Page 18: Adjusting The Straps
GX array module. 4.3.3 Connecting the antenna cable The electronics of the GS9000 and the GX array module are connected with an antenna cable. 1. Make sure the cable is facing the correct polarity of the connector (1) on both ends 2.
Page 19: Attaching The Gnss Receiver
Optionally, a tripod can be installed to make the position of the pole solidary to the GS9000: 4. Pass one of the hitch pins through the both holes on the GS9000 rear corner and at the end of the tripod leg (4) 5.
Page 20: Powering Concept
2. Accommodate the power bank to with the foam and close. Repeat for 2 power bank. 3. It is not necessary to turn the power bank on – the GS9000 will turn it on automatically. Figure 15: Open power bank drawer Make sure the USB-C cable is disconnected from the power bank if left inside the drawer overnight.
Page 22: Optional Wired Connections
Typically, when there are WiFi restrictions on the job site – or when a WiFi hotspot is used as source of mobile data for the iPad – it is possible to connect the iPad Pro to the GS9000 via a USB cable supplied with the system.
Page 23: General Maintenance Tips
This cable needs to be connected to both Lemo connectors, on the GS9000 and the MA8000. 4.8 General maintenance tips The standard delivery of GS9000 includes a small toolbox to self-perform the basic maintenance of the equipment: 4.8.1 Replacing the skid plate To replace a worn-out skid plate for a new one on either GX1 or GX2 modules, the lateral screws need to be unscrewed first with the tool provided in the toolkit.
Page 24: Replacing Wheels
– see chapter 5.5.1 Calibrating the odometer 4.8.3 Cleaning the system After usage, it is recommended to clean the GS9000 from dirty elements such as dust and mud, if present. Please take the following precautions before cleaning: Avoid high pressurized water and long-time direct water hosing onto the device.
Page 25 The pedal can be engaged or disengaged with a simple push down or pull up gesture made with the foot. Figure 21 : Engaging the wheel blocking pedal When the device is not in use, the parking brake should be engaged. 5. July 2024 © Copyright 2024, PROCEQ SA...
Page 26: Connecting The App To The Sensors
5 Connecting the app to the sensors The GS9000 system is controlled by an iOS app which can run on an iPad Pro. To efficiently calculate and manage the big volumes of data the GS9000 system can collect, as well as getting the right connectivity level to enjoy the services around it, it is strongly recommended to opt for an iPad Pro®...

On the first use, the first step is to log in with the user credentials – which have been previously created in Workspace. In case of difficulties to generate a Screening Eagle ID, please contact your local Proceq office or authorized dealer.
Page 28: Registering The Equipment
Please note that the iPad Pro needs Internet access to complete this initial step, either using mobile data from integrated SIM card or access to a hotspot via WiFi. To do so, first the GS9000 needs to be registered: 1. Go to the Probe tile.
Page 29: Connecting To The Gs9000
Figure 25: Connecting the app to the GS9000 sensor In case of multiple unsuccessful attempts to connect, it is recommended to restart both the GS9000 (with a hard button press) and the app (with a swipe out screen to force the closure of the app).
Page 30: Calibrating The Odometer
1. In the Position menu, press the button left of the desired serial number in the list. 2. If GS9000 is connected to the MA8000 via cable, it will connect automatically. 3. If they are not physically wired, a Bluetooth connection will be established between iPad Pro and MA8000 within approx.
Page 31: Setting Up The Gnss Correction Service
(e.g. a mobile phone) via WiFi. In the latter case, the connection between iPad Pro and GS9000 needs to be via cable to free up the WiFi connection for the hotspot. To set up the correction service, the MA8000 needs to be previously connected to the app.
