GS8000 uses SFCW (Stepped-Frequency Continuous Wave) GPR technology, which modulates a wide range of radar frequencies at once. Therefore, at the same time, you can expect the penetration depth and performance of a traditional GPR cart for utility locating, and the ultra-high resolution of a handheld GPR for concrete in the first 1 to 1.5 meters, unique in the industry.

GS8000 includes a survey-grade GNSS receiver to provide centimetric precision in real time if standard conditions are met: at least 5 satellites are visible in the sky and your iPad is connected to Internet. In Europe & USA, the GS8000 can connect to the revolutionary SSR augmentation service and get 3-6 cm precision out of the box. Elsewhere, a 2-3 cm precision level can also be achieved by entering the NTRIP details of a nearby RTK server or base station, if available.

In GNSS-denied areas, it is also possible to use third party terrestrial positioning systems. To do so, all that is needed is to connect the field controller of a robotic total station to the GS8000 and stream continuous positions. To achieve so, Proceq offers a cable with a DB-9 (RS232) ending where most third party controllers can be connected – with or without an intermediate serial cable or adapter - and output Pseudo NMEA GGA sentences, understandable by the GS8000.

Alternatively, GS8000 can also be used as a traditional GPR device, without any positioning.

The revolutionary Free Path data collection method allows to scan with your GS8000 on a freeform area and see the resulting heatmap of the subsurface plotted on a map in real time, at the desired depth range. This has an enormous impact in reducing guesswork on site, as opposed to the traditional method of marking findings on the ground with spray and trying to figure out how they align to each other, or time-consuming grid scanning.

With Free Path, it is possible to see a service line literally forming in front of your eyes as you move to make decisions while scanning. Moreover, any features above the surface or found with complementary techniques can be digitized on the same map, thus, providing a comprehensive view of the area while on site, without any need to process and merge data.

When collecting data in Free Path mode, all digital findings and linework on the map can be directly output to CAD and GIS platforms, which rely on the data to be geo-referenced in the right coordinate system. Therefore,...

When collecting data in Free Path mode, all digital findings and linework on the map can be directly output to CAD and GIS platforms, which rely on the data to be geo-referenced in the right coordinate system. Therefore, GS8000 comes pre-loaded with official EPSG regional and state level coordinate systems used by most popular GIS systems, as defined by the Geomatics Committee of the International Association of Oil & Gas.

When you set up the GS8000 to work on a particular coordinate system, the coordinates of every scan or digitized feature are transformed to it, and effectively applied to the different CAD and GIS outputs. This reduces the need to involve CAD technicians in merging and transform field data in the office, which is a common source of error and inefficiency.

There are multiple types of annotations available:

• Tags, which are categorized points input on the radargram at a certain depth
• Points of interest, which are categorized points surveyed on the ground
• Markers, which are uncategorized points input on the radargram or surveyed on the ground, and can contain comments or voice notes
• Linework, which are categorized lines connecting tags, points of interest, markers or any other point at a certain depth

All these elements can be output to CAD / GIS formats in the corresponding layers and positions.

Additionally, it is possible to add photos manually sketch / draw on top of the image or take screenshots and include them in the reports alongside the annotation types above.

The 3D accuracy of the coordinates of a tag depends on 3 main factors:

• How precisely the dielectric constant was calibrated, as this determines the translation between signal velocity to the distance travelled by the radar wave; otherwise said, the correctness of the calculated depth
• How precise the GNSS position quality was when the measurement happened, as this determines how reliable the calculated 2D position and ground zero value are
• If the set coordinate system is the expected one, as this will make the digital finding match the existing cartography or not, no matter how precisely it was measured.

Considering all non-human sources of error combined, Proceq GS8000 can provide reliable 3D results on a sub-decimeter range under standard conditions.

Yes. The traditional view on GPR data, that is, a full screen view of the B-scan, is always available with a simple two-finger swipe on the screen. It is also possible to run the GS8000 without absolute positioning, by simply not connecting the GNSS receiver to it.

It is also possible to scan on a predefined grid, following any order and scan pattern.

The recommended controllers are the latest models of iPad Pro WiFi + Cellular (with M1 processor) to ensure the best connectivity and processing power in the market, crucial for moving big amounts of data with ease. Any size of iPad Pro can be mounted on the GS8000 handle using the supplied tablet holder. A protective case is recommended. Under extreme temperatures, a compatible cooling case such as x-Naut is the best choice.

The latest version of the app will work on the current major iOS version in the market, plus the two previous ones. There is no need to pair a specific iPad to the GS8000: any iPad will be able to run the app and control your GS8000, as long as it is running a valid subscription contract.

GS8000 can hold simultaneously a set of rechargeable batteries (8x C-Type NiMH) and a commercially available power bank (of the type described in the Power Bank Compatibility Chart) – or two of the same type. They are hot-swappable, and therefore, easily allow for a full day of continuous work.

If Internet is available, the data start synchronizing to the cloud automatically. The time needed to complete the process depends on the mobile network and amount of collected data but is generally very fast. Once synchronized, the field data, reports and CAD/GIS deliverables can be shared with anybody over chat, email, etc. or accessed via web, anywhere, anytime.

The GS app includes a Mobile Data Saving setting to prevent the automatic synchronization when using mobile networks; in that case, the synchronization will happen as soon as the iPad connects to a WiFi network.
