Trimble^® SiteVision^® is a real-time, in-field visualization software for collaborating on project progress and detecting design changes or conflicts. Use SiteVision to view 2D and 3D models in the context of the real world, and to document current conditions through georeferenced images and scans.  SiteVision supports a range of hardware configurations to enable collection of GNSS points, EDM points or LiDAR scans.

GNSS stands for “Global Navigation Satellite System”, which consists of a network of orbiting satellites, ground control stations, and user receivers that allow you to know your location in the world with the push of a button. GPS is the most commonly referenced GNSS constellation; others include GLONASS and Galileo. Refer to the Trimble Catalyst site for more information on the GNSS capabilities.

The SiteVision Integrated Positioning System (SIPS) is still supported, but not recommended as it has been superseded by the Trimble HPS2.  The DA2 Catalyst receiver included in the HPS2 offers far superior GNSS performance compared to the DA1 Catalyst antenna in the original SIPS handle.  Additionally the HPS2 offers support for both iOS and Android devices while the SIPS handle only supports Android.

SiteVision supports all global/regional GNSS systems. See the Trimble Catalyst Technologies site for a full list.  SiteVision shows the positioning solution used in the GNSS menu, accessible by selecting the satellite icon in the top-left corner.

The GNSS menu in the SiteVision app displays the type of positioning solution being used. The following positioning solutions are available: Autonomous, Differential, SBAS, HDRTK, and RTX.

The Trimble Catalyst service automatically selects and outputs the solution type with the best available accuracy by monitoring the accuracy that your system can achieve from the different signal types.

A network, such as Trimble VRS Now, broadcasts coordinates in relation to a global reference frame, like ITRF2014. This is referred to as a Source Reference Frame.

You might be using Trimble SiteVision with Trimble VRS Now, but want your coordinates in relation to a local reference frame which is commonly used for that region, such as NZGD2000. This is called the Target Reference Frame.

Within SiteVision you can specify the reference frame for your model (Target Reference Frame). The default reference frame used by Trimble Corrections Services is ITRF (International Terrestrial Reference Frame). The SiteVision application applies a real-time datum transformation from ITRF to the datum you have selected as your Target Reference Frame.

No. Your Trimble SiteVision subscription includes bundled access to Trimble VRS Now correction streams where it is available, and worldwide access to Trimble RTX technology.

However, if you are operating outside of a Trimble VRS Now coverage area, you will need a separate local VRS or IBSS delivered correction to achieve optimum results, which may incur additional costs.

Yes. Local correction sources such as a 3rd party and government VRS or IBSS networks can be used for the Trimble SiteVision System. To use a local correction source, you will need to deselect “Trimble Corrections Hub” and enter the required information under GNSS Configuration within the Trimble SiteVision application.

Trimble Corrections Hub (TCH) is a service that provides high-accuracy GNSS corrections. TCH automatically selects the best available correction source based on your location and internet availability. TCH includes access to Trimble VRSNow, Trimble RTX via IP, and Trimble RTX via satellite corrections, and is included with SiteVision Pro licenses.

Yes. In addition to being compatible with TCH, Trimble SiteVision also supports local corrections though third party VRS networks, or through IBSS (Internet Base Station Service).

In SiteVision there are five ways to position a model on site: Automatic, Measured, Manual, Marker, and Component.  

• Automatic Placement requires high accuracy GNSS and a defined coordinate system. 

  • The Trimble DA2 or HPS2 handle provides GNSS positions when working outdoors

  • The coordinate system can be defined in two different ways. The simplest way is to assign the published coordinate reference system (CRS) within Trimble Connect for the whole project. Alternatively, you can use a local site calibration file.

  • Automatic placements will apply to all future sessions unless they are overwritten by a new calibration.

• Measured Placement requires high accuracy GNSS, and walks you through steps for completing your own two point calibration to position a model. This information is recorded and remembered for the next time you open the model to view with SiteVision.

• Manual Placement is done using gestures on the screen and the augmented reality technology on your field device. This method does not require GNSS and so it can be used indoors, but as a result, model drift may occur. Any manually placed models will only be valid for that specific SiteVision session.

• Marker Placement uses a printed QR Marker that is linked to a location in the model. This method does not require GNSS and so it can be used indoors. This method is helpful when you want to return to the same model and location without doing a manual placement each time.

• Component Placement is specifically designed for fabrication workflows and allows a specific part to be isolated within a larger model.  The model can then be aligned by either scanning a QR Marker or by manually picking 3 points within both the model and real world. 

The accuracy of Trimble SiteVision depends on several factors, including whether you are using GNSS, and the model placement method. 

• GNSS positioning accuracy is determined by your GNSS hardware (Trimble DA2 or HPS2) as well as your correction source (VRSNow, RTX via IP, RTX via satellite, a local VRS network, or a local base broadcasting over IBSS).

• Model placement accuracy is dependent on which method you chose, your initial calibration, and if you’re working indoors, how far you move from where the model was initially placed (model drift).

If you are using GNSS, and have good VRSNow coverage, your positions, collected data, and the display of your 3D models can be as accurate as 1-2 cm (0.4 - 0.8 in).

You must have an internet connection to download models from Trimble Connect, and to obtain the best possible GNSS positions (1-2cm precision). You can operate SiteVision without an internet connection but with the following limitations:

• You must have logged into SiteVision on the device previously, when you had an internet connection

• To use a model from Trimble Connect, you must have already downloaded your model while connected to the internet.

• GNSS positioning may not be as accurate, as you will be operating with the satellite-delivered Trimble RTX correction stream or a local SBAS service.
