Trimble introduced the TSC2 Controller, an advanced handheld field computer designed for integrated surveying solutions using both GPS and optical total stations. Equipped with Microsoft Windows Mobile software for the Pocket PC operating system, the TSC2 Controller will run the user's choice of Trimble field software. Users can also add specialized Pocket PC applications to the standard Microsoft Pocket Messaging (Outlook), Internet Explorer, Word and Excel applications. The TSC2 Controller works in conjunction with Trimble GPS survey systems and Trimble total stations. With the use of field software such as Trimble Survey Controller or Tripod Data Systems' (TDS) Survey Pro with Trimble Survey Extensions, the TSC2 Controller can be used to collect and manage both GPS and optical data files simply by switching the controller between sensors. The Trimble TSC2 Controller has a unique changeable cap that enables the use of removable media such as memory cards, GPRS, GPS, camera and product scanning functions. The TSC2 Controller's integrated Bluetooth wireless technology eliminates cable hassles and expedites setup. The expandable media function enables full wireless communication to the Internet in the field with the addition of a GSM/GPRS modem. In the office, data can be transferred using a wireless 802.11 LAN; users in remote locations can use hotspots to share data with the office. The TSC2 Controller also provides USB and serial RS232 communication options; data can be transferred to a PC or another TSC2 Controller using a cable, wireless Bluetooth technology, or CompactFlash or SD memory card media. The vibrant color graphic display allows users to view background maps and check work for greater data control and display; the display is easily viewed in sunlight and is illuminated for ease-of-use even in low lighting. The TSC2 provides a durable keyboard with oversized keys for the most common functions and a dedicated key for quick access to common instrument controls. The user interface allows both full alphanumeric keyboard or touchscreen options, and the Li-ion battery provides up to 30 hours of power. The new controller operates in extreme temperatures of -30 to 60ÂºC (-22 to 140ÂºF) and can withstand a pole drop of 1.2 m (3.9 ft) onto a hard surface.
In addition, Trimble introduced GPSNet version 2.4 software, designed to connect multiple GPS receivers in a reference station network. Key features include: RINEX Shop, a web-based application allowing field users easy access to post-processing files through a simple interface; NTRIP Client, a configuration option where multiple individual data streams require only one TCP port; redundant communications; and enhanced sensors and alarming of out-of-tolerance temperatures and voltages. In addition to offering new features, GPSNet version 2.4 software provides archiving capabilities and true FTP mirroring, providing the ability to upload and delete post-processed files from remote systems.
Also, Trimble introduced RealWorks Survey software version 5.0 to leverage the rich point cloud data set provided by advanced 3D laser scanners. Version 5.0 incorporates a series of new precision tools and features allowing surveyors to produce 2D and 3D information for direct output or export to AutoCAD or Microstation software design packages. The EasyProfile feature uses a pre-positioned profile (fitted to a cross-section of the point cloud) to track through the point cloud. Feature lines are then automatically extracted according to breakpoints in the guide profile. Version 5.0 also offers large database management and new inspection tools-twin-surface inspection, surface-to-model inspection and surface-to-curve inspection-that allow users to perform CAD 5 to point cloud comparisons. The new multi-orthoprojection tool allows users to create aligned multi-orthoimages on successive facades of a building. Users can either create or import drawings, and extrude the segments corresponding to the facade walls along the Z-axis to define the successive projection planes. Users can choose to preview each orthoimage and create them individually or simultaneously. The final results can be exported to a DXF file with references to each orthoimage exported as geo-TIFF file. Version 5.0's Profile Fitter allows internally generated or imported profiles to be interactively positioned relative to the point cloud. In addition, RealWorks Survey version 5.0 enhances volume calculations, regardless of the point cloud density. Now volume calculations can be calculated either between a scanned surface and a user-defined plane, or between two scanned surfaces with the user defining the grid density. A free point cloud data viewer, RealWorks Viewer, is available for download at: www.trimble.com/realworks.shtml. (Trimble, Sunnyvale, Calif.)
