  1. What’s new in GPS Technology

  2. Modernized GPS Satellites • Modernized GPS satellites are now in orbit, and all of these satellites are capable of transmitting L2C signals (civilian signals on the satellite L2 carrier). These satellites represent a significant first step in the GPS Modernization program planned by the United States. • With the new L2C signals, your L2 measurements can be more robust, making your GPS observations even more reliable. All you need to benefit from the stronger signals is a GPS receiver capable of tracking them.

  3. The new L5 carrier signal • Now that the first L2C satellites are in orbit, it's possible to look ahead to the next modernized GPS signal on the horizon, the entirely new L5 carrier. The U.S. Air Force has scheduled the launch of the modernized GPS Block IIR satellite that will host an L5 demonstration payload for June 30 of this year. • The arrival of L5 will make the number of GPS carriers total three. L5 will provide a higher power level than the other carriers. As a result, acquiring and tracking signals will be easier.

  4. Trimble R8 GNSS • The Trimble® R8 GNSS System is a multi-channel, multi-frequency GNSS (Global Navigation Satellite System) receiver, antenna, and data-link radio combined in one compact unit. • It contains Trimble R-Track technology to support all GPS signals, including the new L2C signal and the coming L5 signal of GPS Modernization. • It also supports GLONASS.

  5. GeoXH– 2005 Series H-Star™ technology • Subfoot (30cm) with internal antenna • 8” (20cm) with Zephyr antenna • Windows Mobile Version 5.0 • 512 MB disk and SD removable storage • Bluetooth • 802.11b Wireless LAN –Hot spots • PPA

  6. GeoXH and ProXH - PPA

  7. Send/Receive via email • Send files directly to the field • Data files (SSF or SHP) • Data dictionaries • Waypoints • Configuration files • Background files • Coordinate systems • Email completed projects directly back to the office`

  8. Trimble Nomad handheld • Mapping & GIS will offer the Trimble Nomad 800LC handheld version with PDA keypad

  9. Trimble Nomad 800LC Handheld • Mapping & GIS Trimble Nomad 800LC handheld • Windows Mobile 6 operating system • 806 MHz processor, 1 Gb Flash memory • VGA (640 x 480) display, sunlight readable • Integrated 2 MP camera, fixed focus • Integrated SiRFStar III GPS • PDA keypad • Boot with USB client and 9-pin serial port • SDIO slot, supports SD memory cards • Removable Li-ion battery • Bluetooth 2.0 + EDR, wireless LAN 802.11 b/g • Rugged: IP67 (water/dust), 1.22m drop spec

  10. Benefits of the Zephyr antenna for a GeoXH and ProXH receiver • Raised above body • Less subject to interference • High quality survey grade antenna • Large integrated groundplane • L1/L2 antenna required for 20 cm accuracy with H-Star processing

  11. Useful Tool • Asset / Data Mangement Tool • Sewer / Water Valves • Pipeline • Utility Poles • Centerline • GASB-34 Requirements • Evidence Recording

  12. More Tools • Environmental Impact • Wetlands Delineation • Timber Stand • Illegal Dumping • Signage

  13. TrimPix technology: • What is TrimPix technology? Wireless Camera Capability for the latest Trimble handhelds

  14. What is TrimPix technology? • Using WiFi capable Nikon digital cameras CoolPix models S7c and P3 – wireless LAN connection to GeoExplorer, Juno ST, Recon and Ranger handhelds • You can link high resolution digital images to your GPS points • Using Fotonation – “Connected Photography” software – enables PTP (Picture Transfer Protocol)

  15. What it is being offered? • Free web download – required to fill in a Survey first • Two parts to software – PC application and handheld application • Handheld application needs to be running to enable PTP • Under Start – Settings – Connections – WiFi Camera

  16. Better Accuracy Differential Correction • WAAS • http://www.nstb.tc.faa.gov/ • USGS Beacon system • http://www.navcen.uscg.gov/dgps/ • Postprocessed • Pathfinder Office or GPSAnalyst • Real Time-High accuracy • Reference Station – FDOT free service

  17. Example scatter plots

  18. Current WAAS – July 17, 2007

  19. Why postprocess your data?

  20. GPS Pathfinder Office or GPS Analyst – Post Processing H-Star • Accuracy: H-Star technology • GPS Pathfinder ProXH receiver and GeoXH handheld • Requires minimum of 3 good quality dual-band reference stations within 200 km, or one good quality dual-band reference station within 80 km • 20 cm accuracy achievable using Zephyr™ external antenna

  21. H-Star Postprocessing

  22. H-Star Postprocessing

  23. H-Star Postprocessing

  24. Accuracy Summary • Output window shows status of processing

  25. Latest Software Releases Major Releases • TerraSync v3.00 • GPS Pathfinder Office v4.00 Minor Releases • GPS Pathfinder Tools SDK v2.20 • GPS Controller v2.11 • GPS Analyst v2.10 • GPScorrect v2.20

  26. What’s new? – 64-bit support • 64-bit Windows XP and Vista support for GPS Pathfinder Office software • New Installshield-streamlined procedure • Improved handling of file security during installation

  27. What’s new? – Licensing • Mapping & GIS License Manager • For GPS Analyst and now also for GPS Pathfinder Office software • Allows per-session rather than per-seat use of valuable licenses • Enables Licenses to be unhooked and used in a standalone environment • Replaces client-server installation

  28. What’s new? – Image files • Applicable to TerraSync Professional Edition and GPS Pathfinder Office • Background images • Support for latest compression technologies • Higher resolution with smaller file sizes • New to TerraSync Pro • Images can now be tiled as a mosaic • Raster files can be stacked • MrSID backgrounds now load faster than ever • New Background file formats • Enhanced Compression Wavelet (.ecw) • MrSID Gen 3 (.sid) • JPEG 2000 (.j2c, .jp2)

  29. Background Images • Layers • Shapefiles (.shp) • Vector (.ssf, .cor, .imp) • Raster (.bmp, .tif, .ecw, .jpg, etc.)

  30. Background Images • Multiple raster file overlays • Overlay different formats • White shows as transparent: layer beneath is revealed • User selects as many tiles as required for an area mosaic • Only those being displayed use memory • The closer you zoom the faster the redraw

  31. Background Images • Multiple files - prerequisites • Must be geo-referenced • Must all be in the same configured coordinate system • Must have a coordinate system file • Must be stored in the same location
