CAST manages a suite of navigation, mapping and survey-grade GPS hardware and processing software to serve almost any mapping need.  

As early as 1992, CAST was designated as a Center of Excellence for "Global Positioning System Mapping Systems: Training and Research" by Trimble Navigation Ltd and has continued to be actively involved in applying GPS in a variety of research projects and outreach activities.  Through this corporate agreement and with support from a 2003-2005 NSF Major Research Instrumentation grant (BCS-0321286) and University of Arkansas TELE funds, CAST obtained and now maintains a complete suite of Trimble GPS mapping and surveying hardware. 

In 2004, CAST was designated as a Center of Excellence for "Photogrammetry and Remote Sensing" by Leica Geosystems and expanded its activities in high-accuracy, large-scale mapping. In 2010 the University received NSF award 0918070 (CI-TRAIN Project) which allowed the acquisition of a number of new instruments including a suite of Leica GNSS receivers and software.

The current GPS equiptment configuration now available at the Center for research and teaching purposes is:

    • (3) three Leica Geosystems Viva G15s with C10 data loggers
    • (2) two 5700 receivers with Zypher Geodetic antennas,
    • (1) one 5800 integrated antenna and receiver,
    • (1) one UHF radio for RTK applications
    • (1) one 5600 D2 Robot Total Station,
    • (2) two GeoExplorer XH's,
    • (2) two GeoExplorer XT's,
    • (3) five GeoExplorer XM's,
    • (2) two ProXRS's
    • (20) twenty Juno ST's.

 

The Viva GNSS and 5700/5800 equipment is configured to work with the on-campus NetRS base station in real-time kinematic mode via CDMA cell-modems.  For the Trimble mapping units Trimble Pathfinder Office, TerraSync and ArcPad with GPScorrect is used for mapping applications, while Leica Geomatics Office, Trimble Geomatics Office, JPL's GYPSY-OASIS II and UNAVCO's TECQ software is used for Surveying/Geodetic applications.

This equipment is available for checkout by faculty, staff, and students of the university working on internally or externally funded research. For access contact Malcolm Williamson (479.575.6159).
