Table 2-3.—TESS (3) Environmental Programs—Continued PROGRAM Ambient Noise (AN) APPLICATION Provides noise predictions. Corrects for local, seasonal, directional, and omnidirectional levels. CONSIDERATIONS Designed for deep water. Unreliable predictions for water depths less than 300 m deep. Tactical Oceanographic Acoustic Spreadsheet (TOAS) Computes sensor prediction data using platform/sensor data bases, the propagation loss model, and associated data bases. Requires minimal user response. Many considerations; refer to TESS 3.0 User’s Guide. Edit Orbital Element Set (EDORD) Allows editing of satellite orbital Few limitations for satellite orbital data. data. Orbital Satellite Prediction Provides satellite-pass summaries Rise and set time error ranges from (ORBSAT) consisting of rise and set time, pass 1 to 5 sec. Predictions limited by duration, ship position during the the number of satellites for a pass, and maximum elevation. specific latitude area. Geostationary Satellite (GSAT) Computes antenna-aiming data Assumes a stationary platform. Prediction based on operator-specified ship location and bearing, and the satellite longitude. TESS-NEXT CENTURY (NC) TRANSITION The TESS-Next Century (NC) Transition was released as an interim system to fill the void between TESS (3) and the full deployment of TESS-Next Century. As discussed in chapter 1, significant changes to TESS were introduced with this system, with Internet access being the most important advantage. In addition to Internet access, the TESS-NC Transition includes a wide variety of commercial and government software programs. Commercial software programs include the Windows NT operating system, Microsoft Office, and commercial web browsers. Government software includes the Joint METOC Viewer (JMV), the Electro- Optical Tactical Decision Aid (EOTDA), and SMOOS interface software. In addition, several of the environmental programs in MIDDS are installed with the TESS-NC Transition. TESS-NEXT CENTURY TESS-Next Century (TESS-NC) retains several of the same software packages as the TESS-NC Transition system. As of this writing, the total complement of software programs has not been fully developed. TESS-NC operates using the Windows NT Server and Workstation Operating System and maintains SMOOS interface capability. Commercial word processing and graphics programs center around Microsoft Office programs. Commercial web browsers are also included with the system. Government software programs include the JMV program, the EOTDA program, and refractivity prediction programs, which are discussed shortly. Additional government software includes various GFMPL programs, such as TIDES and SURF, and software programs from MIDDS, such as the SAND application (discussed in chapter 1). As mentioned in chapter 1, TESS-NC also includes a data base server and workstation that operate using an HP-UX (UNIX) Operating System. This workstation is used to access tactical applications programs via the Global Command and Control System-Maritime (GCCS-M). In addition, the SPPED/ICAPS II Integrated Product (SIIP) is run from this workstation. SIIP is a series of several integrated environmental programs that access historical and tactical data bases. SIIP products include sound speed profiles (SSPs), acoustic raytraces, ocean data analysis products, passive acoustic propagation loss (PAPL) displays, sensor performance prediction (SPP) protiles, and ambient noise (AN) data. 2-11
