Based on the Global Positioning System (GPS), VELOC (vehicle location) is designed to be a vehicle information system for fleet management adaptable to various user groups, e.g., haulage and delivery companies, and service enterprises with vehicle fleets. The needs of these groups vary with respect to position accuracy, position update rate, and type of communication. The authors describe the requirements, specifications, and performance of VELOC. Special emphasis is placed on some substantial features of the VELOC center, namely the integration of DGPS, a comfortable user interface, and handling of vehicle positions on digital maps.<>

The authors describe the design, functional capabilities, and performance characteristics of the DoD standard five-channel miniaturized (less than 3/8 ATR) airborne GPS (Global Positioning System) receiver. The details of the receiver's hardware and software architectures are presented, along with a description of its functional capabilities. In addition, performance data captured during both stationary and dynamic testing, with or without host vehicle aiding, and under jammed and unjammed conditions, are presented.<>

Summary form only given. The authors present a practical application of an attitude match algorithm useful for correcting boresight errors of an airborne LOS (line-of-sight) tracking sensor system. In order to provide high-quality information to other sensor and/or weapon control system, the tracker must be accurately aligned to a common attitude coordinate frame. It operates by comparing computed attitude from a high-quality aircraft INU, with the attitude computed using a gimballed gyro package inside of the sensor system. The residual attitude differences measured during aircraft and gimbal maneuvers are a direct indication of mechanical misalignment, tracker initial attitude errors, gimbal biases, and gyro uncertainties, and are used in a Kalman filter to estimate these quantities. A detailed analysis of a transfer alignment and instrument calibration filter for a gimballed sensor has been carried out. A filter sizing study has been performed, and the sensitivity of the suboptimal filter to the unmodeled error states and the incorrectly modeled measurement noise and errors has been investigated.<>

Summary form only given. Given the special requirements of the payload area of the Super Loki sounding rocket the author examines two options for the telemetry package. The first option consists in relying totally on GPS (Global Positioning System) antenna and a translator attached to the vehicle. This translator will continuously download the navigation messages picked from GPS satellites to a ground station. On the ground these navigation messages can be analyzed. The second option consists in using commercially available small accelerometers or gyroscopes to develop a quasi-inertial navigation unit. This unit either processes the accelerometer's output onboard or downloads it to a ground station for further analysis. A comparative study has been performed to analyze these two options to select the optimal in terms of weight, performance, and cost. The development and design of systems, subsystems, and components required to build a prototype has also been considered.<>

In the framework of safety, the authors propose a novel automatic correction system for nautical charts. The hardware mainly consists of an X-Y plotter and microcomputer, while the software consists of system program and database to accommodate the information of correcting the chart. In the database, the information given by Japanese Notices to Mariners, which is published by the Japan Maritime Safety Agency, is arranged into a compact form. This compactness allows the system to be run even on a microcomputer, to be simple in configuration, and to be operational onboard. The performance of the system is discussed in comparison with manual correction, and the application of the system to actual correction is investigated. The results show that the system works on 96% of the items of the Japanese Notices to Mariners. It is expected that this system can be applied to American, British, and other foreign charts with a few modifications in the hardware and software.<>

The NavTrax System, a dispatch-type automatic vehicle location and navigation system, is discussed. Attention is given to its positioning, communication, digital mapping, and dispatch center components. The positioning module is a robust GPS (Global Positioning System)-based system integrated with dead reckoning devices by a decentralized-federated filter, making the module fault tolerant. The error behavior and characteristics of GPS, rate gyro, compass, and odometer sensors are discussed. The communications module, as presently configured, utilizes UHF radio technology, and plans are being made to employ a digital cellular telephone system. Polling and automatic smart vehicle reporting are also discussed. The digital mapping component is an intelligent digital single line road network database stored in vector form with full connectivity and address ranges. A limited form of map matching is performed for the purposes of positioning, but its main purpose is to define location once position is determined.<>

The Navigation Sensor System Interface (NAVSSI) project is a new system being designed with two primary objectives: processing/distribution of navigation data and the display/operation of digital nautical charts. The goal is for the digital nautical chart to replace the paper chart as a legal means of ownship navigation plotting. NAVSSI will be the US Navy Electronic Chart Display & Information System (ECDIS). The author introduces the project and explores the use of digital nautical charts for ownship navigation with NAVSSI.<>

The author gives the complete relativity effects as applied to a ground-based receiver's local coordinate time. The current Global Positioning System (GPS) relativity corrections were based on an earth-centered inertial reference frame. The derivation assumed that the receiver obtained inertial GPS coordinate time from the satellites. However, the receiver has been treated tacitly as being stationary in the inertial frame. The problem is that relativity effects in GPS are compensated only for the moving satellites relative to the frame. It is shown that relativity effects for a ground-based receiver include gravity and earth rotation. Airborne GPS receivers have larger effects, and spaceborne GPS receivers have the worst uncompensated relativity effects.<>
