  • GPS Data Errors SELECTIVE AVAILABILITY ERRORS Prior to May 1, 2000, Selective Availability (SA) was a mechanism adopted by the Department of Defense (DoD) to control the achievable navigation accuracy by nonmilitary GPS receivers. In the GPS SPS mode, the SA errors were speci®ed to degrade navigation solution accuracy to 100 m (2D RMS) horizontally and 156 m (RMS) vertically. In a press release on May 1, 2000, the President of the United States announced the decision to discontinue this intentional degradation of GPS signals available to the public. ...

  • Differential GPS (DGPS) is a technique for reducing the error in GPS-derived positions by using additional data from a reference GPS receiver at a known position. The most common form of DGPS involves determining the combined effects of navigation message ephemeris and satellite clock errors [including the effects of selective availability (SA), if active] at a reference station and transmitting pseudorange corrections, in real time, to a user's receiver. The receiver applies the corrections in the process of determining its position [63]....

  • The Global Positioning System(GPS) is a satellite-based navigation system that was developed by the U.S. Department of Defense (DoD) in the early 1970s. Initially, GPS was developed as a military system to fulfill U.S. mili- tary needs. However, it was later made available to civilians, and is now a dual-use systemthat can be accessed by bothmilitary and civilian users [1].

  • It’s fun to uncover something that you aren’t supposed to know about— many software applications and movies on DVD contain what are known as “easter eggs.” However, imagine finding something that you aren’t supposed to find that turns out to be useful and informative. In this chapter, we are going to hunt for GPS easter eggs, delving into the secrets that lie behind the standard menus on your GPS unit to find useful features and diagnostic screens that can give you information about your system and troubleshoot problems that you might have.

  • This paper pro -poses two ideas for adapting standard kinematic techniques to situations that do not naturally allow for the constraint of a fixed baseline. The first calls for extracting the information needed to resolve the integer ambiguity from the very data collected while the kinematic survey is in progress. The second idea addresses the use of the antenna exchange technique for mobile platforms where the original locations of the antennas are not likely to remain stationary during the physical exchange.

  • In this report, a wireless multi-nodes integrated system based on microcontroller, GPS/GPRS/GSM and Google map for wide-area environmental monitoring has been studied and implemented. The system enables us to view the historical and current data recorded of nodes on Google map through a designed website. The environmental data and location of each node are collected and sent to a web server through GPRS service. The web application is developed using PHP, JavaScript and MySQL in combination with embedded Google map service to retrieve and display the data in details.

  • To address these objectives, we collected data and analyzed changes in companies’ choice of auditors and in audit fees, computed concentration ratios and other measures of concentration. We developed an econometric model to evaluate how various factors, including the level of market concentration, could explain fees that public companies paid to their auditors. To obtain the views of public companies and accounting firms on audit competition and challenges, we conducted two surveys.

  • Seven synthetic patient records were manually created to capture typical medical record data: demographic information, contact information, family his- tory, life style data, allergies, immunizations, information on conditions, procedures, prescriptions, and visits to health care providers. These records are by no means com- plete, or unabridged. In practice, clinicians often base care on similar records when treating patients.

  • Ground vehicles can navigate using signals from external navigation systems such as the Global Positioning System (GPS) (Figure 1.1), or by using signals from internal devices such as a compass, an odometer, a gyroscope, an accelerometer, or a full-blown inertial navigation system (INS). In practice, the most reliable and accurate navigation is obtained by combining data from all available sources, including static databases such as a digitized map. This chapter will discuss many of these sources of navigation data, and methods for combining them....

  • This is the first paper using household survey data from two countries involved in an international war (Eritrea and Ethiopia) to measure the conflict’s impact on children’s health in both nations. The identification strategy uses event data to exploit exogenous variation in the conflict’s geographic extent and timing and the exposure of different children’s birth cohorts to the fighting. The paper uniquely incorporates GPS information on the distance between survey villages and conflict sites to more accurately measure a child’s war exposure.
