Assisted GPS (A-GPS) has been built to supply vastly better functions, assisting GPS paintings greater and swifter in virtually any situation. delivering a close examine all of the technical points and underpinnings of A-GPS, this targeted ebook locations emphasis on functional implementation. The e-book experiences average GPS layout, assisting you realize why GPS calls for information within the first position. you find how A-GPS allows the computing of a place from navigation satellites within the absence of specified time a subject matter no longer lined in the other booklet. furthermore, you the best way to layout and study a excessive sensitivity GPS receiver and make certain the plausible sensitivity. The booklet presents precise worksheets that convey tips to compute, examine, and increase the processing achieve from the enter sign on the antenna to the sign after the correlators. those worksheets are utilized in the e-book to generate households of curves that perfectly symbolize receiver sensitivity, parameterized by way of entrance finish noise determine, coherent and noncoherent integration instances. From this paintings a legislation of feasible sensitivity is derived and defined within the ebook. This state of the art quantity discusses exact types of tips facts, criteria for A-GPS, and govt mandates for situation of cell phones. you furthermore mght locate assurance of destiny international navigation satellite tv for pc structures and the way they are often designed particularly for instant-fixes and excessive sensitivity. The e-book beneficial properties various tables, worksheets, and graphs that illustrate key subject matters and supply the similar of a technical guide for engineers who layout or use A-GPS.

Sample text

The first week number rollover occurred on August 21, 1999, coincidentally just a few months before the other great rollover happening, Y2K. This meant that the GPS week rollover received quite a lot of media attention at the time. Most GPS receivers had little or no trouble with the week number rollover. The next such rollover will be a few leap seconds before midnight UTC at the end of April 6, 2019. The overall quality of the broadcast ephemeris has improved since GPS began in 1980. 9 Broadcast data organization: frames, subframes, and words.

If you know the current week, then the TOW is all you need to know the time and the full pseudorange. If you do not know the current week, then you can get it from the week number contained in subframe 1. The broadcast week number is 10 bits, so it counts to 1,023 weeks and then starts again at week 0. GPS week 0 began at midnight (UTC) the beginning of January 6, 1980. The first week number rollover occurred on August 21, 1999, coincidentally just a few months before the other great rollover happening, Y2K.
