The NAV 5000 can be set to use any of three modes to calculate positions: two-dimensional (2D), three-dimensional (3D), and the Automatic (AUTO) Mode. In 2D, the unit uses 3 satellites to calculate latitude and longitude: altitude is a user-entered variable.

  • Page 12: The Gps System

    THE GPS SYSTEM The Global Positioning System (GPS) is a highly accurate, worldwide navigation and positioning system that can be used 24 hours a day. Designed at the impetus of the US Department of Defense and primari- ly for military use, GPS is available to a variety of users worldwide, including recreational boaters, fishing and shipping fleets , general and commercial aviation, surveyors, and engineers.

  • Page 13: Interference

    THE GLOBAL POSITIONING SYSTEM The receiver then assesses the transmission time and signal quality from each satellite, and multiplies the difference in the transmission time by the speed of light (186,000 miles per second) to arrive at an estimate of the satellite's distance from the receiver (range). Next, the unit calculates (by triangulation) and displays the position fix.
  • Page 14 Monitor stations and ground antennas throughout the world passively track the GPS satellites and relay data to the master control station. Exact satellite position and signal-data accuracy can therefore be constantly updated and maintained. Minor discrepancies between where the satellite "thinks" it is and where the monitor station "knows" it is can also be adjusted.

The unit shuts itself off two minutes after this warning appears. You may continue to operate only from external power. This message appears when the level of external power being supplied to...

  • Page 57: Position (Pos)

    POSITION (POS) When the POS key is pressed the NAV 5000 checks its Almanac to determine which satellites are scheduled to be in view, and which of the available satellites will give the best geometry for a position fix. lf satellites are scheduled to be in view, the receiver turns on and the display goes to the receiver screen.
  • Page 58 The Instafix satellite search algorithm devotes all five channels to the search for the satellite the Almanac indicates is directly overhead, given your last fix or initial position. This greatly shortens the length of time required to obtain a position fix. The first satellite is usually located in a few seconds, but when satellite geometry is not optimum, it takes up to a minute.

  • Page 59: Position Display

    A position fix is calculated when enough satellites for the mode you have chosen have been acquired. lf the unit was initialized correctly, the first position fix can be made in 55 seconds or less. Subsequent fixes can be made in about 30 seconds, if the previous fix was made in the last hour and you are using the same set of satellites.
  • Page 60 Press the DOWN ARROW to see the current datum, date, and time. Press the DOWN ARROW again to see which satel- lites were used to compute the position, the satellite signal quality, and the geometric quality of the fix. (See page 3-9 for a description of SQ and GQ.

  • Page 61: Continuous Operation

    Continuous Operation When the unit is in continuous operation, it updates the position fix approximately every second. As satellites set or their signals become blocked, and as other satellites rise, the unit occasionally changes which satellites are being used. This does not affect the unit's updating the position fix. When the unit is operating from external power, it does not turn off until ON/ OFF is pressed or power is lost.

  • Page 62: Search And Acquisition Errors

    Unit searches constantly. Insufficient Number of Satellites The NAV 5000 checks its Almanac before beginning to search for satellites. The receiver will not turn on if the Almanac indicates that not enough satellites are within view to establish a position fix.

  • Page 63: Initialization Error

    The unit may be unable to locate satellites under the following conditions: The antenna is not positioned correctly. The satellite signals are blocked from view by buildings, mountains, etc. There are signal reflections that can be corrected by moving the antenna. There are satellite outages.

  • Page 64: Accuracy Warning Symbol

    Briefly, since the unit already has an Almanac, it skips the first part of Sky Search, which collects a new Almanac. The unit simply searches the sky for satellites until it locates enough to verify its position and calculate a new position fix. This usually takes 15 minutes. lf the unit does not have a new position fix after about 20 minutes, either reinitialize the unit (page 2-5 or 4-27) or enter Sky Search with AUX 5 (page 5-8) to collect a new Almanac.

  • Page 65: Old Data

    This symbol appears on all three screens of the position fix when the SQ from one or more satellites is 3 or less. Old Data The unit automatically updates its position every second. If a satellite signal is lost, or a satellite sets or becomes obstructed, the unit switches to other satellites to update the fix.

  • Page 119: Fixes Vary A Lot

    FIXES VARY A LOT The position accuracy of the NAV 5000 is affected by several variables, the most important of which is the GQ (geometric quality). Therefore, the specified accuracy of 15 meters RMS in 2D is statistical, not absolute. Also, it is assumed that GQ is greater than 7 and SQ is at least 7.

  • Page 124: Using The Unit Near The Poles

    This means that small changes in position can cause large variations. The inherent accuracy of the NAV 5000 does not change near the poles, but this mathematical sensitivity problem can cause position and velocity-related data to appear unstable when the unit is operated at latitudes greater than 85 degrees north or south of the equator.
