GPS receiver has a 24 hour a day line-of-sight view to a adequate number of satellites at any spot on the earth such that an individual with a GPS receiver is ready to find out their own longitude and latitude to inside a number of meters, as well as their elevation. Dead-reckoning is properly often called a method of guiding ships, whereby the identified velocity and path of journey of a ship from a known place is used to calculate the current place of the ship. Adverse weather situations can even erode the accuracy of navigation by useless-reckoning. U.S. Pat. No. 5,781,one hundred fifty to Norris discloses a tracking device having an RF transmitter and an RF receiver, every of which have a built-in GPS receiver. GPS place through an RF signal to the receiver, which in flip calculates the place of the transmitter relative to that of the receiver. "line of sight" from its antenna to a receiver for dependable transmission is topic to potential sign loss when operated at the surface of the sea.



Waves can obscure the direct line of sight of the antenna, and will are inclined to submerge the transmitting antenna. This is particularly true for a transmitter that's worn or carried by a person floating on the surface of the water. Transmission of a signal, similar to an RF signal, can be obscured by waves, and the transmitter might be subject to immersion, leading to wasted energy and sign loss. This results in shortened transmitter battery life and decreased transmission reliability. Additional embodiments of the present invention can present an increased level of confidence that the placement indicated for iTagPro bluetooth tracker the person or object is correct. GPS receiver, a sign transmitter to ship a sign indicating a position of the target unit, and a processor to calculate an optimum time interval for transmission of the sign. GPS signal receiver, a compass to provide a reference direction of the locating unit, iTagPro smart tracker a sign receiver to obtain the sign sent by the transmitter of the target unit, a processor to calculate a variety and bearing from the locating unit to the target unit, and an indicator to show the range and bearing.



GPS receiver and a sign transmitter to ship a signal indicating a position of the goal unit. GPS sign receiver and a compass to provide a reference path of the locating unit. An indicator shows the vary, bearing and confidence level. GPS receiver to find out a position of a device. GPS receiver to find out a place of the goal unit. GPS signal receiver and iTagPro support a compass to offer a reference course of the locating unit. An indicator displays the vary and ItagPro bearing from the locating unit to the goal unit. GPS sign at a target unit to determine a location of the target unit, portable tracking tag receiving a GPS signal at a locating unit tracking the target unit to determine a location of the locating unit, iTagPro support calculating an optimum time interval for transmission of a signal from the target unit to the locating unit, the place the signal contains the GPS location of the goal unit, transmitting the signal from the target unit to the locating unit in the course of the optimal time interval, and calculating a variety and bearing from the locating unit to the target unit.



GPS receiver and a sign transmitter to ship a signal including a position of the monitoring unit. Preferred embodiments of the tracking device of the present invention can provide increased reliability of signal transmission from a transmitter to a receiver, and increased confidence within the accuracy of the sign being sent. FIG. 1 is a schematic illustration of a prior art private monitoring system proven in use in a man-overboard scenario. FIG. 2 is a block diagram displaying the elements of a private tracking system in accordance with the present invention. FIG. Three is a plan view of a most well-liked embodiment of a graphical display of the private monitoring system of FIG. 2 . FIG. Four is a plan view of another embodiment of a graphical show of the non-public tracking system of FIG. 2 . FIG. 5 is a block diagram exhibiting the parts of a private tracking system in accordance with another embodiment of the current invention.



FIG. 6 is a block diagram showing the elements of a personal tracking system in accordance with yet another alternative embodiment of the current invention. FIG. 7 is a block diagram displaying the elements of a private monitoring system in accordance with an extra different embodiment of the current invention. 2 is shown in FIG. 1 in a man-overboard situation. 4 having a GPS machine 6 is proven at the crest of a wave. 8 having a GPS device 6 is shown at the trough of a wave. GPS gadgets 6 include a transmitter that sends a sign 10 , e.g., an RF sign, iTagPro USA to a GPS gadget 12 on a ship 14 . GPS device 12 has a receiver to receive the alerts 10 sent by GPS devices 6 . Each of the GPS units ascertains its longitudinal and latitudinal position by buying signals from GPS satellites 16 that orbit the earth.
