1. A method of navigating to a target, comprising: providing a location of a target to an object being navigated;creating at least three marks by deploying a plurality of markers from at least one aerial vehicle, wherein each of said plurality of markers comprises a Radio Frequency Identification (RFID) tag, a bright day-glow color detectable by an electro-optic seeker, and an exothermic material detectable in the infrared (IR) electromagnetic frequency;receiving at said object being navigated a first set of signals being sent by said plurality of markers;receiving at a dedicated aerial vehicle a second set of signals sent by said plurality of markers;using said second set of signals to determine a location of said plurality of markers in relation to said target;transmitting said location of said plurality of markers in relation to said target from said dedicated aerial vehicle to said object being navigated;calculating an angle to said plurality of markers using an electronic processor on-board said object being navigated based on information from said first set of signals; anddetermining a location of said object being navigated in relation to said target using said calculated angle to said plurality of markers and said location of said plurality of markers in relation to said target. 2. The method of claim 1, wherein said first set of signals and said second set of signals comprise signals sent by said exothermic material being detectable in the infrared (IR) electromagnetic frequency. 3. The method of claim 1, wherein said first set of signals and said second set of signals comprise signals being sent by said bright day-glow color detectable by an electro-optic seeker on said object being navigated. 4. The method of claim 1, wherein said first set of signals comprise signals sent by said exothermic material being detectable in the infrared (IR) electromagnetic frequency and said second set of signals comprise signals being sent by said bright day-glow color detectable by an electro-optic seeker on said object being navigated. 5. The method of claim 1, wherein said first set of signals comprise signals being sent by said bright day-glow color detectable by an electro-optic seeker on said object being navigated and said second set of signals comprise signals sent by said exothermic material being detectable in the infrared (IR) electromagnetic frequency. 6. The method of claim 1, wherein said first set of signals and said second set of signals comprise radio frequency (RF) signals sent from said RFID tags and said method further comprises causing each said RFID tag to activate and start sending data by emitting an activation signal from a transceiver and antenna associated with said object being navigated. 7. The method of claim 1, wherein said first set of signals comprise radio frequency (RF) signals sent from said RFID tags and said second set of signals comprise signals sent by said exothermic material being detectable in the infrared (IR) electromagnetic frequency, and said method further comprises causing each said RFID tag to activate and start sending data by emitting an activation signal from a transceiver and antenna associated with said object being navigated. 8. The method of claim 1, wherein said first set of signals comprise radio frequency (RF) signals sent from said RFID tags and said second set of signals comprise signals being sent by said bright day-glow color detectable by an electro-optic seeker on said object being navigated, and said method further comprises causing each said RFID tag to activate and start sending data by emitting an activation signal from a transceiver and antenna associated with said object being navigated.
