1. A navigation data sharing system, comprising: two or more navigation instruments connected with a network of a navigation system; andtwo or more sensors connected with the network and configured to detect information to be used by the navigation instruments;each of the navigation instruments comprising: a switch control module configured to switch between a state in which the navigation instrument functions as a mother unit and a state in which the navigation instrument functions as a child unit;a delivery module configured to transmit through the network, when one of the navigation instruments functions as the mother unit, representative sensor selection related information to another one of the navigation instruments that functions as the child unit, the representative sensor selection related information being a configurable priority which is set in advance to each sensor information and including information about which sensor is to be used as a representative sensor by the mother unit from among the two or more sensors of a sensor group, each of the sensors of the sensor group being configured to detect the same physical property, and only one of the navigation instruments functioning as the mother unit at any given time; anda representative sensor selecting module configured to select, when one of the navigation instruments functions as the child unit, the representative sensor from which the child unit is to receive data representative of the physical property, based on the representative sensor selection related information received from the navigation instrument that functions as the mother unit, such that the child unit and the mother unit receive the data from the representative sensor. 2. The navigation data sharing system of claim 1, wherein the navigation instrument uses an algorithm as the representative sensor selection related information to select the sensor to be used. 3. The navigation data sharing system of claim 1, wherein the navigation instrument uses information that specifies the sensor to be used, as the representative sensor selection related information. 4. The navigation data sharing system of claim 1, wherein the delivery module provided to the navigation instrument that functions as the mother unit transmits the representative sensor selection related information to the navigation instrument that functions as the child unit when the representative sensor selection related information is updated. 5. The navigation data sharing system of claim 1, further comprising a navigation data converting device, the navigation data converting device including: a first access module connected with the network;a second access module connected with the network, the second access module being configured to connect with a device otherwise incapable of communicating with the network and receiving data from the device such that the received data may be transmitted through the network; andthe representative sensor selecting module configured to select the sensor to be used by a device connected to the second access module, based on the representative sensor selection related information received from the navigation instrument that functions as the mother unit. 6. The navigation data sharing system of claim 1, wherein the navigation instrument is a ship navigation instrument. 7. The navigation data sharing system of claim 1, wherein the representative sensor selecting module selects as the representative sensor the highest priority sensor outputting navigation data. 8. The navigation data sharing system of claim 7, wherein a sensor with the next-highest priority is selected as the representative sensor when navigation data cannot be acquired from the highest priority sensor for more than a predetermined period of time. 9. A navigation instrument which is configured to communicate with an other navigation instrument via a network of a navigation system on a ship, the navigation instrument comprising: a switch control module configured to switch between a state in which the navigation instrument functions as a mother unit and a state in which the navigation instrument functions as a child unit;a representative sensor selecting module configured to select as a representative sensor one of a plurality of sensors of a sensor group that are connected to the navigation instrument through the navigation system, each of the sensors of the sensor group being configured to detect the same physical property, the representative sensor selecting module selecting the representative sensor from which to receive data representative of the physical property based on representative sensor selection related information that is information about which sensor of the sensor group is to be used, the representative sensor selection related information being a configurable priority which is set in advance to each of the sensors in the sensor group; anda delivery module configured to transmit, when the navigation instrument functions as the mother unit, the representative sensor selection related information through the network to the other navigation instrument that functions as the child unit, such that the child unit is controlled, based on the representative sensor section related information, to select the representative sensor from which to receive the data representative of the physical property so that the child unit and the mother unit receive the data from the representative sensor. 10. The navigation instrument of claim 9, wherein the representative sensor selecting module selects the sensor to be used based on the transmitted representative sensor selection related information when the navigation instrument functions as the child unit. 11. The navigation instrument of claim 9, wherein the representative sensor selecting module selects as the representative sensor the highest priority sensor outputting navigation data. 12. The navigation instrument of claim 11, wherein a sensor with the next-highest priority is selected as the representative sensor when navigation data cannot be acquired from the highest priority sensor for more than a predetermined period of time. 13. A method for controlling navigation instrument, comprising: configuring the navigation instrument to communicate via a network of a navigation system on a ship to an other navigation instrument;operating the navigation instrument as a mother unit and to transmit representative sensor selection related information to the other navigation instruments that operates as a child unit through the network, the representative sensor selection related information being information about which sensor is to be used as a representative sensor among a plurality of sensors of a sensor group connected to the navigation instruments through the network, each of the sensors of the sensor group being configured to detect the same physical property, and the representative sensor selection related information being a configurable priority which is set in advance to each of the sensors in the sensor group; andoperating the child unit to select, based on the representative sensor selection related information, the representative sensor from which to receive the data representative of the physical property so that the child unit and the mother unit receive the data from the representative sensor. 14. The method of claim 13, wherein the operating one of the navigation instruments as the mother unit includes selecting as the representative sensor to be used which is the highest priority sensor outputting navigation data of the group. 15. The method of claim 14, wherein a sensor with the next-highest priority is selected as the representative sensor when navigation data cannot be acquired from the highest sensor for more than a predetermined period of time. 16.
