Abstract

Provided is a system for detecting an accident location, including: a navigation apparatus to extract identification information of a preinstalled apparatus, first distance information between the apparatus and at least one base station, and second distance information between the apparatus and a geostationary satellite, when an impact is applied to the apparatus; and an apparatus control center to compute location information of the navigation apparatus based on the identification information, the first distance information, and the second distance information, wherein the at least one base station receives the first distance information from the navigation apparatus and transmits the first distance information to the apparatus control center, and the geostationary satellite receives the second distance information from the navigation apparatus and transmits the second distance information to the apparatus control center.

Claims

1. A system for detecting an accident location, comprising:

a navigation apparatus configured to be mounted in a vehicle;

a preinstalled apparatus mounted in the vehicle, the navigation apparatus in communication with the preinstalled apparatus, the navigation apparatus operable to;

determine whether an impact is applied to the preinstalled apparatus, the impact indicating that an accident has occurred to the vehicle at the accident location;

in response to determining that the impact to the preinstalled apparatus has occurred, extract an identification information of the preinstalled apparatus;

extract a first distance information between the navigation apparatus and at least two base stations; and

extract a second distance information between the navigation apparatus and a geostationary satellite; and

an apparatus control center in communication with the navigation apparatus, the apparatus control center computing location information of the navigation apparatus and the accident location based on the identification information, the first distance information, and the second distance information, wherein at least one base station receives the first distance information transmitted from the navigation apparatus and transmits the first distance information to the apparatus control center, and the geostationary satellite receives the second distance information transmitted from the navigation apparatus and transmits the second distance information to the apparatus control center,

wherein the navigation apparatus comprises an alerting unit to generate an alert when the impact is applied to the apparatus, and

wherein the alerting unit receives alert request information from the apparatus control center to thereby generate the alert.

2. The system of claim 1, wherein the apparatus control center computes location information of the navigation apparatus based on the first distance information received from at least three base stations, the second distance information, and the identification information.

3. The system of claim 1, wherein the navigation apparatus further comprises:

a determining unit to determine whether an impact is applied to the preinstalled apparatus;

a power unit coupled to the determining unit, the power unit supplying power to the navigation apparatus when the impact is applied to the preinstalled apparatus; and

a communication unit coupled to the determining unit and the power unit, the power unit supplying power to the communication unit, the communication unit transmitting identification information of the preinstalled apparatus, first distance information between the apparatus and at least one base station, and second distance information between the apparatus and a geostationary satellite to the at least one base station, the geostationary satellite, and an apparatus control center.

4. A method of detecting an accident location, comprising:

determining, via a navigation apparatus, whether an impact is applied to a preinstalled apparatus, the navigation apparatus and the preinstalled apparatus mounted in a vehicle, the navigation apparatus in communication with the preinstalled apparatus, the impact indicating that an accident has occurred to the vehicle at the accident location;

in response to determining that the impact to the preinstalled apparatus has occurred, extracting an identification information of the navigation apparatus;

transmitting, from the navigation apparatus, a first distance information between the navigation apparatus and at least two base stations to the at least two base stations;

transmitting, from the navigation apparatus, a second distance information between the navigation apparatus and the geostationary satellite to the geostationary satellite;

receiving, at the apparatus control center, the identification information of the navigation apparatus;

receiving, at the apparatus control center, the first distance information between the navigation apparatus and the at least two base stations from the at least two base stations;

receiving, at the apparatus control center, the second distance information between the navigation apparatus and the geostationary satellite from the geostationary satellite; and

computing, via the apparatus control center, the accident location based on the identification information, the first distance information, and the second distance information,

wherein the navigation apparatus comprises an alerting unit to generate an alert when the impact is applied to the apparatus, and

wherein the alerting unit receives alert request information from the apparatus control center to thereby generate the alert.

5. The method of claim 4, wherein the accident location is computed based on first distance information received from at least three base stations, the second distance information, and the identification information.

6. The method of claim 4, wherein the navigation apparatus generates an alert when the impact to the preinstalled apparatus has occurred.

7. The method of claim 4, wherein the navigation apparatus receives alert request information from the apparatus control center and generates an alert.

8. The method of claim 4, wherein the navigation apparatus further comprises a determining unit to determine whether the impact to the preinstalled apparatus has occurred.

9. The method of claim 4 further comprising:

supplying power to the navigation apparatus when the impact to the preinstalled apparatus has occurred, the power being supplied from a power unit coupled to the navigation apparatus.

10. The method of claim 9, wherein the navigation apparatus further comprises a communication unit coupled to the power unit, the power unit supplying power to the communication unit when the impact to the preinstalled apparatus has occurred.

11. The method of claim 10, wherein the communication unit transmits the identification information, the first distance information and the second distance information.
