The embodiment of the invention provides a safe wireless communication method and system based on a navigation satellite. The method mainly comprises steps that a mobile terminal acquires the position data of itself, encrypts the position data, and transmits the encrypted position data to the navigation satellite via a satellite communication link; the navigation satellite transmits the encrypted position data to a background command server of the mobile terminal via satellite communication link and the background command server decrypts the encrypted position data in order to acquire the position data of the mobile terminal. According to the method, the background command server may remotely monitor the position data and the state data of the mobile terminal in real time and timely feeds control information back to the mobile terminal so as to increase scheduling command efficiency. The navigation positioning of the mobile terminal may operate in various modes and is less dependent on a specific positioning satellite so as to effectively increase the navigation communication efficiency of the mobile terminal. A unique short message wireless communication way of a Beidou first generation guarantees data transmission reliability.

The invention provides an authentication and encryption system and method for broadcasted differential data. The method comprises the following steps: a cloud side encrypts all differential data needing to be broadcasted through a satellite broadcast way, and uploads the differential data to a satellite through an on-satellite channel; the satellite broadcasts the differential data through an L-BAND broadcast way; an online terminal initiates an authentication request to the cloud side through the internet, and receives a differential data decryption key issued by the cloud side after the authentication request is successfully initiated; the terminal stores the differential data decryption key at the local; the (online or offline) terminal performs the decryption by using the decryption key stored at the local after receiving the differential data broadcasted by the satellite through the broadcast way, and performs the high-precision positioning solution by using the differential dataafter decrypting the differential data. Through the system and method provided by the invention, only the authorized user is permitted to use the broadcasted differential data, and the use of each ofthe online scene and the offline scene is compatible.

The invention discloses a service type detection method and a service type detection device, and belongs to the field of satellite mobile communication. The method comprises the following steps of acquiring first message information in first service data if a service type corresponding to message header information is not found, and acquiring the second message information of second service data of a service type detected within a preset time period before current time; calculating first similarity between the first message information and each piece of second message information, and judging the minimum first similarity is more than or equal to preset similarity or not; if the maximum first similarity is more than or equal to the preset similarity, determining the service type of the second service data corresponding to the second message information corresponding to the maximum first similarity as the service type of the first service data. According to the method and the device, calculation for the detection of the service type in other ways when the service type is not detected in the message header information of the service data is reduced, so that the service type detection efficiency is improved.
