Abstract
A satellite search method is applied to a mobile terminal. The satellite search method includes determining, based on location information of the mobile terminal, location information of an available satellite, and three-dimensional (3D) map information, whether a direct line of sight between the mobile terminal and the available satellite is blocked by an obstacle, and determining location information of a target area based on the 3D map information when the direct line of sight is blocked by the obstacle, where the target area includes a direct line of sight between the mobile terminal and the available satellite.
Claims20
A method implemented by a mobile terminal, wherein the method comprises:
- determining a target direction angle of a satellite based on a first location information of the mobile terminal and a second location information of the satellite, wherein the target direction angle includes a target azimuth angle and a target elevation angle;
- determining, based on a difference between a maximum gain direction angle of an antenna of the mobile terminal and the target direction angle, a first pose adjustment parameter for adjusting a pose of the mobile terminal, wherein the maximum gain direction angle is based on an antenna pattern of the antenna and the pose of the mobile antenna;
- outputting prompt information corresponding to the first pose adjustment parameter, wherein the prompt information instructs a user to adjust a pose of the mobile terminal;
- receiving adjustments of the user to the pose of the mobile terminal;
- and
- establishing a communication connection to the satellite when the difference between the maximum gain direction angle and the target direction angle is less than or equal to an angle threshold.
A mobile terminal comprising:
- a memory configured to store instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to cause the mobile terminal to:
- determine a target direction angle of a satellite based on a first location information of the mobile terminal and a second location information of the satellite, wherein the target direction angle includes a target azimuth angle and a target elevation angle;
- determine, based on a difference between a maximum gain direction angle of an antenna of the mobile terminal and the target direction angle, a first pose adjustment parameter for adjusting a pose of the mobile terminal wherein the maximum gain direction angle is based on an antenna pattern of the antenna and the pose of the mobile antenna;
- output prompt information corresponding to the first pose adjustment parameter, wherein the prompt information instructs a user to adjust a pose of the mobile terminal;
- receiving adjustments of the user to the pose of the mobile terminal;
- and
- establish a communication connection to the satellite when the difference between the maximum gain direction angle and the target direction angle is less than or equal to the angle threshold.
A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable storage medium and that, when executed by one or more processors, cause a mobile terminal to:
- determine a target direction angle of a satellite based on a first location information of the mobile terminal and a second location information of the satellite, wherein the target direction angle includes a target azimuth angle and a target elevation angle;
- determine, based on a difference between a maximum gain direction angle of an antenna of the mobile terminal and the target direction angle, a first pose adjustment parameter for adjusting a pose of the mobile terminal wherein the maximum gain direction angle is based on an antenna pattern of the antenna and the pose of the mobile antenna;
- output prompt information corresponding to the pose adjustment parameter, wherein the prompt information instructs a user to adjust a pose of the mobile terminal;
- receive adjustments of the user to the pose of the mobile terminal;
- and
- establish a communication connection to the satellite when the difference between the maximum gain direction angle and the target direction angle is less than or equal to an angle threshold.
