[0037] At present, when satellite communication watches acquire satellite signals outdoors, they need to adjust the direction and tilt angle of the watch so that the antenna inside the watch is aligned with the satellite, thereby realizing data transmission and interaction. In the existing technology, users need to take off their watches and hold them to adjust the direction and tilt angle of the watch, or they need to move their arms and rotate their wrists, which is a large movement range, resulting in inconvenience and poor user experience.

[0047] The following introduces a satellite communication watch alignment method provided in an embodiment of the present application.

[0048] See also Figure 4 , Figure 4 The present invention provides a flowchart of a satellite communication watch alignment method, which is applicable to Figure 1 The controller 120 in the antenna control system 100 shown includes an antenna 110, a controller 120 and an antenna rotation module 130. The antenna 110 is in communication connection with the controller 120, and the controller 120 is in communication connection with the antenna rotation module 130. The controller 120 may be a controller or a controller cluster composed of several controllers; as shown in the figure, the method includes the following steps:

[0049] Step S401, determining a target satellite according to satellite operation information and current positioning information.

[0050] Before determining the target satellite according to the satellite operation information and the current positioning information, the method further includes: controlling the antenna rotation module to rotate until the antenna rotation module drives the antenna to point to the south.

[0051] The satellite operation information is ephemeris information, which records various parameters of the satellite operation, such as time, coordinates, and speed.

[0052] Among them, the current positioning information is the longitude and latitude of the watch.

[0053] In a possible embodiment, determining the target satellite based on satellite operation information and current positioning information includes: determining current satellite position information corresponding to multiple satellites based on the satellite operation information; and determining the target satellite based on the current satellite position information and the current positioning information corresponding to each satellite in the multiple satellites.

[0054] The current satellite position information includes the latitude and longitude of the satellite.

[0055] Among them, the current satellite position information corresponding to multiple satellites is determined according to the satellite operation information. For example, it can be: multiple satellites include satellite A, and the current time is 10:00 on May 1, 2024. Then, the coordinates of multiple satellites at 10:00 on May 1, 2024 are queried in the satellite operation information, and the current satellite position information corresponding to satellite A is the longitude and latitude of satellite A at 10:00 on May 1, 2024.

[0056] Among them, the target satellite is determined according to the current satellite position information and the current positioning information corresponding to each satellite of the multiple satellites, and specifically, the distance of each satellite from the watch is determined according to the current satellite position information and the current positioning information corresponding to each satellite; and the satellite with the shortest distance from the watch is determined as the target satellite.

[0057] It can be seen that in this example, the current satellite position information corresponding to multiple satellites is determined according to the satellite operation information, and then the target satellite is determined according to the current satellite position information corresponding to each satellite and the current positioning information of the watch, so as to determine the first rotation angle and the second rotation angle for the target satellite, and then generate a first rotation instruction according to the first rotation angle to let the antenna rotation module rotate according to the first rotation instruction, and generate a first reminder message to remind the user to turn the wrist according to the second rotation angle, so that the user does not need to move his arm, but only needs to turn his wrist to align the satellite, thereby sending a short message to the target satellite, reducing the user's movement range during the alignment process, thereby improving convenience and user experience.

[0058] Step S402: determining a first rotation angle and a second rotation angle according to the target satellite and the current positioning information.

[0059] The first rotation angle is used to indicate the angle at which the antenna needs to be rotated in the horizontal direction to align with the target satellite.

[0060] In a possible embodiment, the first rotation angle is determined by the following steps: obtaining a preset first model and a magnetic declination calculation model; importing the current satellite position information and the current positioning information corresponding to the target satellite into the first model to obtain the first theoretical angle; importing the current positioning information into the magnetic declination calculation model to obtain the target magnetic declination; determining the first target angle based on the first theoretical angle and the target magnetic declination; obtaining the current beam center of the antenna; and determining the first rotation angle based on the current beam center and the first target angle.

[0061] The preset first model may be, for example, the following formula:

[0062] ;

[0063] Among them, AZ is the first theoretical angle, is the longitude of the satellite, The longitude of the watch, The latitude of the watch.

[0064] The first theoretical angle is used to indicate the angle at which the antenna needs to be pointed in the horizontal direction based on the true north.

[0065] Since the first theoretical angle obtained according to the first model is based on the true north, it is necessary to calculate the magnetic declination to correct the first theoretical angle AZ, so as to obtain the first target angle AZ1 based on the magnetic north.

[0066] The target magnetic declination is used to indicate the angle between magnetic north and true north.

[0067] The magnetic north is accurately measured by a geomagnetic sensor in the watch, which is in communication with the controller.

[0068] Among them, the magnetic declination calculation model is a model for calculating the magnetic declination determined by using the geographic data released by NOAA as training data. The current positioning information is imported into the magnetic declination calculation model, and the output result obtained is the target magnetic declination.

[0069] The first target angle is used to indicate the angle at which the antenna needs to point in the horizontal direction based on the magnetic north.

[0070] Wherein, determining the first target angle according to the first theoretical angle and the target magnetic declination includes: when the target magnetic declination is greater than 0, determining the first target angle as the difference between the first theoretical angle and the target magnetic declination; when the target magnetic declination is less than 0, determining the first target angle as the sum of the first theoretical angle and the target magnetic declination.

[0071] It can be seen that in this example, the first theoretical angle is determined according to the current satellite position information corresponding to the target satellite and the current positioning information of the watch, and the first theoretical angle is corrected by the target magnetic declination determined according to the current positioning information to obtain the first target angle, so that the first rotation angle indicating the angle that the antenna needs to rotate in the horizontal direction is determined according to the first target angle and the current beam center of the antenna, and then a first rotation instruction is generated according to the first rotation angle to allow the antenna rotation module to rotate according to the first rotation instruction, so that the user does not need to move his arm, but only needs to rotate his wrist to align the satellite, thereby sending a short message to the target satellite, reducing the user's movement amplitude during the alignment process, thereby improving convenience and user experience.

[0072] In a possible embodiment, determining the first rotation angle based on the current beam center and the first target angle includes: determining the beam center direction of the antenna based on the current beam center; determining a first direction angle based on the beam center direction; and determining the first rotation angle based on the first direction angle and the first target angle.

[0073] The current beam center is the direction to which the beam center of the antenna points at the current moment.

[0074] Wherein, determining the beam center direction of the antenna according to the current beam center includes: determining the projection direction of the current beam center on the plane of the watch as the beam center direction.

[0075] The first direction angle is used to indicate the angle at which the antenna in the current watch points in the horizontal direction based on the magnetic north.

[0076] Wherein, determining the first direction angle according to the beam center direction includes: determining the angle between magnetic north and the beam center direction as the first direction angle AZ2.

[0077] The determining of the first rotation angle according to the first direction angle and the first target angle includes: determining a difference between the first target angle AZ1 and the first direction angle AZ2 as the first rotation angle ΔAZ.

[0078] It can be seen that in this example, the beam center direction is determined according to the direction pointed by the beam center of the antenna at the current moment, and then the first direction angle of the antenna in the horizontal direction relative to the magnetic north is determined according to the beam center direction, and then the first rotation angle is determined according to the first direction angle and the first target angle, so that a first rotation instruction is generated according to the first rotation angle, so that the antenna rotation module rotates according to the first rotation instruction, and then a first reminder message is generated according to the second rotation angle, reminding the user to turn his wrist to align with the target satellite, so that the user does not need to move his arm, but only needs to turn his wrist to align with the target satellite, thereby sending a short message to the target satellite, reducing the user's movement amplitude during the alignment process, thereby improving convenience and user experience.

[0079] In a possible embodiment, the second rotation angle is determined by the following steps: obtaining a preset second model; importing the current satellite position information and the current positioning information corresponding to the target satellite into the second model to obtain the second target angle; obtaining the antenna beam range of the antenna; and determining the second rotation angle based on the antenna beam range and the second target angle.

[0080] The second rotation angle is used to indicate the angle at which the antenna needs to be rotated in the vertical direction to align with the target satellite.

[0081] The preset second model may be, for example, the following formula:

[0082] EL= ;

[0083] Where EL is the second target angle, is the longitude of the satellite, The longitude of the watch, The latitude of the watch.

[0084] The second target angle is used to indicate the angle at which the antenna needs to point in the vertical direction based on the ground plane.

[0085] It can be seen that in this example, the second target angle is determined according to the current satellite position information corresponding to the target satellite and the current positioning information of the watch, and the second rotation angle is determined according to the current beam center, antenna beam range and the second target table, so that the first reminder information to remind the user to turn his wrist is generated according to the second rotation angle, so that the user does not need to move his arm, but only needs to turn his wrist to align the satellite, thereby sending a short message to the target satellite, reducing the user's movement amplitude during the aligning process, thereby improving convenience and user experience.

[0086] In a possible embodiment, determining the second rotation angle according to the antenna beam range and the second target angle includes: determining the first angle of the antenna; determining the second angle of the antenna according to the antenna beam range; determining the second direction angle according to the antenna beam range, the first angle and the second angle; determining the second rotation angle according to the second direction angle and the second target angle.

[0087] The first angle is the angle between the plane of the antenna and the ground plane.

[0088] The angle of the plane of the antenna relative to the beam center of the antenna is a preset angle.

[0089] The second angle is the angle between the antenna beam range and the plane of the watch.

[0090] The antenna beam range is used to characterize the width of the main lobe of the antenna, that is, the angle.

[0091] The second direction angle is used to indicate the angle at which the center of the antenna beam of the antenna in the current watch points in the vertical direction with the ground plane as the standard.

[0092] The step of determining the second direction angle according to the antenna beam range, the first angle and the second angle comprises: generating a satellite alignment side view according to the antenna beam range, the first angle and the second angle; and determining the second direction angle according to the satellite alignment side view.

[0093] Among them, see Figure 5 , Figure 5 1 is a schematic diagram of a method for aligning a satellite communication watch provided in an embodiment of the present application. Figure 5 As shown, α is the first angle, β is the antenna beam range, γ is the second angle, X is the preset angle, and EL1 is the second direction angle.

[0094] The determining of the second rotation angle according to the second direction angle and the second target angle includes: determining the difference between the second target angle EL and the second direction angle EL1 as the second rotation angle ΔEL.

[0095] It can be seen that in this example, the first angle of the antenna surface relative to the ground plane is first determined, and then the second angle of the antenna beam range relative to the plane of the watch is determined according to the antenna beam range, so that the second direction angle of the antenna beam center of the antenna relative to the ground plane in the vertical direction is determined according to the antenna beam range, the first angle and the second angle, and then the second rotation angle is determined according to the second direction angle and the second target angle, so that the first reminder information to remind the user to turn the wrist is generated according to the second rotation angle, so that the user does not need to move his arm, but only needs to turn his wrist to align the satellite, thereby sending a short message to the target satellite, reducing the user's movement amplitude during the alignment process, thereby improving convenience and user experience.

[0096] Step S403: generating a first rotation instruction according to the first rotation angle.

[0097] The first rotation instruction is used to instruct the antenna rotation module to rotate itself, thereby driving the antenna to rotate in the horizontal direction so that the rotation angle of the antenna satisfies the first rotation angle.

[0098] In a possible embodiment, generating a first rotation instruction based on the first rotation angle includes: obtaining a preset error threshold; determining a rotation direction of the antenna rotation module based on the error threshold and the first rotation angle; and generating the first rotation instruction based on the rotation direction and the first rotation angle.

[0099] The error threshold may be Δ0, for example.

[0100] Wherein, determining the rotation direction of the antenna rotation module according to the error threshold and the first rotation angle includes: when the first rotation angle is greater than the error threshold, determining that the rotation direction of the antenna rotation module is clockwise; when the first rotation angle is less than the negative number of the error threshold, determining that the rotation direction of the antenna rotation module is counterclockwise.

[0101] Among them, there is a deviation between the rotation angle of the antenna rotation module itself and the rotation angle of the antenna. For example, when the antenna rotation module itself rotates 30°, it drives the antenna to rotate 20°. The ratio of the rotation angle of the antenna rotation module itself to the rotation angle of the antenna is 3:2. At this time, the first rotation instruction is generated according to the rotation direction and the first rotation angle. Specifically, if the first rotation angle is 30° and the rotation direction is clockwise, the first rotation instruction instructs the antenna rotation module to rotate 45° clockwise.

[0102] Step S404: sending the first rotation instruction to the antenna rotation module, so that the antenna rotation module rotates the antenna according to the first rotation angle.

[0103] The antenna rotation module receives the first rotation instruction and executes the rotation instruction.

[0104] Step S405: Generate first reminder information according to the second rotation angle, where the first reminder information is used to remind the user to rotate the wrist according to the second rotation angle to align the antenna with the target satellite.

[0105] The generating of the first reminder information according to the second rotation angle includes: determining a wrist rotation direction according to the second rotation angle; and generating the first reminder information according to the wrist rotation direction and the second rotation angle.

[0106] Wherein, determining the wrist rotation direction according to the second rotation angle includes: when the first rotation angle is greater than 0, the wrist rotation direction is backward rotation; when the first rotation angle is less than 0, the wrist rotation direction is forward rotation.

[0107] The first reminder information is generated according to the wrist rotation direction and the second rotation angle. For example, if the wrist rotation direction is forward rotation and the second rotation angle is 30°, the first reminder information is "rotate your wrist forward 30°".

[0108] Step S406: When it is detected that the antenna is aligned with the target satellite, a target short message is sent to the target satellite.

[0109] Wherein, when it is detected that the antenna is aligned with the target satellite, before sending a target short message to the target satellite, the method further includes: updating the first rotation angle and the second rotation angle of the antenna in real time.

[0110] The antenna is aligned with the target satellite when a first rotation angle is between a negative number of the error threshold and the error threshold, and the second rotation angle is equal to 0.

[0111] It can be seen that in the present application, the controller determines the target satellite according to the satellite operation information and the current positioning information; determines the first rotation angle and the second rotation angle according to the target satellite and the current positioning information; generates the first rotation instruction according to the first rotation angle; sends the first rotation instruction to the antenna rotation module so that the antenna rotation module rotates the antenna according to the first rotation angle; generates the first reminder information according to the second rotation angle, and the first reminder information is used to remind the user to rotate the wrist according to the second rotation angle to align the antenna with the target satellite; when it is detected that the antenna is aligned with the target satellite, a target short message is sent to the target satellite. Since the first rotation angle and the second rotation angle are determined according to the current positioning information of the target satellite and the watch, the first rotation instruction is generated according to the first rotation angle, so that the antenna rotation module rotates according to the first rotation instruction, and then the first reminder information is generated according to the second rotation angle, reminding the user to rotate the wrist to align with the target satellite, so that the user does not need to move his arm, and only needs to rotate his wrist to align with the satellite, thereby sending a short message to the target satellite, reducing the user's movement range during the alignment process, thereby improving convenience and user experience.
