Embodiment 1
[0051] like Figure 1 to Figure 3 As shown, what the present invention discloses is a kind of reconnaissance GPS positioning method based on a composite event trigger mechanism, comprising:
[0052] Step S1, receiving the positioning data through the GPS signal receiving terminal installed on the positioned object, and extracting the first coordinate data g including longitude coordinate x and latitude coordinate y 1 (x, y), the first coordinate data g 1 (x, y) is equal to the update frequency of the longitude and latitude coordinates of the positioning data. For the civilian GPS data receiving end, the first coordinate data g 1 (x, y) is equivalent to having an update frequency of latitude and longitude coordinates of 10 Hz; wherein, the positioning data may be two-dimensional GPS data including only latitude and longitude coordinates, or multi-dimensional GPS data including at least latitude and longitude coordinates.
[0053] Step S2, data optimization based on the compos...
Embodiment approach
[0063] In the first trigger condition, the way of judging the motion state is:
[0064] Monitor the motion speed of the positioned object through the auxiliary sensor, if the motion speed is within the time interval [T2 i-1 , T1 i ] is higher than the preset motion speed threshold, then it is determined that the positioned object is within the first coordinate data g 1 The current latitude and longitude coordinate value update time T1 of (x, y) i In a non-stationary state of motion; among them, the last update time of latitude and longitude coordinates is T2 i-1 is the second coordinate data g 2 (x, y) at the update time T1 of the current latitude and longitude coordinates i At the latest previous update of the latitude and longitude coordinates, the movement speed threshold is zero or a speed value close to zero.
[0065] Wherein, the auxiliary sensor can be an existing sensor such as an IMU or an electromagnetic speed sensor that can sense the movement of the positioned...
Embodiment 3
[0069] On the basis of the above-mentioned embodiment 1 or embodiment 2, this embodiment 3 also adopts the following preferred implementation modes:
[0070] In the first trigger condition, the way of judging valid data is:
[0071] If satisfied||g 1 (x,y,i)-g 2 (x, y, i-1)||3 (x,y,k)-g 3 (x, y, k-1)||this judgment condition, then judge the first coordinate data g 1 (x, y) The latitude and longitude coordinate value of this update is valid data that conforms to the actual motion characteristics of the positioned object; where, g 1 (x, y, i) represents the first coordinate data g 1 (x, y) at the time T1 when the latitude and longitude coordinates are updated i The latitude and longitude coordinate value, g 2 (x, y, i-1) represents the second coordinate data g 2 (x, y) at the time T2 of the last update of the latitude and longitude coordinates i-1 The latitude and longitude coordinate value of the weight n ranges from 3.5≤n≤7, g 3 (x, y, k) represents the third coordina...
