如何使用python dronekit实现“向左/向右/向前/向后”？

from dronekit import connect, VehicleMode, LocationGlobalRelative

# 连接到无人机
vehicle = connect('udp:127.0.0.1:14550', wait_ready=True)

# 向左飞行
def fly_left(distance):
    current_location = vehicle.location.global_relative_frame
    target_location = LocationGlobalRelative(current_location.lat, current_location.lon - distance, current_location.alt)
    vehicle.simple_goto(target_location)

# 向右飞行
def fly_right(distance):
    current_location = vehicle.location.global_relative_frame
    target_location = LocationGlobalRelative(current_location.lat, current_location.lon + distance, current_location.alt)
    vehicle.simple_goto(target_location)

# 向前飞行
def fly_forward(distance):
    current_location = vehicle.location.global_relative_frame
    target_location = LocationGlobalRelative(current_location.lat + distance, current_location.lon, current_location.alt)
    vehicle.simple_goto(target_location)

# 向后飞行
def fly_backward(distance):
    current_location = vehicle.location.global_relative_frame
    target_location = LocationGlobalRelative(current_location.lat - distance, current_location.lon, current_location.alt)
    vehicle.simple_goto(target_location)

# 设置飞行模式为GUIDED
vehicle.mode = VehicleMode("GUIDED")

# 飞行指令
fly_left(10)  # 向左飞行10米
fly_right(10)  # 向右飞行10米
fly_forward(10)  # 向前飞行10米
fly_backward(10)  # 向后飞行10米

# 断开连接
vehicle.close()
