Area, then mobile terminal continue to operate in the first alignment system；If mobile terminal is in certain types of area, execution step
S220.For example, the first alignment system is GPS positioning system, and the second alignment system is BEI-DOU position system, particular type area bag
Include ocean area, mobile terminal is currently operating in GPS positioning system, then judge whether mobile terminal locates Yu Haiyang area；If sentencing
Disconnected mobile terminal is not in ocean area, then continue to operate in GPS positioning system.
Step S220, if mobile terminal is in particular type area, judges whether the first alignment system meets use.
If the first alignment system meets using, mobile terminal continues to operate in the first alignment system, if the first positioning system
System can not meet use, then execution step S230.As it was previously stated, can be according to the corresponding satellite-signal of described first alignment system
Whether whether signal to noise ratio be in off-lying sea or remote mountains area less than the first predetermined threshold or described mobile terminal, determines the first positioning
Whether system meets use.For example, GPS positioning system off-lying sea area be likely to occur satellite-signal faint it is impossible to be accurately positioned
Situation, it is more accurate that BEI-DOU position system at sea carries out positioning.Therefore, if mobile terminal be in off-lying sea area it is determined that
GPS positioning system can not meet use, and execution step S230.If GPS positioning system meets using, mobile eventually without switching
The alignment system of end work.
Step S230, if the first alignment system can not meet use, alignment system that mobile terminal is worked is by first
Alignment system switches to the second alignment system.
Use the example above, if GPS positioning system can not meet use, by the alignment system of mobile terminal work at present by
GPS positioning system switches to BEI-DOU position system.
