Abstract

The invention provides an electricity-saving satellite positioning method. The electricity-saving satellite positioning method comprises the following steps that (1) a positioning unit and a timing unit are provided; (2) the positioning unit is started to enter a positioning mode, so that positioning is started, and the timing unit is started; (3) when the positioning unit successfully conducts positioning or the time of the positioning mode of the timing unit is up, the positioning unit is switched to an electricity-saving mode from the positioning mode; (4) after the positioning unit enters the electricity-saving mode, the positioning unit stops positioning, and when the set time of the electrify-saving mode of the timing unit is up, the positioning unit is switched to the positioning mode from the electricity-saving mode, wherein the time of the positioning mode is shorter than the set time of the electricity-saving mode; (5) after the positioning unit enters the positioning mode, the step (3) is executed again. By the adoption of the electricity-saving satellite positioning method, a provided satellite positioning module works in the positioning state within a short time, and most of the time, the satellite positioning module works in the electricity-saving state; in addition, switching between the electricity-saving mode and the positioning mode is controlled through interrupt signals, control is orderly and not prone to errors, and long-term periodical positioning is facilitated.

Description

technical field

[0001] The invention relates to satellite positioning technology, in particular to a power-saving positioning method for a satellite positioning terminal and a power-saving satellite positioning terminal. Background technique

[0002] Usually, the power consumption of a satellite positioning module during positioning is hundreds or even thousands of times that of the module in power-saving mode. For example, the average current of a Beidou module is 60mA, while the average current in power-saving mode is 20uA. The power consumption differs by a factor of 3000.

[0003] At present, the handheld satellite positioning terminal on the market, when uninterrupted positioning information is required, its working mode is continuous positioning, so that the satellite positioning module always works, because the satellite positioning module consumes a lot of power during positioning, so it will seriously affect the handheld terminal. The normal working hours of the s...
