Positioning Module For Enterprise GPS Tracking Locator

The sensitivity of the GPS positioning signal is the primary requirement for a positioning module, depending on the industry, the positioning application scope should first meet the application requirements. Sensitivity indicators include tracking sensitivity, cold start sensitivity, etc. The tracking sensitivity and cold start sensitivity are generally -165dBm and -148dBm to meet application requirements.

For small business GPS fleet tracking, the time required for GPS positioning is divided into pure hardware cold start, pure hardware hot start, and pure hardware re-capture. Generally, the cold start time is a bit longer, reaching within 50 seconds, and the hot start and re-capture time should be less than 5 seconds.

The most important aspect of enterprise GPS tracking is accuracy, which includes horizontal, vertical, and velocity accuracy. This is equivalent to drawing a circle with the positioning module as the center and the vertical and horizontal distance as the radius. There are many factors that affect GPS positioning accuracy, not only the characteristics of the GPS positioning module, but also satellite clock difference, orbit difference, satellite quantity, and even solar radiation.

The GPS power consumption parameters of the vehicle tracking systems for small business are also important, as power consumption has a significant impact on the service life of the GPS positioning module. For GPS locators, the GPS positioning module must be selected with ultra-low power consumption to facilitate the battery and the GPS of the car, which have no impact on the positioning chip.

There are three common positioning modes for small business GPS fleet tracking, mainly high-precision mode, low-power mode, and device-only mode, among which the device-only mode is the most common and the most widely applicable. The vehicle locator manufacturers will introduce the characteristics of these modes, hoping to be helpful to you.

The high-precision mode of enterprise GPS tracking mainly uses network positioning and network positioning GPS positioning, and prefers to return to the highest precision positioning result, suitable for scenarios with high positioning accuracy requirements and no power consumption requirements.

The low-power mode of small business GPS fleet tracking mainly uses network positioning, such as Wi-Fi positioning and base station positioning GPS positioning module for positioning, so it is suitable for scenarios with high power consumption requirements.

The positioning mode of vehicle tracking device for small business mainly does not require network connection, and only uses the GPS positioning module for positioning, without supporting indoor environment positioning, suitable for outdoor positioning with high precision and strong dependence on the outdoor positioning GPS module positioning mode.
