How To Choose SKYLAB GPS Module?

GPS positioning is an important technology for IoT. With the development of smart cities, there is more demand for accurate outdoor positioning technology. In this article, I will introduce the classification and characteristics of SKYLAB GPS Modules.

SKYLAB GPS modules are divided into four categories according to the different applications. A single GPS module refers to a GPS module without an antenna. GPS Timing Module supports timing function.

Antenna-integrated GPS module refers to the incorporation of a ceramic antenna. It is an antenna-integrated product developed based on a single GPS module, and users do not need to configure the antenna separately. G-mouse refers to the GPS antenna integration based on the addition of the shell.

(1) Single GPS positioning module

SKYLAB single GPS module has two series, A series single GPS module mainly includes SKG09A and SKG12A, etc. BL series single GPS module mainly includes SKG09BL and SKG12BL, etc. The biggest difference between the two series of single GPS modules is that the GPS chips are different.

The A series single GPS module adopts a dedicated high-performance architecture. It has a built-in high-precision TCXO and a low-noise amplifier. The module has ultra-high sensitivity and extremely short capture positioning time. It can meet the positioning needs of vehicle navigation, car recorder, and wearable devices.

A series of GPS modules SKG09A and SKG12A are based on the MT3339 chip. It has the features of low power consumption, high integration, and programmable. In addition, it supports antenna detection, time pulse, AGPS, EASY, and data logging functions.

BL series GPS modules SKG09BL, and SKG12BL are developed based on the MT3337 chip side. It supports configuration pins, time pulses, AGPS, and EASY functions. But it does not support programming, antenna detection, and data logging.

BL series GPS module adopts advanced RF architecture and interference suppression, so it has higher performance. And it has the advantage of low cost.

(2) Antenna-integrated GPS module

Antenna-integrated GPS modules mainly include SKM61, SKM81B, SKM82, SKM86, and so on. It adopts multiple package sizes to meet the upgrade and replacement of different applications. The module antenna is highly integrated, so customers can finish sample testing faster.

(3) G-mouse GPS Module

SKYLAB G-mouse GPS modules mainly include SKM51 and SKM55. This series of modules have built-in LNA and SAW filters and have good RF performance. It combines the performance of the GPS module and GPA antenna perfectly. The modules have a multi-interface design, including Micro-Fit 3.0, USB, DB9, Audio Audio, and JST interface.

In addition, the length of the module antenna can be customized according to the application scenario. It can meet in-vehicle positioning applications such as buses and cabs.

(4) GPS Timing Module

SKYLAB GPS timing module AT series mainly includes SKG12AT. it adopts special high-performance architecture, built-in high precision TCXO, and low noise amplifier. SKG12AT is developed based on the MT3339 chip solution. It can meet the needs of the base station, power, communication, and traffic timing.

SKYLAB's GPS module can realize the functions of positioning, navigation, and timing. According to the function of the GPS module, the GPS module is divided into three categories, including positioning GPS module, navigation GPS module, and timing GPS module.

(1) Positioning GPS module

• Low-power GPS modules can be used in the field of intelligent wearable devices. For example, outdoor watches, children's watches, elderly watches, and pet locators, etc.

• GPS module is applied in smartphones, tablet PCs, PNDs, DVRs, etc. that use GPS services.

• GPS module is applied in the field of various portable devices such as industrial PDA, handheld, law enforcement instrument, etc.

• GPS module is applied in the field of security such as network camera, street light, etc.

• GPS module is applied in the field of vehicle positioning terminal and other equipment.

• GPS module is applied in area measurement and distance measurement and other mapping equipment.

• GPS module is applied in the field of unmanned aircraft. It is used for the accurate positioning of drones.

(2) Navigation GPS module

• Car navigation such as school buses, buses, logistics vehicles, and cab navigation services.

• Outdoor handheld navigation, such as power grids, base stations, geological surveys, donkeys, and other navigation servers.

(3) Timing GPS module

• Satellite synchronous timing is mostly used in electric power, finance, communication, and base station synchronous timing.

• Traffic timing is mostly used for highway-induced light and traffic signal accurate timing.
