On November 7, 2020, NiceRF will conduct system training for new products SW-GPS01 and GPS002. The participants include our company’s business and promotion personnel. The purpose is to allow employees to understand new products more quickly and better Customer service, expand related business.
In the training of SW-GPS01 and GPS002, our hardware engineer, Mr. Pan, will give lectures and training. Mr. Pan is mainly responsible for explaining the functions and characteristics of SW-GPS01 and GPS002, communication protocol, starting method, external interface, and performance. The following is a brief introduction to the training content of the SW-GPS01 module and GPS002 antenna by the editor of NiceRF:
GPS positioning module SW-GPS01
SW-GPS01 module is a positioning module that supports BDS B1/GPS L1/GLONASS L1 frequency point (two out of three) dual-mode navigation. It provides high sensitivity, high positioning accuracy, low power consumption and low cost positioning and navigation solutions for the manufacture of navigation and positioning terminal products such as vehicle, shipborne, handheld and wearable.
1. After the GPS module is started, it takes a period of time to locate, and the search time varies with the start mode.
2. Cold start
The module is started for the first time without any satellite data, and it takes 1-10 minutes to locate.
3. Hot start
The satellite information has been saved, temporarily turn off the power to sleep, use the backup power supply, restart within two hours, and locate in a few seconds.
4. Warm start
Using backup power, the shutdown time is more than 2 hours, and within 8 hours, the module saves satellite information but the time is not strong, and the startup time is between cold start and hot start.
1. Serial port
Use the international standard NMEA-0183 protocol
NMEA 0183 is a standard format developed by the National Marine Electronics Association for marine electronic equipment. It has also become a unified RTCM (Radio Technical Commission for Maritime services) standard protocol for GPS navigation equipment.
You can also use the international standard IIC communication protocol, refer to the document "SW-GPS01 Module I2C Interface Description"
