I've purchased a GPS module VK2828U7G5LF. It is based on UBX-M8030-KT chip, antenna and UART interface.
I've used USB TTL serial converter to connect my GPS module to PC. The manufacturer of UBX-M8030-KT chip provides free software u-blox u-center to test and configure GPS module. It is very useful tool to start working with GPS module and debug protocol and controller behavior..
u-blox provides AssistNow feature for better precision. It is quite important for ant road related application. I've registered on u-blox site and got the token to use this technology. I've entered the token in the application and got data from the server. But my attempts to load this data into GPS Module failed. I suspect it may be a limitation of my GPS module.
Connecting GPS Module to Arduino
There is a lot of code samples for this GPS module built for Arduino platform.
