Introduction to the GPS software of G1 and how to enable the GPS module
We still use G1 as an example. G1 is equipped with a hardware GPS chip. However, most of the available GPS maps in G1 currently do not support offline image libraries, that is to say, you must ens
Simple Analysis of android Qemu GPS module
The gps module of Android is gps. default. so on the system/lib/hw/directory. Generally, the mobile phone that provides the gps function should implement the interaction between this
Research and development of GPS products is the choice of GPS module or chip scheme. The market above the GPS program, how to choose it. I have been in contact with GPS design for several years, and now the experience of GPS proje

NMEA0183 protocol for GPS module programmingBy drizzle QQ: 253786989
NMEA 0183 is a standard format developed by National Marine Electronics Association for Marine electronic devices. Now it has become the standard RTCM (Radio Technical Commission for Maritime services) protocol for GPS navigation devices.

These timing services provide a variety of data formats, such a

However, the customer recently said that the GPS of the mobile phone is not accurate enough, so he learned about the two parameters in the function signature from the Google developer website. If there is any inac

At present, many so-called internet companies have to engage in GPS positioning attendance clock, the current customer units also require all manufacturers to clock the GPS software. In addition to the company's fingerprint clocking out, but also to hit the customer's card. Since it is geo-positioning, the Android platform has been tested before the use of fake GPS
