Qualcomm has planned to provide support for 27 Russian GLONASS navigation satellites on the mid-end models S2 and S3 of its Snapdragon mobile processor. Previously, it supported GPS communication with 24 satellites.
Smartphones usually require at least 4 satellites for complete and complete navigation work, and the positioning of the GLONASS satellite can make star search faster (because the opportunity is greater) and more accurate, and the accuracy is expected to be within 6 feet. Another benefit is that more satellites can bring lower power consumption, and mobile phones can lock satellites without much power.
The application of outdoor display screen is made of LED module splicing, and the screen size is customized according to the size of outdoor module required by customers. The screen body of various application occasions required by customers, such as outdoor large screen, vehicle screen, door screen, traffic guidance screen, etc. All display contents are set according to customer requirements.
LED outdoor module classification: single color, only one color module can be displayed, such as single red, light green, single white, single blue, etc.

2. Good waterproof performance: the waterproof performance of the screen is IP65, so no matter what kind of environment, it can meet the use requirements.
3. Diversity of customization: according to customer requirements, customize different shapes to meet personalized needs
4. Module installation: each model of product has its corresponding size, so the size of modular installation can be adjusted at will, and maintenance is simple. The removal and installation of single block will not affect the use of the whole screen.
Structure of outdoor module: outdoor module consists of outdoor high brightness LED lamp beads, waterproof glue, PCB, IC and resistance capacitance electronic components, bottom shell and mask. The above can be customized according to the customer's requirements, matching according to the customer's requirements, the use voltage is generally low voltage 5V or 3.8V, etc.
Precautions: during the installation of the product, pay attention to collision at the corners, module transportation, and collision between LED modules. Connect the power supply voltage. Avoid damage.
