How to optimize consumer GPS systems within the electronic equipment
| oad of the technology can be used as appropriate trade-off between sensitivity and power consumption. Although the device is also licensed for the main baseband processor cycles, but will have to pay a price in power consumption. Very important in battery life in handheld devices, if the positioning accuracy of deliberately maintained at a reasonable level, the device can make more than the main processor in standby mode to save power. Software-based baseband processor, one of the main advantages is the flexibility in the device to achieve a variety of innovative energy-saving technologies (see supplementary material: a variety of innovative energy-saving technology). This is because different parts of the system can be controlled separately, and without the need for costly re-tape (re-spin), can the existing design
Architecture Flexibility Baseband processor using software provided the flexibility, but also allows developers to apply for a variety of specific cost, power and performance indicators to adjust the process and power technology. Because of these differences by the software to meet the requirements, so just a hardware radio receiver can respond to many different applications, so as to OEM manufacturers to provide better economies of scale. In contrast, the use of a traditional hardware-based GNSS modules, developers will have to face difficulties: either maintain the several RF hardware design; or maintain an energy common to a variety of applications, but also on the performance of each application not the most optimized hardware design. In addition, when a special signal or environmental conditions for the new algorithm available, you can use the software to achieve, which not only extended the period of use the wireless receiver architecture, but also continue to improve various properties, such as accuracy and tracking sensitivity. The flexibility of software-based GNSS are more hardware-only de |
