GPS Architecture

N/APS architecture is specifically developed for power-sensitive mobile information devices such as laptops, PDAs, digital cameras, smart phones, pagers and automobile navigation systems. The architecture allows high-volume manufacturers of consumer products to add GPS location with minimal impact on the device's size or battery life.

This architecture offers low power consumption, requiring 1/3 the power of most receivers (30-50 milliwatts at 3.3 volts when updating positions every second), FirstGPS is ideal for power-sensitive applications. For devices that only need location-on-demand, several sleep and low-power modes allow for further power savings and longer battery life.

It is a host-based architecture that allows flexible integration of GPS with other real-time software tasks. Without burdening the other applications running on the mobile device, FirstGPS leverages the host microprocessor (CPU) and memory to calculate the GPS position, velocity and time solutions. This architecture, which is microprocessor and real-time operating system (RTOS) independent, eliminates redundant CPUs and memory thereby reducing overall component count and product cost.
