Utilizing the existing processing power

Fastrax Software GNSS performs all GNSS functionalities in software on an already existing CPU of the device, without the need of any GNSS specific IC. This includes signal correlation, - acquisition and – tracking as well as pseudorange calculations, navigation and final output.

Fastrax Software GNSS is a highly flexible receiver using an RF Front-end as the only GNSS specific component. With a suitable RF front-end any existing and future GNSS system can be utilized for navigation. This kind of receiver architecture is also the most cost-efficient compared to any other GNSS receiver implementation. A software receiver can also be used to implement receiver architectures that are not possible with a traditional hardware based solution and therefore e.g. extreme sensitivity or lowest possible power consumption can be achieved. Close R&D cooperation with the customer during early stage of the project ensures that choice of RF Front-End and CPU as well as Software GNSS design is optimized for the customers' particular application and needs.

Technology availability

Fastrax's software based GPS technology is available as two versions:

1) Fastrax Software GPS
- For high-end application processors

2) Fastrax Accelerated Software GPS
- For low- and mid-end application processors with reduced MIPS resources

Fastrax's solution is targeting high volume consumer electronic devices, such as cell phones, E911 phones, laptop computers, digital cameras and Personal Navigation Devices.
