What is Fastrax Software GNSS?
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.
Benefits with Fastrax Software GNSS
Cost & Flexibility
Cost is significantly reduced as required silicon area is minimized in comparison to any other available GNSS solution.
Flexibility is unique with Fastrax Software GNSS. By using latest available radios with Fastrax Software GNSS makes things really interesting. The receiver supports GNSS today but can be configured to receiver other GNSS signals in the future as well. A multiband GNSS receiver can thus be implemented with a fraction of the cost of existing conventional multiband receivers.
Low power consumption
Another truly unique feature with Fastrax Software GNSS is that the power consumption is typically 30mJ/fix, which is equivalent of more than 60.000 fixes from a single coin cell battery. This is achievable as Fastrax Software GNSS receiver needs only to be on as long as the GNSS signal is received. In urban canyons 100ms is typically enough for good performance and in areas with good visibility it can be even shorter.
Record Breaking Sensitivity
Fastrax Software GNSS enables also integration times far longer than conventional receivers and thus record breaking acquisition sensitivities can be achieved. The software architecture is also very flexible in terms of number of channels and number of correlator fingers used, which can be adjusted and optimized according to application specific requirements. With Fastrax Software GNSS it is additionally straightforward to implement multipath mitigation and to detect and eliminate interference of CW (continuous wave) type of signals.
