Software GPSSW GNSS benefits per target marketCellular (Handset) market:- New requirements for performance as well as additionalGNSS systems are often limited by hardware.With Software GNSS, the flexibility of the solutionwill solve this issue.- Low BOM cost is a standard requirement; the bestoption to minimize component cost is to utilizealready existing hardware capabilities. This can beachieved by true SW GNSS integration.- Size of required additional components is minimalTablets and portable computers:- Low component cost. When properly planned, theexisting CPU power is sufficient for continuous navigationutilizing SW GNSS.- Size of the GNSS solution is critical, it’s always beneficialto get rid of extra HW or components.- Multi-GNSS support will become de facto standard.Software is the optimal way to achieve this.- Narrowband EMI is a challenge in almost every platform,with SW GNSS the interference can easily beremoved. Fastrax design support can also help insuppressing wideband EMI.Timing and synchronization:- Accuracy of timing is critical with most systems. SWGNSS with 1PPS accuracy of 15 ns will make theSW GNSS an unbeatable solution for any synchronizationsystem.- Utilizing existing hardware, SW GNSS can be usedfor example in femtocell systems. There is no needto add a special GNSS receiver module with costlyVCOCXO and other components, instead a lowcostVCTCXO can be used, saving remarkably onthe cost.Digital cameras:- The most critical requirements for picture positioningin camera are TTFF as well as power consumption.- Using Tag & Locate with SW GNSS post-processingcapability, the signals (noise) can be recorded at themoment of pressing the shoot-button, minimizingthe power consumption as well as the typical timefor TTFF. The recorded Tag can be stored simply onthe memory card like the photo. Photos are thenuploaded to a computer where the position can becalculated, using the Fastrax SW GNSS.- Price of SW GNSS in camera application is minimalcompared to a built-in GNSS receiver.FFT Acq Correlator API iCore TM SW Corrsmartpositioning11/201123
