Fastrax Software GNSSWhat is Fastrax Software GNSS?Fastrax Software GNSS performs all GNSS functionalitiesin software on an already existing CPU of thedevice, without the need of any GNSS specific IC. Thisincludes signal correlation, - acquisition and – trackingas well as pseudorange calculations, navigation andfinal output.Fastrax Software GNSS is a highly flexible receiver usingan RF Front-end as the only GNSS specific component.With a suitable RF front-end any existing and futureGNSS system can be utilized for navigation. This kindof receiver architecture is also the most cost-efficientcompared to any other GNSS receiver implementation.A software receiver can also be used to implementreceiver architectures that are not possible with atraditional hardware based solution and therefore e.g.extreme sensitivity or lowest possible power consumptioncan be achieved. Close R&D cooperation with thecustomer during early stage of the project ensures thatchoice of RF Front-End and CPU as well as SoftwareGNSS design is optimized for the customers’ particularapplication and needs.Key Features:Lowest cost GNSS solutionHuge cost saving through softwareupgrades instead of HW re-designsLowest possible energy/fix required.Easy to optimize and adjust to availableresources and signal availabilityFlexibility for customizationsSupport for GNSS, Software upgradeableto new GNSS systemsNon real time requirement for signalprocessingBenefits with Fastrax Software GNSSCost & Flexibility – Cost is significantly reducedas required silicon area is minimized in comparison toany other available GNSS solution.Flexibility is unique with Fastrax Software GNSS. Byusing latest available radios with Fastrax SoftwareGNSS things become really interesting. The receiversupports GPS today but can be configured to receiveother GNSS signals in the future as well. A multibandGNSS receiver can thus be implemented with a fractionof the cost of existing conventional multiband receivers.Low power consumption – Another truly uniquefeature with Fastrax Software GNSS is that the powerconsumption is typically 30mJ/fix, which is equivalentof more than 60.000 fixes from a single coin cell battery.This is achievable as Fastrax Software GNSS receiverneeds only to be on as long as the GNSS signal isreceived. In urban canyons 100ms is typically enoughfor good performance and in areas with good visibility itcan be even shorter.Record Breaking Sensitivity – Fastrax SoftwareGNSS enables also integration times far longerthan conventional receivers and thus record breakingacquisition sensitivities can be achieved. The softwarearchitecture is also very flexible in terms of number ofchannels and number of correlator fingers used, whichcan be adjusted and optimized according to applicationspecific requirements. With Fastrax Software GNSS it isadditionally straightforward to implement multipath mitigationand to detect and eliminate interference of CW(continuous wave) type of signals.22 www.fastraxgps.com
