Receiver RequirementsShortest TTFFCustomers do not care about channels, correlators, Ephemeris (extended or not) they want a fix NOW

Highest sensitivityFix under all conditions no worries about an antenna

Lowest Power consumptionWe mainly address telematics applications but even here for asset tracking this is the second priority certainly this is very often a combination with short TTFF

Jamming recognition, mitigation, removalEspecially automotive telematics suppliers ask for that it is already normal in GSM products

Galileo supportNot a big issue today, but especially in Europe, customers are asking

SiRFawareTM - BasicsQ: What is SiRFawareTM good for?A: SiRFawareTM keeps the module in a state of readiness for rapid navigation for long periods!

Q: When and how can I start using SiRFawareTM?A: SiRFawareTM mode can be entered after an initial position calculation by software command!

Q: How is SiRFawareTM able to accomplish this?A: SiRFawareTM will try to maintain position, time, frequency, and Ephemeris!

Q: Can I further improve SiRFawareTM?A: SiRFawareTM can even be combined with Extended Ephemeris methods!PRELIMINARY

SiRFawareTM PowerData Collection (re-load of Ephemeris)Every 30 minutes for ~ 18s @ 40mACalc. average: 40mA x 18s / (30 x 60s) = 400ATargeted average: < 500AResults so far: ~ 300A

Capture / Update (time, frequency, ... maintenance)Every minute for ~ 250ms @ 30mA (worst case)Calc. average: 30mA x 250ms x 30 / (30 x 60s) = 125ATargeted average: < 500AResults so far: < 300APRELIMINARY

Summary / FeedbackKeep in mindWe are an early adopter, so there might still be a change in design between the samples and production modulesMany features will be enabled with new firmware updatesDocumentation is not perfect yet and CSR will release its documentation in March only - but we can start!Further information to follow shortlyYour feedback is appreciated

Thanks!
