some verification• Pricing available through your sales interface• Press release to be distributed shortly


First Prototype Production


Receiver Requirements

• Shortest TTFF– Customers do not care about channels, correlators, Ephemeris (extended or

not) – they want a fix NOW

• Highest sensitivity– Fix under all conditions – no worries about an antenna

• Lowest Power consumption– We 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, removal– Especially automotive telematics suppliers ask for that – it is already normal

in GSM products

• Galileo support– Not a big issue today, but especially in Europe, customers are asking


SiRFstarIV

• Tracks up to 8 jammers• Removes jammers prior to

correlation

• -163 dBm tracking• -160 dBm navigation• -148 dBm acquisition (autonomous)• SiRFnav™ navigation accuracy

• 10 power domains• 5 power states• 35 mW full power tracking• 8 mW trickle power @1Hz• 50-500uA continuous availability

mode• Integrated temperature sensor

• Smart Sensor support• Sensor interrupt support• Multi-master I2C bus• SiRFDRive support• SiRFDiRect support

SiRFawareTM - Basics

Q: 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!

SiRFawareTM – Power PRELIMINARYPRELIMINARY

• Data Collection (re-load of Ephemeris)– Every 30 minutes for ~ 18s @ 40mA– Calc. average: 40mA x 18s / (30 x 60s) = 400µA– Targeted average: < 500µA– Results so far: ~ 300µA

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

Implementation

• Vcc should be always ON!• Toggle ON_OFF from LOW to HIGH to wake up after power on….• Use software command to initiate and get back from SiRFawareTM

and other low power modes…• Necessary configuration for UART mode:

Summary / Feedback

• Keep in mind– We are an early adopter, so there might still be a change

in design between the samples and production modules– Many features will be enabled with new firmware updates– Documentation is not perfect yet and CSR will release its

documentation in March only - but we can start!

• Further information to follow shortly• Your feedback is appreciated

• Thanks!
